FAA Medical Certificates for Flight Schools: Class 1, 2, 3, and BasicMed

A renter walks up to the desk on a Saturday afternoon, current on his flight review, current on his takeoffs and landings, and asks for a 172 for an hour in the practice area. The dispatcher pulls his medical from the file and the date on the third-class certificate is two months past the expiration the regulation gives him for his age. He is qualified, he is rated, he is current on everything else, and he cannot legally act as pilot in command. The school did not write the date and is the party that has to send him home anyway.

A medical certificate is the cleanest go-or-no-go field on a pilot record. It is a date and a class, and the pilot either has one or does not. What complicates it for a flight school is that the rule for which class is required and how long it lasts depends on what the pilot is doing in the airplane and how old they were at the exam. Three classes, plus BasicMed, plus a student pilot certificate that is not a medical, all feed into the same dispatch decision.

What 14 CFR 61.23 Actually Says

14 CFR 61.23 ties pilot operations to medical certificate classes. A first-class medical is required for ATP-certificate operations. A second-class medical is required to act as PIC of an operation that requires a commercial certificate, the most common example at a school being a CFI flying for hire on the primary instruction roster. A third-class medical is required to act as PIC of any flight that requires only a private certificate, including student solo.

Sport pilot privileges, recreational privileges in limited situations, and BasicMed all sit alongside the class system as alternatives. They do not replace 61.23. They are routes within it, each with their own qualifying conditions and operational limits.

Duration Cuts at Age 40

The duration of each class is what trips up most dispatchers. A first-class medical, for the privileges of an ATP operation, lasts six calendar months if the pilot was at or over 40 at the date of the exam, and twelve months if they were under 40. A second-class medical, for commercial privileges, lasts twelve calendar months regardless of age. A third-class medical lasts twenty-four calendar months for a pilot at or over 40 at exam time, and sixty calendar months for a pilot under 40.

Every one of those windows is measured to the last day of the relevant calendar month, the same calendar-month math behind the flight review under 14 CFR 61.56 and the CFI certificate renewal under 14 CFR 61.197. A medical exam on March 14 covers the pilot through the end of March in whichever year the duration runs out. A school that tracks medicals to the exam date instead of the end of the month is going to ground a pilot two weeks earlier than the regulation requires.

The other detail in 61.23 worth holding is that a higher-class medical, once it ages out of the operations it was issued for, continues to satisfy a lower class until that lower class also expires. A 41-year-old commercial pilot whose first-class exam was nine months ago no longer has first-class privileges, but the same paperwork still covers him for second-class operations for three more months, and for third-class operations for fifteen more months after that. The dispatcher chases a new exam only when the lowest applicable class is the one that runs out.

Student Pilot Certificate Is Not the Medical

A student pilot certificate and a medical certificate are two separate documents that the FAA has, since 2016, partially intertwined at the application stage. The student pilot certificate is issued out of the FAA Airman Registry through IACRA and does not expire as a certificate. The medical is still the FAA-form-8500 exam an Aviation Medical Examiner performs, and it is the medical that authorizes the student to solo.

For a flight school, the operational consequence is that holding a student pilot certificate proves nothing about whether the student is currently medically qualified to fly. The two records have to be tracked separately. A student with an active student certificate and a third-class medical that expired last quarter cannot solo. A student whose medical is current but whose solo endorsement under 14 CFR 61.87 has lapsed past 90 days also cannot solo. Both records have to be live, both dates have to be inside their window, and the dispatcher releasing the airplane has to be looking at both.

BasicMed and What It Lets a Private Pilot Skip

BasicMed is the alternative the FAA opened in 2017 for private and recreational operations. A pilot who has held a regular FAA medical at any time after July 14, 2006 can fly under BasicMed without renewing that medical, provided they hold a U.S. driver's license, complete an online medical education course every twenty-four calendar months, and see any state-licensed physician for a comprehensive checklist exam every forty-eight calendar months. The privilege ceiling is real: not more than six occupants, not above 18,000 feet, not faster than 250 knots, and not for compensation or hire as pilot in command.

A renter current under BasicMed can rent the school's airplanes, conduct a flight review, and operate from the school's field on the same terms as a third-class-medical holder, as long as the operation stays inside the BasicMed limits. What BasicMed does not do is authorize CFI operations for hire, commercial operations, or student solo. A school whose roster mixes third-class and BasicMed renters needs both fields on the pilot record, with the BasicMed education-course date and the physician-exam date tracked separately, because they expire on separate clocks.

CFI Medicals and the Question Nobody Asks

A common surprise in the CFI hiring conversation is that a flight instructor giving instruction in an aircraft they are not the required pilot in command of does not need a medical for the instructing function itself. The FAA's published guidance is that a CFI may give flight instruction as long as the student is the acting pilot in command, the student holds the required medical, and the CFI is qualified as a CFI. A second-class medical is the operational standard at most schools because most CFIs do act as PIC during checkouts, ferry flights, and discovery flights, and because almost every school's insurance policy requires it whether the regulation does or not.

The practical answer is that the school's policy and its insurance carrier set the medical class the CFI bench actually carries, not 61.23 on its own. Treat the medical as a credential to track per CFI on the same record as the certificate expiration.

Building Medical Tracking Into Dispatch

The data is small. For each pilot on the roster, store the class of medical they hold (first, second, third, or BasicMed), the date of the exam, the pilot's date of birth, and, for BasicMed, the dates of the medical education course and the physician checklist exam. From that the booking system can compute the calendar-month expiration for each class privilege and surface the date the dispatcher cares about: the day the lowest class applicable to the operation booked is no longer valid.

A modern scheduling platform like HangarOS treats medical class as one more structured field on the pilot record, evaluated at booking approval rather than at the airplane. A renter whose medical expires in 30 days appears as a soft flag. A renter who tries to book a flight that lands after their expiration appears as a hard block. The information already exists on the certificate. Putting it in front of the person releasing the keys is the rest of the job.

A Date the School Should Never Be Surprised By

A medical certificate is the regulation everyone in the building treats as the pilot's private affair, right up until the moment the front desk has to send a current, qualified, paid-up renter home because the date in the file ran out two weeks ago. The classes are not complicated and BasicMed only adds a handful of extra fields to a record the school already keeps. Tracking medical dates with the same discipline a school applies to currency, endorsements, and instructor credentials is what closes the gap between a pilot who is legal in theory and a pilot the dispatcher can hand the keys to today.
