The Medical Certificate Breakdown: What Pilots Need to Know
Pilot medical certificates can be confusing because several systems overlap. Pilots hear terms like first-class, second-class, third-class, BasicMed, AME, MedXPress, special issuance, SODA, deferral, and medical limitations. Each one matters, but they do not all mean the same thing.
This article explains the FAA medical certification system in a practical way. It is not meant to determine whether someone is medically qualified to fly. Instead, it explains what the different medical certificates are generally used for, how medical privileges change over time, what BasicMed is, and where pilots can find official FAA resources.
Whether you are starting flight training, working toward a professional aviation career, returning to flying after time away, or trying to better understand your options, this breakdown will help you understand the major pieces.
Important Note
This article is for educational purposes only. It is not legal or medical advice. I am not a licensed attorney or physician, and this article should not be used to determine whether you are medically qualified to fly. FAA medical certification can involve both medical and regulatory issues. Always verify current FAA regulations, review official FAA medical guidance, and speak with a qualified Aviation Medical Examiner, physician, or attorney when appropriate.
Pilot Certificate vs. Medical Certificate
A pilot certificate and a medical certificate are not the same thing.
Your pilot certificate says what pilot privileges you hold. Your medical qualification helps determine whether you are medically eligible to use those privileges. You can think of a pilot certificate as being similar to a driver's license. Is it a standard license or a commercial driver's license? Each has its own specific privileges and laws regulating what you can do. A medical certificate is like a doctor's note stating you are medically fit to drive your car for a period of time.
For example, a person may hold a private pilot certificate, a commercial pilot certificate, or an airline transport pilot certificate. However, that pilot still needs the proper medical qualification for the type of operation being conducted. Someone flying for an airline is subject to a more thorough medical evaluation more often compared to a private pilot flying themselves for fun on the weekends in smaller aircraft carrying only a few passengers.
The required medical qualification depends on the type of flying. Some pilots need a traditional FAA medical certificate. Some may qualify under BasicMed. Some sport pilots may be able to use a valid U.S. driver’s license instead of an FAA medical certificate, depending on the operation. FAA medical certificate requirements and exceptions are all found in 14 CFR § 61.23.
The Three Main Classes of FAA Medical Certificates
The FAA has three main classes of medical certificates: first-class, second-class, and third-class. Each class is connected to different pilot privileges. A higher-class medical can usually be used for lower-level privileges while it remains valid for those privileges. If you have a valid first-class medical certificate, you can take advantage of first, second, and third-class privileges all at the same time if you are within the valid time period.
One important detail: the medical certificate itself does not physically change classes over time. If your certificate says First-Class Medical Certificate, it will still say First Class on the certificate. It does not turn into a second-class or third-class medical. What changes over time are the privileges you may exercise with that medical certificate.
Pilots often say a medical certificate “steps down,” but it is more accurate to say the medical privileges are reduced over time. The certificate itself does not physically change. For example, if a pilot receives a First-Class Medical Certificate, that paper will still say First Class even after the pilot is no longer eligible to exercise first-class privileges.
The privileges attached to that certificate are what change based on the pilot’s age, the type of operation being conducted, and the time that has passed since the medical exam. So, if a pilot pulled that same certificate out of their flight bag 12 months later, it would not magically say “Third Class.” It would still be a printed First-Class Medical Certificate, but the pilot may only be able to use it for lower-level privileges at that point, depending on the circumstances and the amount of time that has passed from initial issuance.

First-Class Medical Certificate
A first-class medical certificate is usually associated with airline pilot operations. Under 14 CFR § 61.23, a first-class medical certificate is required when exercising pilot-in-command privileges of an airline transport pilot certificate. It is also required in certain Part 121 operations, depending on the pilot’s role and age.
A first-class medical may be used for airline transport pilot privileges, commercial pilot privileges if still valid for second-class privileges, and private pilot privileges if still valid for third-class privileges.
For airline transport pilot privileges, a first-class medical generally lasts 12 calendar months if the pilot was under age 40 on the date of the exam and 6 calendar months if the pilot was age 40 or older on the date of the exam.
For pilots under age 40, first-class and second-class privileges generally expire at the end of the same 12-calendar-month period. The remaining time, if applicable, applies to third-class privileges.
