Whether you're renewing a Class 2 certificate for weekend flying or sitting your first Class 1 on the road to a commercial licence, a pilot medical examination is a milestone that rewards preparation. The good news is that there are few surprises: the process is structured, predictable and designed to confirm that you're fit to fly rather than to catch you out. Here's what actually happens, stage by stage.

Know Which Medical You Need

The examination you book depends entirely on the licence you hold or are applying for, and the requirements differ in depth and frequency.

• Class 1 – for commercial pilots and those training towards a professional licence. The most thorough assessment, with the shortest validity periods.
• Class 2 – for private pilots flying on a PPL. Shorter, simpler and valid for longer, especially for younger holders.
• Class 3 – for air traffic controllers, with its own set of sensory and cardiovascular standards.
• LAPL medical – for light aircraft pilots, usually handled through a self-declaration or an assessment with your own GP.

Validity is age-dependent: a Class 1 might last twelve months under 40 but drop to six months later on, while a Class 2 can run for several years for a younger pilot. Check your renewal date well in advance — flying on an expired certificate, even by a day, is a serious matter.

Before the Appointment: Documents and Preparation

Arriving with the right paperwork saves everyone time and prevents your assessment being cut short. Bring the following:

• Photo identification – a passport or photocard driving licence.
• Your previous medical certificate, if you hold one.
• Your spectacles or contact lenses, plus the prescription if you have it, even if you only wear them occasionally.
• A full list of medications, including doses, and any supplements you take regularly.
• Your GP's name, address and contact details, together with any specialist letters or recent test results relating to an existing condition.
• Payment – most examiners charge directly, and fees vary by class.

Prepare your body as well as your bag. Get a decent night's sleep, avoid alcohol for at least twenty-four hours and skip the strong coffee beforehand, since caffeine can nudge your blood pressure upwards. Take your usual prescribed medication unless you've been told otherwise. If you have a long-standing condition, request your consultant's latest clinic letter in advance — it can turn a drawn-out referral into a straightforward decision.

The Examination Itself: History and Baseline Measurements

An initial Class 1 typically takes two to three hours; a Class 2 renewal is usually done in under an hour. It begins with a detailed questionnaire covering your medical history, family history, lifestyle, alcohol intake and any previous operations or hospital admissions. Answer honestly and completely. Concealing information rarely ends well, and a declared, well-managed condition is far easier to certify than an undeclared one discovered later.

The examiner then records your height, weight and body mass index, and for a Class 1 may also measure your waist. Blood pressure is taken after you've been sitting quietly for a few minutes. A urine sample is dipped to check for glucose, protein and blood — a simple screen that occasionally flags something worth investigating. For an initial Class 1, expect blood tests covering cholesterol, blood glucose and haemoglobin, plus a resting ECG.

Eyes, Ears and the Senses That Matter

Vision testing goes well beyond reading a wall chart. You'll have distance acuity checked in each eye separately, with and without correction, along with near vision. Colour vision is assessed using plate tests or, where a deficiency is suspected, a more specialised lantern or computer-based test. Your visual fields and eye movements may also be checked. If you need glasses to meet the standard, that will be noted on your certificate as a limitation.

Hearing is measured by pure-tone audiometry for a Class 1, while a whispered voice test may suffice for a Class 2. Your ears, nose and throat are examined, and your balance and speech are noted. Bring hearing aids if you use them — the standards allow for them in some circumstances.

Heart, Lungs and General Physical Checks

The examiner listens to your heart and lungs, palpates your abdomen, and checks your peripheral pulses. Your nervous system is screened through reflexes, coordination and sensation testing, and your spine and joints are assessed for range of movement — relevant to control inputs and to sitting for long periods. For a Class 1, an ECG is repeated at set age milestones and may be supplemented by a treadmill exercise test as you get older.

If anything requires a second opinion, the examiner will refer you to a specialist or to the medical department of the UK's aviation regulator for review. This isn't a rejection; it's a request for more information, and a well-documented referral usually resolves within a few weeks.

Results, Certificate and What Happens Next

In the majority of cases where everything meets the standard, your certificate is issued at the end of the appointment or shortly afterwards. It may carry a limitation or endorsement — for example, requiring corrective lenses, a safety pilot, or a shorter validity period. Read it carefully and note the expiry date.

If further investigation is needed, you'll be told exactly what's required and how to submit it. Keep copies of everything you send. Above all, don't let paperwork drift: many pilots lose flying time not because of a medical condition, but because a renewal form sat unsigned on a desk. Book early, prepare thoroughly, and the examination becomes a routine box ticked rather than an obstacle to your next flight.
