The FAA lists 15 medical conditions as specifically disqualifying for pilot certification, ranging from heart disease to epilepsy to substance dependence. But “disqualifying” doesn’t always mean permanent. Many of these conditions can be addressed through a special issuance process, essentially a medical waiver, that lets pilots fly with periodic monitoring. Understanding which conditions fall on this list, and which ones can be worked around, is the key to knowing where you stand.
The 15 Specifically Disqualifying Conditions
Federal aviation regulations under 14 CFR Part 67 name these conditions as disqualifying for all classes of medical certificate:
- Angina pectoris (chest pain from reduced blood flow to the heart)
- Coronary heart disease that has been treated, or if untreated, has been symptomatic or clinically significant
- Myocardial infarction (heart attack)
- Cardiac valve replacement
- Permanent cardiac pacemaker
- Heart replacement
- Bipolar disorder
- Psychosis
- Epilepsy
- Diabetes mellitus requiring hypoglycemic medications (including insulin)
- Substance abuse
- Substance dependence
- Disturbance of consciousness without satisfactory explanation of cause
- Transient loss of control of nervous system function(s) without satisfactory explanation of cause
- Personality disorder severe enough to have repeatedly manifested itself by overt acts
Notice that the last two neurological conditions include the qualifier “without satisfactory explanation of cause.” If you fainted because of dehydration and your doctor can document exactly why it happened, that’s very different from an unexplained blackout. The FAA cares most about unpredictability, conditions where sudden incapacitation in the cockpit could endanger everyone on board.
Heart Conditions and Blood Pressure
Cardiovascular problems make up nearly half the specifically disqualifying list. The FAA treats the heart as the single biggest risk factor for sudden incapacitation, so the scrutiny here is intense. Any history of a heart attack, coronary artery disease that required treatment, valve replacement, pacemaker implantation, or heart transplant triggers an automatic denial or deferral by the examining physician.
Blood pressure doesn’t have a hard cutoff written into the regulations, but the FAA’s current guideline maximum is 155/95. If your readings consistently run above that, you’ll need to get it under control before certification. Heart rate alone isn’t disqualifying either. It’s used as one indicator of overall cardiac health during your exam. Pilots with a history of cardiac events can pursue a special issuance, but the documentation requirements are substantial, and ongoing monitoring is the norm.
Mental Health and Psychiatric Medications
This is the area that trips up more applicants than almost any other. Bipolar disorder and psychosis are specifically disqualifying. But beyond those two diagnoses, the FAA’s medication policy creates a much wider net: the use of any psychotropic drug is disqualifying for medical certification purposes. That includes all sedatives, tranquilizers, antipsychotic drugs, antidepressants (including SSRIs), anti-anxiety medications, and stimulants.
There are limited exceptions. The FAA has a pathway that allows certain SSRIs for pilots with depression or anxiety, but it involves a structured evaluation, waiting periods, and cognitive testing to demonstrate you can safely perform flight duties while on the medication. The process is not fast, and not every antidepressant qualifies. If you’re currently taking a psychiatric medication or have in the past, expect the FAA to want detailed treatment records before making a decision.
A history of situational depression or an adjustment disorder with depressed mood is handled differently from major depressive disorder or PTSD. The FAA has separate evaluation pathways depending on the diagnosis, its severity, and how recently you were treated. The key factor is whether the condition and its treatment are stable enough that cognitive function in the cockpit won’t be compromised.
ADHD and Stimulant Medications
A history of ADHD or past use of stimulant medications like Adderall or Ritalin doesn’t automatically end your chances, but it does require extra steps. The FAA considers both the condition itself and the medications used to treat it as potential risks to aviation safety because of the cognitive effects involved.
As of late 2024, there are two evaluation paths: a Fast Track and a Standard Track. The Fast Track is for straightforward cases, while the Standard Track involves more extensive neuropsychological testing. Both require documentation of your history, including when you were diagnosed, what medications you took, and when you stopped. If you’re currently taking ADHD medication, you will not be issued a medical certificate. You need to be off the medication and demonstrate stable cognitive function before the FAA will consider certification.