Second-Class Medical Certificate
A second-class medical certificate is usually associated with commercial pilot privileges. Under 14 CFR § 61.23, a pilot generally must hold at least a second-class medical certificate when exercising commercial pilot privileges in an aircraft, with certain exceptions listed in the regulation.
A second-class medical may be used for commercial pilot privileges, private pilot privileges, student pilot privileges, recreational pilot privileges, and flight instructor privileges when acting as PIC or as a required flight crewmember.
For commercial pilot privileges, a second-class medical is generally valid for 12 calendar months. After that, it may still be valid for private pilot-level privileges if it remains within the third-class medical duration period.
For example, if a 25-year-old pilot gets a second-class medical, that medical is generally valid for commercial pilot privileges for 12 calendar months. After that, it may still be valid for private pilot privileges until the third-class privilege period runs out.
Third-Class Medical Certificate
A third-class medical certificate is commonly used for student pilots, private pilots, recreational pilots, and some flight instructor operations.
Under 14 CFR § 61.23, a pilot generally must hold at least a third-class medical certificate when exercising student, recreational, or private pilot privileges unless operating under an allowed alternative, such as BasicMed or certain sport pilot rules. A third-class medical may also be required for flight instructor privileges when acting as PIC or as a required flight crewmember.
For private pilot-level privileges, a third-class medical generally lasts 60 calendar months if the pilot was under age 40 on the date of the exam and 24 calendar months if the pilot was age 40 or older. The age is based on the pilot’s age on the date of the medical examination, not their age later during the certificate period.
Quick Medical Certificate Comparison
The FAA provides a helpful quick-reference table in 14 CFR 61.23(d) to determine how long different privileges are valid, depending on the type of medical certificate you possess.

Calendar Month Expiration
FAA medical certificate durations are based on calendar months counted from the month the medical examination was completed.
This means the expiration is usually at the end of the applicable month, not the exact day of the exam. As you know, a "month" is not equal in length month over month. Instead of trying to determine how many exact days it has been since your medical exam, the FAA allows some wiggle room by having privileges expire at the end of the "Calendar" month.
For example, if a pilot completes a medical exam on April 3, the month of April is the starting point. A 12-calendar-month privilege period would generally run through the end of April the following year. A 60-calendar-month privilege period would generally run through the end of April five years later.
For a pilot under age 40 who receives a first-class medical, both first-class and second-class privileges generally expire at the end of 12 calendar months. The remaining 48 months apply only to third-class privileges. Just remember! All expiration limits reference the month you completed your medical!
The Pilot’s Responsibility to Self-Ground
A valid medical certificate does not automatically mean a pilot is fit to fly every day. Under 14 CFR § 61.53, a pilot may not act as pilot in command or as a required flight crewmember if they know, or have reason to know, of a medical condition that would make them unable to meet the medical requirements or safely operate the aircraft. This also applies to operations that do not require a medical certificate if the pilot knows, or has reason to know, of a condition that would make them unsafe to operate.
This is where personal judgment matters. If you are sick, taking medication, recovering from a medical event, dealing with a new diagnosis, or unsure about your fitness to fly, speak with an AME or qualified physician before flying.
A helpful FAA resource is the Do Not Issue / Do Not Fly medication guidance. The FAA uses Do Not Issue for medications or medication classes where an AME generally cannot issue a medical certificate without FAA clearance. Do Not Fly refers to medications that may temporarily make a pilot unsafe to fly until the medication has been stopped and enough time has passed. Some medications may cause drowsiness, slow reaction time, affect judgment, or impair thinking even if the pilot feels “fine.”
A common rule of thumb pilots often hear is the 5-dosage-period rule. This means waiting at least five times the normal dosing interval after the last dose before flying. For example, if a medication is taken every 6 hours, a pilot would wait at least 30 hours after the last dose before flying. If it is taken once every 24 hours, the waiting period would be at least 5 days. This is only a general rule of thumb, not a guarantee that the pilot is safe to fly. The medication, the side effects, the reason the medication was taken, and the pilot’s overall condition still matter.
Pilots should also use caution with common over-the-counter medications. Cold medicine, allergy medicine, sleep aids, pain medication, and other routine drugs can still affect flight safety. You should never take medication just to feel well enough to fly. If the medication wears off or if the condition gets worse in flight, you could quickly find yourself in an unsafe situation with limited options.
