Update (May 2026): The FAA has replaced the separate initial and recertification status summaries described below with a single, simplified form. Read our follow-up article: The New FAA OSA Treated Status Report: Sleep Apnea Certification Just Got Simpler.
Obstructive Sleep Apnea (OSA) is one of the most common medical conditions affecting pilots and one that the FAA takes very seriously. The FAA considers untreated OSA a disqualifying condition because of its potential to cause excessive daytime sleepiness, cognitive impairment, cardiac problems, and sudden incapacitation — all of which pose obvious safety risks in the cockpit.
The good news: a diagnosis of OSA does not end your flying career. Thousands of pilots hold valid medical certificates while managing OSA with CPAP therapy, dental appliances, positional devices, or surgery. The key is understanding the FAA's protocol, meeting the compliance requirements, and working with an AME who knows the system.
This guide walks through the entire FAA OSA process — from how your AME screens you during a medical exam, through diagnosis and treatment, all the way to maintaining your certification long-term.
Important Note:
This article covers obstructive sleep apnea only. Other sleep disorders — central sleep apnea, narcolepsy, restless leg syndrome, insomnia, circadian rhythm disorders — have different FAA pathways and typically require direct review by the FAA's Aerospace Medical Certification Division (AMCD). If you have one of these conditions, contact your AME or reach out to us for guidance.
Why the FAA Cares About Sleep Apnea
Sleep apnea causes repeated interruptions in breathing during sleep, preventing the brain from reaching deep, restorative sleep stages. Over time, this produces a pattern of chronic sleep deprivation that pilots may not even recognize — often described as "getting used to being tired."
The FAA's concern is rooted in well-documented safety risks:
- Excessive daytime sleepiness (daytime hypersomnolence) — the most immediate flight safety concern
- Cognitive impairment — reduced attention, slower reaction times, impaired judgment and decision-making
- Cardiac dysrhythmia — including atrial fibrillation, which itself is a separate FAA concern
- Refractory hypertension — blood pressure that resists treatment, often linked to untreated OSA
- Personality disturbances — irritability, mood changes, depression
- Sudden cardiac death — in severe, untreated cases
The FAA's position is clear: OSA is disqualifying if untreated, but certification may be considered once effective treatment is demonstrated.
Who Is at Risk? The AME Screening Process
The FAA requires every Aviation Medical Examiner (AME) to screen for OSA risk at every medical exam. This is not optional — AMEs must evaluate each applicant and assign them to one of six groups based on their risk profile.
Risk factors the AME evaluates include:
| Risk Factor | Details |
|---|---|
| Body Mass Index (BMI) | Over 90% of individuals with BMI ≥ 40 have OSA requiring treatment. However, up to 30% of OSA patients have a BMI under 30 — BMI alone is not the sole indicator. |
| Neck circumference | Larger neck size correlates with higher OSA risk |
| Physical findings | Retrograde mandible, large tongue or tonsils, neuromuscular disorders, connective tissue anomalies |
| Associated conditions | Refractory hypertension (requiring > 2 medications), diabetes mellitus, atrial fibrillation |
| Symptoms | Reported snoring, witnessed apneas, daytime sleepiness, morning headaches, difficulty concentrating |
Key Point: The FAA has made clear that no airman should be disqualified based on BMI alone. The AME is expected to use clinical judgment along with the American Academy of Sleep Medicine (AASM) risk criteria when making triage decisions.
The 6-Group Triage System (AME Flow Chart)
At every FAA medical exam, the AME must assign each applicant to one of six groups. This triage determines whether you can be issued a certificate on the spot, need further evaluation, or must be deferred to the FAA. Understanding which group you fall into is the first step in navigating the process.
| Group | Description | AME Action |
|---|---|---|
| 1 | Has OSA diagnosis and is on Special Issuance | Follow AASI/SI requirements, document in Block 60, issue if otherwise qualified |
| 2 | Has prior sleep assessment or OSA diagnosis, NOT on Special Issuance | Provide AASI requirements, give Specification Sheet A, submit documentation to FAA |
| 3 | Not at risk for OSA at this examination | Document in Block 60, issue if otherwise qualified |
| 4 | Some risk factors present — low-to-moderate risk | Discuss OSA risk with pilot, provide educational materials, issue if otherwise qualified |
| 5 | At risk for OSA — assessment required | Issue certificate (not time-limited), pilot has 90 days to complete AASM sleep assessment |
| 6 | Extremely high risk — immediate safety concern | Deferred. AASM sleep assessment required before certification |
Good news for Group 5 pilots: If your AME puts you in Group 5, you are still issued your medical certificate that day (it is not time-limited). You then have 90 days to get a sleep assessment. The FAA tracks the 90-day window — you don't need to worry about a special expiration date on your certificate.
