Flight Crew Licensing — Page 87, Lesson 139

I want to walk you through the medical side of flight crew licensing now. This is where we move from the paperwork of licences to the physical and mental fitness that underpins them. Let's start with the ICAO medical certificates, because everything else hangs off this. ICAO defines three medical assessment classes, and each one is tied to a specific type of licence. Class 1 is for the commercial pilot licence, and also for the flight engineer and navigator licences. That's the highest standard, because those are the people operating commercially. Class 2 is for private pilot licences, and note it explicitly includes glider and free balloon pilots. Class 3 is different — it's not for pilots at all, it's for Air Traffic Controllers. So when you hear someone talk about a Class 1 medical, you know immediately they're talking about a commercial pilot, and the standard is set accordingly. Now, once the examination is done, we come to what's called aeromedical disposition. This is simply the decision about what happens next. After completion of the examination, the applicant shall be advised whether they are fit, unfit, or referred to the Authority. So there are three possible outcomes: you're fit, you're unfit, or your case gets referred upward to the Authority for a decision. The key player here is the authorized medical examiner — the AME. That's the doctor who is specifically authorised to conduct these aviation medical examinations. The AME shall inform the applicant of any conditions — and note the wording, it says medical, operational, or otherwise — that may restrict flying training and/or the privileges of any licence issued. So the AME isn't just saying yes or no; they're flagging anything that could limit what you're allowed to do, either during training or once you hold the licence. There's a specific scenario I want you to note carefully. In the event that a restricted medical certificate is issued which limits the holder to exercise pilot-in-command privileges only when a safety pilot is carried, the authority will give advisory information for use by the safety pilot in determining the function and responsibilities. Let me unpack that. A restricted certificate might say you can only act as pilot-in-command if there's a safety pilot on board. In that case, the Authority provides advisory information so the safety pilot knows what their function and responsibilities actually are. So the safety pilot isn't just sitting there — they have a defined role, and the Authority spells it out. Now let's talk about the periodic medical examination. The annual medical examination is effectively a health check. That's the key phrase — it's a health check, not just a re-test of the original exam. And it takes into account the aging process since the issue of the original certificate. So the point is that as you get older, your body changes, and the annual exam is designed to catch that. Providing the pilot has medical examinations at the required intervals, the aging process will be taken into account. So the system only works if you keep up the schedule — if you attend at the required intervals, the examiner can track how you're changing over time. Now here's a hard rule under the JAA regulations. Extensions of medical certificate validity are not permitted. And I want to be precise about what that means — an extension here means a deferment of the medical examination. So you cannot simply push back your medical exam and keep flying on the old certificate. Under JAA rules, that's not allowed. The exam happens when it's due. Finally, we come to a decrease in medical fitness. This is about what happens between your scheduled exams, if you become unwell. Licence holders are not to exercise the privileges of their licences if they are aware that they are unwell. So the moment you know you're unwell, you stop exercising the privileges — you don't fly. In such circumstances, you are to seek the advice of the Authority or the AME. So you don't just self-ground and wait; you go and get advice from the Authority or your AME. And the excerpt lists specific circumstances that trigger this. Hospital or clinic admission for more than 12 hours. A surgical operation or invasive procedure. The regular use of medication. And the need for regular use of co — and that's where the excerpt cuts off, but you can see the pattern: these are all situations where your body is no longer in the state it was when you were certified. The principle is that your medical certificate reflects a certain level of fitness, and if something changes that fitness, you have an obligation to stop flying and seek advice. So the whole structure here is: ICAO sets the classes, the AME makes the disposition, the annual exam tracks aging, and the pilot has a personal duty to report any decrease in fitness between exams. That last part is the one that really matters operationally — it's on you to recognise when you're not fit and to act on it.