As I tell my students, it is much better to be on the ground wishing you were flying than flying wishing you were on the ground. If you are sick or actively treating a condition that could affect your ability to fly safely, do not fly. Please be especially careful with any form of sinus blockages. Changes in pressure due to altitude can cause severe discomfort.
The safest approach is simple: do not treat a current medical certificate as automatic permission to fly. The certificate shows that you met the medical standard at the time it was issued. It does not guarantee that you are safe to fly today. If there is any doubt, self-ground, check FAA medical guidance, and talk with an AME before acting as PIC or a required crewmember.
When Does a New Pilot Need a Medical?
A new pilot usually does not need a medical certificate before taking their first flight lesson with a flight instructor. Under 14 CFR § 61.3(c), the medical certificate requirement applies when a person is serving as a required pilot flight crewmember, such as solo. During normal dual instruction, the student receiving instruction is not acting as pilot in command or serving as a required flight crewmember.
The medical typically becomes important before the student acts as pilot in command, such as before solo flight. Under 14 CFR § 61.87, a student pilot must meet the solo requirements before operating the aircraft alone. For most student pilots training toward a private pilot certificate in an airplane, that means obtaining at least a Third-Class Medical Certificate unless an allowed alternative applies.
This is why it is possible to begin flight training before completing the FAA medical process. However, waiting too long can create problems if the medical is delayed, deferred, or requires additional FAA review. The FAA suggests getting the medical before beginning flight training so a student can find out early if a medical condition may prevent them from becoming a pilot.
If someone plans to fly as a career, I usually recommend trying to obtain a First-Class Medical Certificate before beginning, or at least very early in training. A third-class medical may be enough to begin training and work through the early certificates and ratings, but it does not answer the bigger career question: Can I qualify for the medical certificate I will eventually need to use professionally?
It is much better to find that out before spending the time and money required to complete flight training. I have personally seen students complete the necessary training, become a CFI, and build their early aviation career while holding a third-class medical, only to later be denied, deferred, or delayed when applying for a first-class medical certificate. That does not always mean the pilot’s career is over, but it can create serious delays, extra costs, and a lot of uncertainty.
For someone who wants to fly themselves, their family, or their friends, but not act as a pilot for hire, a Third-Class Medical Certificate may be completely appropriate. For someone planning to fly for an airline or another professional operation that requires first-class privileges, it is smart to address the first-class medical question early.
Which Medical Should a Pilot Get?
The medical certificate a pilot should consider depends on their long-term goal. Not every pilot needs a first-class medical, but it is important to choose a medical path that matches what the pilot wants to do.

BasicMed
BasicMed is another way for certain pilots to meet FAA medical requirements without holding a current FAA medical certificate.
BasicMed is not a fourth-class medical certificate. It is a separate option for certain types of general aviation flying. It can be helpful for pilots who have already held an FAA medical certificate before and are flying aircraft that fit within the BasicMed limits.
To use BasicMed, a pilot generally must have held an FAA medical certificate after July 14, 2006. The pilot also needs a valid U.S. driver’s license, must complete a BasicMed physical exam with a state-licensed physician, and must complete an approved online medical education course.
If a pilot has never held an FAA medical certificate, they usually cannot start with BasicMed. They would first need to apply for and receive an FAA medical certificate at least one time.
BasicMed Requirements
To operate under BasicMed, a pilot generally must:

The pilot’s most recent medical certificate also matters. If the most recent FAA medical application was denied, or if the medical certificate was suspended or revoked, the pilot may not be able to use BasicMed until that issue is resolved. If there is any doubt, the safest answer is to check with an AME or review the current FAA guidance before flying under BasicMed.
BasicMed Renewal Timing
BasicMed has its own timing requirements.
The BasicMed medical education course must be completed every 24 calendar months.
The BasicMed physical examination checklist must be completed every 48 months.
This is different from a traditional FAA medical certificate, so pilots should track the dates carefully.
What Can You Fly Under BasicMed?