Diabetes and Insulin Use
Diabetes that requires medication to lower blood sugar is on the specifically disqualifying list. For years, insulin-dependent pilots were grounded entirely. That’s no longer the case, but the path to certification is demanding.
Pilots with Type 1 or Type 2 diabetes who use insulin can now apply for a special issuance, provided they’ve been clinically stable on their current treatment for at least six months. For first- and second-class certificates (commercial and airline transport pilots), the FAA requires continuous glucose monitoring data as part of the application. Third-class applicants (private pilots) can choose between the continuous monitoring protocol or an alternative monitoring approach. If certified, you’ll need to submit regular glucose data and medical reports on an ongoing basis to keep your certificate active.
Vision and Color Blindness
Vision problems aren’t on the specifically disqualifying list, but they can still prevent certification if you don’t meet the standards. The requirements vary by certificate class. First-class applicants (airline transport) face the strictest thresholds for both distance and near vision, while third-class (private pilot) standards are more forgiving. Corrective lenses are fine; your certificate will simply carry a limitation noting that you must wear them while flying.
Color vision is where things get more nuanced. You need to reliably distinguish aviation signal colors (red, green, and white) to identify runway lights, light gun signals, and chart symbology. As of January 2025, the FAA requires color vision testing to be done using approved computer-based tests administered in person. Printed plate tests like the old Ishihara books are being phased out. The approved computerized tests include the Colour Assessment and Diagnosis (CAD) test, the Rabin Cone Test, and the Waggoner Computerized Color Vision Test, each with specific passing scores. If you fail the screening version, a more detailed diagnostic test follows to determine the type and severity of your deficiency. Mild color vision deficiencies can still pass. Complete inability to distinguish red from green is a different story, though even then, a practical flight test demonstrating you can identify signals may be an option.
The Three Classes of Medical Certificate
Not every pilot needs to meet the same standards. The FAA issues three classes of medical certificate, each tied to the type of flying you want to do:
- First-class: required for airline transport pilots. The most rigorous standards, the most frequent renewal exams.
- Second-class: required for commercial pilots, flight engineers, and (as of May 2023) commercial balloon pilots. Slightly less stringent than first-class.
- Third-class: required for private and recreational pilots. The most lenient standards.
The 15 specifically disqualifying conditions apply to all three classes. Where the classes differ is in areas like vision thresholds, exam frequency, and how closely certain conditions are monitored. A condition that makes a first-class certificate impossible might still allow a third-class, depending on the specifics.
It’s also worth knowing that BasicMed, an alternative to the traditional FAA medical certificate, exists for certain private pilots. It involves working with your personal physician rather than an FAA-designated examiner, and it allows some conditions that would complicate the standard certification process. BasicMed has its own limitations on the type of flying you can do, but for recreational pilots with borderline medical issues, it’s a practical alternative.
The Special Issuance (Waiver) Process
A “specifically disqualifying” condition does not necessarily mean you’ll never fly. The Federal Air Surgeon has the authority to grant what’s called an Authorization for Special Issuance, a medical certificate given to someone who doesn’t meet the standard criteria but can demonstrate they can fly safely.
The process works like this: your FAA-designated medical examiner defers your application rather than issuing a certificate on the spot. Your medical records go to the FAA’s Aerospace Medical Certification Division for review. You’ll need to provide documentation from your treating physicians showing your condition is well-controlled, stable, and unlikely to cause sudden incapacitation. In some cases, the FAA may require a special medical flight test or practical evaluation.
If granted, a special issuance certificate comes with a defined validity period and conditions. You’ll typically need to submit updated medical reports at each renewal. The initial authorization always comes from an FAA physician, but subsequent renewals can often be handled by your regular aviation medical examiner through a streamlined process called AME Assisted Special Issuance (AASI). As of May 2023, if your AASI renewal is processed correctly and your condition hasn’t changed, the FAA no longer sends a separate confirmation letter; your authorization simply continues.
The timeline varies widely. Simple cases may take a few weeks. Complex cases involving multiple conditions or incomplete records can stretch to months. Having thorough, well-organized medical documentation from the start is the single biggest factor in speeding things up.
