Sleep Apnea in Airline Cabin Crew and How EU Medical Fitness Rules Differ From Pilot Certification

What the sleep apnea cabin crew EASA medical rule actually requires

A sleep apnea cabin crew EASA medical turns on one short provision, and a diagnosis on its own does not ground you. AMC3 MED.C.025 (Respiratory System) lists "sleep apnoea syndrome/sleep disorder" among the conditions where a crew member must undergo a respiratory evaluation with a satisfactory result before a fit assessment may be considered.

That sentence is the whole trigger. It is written for aeromedical examiners rather than for crew, which is why flight-deck rules are so often assumed to apply in the cabin, as our guide to sleep apnoea and pilot medical certification explains.

Cabin crew hold neither a licence nor a medical certificate. Under Regulation (EU) No 1178/2011 you hold a cabin crew attestation plus a cabin crew medical report issued under MED.C.030, which must state the date of the assessment, whether you are fit or unfit, the date of your next assessment, and any limitations.

The vocabulary matters here. US-centric pages built around terms such as "waiver" or "special issuance" describe a system that does not exist anywhere in Part-MED Subpart C.

Who examines you and how often

MED.C.005(b) sets an aero-medical assessment before first assignment to duties, and thereafter at intervals of maximum 60 months. Revalidation may be undertaken up to 45 days before expiry, with validity calculated from the previous expiry date.

MED.C.005(c) permits three assessor types: an aero-medical examiner (AME), an aero-medical centre (AeMC), or an occupational health medical practitioner (OHMP). Under MED.D.040 the OHMP route exists only where a Member State's competent authority is satisfied that its national occupational health system meets Part-MED.

That practitioner must be qualified in occupational medicine and must have covered the in-flight working environment and cabin crew safety duties in training or experience. This is why the doctor you see genuinely differs between EU states.

The standard does not change with the language you search in. It is the same rule whether you look for syndrome d'apnées du sommeil as personnel navigant commercial, for Schlafapnoe and Flugbegleiter Flugtauglichkeit, or for slaapapneu and cabinepersoneel medische keuring.

How a sleep apnea cabin crew EASA medical differs from pilot certification

A sleep apnea cabin crew EASA medical differs from pilot certification in three concrete ways, and crew-facing pages almost never state them.

First, there is no mandatory cardiological evaluation. MED.B.015(d) tells pilots that applicants with an established diagnosis of sarcoidosis or sleep apnoea syndrome shall undergo satisfactory cardiological evaluation before their application goes further. AMC3 MED.C.025 imposes no equivalent step on cabin crew, and that is the largest single cost and delay difference between the two routes.

Second, your file never leaves the examining doctor. MED.B.015(e) requires Class 1 applicants with sleep apnoea to be referred to the medical assessor of the licensing authority, and Class 2 applicants to be assessed in consultation with that assessor. The phrase "medical assessor" appears nowhere in Part-MED Subpart C, so cabin crew have no national escalation loop, and equally no authority-level review to fall back on if a local decision goes against them.

Third, the two standards ask different questions. AMC1 MED.C.005 assesses cabin crew on functional ability: the physical and mental capacity to undergo training such as actual fire-fighting, descending an evacuation slide and using Protective Breathing Equipment (PBE) in a simulated smoke-filled environment, to provide first aid, and to manipulate aircraft systems and emergency equipment. The pilot regime turns instead on sudden incapacitation risk.

Obesity is handled differently as well. AMC1 and AMC2 MED.B.025(b) set a Body Mass Index of 35 or above as the pilot threshold for a risk assessment that explicitly includes evaluation of the possibility of sleep apnoea. Subpart C sets no BMI threshold at all; obesity appears once, in AMC2 MED.C.025, as a cardiovascular risk factor that shortens the resting ECG interval to two years.

Why sleep-disordered breathing goes undetected in this workforce

Cabin crew are a high-risk group for sleep problems, and the symptoms of sleep apnoea overlap closely with the symptoms of the roster itself.

The first two figures come from a 2023 scoping review of 27 studies published in the International Journal of Environmental Research and Public Health (IJERPH), which also found diagnosed sleep disorders 3.7 times more prevalent in male cabin crew than in the general population. The second two come from a 2020 survey of 930 active full-time cabin crew published in the same journal.

That 2023 IJERPH review reported fatigue in 63.5% to 77.4% of cabin crew on validated scales, roughly twice the prevalence seen in the general public, with 76.3% scoring moderate-to-high on the Multidimensional Assessment of Fatigue Scale. It also found 59.9% reporting poor sleep quality on the Pittsburgh Sleep Quality Index, and baseline sleep of 6.5 hours per 24 hours for cabin crew against 7.5 hours for pilots.