Under FAA BasicMed guidance, the aircraft must be authorized under federal law to carry not more than 7 occupants and have a maximum certificated takeoff weight of not more than 12,500 pounds. The operation may carry no more than six passengers, may be conducted under VFR or IFR, must remain at or below 18,000 feet MSL, must not exceed 250 knots, and may not be operated for compensation or hire.
BasicMed is mainly designed for certain general aviation operations. It is not a replacement for the medical certificate needed for airline flying or most commercial operations.
BasicMed and Flight Instructors
BasicMed can also apply to some flight instruction situations. This part can be confusing because flight instructors may be paid for instructing.
The FAA has recognized that a flight instructor may use BasicMed in certain instructional operations, as long as the aircraft and the flight meet the BasicMed requirements. In other words, being paid to instruct does not automatically prevent BasicMed from being used.
However, BasicMed does not work for every instructional situation. The aircraft, number of people on board, speed, altitude, location, and type of operation still have to fit within the BasicMed rules. If the flight does not fit those limits, BasicMed may not be enough.
BasicMed and Pilot Examiners
BasicMed may also be used by certain pilot examiners when conducting a practical test or proficiency check, but only if the aircraft and operation meet the BasicMed limits. Under 14 CFR § 61.23(c)(1)(viii), a person may use a U.S. driver’s license instead of a current FAA medical certificate when serving as an examiner and administering a practical test or proficiency check, as long as the flight is conducted under the conditions and limits of 14 CFR § 61.113(i)
Sport Pilot Medical Rules
Sport pilot medical rules are another area where pilots may hear incomplete information. Some pilots hear “you only need a driver’s license” and assume that applies to any pilot, any aircraft, or any type of flying. That is not correct.
For certain sport pilot operations, a pilot may be able to use either a valid FAA medical certificate or a current and valid U.S. driver’s license as their medical qualification. If the pilot uses a driver’s license, they must follow any restrictions on that license and any applicable motor vehicle orders. This is covered under 14 CFR § 61.23(c)(2).
This does not mean every pilot can fly every aircraft with only a driver’s license. Sport pilot privileges have their own aircraft limits, operating limits, and endorsement requirements. Those limits are addressed in 14 CFR § 61.303 and related sport pilot rules.
A pilot using sport pilot driver’s license medical qualification still has the responsibility to self-ground. Under 14 CFR § 61.53, a pilot may not act as pilot in command or as a required flight crewmember if they know, or have reason to know, of a medical condition that would make them unsafe to operate.
What Is an AME?
AME stands for Aviation Medical Examiner.
An AME is a physician designated by the FAA to perform FAA medical examinations. A pilot does not go to just any doctor for a traditional FAA medical certificate. The exam must be completed by an FAA-designated AME. The FAA provides an AME locator tool that allows pilots to search for Aviation Medical Examiners in their area.
Where to Find an AME
Pilots can find an AME through the FAA’s AME locator.
Click the link here and select "AME" as the designee type, then "Location Search."I recommend filling out only the City and State fields in the search criteria.
Find an Aviation Medical Examiner
The FAA medical certification page also provides access to FAA MedXPress and other medical certification information. MedXPress is the online application system pilots use before seeing an AME for a traditional FAA medical certificate.
What Is MedXPress?
MedXPress is the FAA’s online medical application system.
Before going to an AME for a traditional FAA medical certificate, the pilot completes the medical application through MedXPress. The pilot then receives a confirmation number to provide to the AME. This step matters because once the application is submitted and the AME begins the exam process, the pilot is formally in the FAA medical certification process.
Be Careful Before Submitting MedXPress
Pilots should not guess their way through MedXPress.
If a pilot has a complicated medical history, current or past medication use, a mental health diagnosis, a DUI or alcohol-related event, a surgery, a major illness, or anything else that may require FAA review, it may be smart to consult an experienced AME before starting the formal exam process. They can provide guidance on which documents will be required before the official appointment. This could help prevent a deferment.
This does not mean pilots should hide information. They must be honest. It means they should be prepared before entering the FAA medical system. A good rule to follow: do not hide anything, but do not walk into the process unprepared. If you hide your medical issues and they are found at a later date, you could face serious consequences.
Medication Matters
Some medications may affect a pilot’s ability to fly legally or safely.
This article does not determine whether a medication is safe, approved, or acceptable for flight. If you are taking medication or have questions about a medical condition, speak with an AME or qualified physician before flying.
