Sleep Apnea in Pilots: EASA and FAA Medical Certification Guide 2026
How European aviation regulators screen, certify, and monitor pilots with obstructive sleep apnea, with a brief comparison to FAA practice for global crew.
Sleep apnea in pilots is a regulated condition under EASA Part-MED rules across Europe. Pilots in EU member states are screened at every annual medical revalidation and during initial Class 1, Class 2, or LAPL examination. A diagnosis of obstructive sleep apnea (OSA) does not automatically end a flying career, but undisclosed disease will. Read our primer on sleep apnea warning signs if you suspect OSA before your next medical.
This guide explains what the EASA Aero-Medical Examiner (AME) checks during a Class 1, Class 2, or LAPL exam, how the EASA Part-MED pathway works for pilots with diagnosed OSA, what national differences apply between EU member states, and how the FAA equivalent system compares for international crew. EASA Part-MED.A.045 frames OSA as a limiting condition that requires treatment effectiveness and documented compliance, not automatic revocation.
- EASA Part-MED is the binding rule for EU pilots; FAA is reference only.
- OSA disclosure is mandatory and protects the pilot.
- Effective treatment with documented compliance allows return to flying.
- National AeMCs hold final certification authority.
EASA medical certificate classes and OSA
EASA Part-MED, defined in Commission Regulation (EU) No 1178/2011 and updated in Regulation (EU) 2019/27, sets out three medical certificate classes. Each carries a distinct OSA threshold and revalidation schedule.
Class 1
Commercial pilots (CPL, ATPL, MPL). Annual revalidation under age 60, six-monthly above 60. Strictest OSA scrutiny because of multi-crew operations and passenger safety. Issued by Aero-Medical Centres (AeMC) only.
Class 2
Private pilots (PPL). Five-year revalidation under 40, two-year between 40 and 50, annual above 50. OSA assessed individually by AME but with more flexibility. Issued by AeMCs and AME.
LAPL
Light aircraft pilot licence. Five-year revalidation under 40, two-year above 40. Lighter screening burden, but OSA disclosure remains mandatory. Issued by general practitioners certified as AeMCs in some member states.
The EASA OSA screening question set
EASA AME Guidance Material requires AMEs to evaluate every pilot for sleep apnea risk through a structured questionnaire. Common screening tools used across EU member states include:
- Epworth Sleepiness Scale (ESS): score above 10 or 11 triggers further investigation.
- STOP-BANG questionnaire for high-risk identification.
- Body mass index (BMI), neck circumference, waist-to-hip ratio.
- Witnessed apnea or loud snoring history.
- Treatment history for hypertension or atrial fibrillation.
The EASA Part-MED pathway for OSA
When an AME identifies OSA risk, the certification process splits into four steps. EASA Part-MED.B.060 governs the assessment, with national civil aviation authorities applying additional procedural rules.
| EASA pathway step | What triggers it | What the pilot must do |
|---|---|---|
| 1. AME initial assessment | Epworth above 10, BMI above 30, witnessed apnea | Complete full questionnaire and physical exam |
| 2. Sleep study referral | Two or more risk factors at AME exam | Polysomnography or polygraphy in EU sleep centre |
| 3. National AeMC review | Confirmed OSA with AHI 5 or above | Submit study report and treatment plan |
| 4. Aero-medical decision | AeMC review complete | Provide compliance data over 30 to 90 days |
What documentation EASA wants
- Diagnostic sleep study (in-lab polysomnography or accepted home sleep test) reporting AHI, oxygen desaturation index, REM-related events.
- Treatment plan from a sleep medicine specialist, signed.
- Compliance download from CPAP machine or mandibular advancement device for 30 to 90 days.
- Follow-up polysomnography or polygraphy showing on-treatment AHI below 5.
- Cardiovascular and ENT clearance if indicated by AeMC review.
How long does EASA decision take?
For straightforward AeMC reviews, EASA decisions typically arrive within 4 to 12 weeks of full document submission. National civil aviation authorities can issue temporary medical certificates while reviews continue, allowing the pilot to maintain currency. Severity factors such as AHI above 30, residual daytime sleepiness, or cardiovascular comorbidity slow the process.