The safety picture in the 2020 IJERPH survey is blunter. Some 78.2% said fatigue had compromised safety-related tasks and 34.8% reported falling asleep on the jumpseat during critical phases of flight.

A 2025 study in Nutrients of 101 aircrew found 71% reporting sleep disturbances and 60% reporting weight change since starting the career, 38% of them weight gain. That matters because weight gain is associated with obstructive sleep apnoea syndrome (OSAS).

Circadian rhythm disruption, jet lag disorder and shift work sleep disorder produce the same daytime sleepiness that OSAS produces. Crew may therefore blame snoring, morning headaches and microsleeps on the schedule. Our guide to how night shifts hide sleep apnoea symptoms explains that masking effect.

What the respiratory evaluation actually involves

A respiratory evaluation is a standard sleep-medicine work-up in four parts: screening, an objective sleep study, an airway examination and proof that treatment works. The regulation names the requirement but not the tests, so the examining doctor decides what evidence satisfies it.

No published text spells out what "unsatisfactorily treated" means in evidence terms, so here is what examiners commonly want to see: CPAP adherence data showing the percentage of nights used and the average hours per night, a treated AHI from a repeat study, and a normalised Epworth score. Clinicians generally look for consistent nightly use.

If you use a mandibular advancement device, a nasal stent or another non-CPAP option, none of them generate automatic download data. Expect your examiner to ask for objective proof instead, usually a repeat respiratory polygraphy showing a satisfactory treated AHI.

Diagnosed mid-cycle and the 60-month interval trap

A mid-cycle diagnosis is governed by MED.A.020, the general decrease in medical fitness duty, not by your next scheduled medical. Because assessments can be five years apart, most crew meet this rule long before they meet an examiner.

MED.A.020 says crew must not perform duties when aware of any decrease in medical fitness to the extent that the condition might render them unable to discharge their safety duties. It also requires aeromedical advice after surgical operations or invasive procedures, on commencing regular medication use, after significant personal injury or illness causing incapacity, and on pregnancy.

Two practical readings follow, and neither is spelled out in the rule itself. A new diagnosis with significant daytime sleepiness engages the first limb, so seek advice before your next duty. Starting CPAP is not medication in the ordinary sense, but it treats a safety-relevant condition, so declaring it early is the safer course.

You will be asked in writing in any case. The EASA application and medical history form in Annex VI (Part-ARA) carries item 126, "Sleep disorder/apnoea syndrome", as an explicit declarable item. A non-disclosure that surfaces later is a far bigger problem than the condition itself.

Limitation codes, not grounding, are the usual outcome

The realistic result of a treated case is a fit assessment carrying a limitation code, not an unfit one. MED.C.035 and AMC1 MED.C.035 give cabin crew their own codes, separate from the pilot ones.

A managed sleep apnoea case commonly lands on TML or SIC, meaning a shorter review cycle and defined follow-up testing. Under MED.C.035(b) a limitation can only be removed by an AME or an AeMC, or by an OHMP in consultation with an AME, so the practitioner who imposes it is not always the one who can lift it.

The layover problem that pushes crew into non-adherence

Treatment often fails in this workforce for logistical reasons rather than medical ones. That matters, because logistics are exactly what turn a treated case into an unsatisfactorily treated one.

The obstacles repeat on every rotation: carrying a machine through crew security, humidifier water restrictions, absent or incompatible power in crew rest compartments and short-turnaround hotel rooms, and the effect of a cabin altitude of around 8,000 feet on therapy. Our guide to flying with CPAP in Europe and the rules for portable machines covers the equipment and documentation side.

For crew whose problem is snoring or mild-to-moderate obstructive sleep apnoea, an option that needs no power supply can be easier to sustain across a roster. A nasal stent, sometimes described as a nasopharyngeal airway device, sits inside the nostril and holds the airway open mechanically rather than pushing air into it.

Back2Sleep is one such device: a CE-certified Class I soft silicone intranasal stent that keeps the nasal airway open during sleep. It uses no electricity, no tubing and makes no noise, which takes the power socket and the humidifier off the packing list, and the starter kit contains four sizes so you can find your fit without a prescription.

Three limits must be stated plainly. It is not appropriate for severe sleep apnoea. It is never a substitute for CPAP where CPAP has been prescribed for moderate-to-severe disease. And unlike CPAP it produces no automatic adherence data, so if you rely on it, expect your examiner to ask for a repeat sleep study and an Epworth score instead.

Raise it as a discussion point with the AME, AeMC or OHMP conducting your MED.C.025 respiratory evaluation. It is one possible route to the satisfactory result the regulation demands, never a way around the evaluation itself.
