FAA Medical Flight Test (MFT): What Pilots Need to Know

If you've received a letter from the FAA's Aerospace Medical Certification Division (AMCD) telling you that a Medical Flight Test is required before your medical certificate can be issued, you're probably feeling a mixture of confusion, frustration, and anxiety. Take a breath. This is not the end of your flying career — in fact, it's often a well-defined path toward getting your medical certificate with a permanent authorization that never expires.

As an AME who regularly guides pilots through this process, I want to walk you through exactly what a Medical Flight Test is, who needs one, how to schedule it, and how to give yourself the best chance of success.

What Is a Medical Flight Test (MFT)?

A Medical Flight Test — sometimes called a Special Medical Flight Test or SMFT — is a practical, in-the-airplane evaluation required by the FAA for pilots who don't meet one or more standard medical requirements but may still be able to safely operate an aircraft despite a physical condition. The legal authority for this comes from 14 CFR Part 67, Section 67.401.

Think of it this way: the FAA's written medical standards are binary — you either meet them or you don't. But flying is a practical skill, and many physical conditions that technically fail the written standards don't actually impair a pilot's ability to fly safely. The MFT is the FAA's way of letting you prove that in the cockpit.

The conditions that most commonly require an MFT include:

• Vision conditions: Monocular vision (functional use of only one eye), significant strabismus (eye misalignment), Duane's Syndrome, visual field defects, or defective color vision
• Limb differences: Upper or lower limb amputations, prostheses, or significant loss of function
• Hearing impairment: Speech or hearing deficiencies that may affect radio communication

If your condition is static and non-progressive — meaning it's not going to get worse over time — the MFT pathway is particularly favorable because a successful test typically results in a permanent authorization.

The Letter You Received: What It Means

When the FAA determines an MFT is needed, you'll receive correspondence from the Aerospace Medical Certification Division (AMCD, AAM-300) in Oklahoma City. This is typically what happens in sequence:

1. Your AME defers or denies your application — This is standard procedure and does not mean you've been permanently denied. Your AME notes the condition and your desire for an MFT authorization.
2. AMCD reviews your case — They evaluate the medical documentation you've submitted (ophthalmology reports, Form 8500-7, etc.).
3. You receive a Letter of Authorization (LOA) — This is the critical document. It authorizes a specific FAA inspector to conduct your MFT, outlines exactly what will be tested, and is sent to the FSDO (Flight Standards District Office) you've designated. A copy comes to you.

For pilots with vision conditions like Duane's Syndrome, the LOA will typically specify evaluation of depth perception compensation, peripheral awareness, and your ability to identify terrain features, traffic, and airport elements despite the visual limitation.

Understanding the Key Players

AMCD (Aerospace Medical Certification Division)

Located in Oklahoma City, AMCD is the central FAA office that makes medical certification decisions. They review your medical records, issue the Letter of Authorization for the MFT, and ultimately issue your medical certificate and SODA after you pass. All MFT authorizations must come from AMCD (AAM-300) or the Federal Air Surgeon.

Your Local FSDO (Flight Standards District Office)

The FSDO is where your MFT will actually be scheduled and conducted. FSDOs handle airman certification, and they have Aviation Safety Inspectors (ASIs) who are specifically trained to conduct MFTs. When your LOA arrives at the FSDO, an inspector will be assigned to your test.

You can find your nearest FSDO using the FAA's FSDO locator page. If you're an airline pilot or operate under Part 121 or 135, you may need to coordinate with a Certificate Management Office (CMO) instead.

The Aviation Safety Inspector (ASI)

Your MFT is not conducted by a regular Designated Pilot Examiner (DPE). It must be conducted by an FAA Aviation Safety Inspector who has received your Letter of Authorization. This is an important distinction — the ASI has specific training in evaluating pilots with physical conditions and will follow the evaluation criteria outlined in your LOA.

How to Schedule Your MFT

Once your Letter of Authorization has been sent to the FSDO, here's how to move forward:

1. Contact the FSDO directly. Call or visit the office listed on your LOA. Ask to speak with the inspector assigned to your MFT, or ask the front desk to connect you with the ASI who handles medical flight tests.
2. Confirm they have your LOA. Sometimes paperwork takes a few weeks to arrive. If they haven't received it, contact AMCD to verify it was sent and to which office.
3. Discuss logistics. The inspector will want to know what type of aircraft you'll be using, which airport you'd like to fly from, and your availability. Be flexible — inspectors have busy schedules.
4. Ask what to expect. This is completely appropriate and encouraged. The inspector can walk you through the specific test items listed on your LOA so you can prepare properly.

When to Contact a Certificate Management Office (CMO)

If you hold an Airline Transport Pilot (ATP) certificate and fly for an air carrier operating under FAR Part 121 or 135, your certification oversight may fall under a Certificate Management Office (CMO) rather than a FSDO. CMOs oversee specific airlines and air carriers, so if you're a professional airline pilot, check whether your carrier's CMO should be involved in the MFT coordination. Your airline's chief pilot or aviation medical department can help clarify this.

Can You Combine the MFT with a Checkride?

Yes. If you're a student pilot who hasn't yet earned your certificate, the FAA allows you to combine the Medical Flight Test with your practical test (checkride) for a pilot certificate or rating. This is efficient and saves time. The key requirements are:

• You must meet the flight experience requirements for the certificate you're seeking
• You need to be at least at solo proficiency level
• The request to combine tests should be coordinated in advance with both the inspector and your CFI

An important note: if you combine the tests, it's possible to pass the medical portion but fail the practical portion (or vice versa). They're evaluated independently. If you pass the medical flight test but fail the checkride, you can retest the practical portion with a DPE later without repeating the medical demonstration.