National differences inside Europe
EASA sets the minimum standard but member states retain operational authority. Differences worth knowing if you transfer your medical certificate inside the EU:
France (DGAC, CEMPN)
Centres d'Expertise Médicale du Personnel Navigant (CEMPN) handle Class 1 reviews. France allows partial-overnight polygraphy in selected cases. Compliance data accepted from EU-CE certified devices only.
Germany (LBA, AeMC)
Luftfahrt-Bundesamt and accredited AeMCs apply EASA Part-MED with extra cardiovascular screening. CPAP compliance must come from manufacturer-validated software downloads.
UK (CAA, post-Brexit)
The UK CAA mirrors EASA Part-MED in substance but operates as a third-country authority since 2021. UK Class 1 holders must verify mutual recognition before flying for an EU operator.
Italy (ENAC)
ENAC follows EASA Part-MED through Centri Aero-Medici. Italy generally requires in-lab polysomnography for Class 1 OSA assessment rather than home sleep studies.
Spain (AESA)
Agencia Estatal de Seguridad Aérea applies EASA rules through Centros Médicos Aeronáuticos. Spain has historically allowed shorter compliance windows (30 days) for return to flying.
Netherlands (ILT, IL&T)
The Inspectie Leefomgeving en Transport coordinates with EASA-recognised AeMCs. The Dutch system has digital portals for compliance data submission.
How FAA differs from EASA (for international crew)
For pilots who fly under both EU and US-issued certificates, the regulatory comparison matters. EASA leads for European pilots; FAA rules apply only when flying under an FAA certificate. Key differences are operational, not philosophical, since both bodies share the same scientific evidence base.
| Topic | EASA Part-MED | FAA equivalent (reference only) |
|---|---|---|
| OSA framework | Limiting condition under Part-MED.A.045 | Pathways A to D under AME Guide |
| Decision authority | National AeMC + civil aviation authority | FAA Aerospace Medical Certification Division |
| Certificate suspension default | Individualised assessment, often non-suspending | Suspension until Special Issuance granted |
| Compliance window | 30 to 90 days CPAP download | 30 to 90 days CPAP download |
| Oral appliance acceptance | Yes for mild to moderate OSA with documented control | Yes for mild to moderate OSA |
| Re-issue speed | 4 to 12 weeks typical | 30 to 90 days typical |
Treatment options that maintain certification
EASA accepts several treatment routes. The choice depends on OSA severity, anatomy, and adherence. Read the broader review of CPAP alternatives for the wider context.
| Treatment | OSA severity | EASA accepted | Adherence proof |
|---|---|---|---|
| CPAP / APAP | Moderate to severe | Yes (gold standard) | Device download |
| Mandibular advancement device | Mild to moderate | Yes with post-treatment study | Worn-time sensor + sleep study |
| Hypoglossal nerve stimulation (Inspire EU, Genio) | Moderate to severe selected cases | Yes after appropriate work-up | Device download + study |
| Positional therapy device | Mild positional OSA | Case-by-case | Sleep study, sensor logs |
| Weight loss + lifestyle | Adjunct in mild cases | Adjunct only | Repeat polysomnography |
| Intranasal stent (Back2Sleep) | Snoring + selected mild OSA | Adjunct, not primary OSA treatment | Repeat polygraphy |
Step-by-step from screening to medical issuance
Use this checklist when preparing your next EASA Class 1 or Class 2 medical and you suspect or have OSA.
- Self-screen. Complete the Epworth and STOP-BANG questionnaires honestly.
- Pre-emptive sleep study. Arrange a polysomnography or polygraphy through your GP (médecin traitant, Hausarzt, etc.) if any score flags risk. EU public systems usually cover the test.
- Disclose to AME. Bring the report and a draft treatment plan to your AME consultation.
- Begin treatment. CPAP is fastest to titrate; oral appliance fitting takes a few weeks.