The flow chart below (from FAA.gov) illustrates this triage process visually:
FAA OSA Triage Flow Chart
START → AME Exam
At every exam, the AME uses AASM criteria, symptoms, and physical/clinical findings to triage the airman. No disqualification should be based on BMI alone.
PREVIOUSLY ASSESSED
Group 1: On Special Issuance → Follow AASI, issue
Group 2: Prior assessment, no SI → Submit docs to FAA
NOT AT RISK
Group 3: No risk factors → Document Block 60, issue
LOW/MOD RISK
Group 4: Educate, issue
AT RISK
Group 5: Issue, 90-day assessment window
EXTREME RISK
Group 6: Deferred until assessed

The Sleep Study: What to Expect
If you are placed in Group 5 or 6, or if your physician recommends a sleep assessment, you will need a formal sleep study. The FAA has specific requirements about what type of study is acceptable:
| Study Type | Description | FAA Acceptable? |
|---|---|---|
| Type I | Full polysomnogram (PSG) in a sleep lab — attended, comprehensive | Yes ✓ |
| Type II | Unattended home study with same monitoring sensors as Type I (7-channel) | Yes ✓ |
| Type III | Limited home study — measures cardiopulmonary parameters only | Conditional* |
| Type IV | Minimal — measures only 1-2 parameters (O2 sat, heart rate) | No ✗ |
*Type III may be accepted if a Level II HST is unavailable in the pilot's community. If positive for OSA, no further testing is needed. If equivocal, a higher-level study will be required unless a sleep medicine specialist documents rationale for no further testing.
Important: The sleep study must be interpreted by a board-certified sleep medicine specialist, even if the AME ordered or facilitated the study.
Treatment Options the FAA Accepts
Once OSA is diagnosed, the FAA recognizes several treatment approaches for medical certification. Each has its own documentation and compliance requirements:
1. PAP Therapy (CPAP / BiPAP / APAP)
Positive Airway Pressure therapy is the most common treatment pathway. The FAA's compliance targets for PAP are specific and higher than typical insurance requirements:
- Use for at least 75% of sleep periods
- Average minimum of 6 hours per sleep period
- Must provide a cumulative annual PAP device report showing actual hours used — not the abbreviated insurance report that only shows whether use exceeds 4 hours
- If your CPAP does not have recording capability, a one-year exception allows a personal statement of regular use
Common Pitfall: Many pilots submit the summary report generated for their insurance company, which typically only shows "compliant" or "non-compliant" based on a 4-hour threshold. The FAA requires the detailed cumulative report showing actual nightly usage hours. Ask your DME provider or access your CPAP's cloud portal (ResMed myAir, Philips DreamMapper, etc.) for the full data download.
2. Dental Devices (Oral Appliances)
Mandibular advancement devices are an alternative for pilots who cannot tolerate CPAP. Additional requirements apply:
- No conditions known to be co-morbid with OSA (diabetes, hypertension requiring > 2 medications, atrial fibrillation)
- Once dental devices with recording/monitoring capability become available, usage reports must be submitted
3. Positional Therapy
For pilots whose OSA is primarily positional (occurs only when sleeping supine), positional devices may be accepted with the same co-morbidity restrictions as dental devices.
4. Surgery
Surgical treatment (UPPP, MMA, hypoglossal nerve stimulation, etc.) requires a statement attesting to continued absence of OSA symptoms after the procedure. No ongoing device compliance data is needed, but a follow-up sleep study may be required.