What Happens During the MFT

The specific test items depend entirely on your condition and what's written in your Letter of Authorization. However, here are some common elements by condition type:

Vision-Related MFTs (Monocular Vision, Duane's Syndrome, Strabismus)

The inspector will evaluate your ability to:

• Judge distances and depth during approach and landing
• Identify terrain features, obstacles, and emergency landing areas
• Spot traffic and maintain situational awareness in the pattern
• Read airport signage, markings, and identify runway configurations
• Demonstrate safe operations that compensate for any visual limitation

Color Vision MFTs

For first and second class applicants, you'll need to pass both:

• Operational Color Vision Test (OCVT): Identify colors on aeronautical charts and demonstrate ability to read airport lighting and signage
• Signal Light Test (SLT): Correctly identify red, green, and white light gun signals from the control tower

Third class applicants typically only need the OCVT portion.

Hearing Impairment MFTs

The LOA will specify whether testing is in an open or closed cockpit environment. You'll need to demonstrate that you can:

• Communicate effectively with ATC (or operate safely without radio if seeking a limitation)
• Hear engine sounds and warning indicators
• Maintain safe operations with your level of hearing ability

Limb Difference MFTs

If you have a limb amputation, prosthesis, or functional limitation, the inspector will evaluate your ability to:

• Manipulate all required flight controls throughout the full range of motion
• Perform normal and emergency procedures
• Manage the aircraft on the ground (taxiing, braking)

How to Prepare for Success

Based on years of guiding pilots through this process, here are my top recommendations:

1. Get Your Documentation Right — Before Everything Else

For vision conditions, have your ophthalmologist complete FAA Form 8500-7 (Report of Eye Evaluation) thoroughly. The form should clearly document:

• Your exact diagnosis
• Best corrected visual acuity in each eye and both eyes together
• That the condition is static and non-progressive (if applicable)
• Any relevant history (absence of diplopia, length of time with condition, etc.)

For other conditions, gather all relevant specialist reports, surgical records, and documentation of stability.

2. Be Proficient — Not Just Minimally Competent

You need to be at least at solo proficiency, but I'd recommend being well beyond that. The MFT isn't a time to be shaky on basics. The inspector is evaluating whether your physical condition creates a safety concern — don't give them reason to wonder if a mistake is due to your condition or just poor technique.

3. Talk to the Inspector Before the Test

This is completely appropriate and encouraged. Call the ASI who will be conducting your test, introduce yourself, and ask what specific items they'll be evaluating. The FAA wants pilots to succeed in this process — they're not trying to trick you. Understanding the test items in advance helps you prepare effectively.

4. Fly the Aircraft You're Most Comfortable In

Unless there's a specific requirement otherwise, use the aircraft you've been training in and are most familiar with. This is not the time to borrow a friend's Bonanza if you've been training in a Cessna 172.

5. Brief Your CFI or Safety Pilot

If you're bringing a CFI or safety pilot along, make sure they understand the process and won't interfere. The inspector needs to observe your abilities, not your instructor's coaching.

6. Don't Rush the Timeline

The FAA process takes time — typically 4 to 12 weeks from your initial application deferral to receiving the LOA. Use that time productively to continue building flight hours and proficiency. There's no advantage to scheduling the MFT before you're truly ready.

What Happens If You Pass

If you successfully complete the MFT, the inspector sends the results back to AMCD. You will then receive:

• A Medical Certificate — issued under 14 CFR 67.401, which is the special issuance provision
• A Statement of Demonstrated Ability (SODA) — this is the key document. For static, non-progressive conditions, the SODA never expires. As long as your condition hasn't worsened, your AME can issue subsequent medical certificates without you needing to repeat the MFT.

Your certificate and/or pilot certificate may include operating limitations based on the inspector's findings. Common examples include:

• "Not valid for flights requiring the use of radio" (hearing/speech conditions)
• "Limited to daytime flight only" (certain color vision limitations)
• Aircraft-specific limitations for limb conditions

These limitations are not punitive — they're practical safety measures that allow you to fly within the bounds of what you've demonstrated you can do safely.

What If You Don't Pass

If the inspector determines that your condition does create a safety concern during the flight, the test will be terminated. This doesn't necessarily mean the door is permanently closed. Options may include:

• Additional training to develop better compensatory techniques
• Adaptive equipment or modifications to the aircraft
• A different aircraft type that may be more suitable
• Reconsideration after addressing the specific deficiency identified

In some cases, you may also have the right to request reconsideration from the Federal Air Surgeon or pursue further review through the NTSB within specific timeframes.

A Note on Timelines and Patience

The MFT process tests your patience almost as much as your flying ability. Here's a realistic timeline:

• Weeks 1-2: Gather medical documentation (Form 8500-7, specialist reports)
• Week 3: AME visit — application is deferred to AMCD
• Weeks 4-12: AMCD review and LOA issuance
• Weeks 12-16: Schedule and complete MFT at your FSDO
• Weeks 16-20: Receive medical certificate and SODA from AMCD

The total process can take 3 to 5 months from start to finish. This is normal. Use the time wisely — keep flying with your CFI, build proficiency, and stay current on your medical documentation.

The Bottom Line

A Medical Flight Test requirement is not a rejection — it's an opportunity. Thousands of pilots with vision conditions, limb differences, hearing impairment, and other physical conditions have successfully completed MFTs and gone on to long, safe flying careers. The process is well-established, the inspectors are professional, and the outcome — a permanent SODA that never expires — is one of the best possible results in the FAA medical certification system.