- Collect compliance. Maintain a 30 to 90 day adherence log from the device download.
- Repeat sleep study. Polysomnography or polygraphy on treatment, demonstrating AHI under 5.
- Submit to AeMC. The AME forwards the full package to the national Aero-Medical Centre or directly to the civil aviation authority.
- Follow-up plan. Annual download review and yearly questionnaire at every revalidation.
In-cockpit fatigue rules
EASA Flight Time Limitations under Regulation (EU) 83/2014 regulate duty periods, rest minima, and fatigue risk management systems for commercial operators. National authorities can issue stricter local rules. Pilots with OSA must comply with both: the medical fitness rule and the FTL.
Practical tips for OSA-positive pilots
- Carry your CPAP machine in carry-on luggage; airline guidelines typically accept medical devices.
- Use a portable battery for layovers without reliable power.
- Travel-friendly nasal stents like Back2Sleep can complement CPAP on short stops with no power.
- Keep a digital copy of your AME report for transfer between operators.
- Schedule annual revalidations early in the cycle to allow time for adherence reviews.
Long-term monitoring after issuance
OSA is a chronic condition. EASA expects ongoing monitoring even when the pilot is well controlled.
- Submit CPAP or oral appliance compliance download with each medical revalidation.
- Repeat the Epworth Sleepiness Scale.
- Update weight, BMI, and neck circumference.
- Repeat polysomnography or polygraphy every 3 to 5 years or with symptom change.
- Note any new cardiovascular events and disclose immediately.

Frequently asked questions
Does sleep apnea automatically ground a pilot under EASA rules?
No. Obstructive sleep apnea is a 'limiting condition' under EASA Part-MED.A.045, not an automatic disqualification. Pilots with diagnosed OSA can keep their Class 1, Class 2, or LAPL medical if treatment is effective and adherence documented. Concealing the diagnosis, however, is grounds for revocation.
What is the EASA AME screening process for OSA?
The Aero-Medical Examiner (AME) uses the Epworth Sleepiness Scale, neck circumference, BMI, and witnessed apnea questions at every annual medical revalidation. A score of 11 or above on the Epworth scale triggers further investigation. The AME may defer fitness pending a sleep study.
How long does EASA medical recertification take after OSA diagnosis?
Recertification typically takes 4 to 12 weeks after OSA diagnosis. The pilot must complete a sleep study, start treatment, and document adherence for 30 to 90 days. The decision rests with the national aero-medical authority (AeMC) which forwards the case to the EASA-recognised authority of issue.
What CPAP usage does EASA require for pilots?
EASA expects documented CPAP use of at least four hours per night on 70 percent of nights, with download data from the device for the prior 30 to 90 days. Many EU airlines provide hotel power adapters for crew members travelling internationally.
Are oral appliances accepted by EASA for pilots?
Yes. EASA accepts mandibular advancement devices for mild to moderate OSA when fitted by a qualified dentist with documented post-treatment polysomnography or polygraphy showing adequate AHI control. Adherence is harder to monitor objectively than with CPAP, so AeMCs may request follow-up sleep studies.
How does EASA treat sleep apnea differently from FAA?
EASA emphasises individualised assessment by the national AeMC under Part-MED.B.060, while the FAA uses standardised AME pathways A through D. EASA does not require an automatic Special Issuance equivalent and tends to allow earlier return to flying once treatment is documented. National differences exist between member states.
How is fatigue regulated for pilots in Europe?
EASA Flight Time Limitations (FTL) under Regulation (EU) 83/2014 limit flight duty periods, mandate minimum rest, and require fatigue risk management systems. Sleep apnea and chronic fatigue are part of the medical fitness assessment. National civil aviation authorities enforce additional rules.
Can I use the Back2Sleep nasal stent as a pilot?
The Back2Sleep nasal stent is a CE-certified Class I device for snoring and mild to moderate OSA. It is not a substitute for CPAP in moderate to severe OSA cases under EASA review, but may help selected mild cases when post-treatment polygraphy confirms adequate AHI control. Always discuss with your AME first.