A medication may be acceptable for normal daily life but still create concerns for flying. The FAA may consider the medication itself, the condition being treated, side effects, dosage, stability, and supporting medical documentation.
Limitations Printed on the Medical Certificate
Some pilots have limitations printed on their medical certificate. These limitations must be followed.
Common examples may include:
Must wear corrective lenses
Must have available glasses for near vision
Not valid for night flying or by color signal control
These limitations are not suggestions. They are part of the medical certificate.
If a pilot’s medical certificate says they must wear corrective lenses, then they need to comply with that limitation while exercising privileges that require the medical.
Color Vision Limitations
Color vision is one area where a pilot may receive a limitation.
A medical certificate may include language such as:
Not valid for night flying or by color signal control
This can affect the pilot’s privileges. In some cases, a pilot may pursue additional FAA evaluation related to color vision. Depending on the situation, that may involve further testing or a possible FAA process.
The important point is that limitations on a medical certificate need to be understood and followed. If a pilot is unsure what a limitation means, they should contact an AME or the FAA for guidance.
What Is a Medical Deferral?
A medical deferral happens when the AME cannot issue the medical certificate at the appointment and must send the application to the FAA for review.
A deferral does not automatically mean denial. It usually means the FAA needs more information before making a decision.
The FAA may ask for medical records, doctor statements, test results, additional explanations, or follow-up documentation. After review, the FAA may issue the medical certificate, request more information, issue through special issuance, or deny the application. This typically takes a long time, depending on the issue. It's important to discuss potential issues before your appointment so you can gather any necessary info needed.
Deferral vs. Denial
Deferral: The AME cannot issue at the appointment, so the FAA must review the application
Denial: The FAA determines the applicant does not qualify for the medical certificate at that time
A deferral can be frustrating, but it is not the same as being denied, so don't panic. Most deferrals can be resolved with time.
Special Issuance Medical Certificate
A special issuance may be used when a pilot does not meet the normal FAA medical standards, but the FAA determines the pilot may still be able to safely perform the duties allowed by the medical certificate.
This does not mean the condition is ignored. It means the FAA may allow medical certification after reviewing the condition, the pilot’s records, and the risk involved. Under 14 CFR § 67.401, the FAA may issue a medical certificate to a person who does not meet the normal medical standards if that person has a valid authorization and is otherwise eligible.
A special issuance may require additional medical records, specialist reports, follow-up testing, periodic review, ongoing documentation, or FAA approval before the AME can issue the certificate. Special issuance can also take time, so pilots should not wait until the last minute if they know they have a condition that may require FAA review.
For example, a pilot with a history of a heart condition, certain mental health conditions, diabetes requiring specific review, or another condition that does not automatically meet the normal FAA medical standard may need a special issuance. The FAA may want records from the treating doctor, test results, medication information, and proof that the condition is stable enough for safe flight.
What Is SODA?
SODA stands for Statement of Demonstrated Ability.
A SODA may be granted when a pilot has a medical condition that is static or nonprogressive, meaning it is not expected to worsen. The FAA explains that a SODA may be granted instead of an authorization when the person has a static or nonprogressive disqualifying condition and has been found capable of performing airman duties without endangering public safety.
A SODA may be connected to a physical limitation, color vision issue, or another condition that is not expected to worsen. Depending on the situation, the FAA may require a demonstration, medical flight test, practical test, or other evaluation. Under 14 CFR § 67.401, a person who receives a SODA after a special medical flight test or practical test generally does not have to repeat that test during later medical exams unless the FAA believes the condition has, or may have, gotten worse.
For example, a pilot with a stable vision limitation, certain color vision issues, hearing loss in one ear, or the loss of use of a limb may be able to demonstrate that they can still safely operate an aircraft. If the FAA determines the pilot can safely perform the required duties, a SODA may allow the AME to issue the appropriate class of medical certificate in the future, as long as the condition has not changed.
Special Issuance vs. SODA
Special Issuance: FAA approval for a medical condition that may need review or monitoring
SODA: FAA recognition that a pilot has demonstrated ability with a stable condition
Special issuance often involves continued monitoring. SODA usually applies to a stable condition where ability has already been demonstrated.