The AASI: How Recertification Works
Once you receive your initial Special Issuance authorization for OSA, subsequent renewals use the AME Assisted Special Issuance (AASI) pathway. This means your AME can re-issue your certificate at the time of your exam — you do not need to wait for FAA headquarters to process paperwork — as long as you provide:
- Your FAA Authorization letter (the Special Issuance document)
- A signed Airman Compliance with Treatment Sheet — attesting that you are using your prescribed therapy and have no OSA symptoms (daytime sleepiness, lack of concentration, etc.)
- A current status report from your treating physician confirming treatment remains effective
- For PAP users: your cumulative annual device report showing actual usage data
The AME reviews these documents, confirms compliance, documents findings in Block 60, and issues your certificate. The process is designed to be straightforward once you have everything organized.
When the AME Must Defer to the FAA
There are situations where the AME cannot issue your certificate under AASI and must refer your case to the FAA's Aerospace Medical Certification Division (AMCD) or Regional Flight Surgeon (RFS):
- Concerns about adequacy of therapy or evidence of non-compliance
- Significant weight gain since last evaluation
- Development of conditions co-morbid with OSA — new diabetes, new atrial fibrillation, refractory hypertension
- Change in treatment modality not previously approved
On the positive side, if there are indications that you no longer have OSA (significant weight loss, surgical intervention followed by 3 years of symptom-free status), the AME can request AMCD review to discontinue the AASI entirely. In most cases, a follow-up sleep study will be required to confirm.
Common Screening Questionnaires
The FAA provides several screening tools that AMEs and pilots may encounter during the evaluation process:
- STOP-BANG Questionnaire — Snoring, Tiredness, Observed apneas, Pressure (blood pressure), BMI, Age, Neck circumference, Gender. One of the most widely used screening tools.
- Epworth Sleepiness Scale — Measures daytime sleepiness by asking how likely you are to doze off in various situations.
- Berlin Questionnaire — Evaluates snoring behavior, daytime sleepiness, and hypertension/BMI risk factors.
These questionnaires are tools to support clinical judgment — they do not replace the AME's overall assessment.
Frequently Asked Questions
Can I be grounded just because of a high BMI?
No. The FAA has been clear that no disqualification of airmen should be based on BMI alone. However, a very high BMI (≥ 40) combined with other risk factors will likely place you in Group 5 or 6, requiring a sleep assessment.
If I'm placed in Group 5, do I get a time-limited certificate?
No. The AME issues a regular (not time-limited) certificate. You have 90 days to complete your sleep assessment. The FAA tracks this timeline — there is no special expiration on your certificate.
Can I fly while waiting for my sleep study results?
If you were issued a certificate (Group 5), yes — you can fly with your current certificate. However, per 14 CFR 61.53, once you are diagnosed with OSA and begin treatment, you may return to flight duties once you are compliant with treatment and all required documentation has been submitted to the FAA.
What type of home sleep test does the FAA accept?
The FAA requires a Type I (in-lab polysomnogram) or Type II (7-channel home sleep test). A Type III may be accepted if Type II is unavailable locally. Type IV tests are not acceptable.
I had a sleep assessment years ago that was negative. Do I need a new one?
Not necessarily. If there has been no change in your risk factors, you fall under Group 2 — provide a copy of the previous assessment. However, if risk factors have changed (weight gain, new atrial fibrillation, new hypertension), the AME will re-triage you using the flow chart.
Can my OSA Special Issuance be removed if I no longer have sleep apnea?
Yes. If you've had significant weight loss, successful surgery, or other factors suggesting resolution, the AME can request AMCD review to discontinue the AASI. A follow-up sleep study is typically required to confirm the condition has resolved.

The Bottom Line
A diagnosis of obstructive sleep apnea is not the end of your flying career — far from it. The FAA has a well-defined, structured protocol that allows pilots with treated OSA to maintain their medical certificates. The keys to success are:
- Use your therapy consistently. The FAA's 75% / 6-hour CPAP standard is higher than insurance minimums — aim to exceed it.
- Keep detailed records. Download your full CPAP data report (not the insurance summary) before each medical exam.
- Stay ahead of your paperwork. Have your treating physician's status report, your compliance sheet, and your PAP data ready before your AME visit.
- Work with an AME who understands OSA. An experienced AME can ensure your documentation is complete and issue your certificate at the time of your exam under AASI.
