A Class 1 medical certificate is the highest level of FAA medical clearance, required for anyone flying as an airline transport pilot or serving as a required crew member on airline flights. It involves a comprehensive physical exam covering vision, hearing, heart health, blood pressure, mental health, and neurological function. If you’re planning a career in the airlines, this is the medical certificate you’ll need to earn and maintain throughout your career.
Who Needs a Class 1 Medical
Federal aviation regulations specify three situations that require a first-class medical certificate. You need one when exercising pilot-in-command privileges under an airline transport pilot (ATP) certificate, when serving as second-in-command on certain airline operations that require three or more pilots, and when serving as a required crew member on Part 121 airline operations after your 60th birthday.
In practical terms, this means airline captains and first officers at commercial carriers. If you’re flying privately or working as a flight instructor, a lower-class medical (second or third) will suffice. But if your goal is the flight deck of a regional or major airline, a Class 1 is non-negotiable.
How Long It Stays Valid
Your age determines how often you’ll need to renew. If you’re under 40 on the date of your exam, a first-class medical certificate is valid for 12 calendar months (plus the remainder of the month it was issued). Once you turn 40, that window shrinks to 6 calendar months. After a first-class certificate expires, it doesn’t disappear entirely. It “downgrades” and can still function as a second- or third-class certificate for a longer period, but you can no longer use it for airline operations.
This means pilots over 40 who fly for airlines are visiting an aviation medical examiner (AME) twice a year.
What the Exam Covers
The exam is thorough but not dramatically different from a detailed annual physical, with a few aviation-specific additions. Here’s what to expect.
Vision
You’ll be tested for distance, near, and intermediate visual acuity. Corrective lenses are allowed, so wearing glasses or contacts won’t disqualify you. Color vision is also tested, and as of January 2025, the FAA requires approved computer-based screening tests for first-time applicants. If you fail every available color vision test, you’ll only be issued a third-class certificate with a restriction limiting you to daytime visual flight rules. Upgrading from there requires an appeal to the Federal Air Surgeon. If you’ve previously passed a color vision test, you won’t need to repeat the computer-based screening.
Hearing
The simplest hearing test is a conversational voice test, where you need to understand speech at a set distance. If you can’t pass that, two alternatives exist: a speech discrimination test requiring a score of at least 70%, or a pure-tone audiometry test using headphones. The audiometry standards allow up to 35 decibels of hearing loss at 500 Hz, 30 dB at 1,000 and 2,000 Hz, and 40 dB at 3,000 Hz in your better ear. The thresholds are more generous for the poorer ear.
Blood Pressure
Your blood pressure must not exceed 155/95 mmHg. If you’re managing hypertension with medication, the FAA may still certify you, but you’ll need to have been off antihypertensive medication for at least 30 days to be issued a certificate on the spot by the examiner. Pilots on approved blood pressure medications can still qualify through additional review.
Heart Health
This is where the Class 1 exam diverges most from lower classes. An electrocardiogram (EKG) is required at your first exam after turning 35, serving as a baseline. From age 40 onward, an EKG is required annually. Second- and third-class certificates don’t require an EKG at any age, making this one of the key differences of the first-class exam.
Conditions That Can Ground You
Certain medical conditions are initially disqualifying for all classes, though many can eventually be certified through a waiver process. Conditions that trigger automatic deferral include coronary heart disease, atrial fibrillation, stroke or transient ischemic attack, heart valve replacement or repair, and mitral valve disease. Neurological conditions like neurofibromatosis and certain migraine headaches also fall into this category.
Mental health conditions, substance use disorders, and certain medications (particularly those affecting the central nervous system) can also be disqualifying. The FAA maintains detailed disposition tables that AMEs use to determine whether a condition can be addressed during the exam or must be referred to FAA headquarters for review.
The Special Issuance Process
A disqualifying condition doesn’t always mean the end of a flying career. The FAA offers two pathways for pilots who don’t meet standard medical criteria.
A Special Issuance authorization allows the Federal Air Surgeon to grant a medical certificate with a defined validity period to someone who can demonstrate they can safely perform pilot duties despite a disqualifying condition. This typically involves submitting detailed medical records, specialist evaluations, and sometimes completing a special medical flight test. The initial decision must come from an FAA physician. You cannot receive a first-time Special Issuance from your AME alone.
For subsequent renewals, the FAA has streamlined things through a program called AME Assisted Special Issuance (AASI). Once you’ve been granted an initial authorization, your AME can re-issue your certificate at future exams as long as you bring the required medical documentation specified in your authorization letter. This saves weeks of waiting for paperwork to travel through FAA offices.
A Statement of Demonstrated Ability (SODA) is the other pathway, used primarily for stable conditions like color vision deficiency or limb loss. It typically involves a practical demonstration that you can safely operate an aircraft despite the condition.
Cost and Scheduling
The FAA does not set fees for medical exams, so pricing varies by examiner and region. Most Class 1 exams fall in the $100 to $200 range, though some AMEs charge more. The exam itself typically takes 30 to 60 minutes.
You’ll need to find a designated Aviation Medical Examiner. Not every AME is authorized to perform Class 1 exams; some are only approved for second- and third-class certificates. Senior AMEs generally handle all three classes. The FAA maintains a searchable directory of examiners on its website. Before your appointment, you’ll need to fill out your application through the FAA’s MedXPress system online, which generates a confirmation number your AME will use during the exam.
Preparing for Your First Exam
If you’re applying for the first time, bring a list of all medications you take, any surgical history, and contact information for your treating physicians. Be honest on the application. Falsifying medical history on an FAA form is a federal offense, and the FAA cross-references records with other government databases. If you have a condition you’re unsure about, consider consulting with an aviation medical advocacy organization before your exam. They can review your records and advise you on whether to expect complications, which is far better than being surprised with a deferral at the AME’s office.
For pilots with well-controlled conditions like high blood pressure, mild sleep apnea, or a history of depression, certification is often possible with proper documentation. The process may take longer, but the pathways exist.