BasicMed and Special Issuance Conditions
Some medical conditions require a pilot to complete a one-time special issuance process before using BasicMed. This is an area where pilots need to be careful. BasicMed does not mean a pilot can skip the FAA process for every medical issue.
The FAA lists certain mental health, neurological, and cardiovascular conditions that require a one-time special issuance before a pilot may operate under BasicMed. These conditions are addressed in 14 CFR § 68.9 and on the FAA’s BasicMed guidance page.
For example, a pilot with a history of certain heart conditions, epilepsy, bipolar disorder, psychosis, or substance dependence may need FAA review and a special issuance before using BasicMed. This does not mean every pilot with one of these conditions is permanently grounded. It means the FAA may need to review the condition first and determine whether the pilot can safely operate.
If the pilot already received a special issuance for that condition, and the condition has not changed, they may not have to go through that same one-time process again. However, if the condition is new, has changed, or the pilot has never received a special issuance for it, they should not assume BasicMed applies automatically.
If a pilot has a significant medical history, the safest step is to review the official FAA BasicMed guidance and speak with an AME before flying under BasicMed. A quick conversation before flying is much better than finding out later that the pilot did not actually qualify.
Common Medical Certificate Confusions
“Do I need a medical before my first flight lesson?”
Usually, no. A new pilot can typically begin dual instruction with a flight instructor before holding a medical certificate. The medical usually becomes necessary before solo flight if training toward private pilot privileges.
“Does my first-class medical become a second-class medical?”
No. The certificate still says first class. The class printed on the certificate does not change. What changes are the privileges the pilot may exercise with that certificate.
“Is BasicMed a fourth-class medical?”
No. BasicMed is not a fourth-class medical certificate. It is an alternative medical qualification pathway for certain pilots and operations.
“Can I use BasicMed if I have never held an FAA medical?”
Generally, no. To use BasicMed, a pilot generally must have held an FAA medical certificate after July 14, 2006.
“Is a deferral the same as a denial?”
No. A deferral means the FAA needs to review the application. A denial means the FAA determined the applicant does not qualify at that time.
“Does the medical expire on the exact day of the exam?”
Usually, no. Medical certificate duration is generally counted by calendar months. This usually means the privileges remain valid through the end of the applicable month.
“Is a regular doctor the same as an AME?”
No. A regular physician may be involved in your healthcare, and a state-licensed physician is used for the BasicMed physical exam checklist. For a traditional FAA medical certificate, the exam must be completed by an FAA-designated AME.
“Do limitations on the medical certificate matter?”
Yes. If the medical certificate has a limitation printed on it, the pilot must follow it.
“Can I fly while taking medication?”
Do not guess. Some medications may be acceptable, and others may create FAA or safety concerns. Ask an AME or qualified physician before flying.
Official FAA Resources to Know
Pilots should know where to find official FAA medical information. Helpful FAA resources include the FAA Medical Certification page, MedXPress, the FAA AME Locator, the FAA BasicMed page, and the FAA Guide for Aviation Medical Examiners. The FAA’s AME locator provides an up-to-date listing of Aviation Medical Examiners based on search criteria selected by the user.
Practical Advice Before Starting the FAA Medical Process
Before going to an AME, take the process seriously. Review your medical history, current medications, past medications, surgeries, mental health history, alcohol-related or drug-related events, vision or color vision concerns, and any diagnosis that may require FAA review.
This does not mean hide anything. Pilots must be honest. It means the pilot should be prepared before entering the formal FAA medical process.
If you think something might be an issue, ask before you submit.
Final Thoughts
Pilot medical certification can feel overwhelming because several systems overlap. Traditional FAA medical certificates, BasicMed, sport pilot medical rules, MedXPress, special issuance, and SODA all serve different purposes.
A first-class medical is generally connected to airline transport pilot privileges. A second-class medical is generally connected to commercial pilot privileges. A third-class medical is commonly used for student, recreational, and private pilot privileges. BasicMed and sport pilot rules may provide alternatives in certain general aviation operations, but they do not apply to every situation.
The key is to match the medical requirement to the type of flying being conducted. If there is any uncertainty about a medical condition, medication, limitation, or FAA application question, use official FAA resources and speak with a qualified AME or physician before making assumptions.
