Medevac crew: composition, qualifications and rostering constraints
A medevac crew combines two distinct teams: the flight crew, rated on the aircraft and bound by flight and duty time rules, and the medical team, qualified for the clinical case and the equipment on board. A shift is only covered when both are complete and compatible with the mission likely to come.
This is what makes air ambulance rostering irreducible to other segments. Where an airline pairs one crew to one flight, a medevac operator has to pair, on every single shift, two teams governed by different qualification frameworks, and frequently employed by different organisations. This article sets out who makes up each team, what European rules require of the flight crew side, and how to roster both at once.
Who is on a medevac crew?
Two groups, whose availability follows different logics.
The flight crew: the pilots, joined in many helicopter emergency medical service (HEMS) operations by a HEMS technical crew member. European rules set the minimum HEMS crew at two pilots, or one pilot and one HEMS technical crew member, by day as by night; it may drop to a single pilot only in situations the regulation lists, such as when the medical passenger needs the technical crew member's assistance in flight. The technical crew member is a crew member without being a pilot, and an aviation role rather than a medical one: their primary tasks are to assist the commander with collision avoidance, landing site selection, obstacle detection on approach and take-off, and checklist reading. Their constraints are aviation constraints: training, checks, flight and duty time limitations, mandatory rest.
The medical team: in aviation regulatory terms, it is not part of the crew. In HEMS, the European regulation calls doctors, nurses and paramedics carried on board "medical passengers", and requires them to be briefed before any flight or series of flights on the working environment, the onboard medical and emergency equipment, and entry and exit procedures. Its composition varies substantially by national model (an emergency physician on board in some countries, nurse or paramedic teams in others, with variants by case severity and transport type). Its constraints are clinical: specialty, credentials, training on the equipment carried, and a working-time framework that is not the crew's.
The planning consequence: these two worlds are not governed by the same rules, often not even held in the same system. Yet they have to converge on the same shift.
What do the rules require of the flight crew?
For helicopters, Part-SPA of Regulation (EU) No 965/2012 devotes a full subpart to HEMS. Several of its requirements translate directly into rostering constraints:
| Requirement | What it says | What it means for the roster |
|---|---|---|
| Crew composition (SPA.HEMS.130(e)) | Two pilots, or a pilot and a technical crew member | The second seat is part of the shift |
| Continuity of the crew concept (SPA.HEMS.130(e)(3)) | Crew composition managed for the whole mission | The planned crew holds until the mission ends |
| Commander experience (AMC1 SPA.HEMS.130(a)) | 1,000 h as PIC, 500 on helicopters, or a HEMS co-pilot route | Not every pilot can command, least of all at night |
| Instrument training without an instrument rating (SPA.HEMS.130(d)) | Valid for 6 calendar months | A short validity to track per pilot |
| HEMS proficiency and line checks (SPA.HEMS.130(f)) | Valid for 12 calendar months | Checks to build into the workload |
For aeroplanes, no equivalent subpart exists: the flight crew follows the general commercial air transport rules (type rating, recency, operator checks), and the flight time regime described in our medevac rostering guide, which moves to Subpart FTL (B) on 15 October 2028.
Why is qualification matching so binding?
A medevac mission requires a specific combination, not just "a crew":
- Aircraft type: pilots must be current and rated on the aircraft on duty;
- Mission type: neonatal transport, intensive care or long-range repatriation each call for particular skills, set by the clinical framework and the mission protocol rather than by aviation rules;
- Onboard equipment: incubators, ventilation and assist devices require dedicated training held by only part of the team;
- Destination constraints: document validity, visas, permissions, routinely underestimated on international repatriation.
A shift is genuinely covered only when the intersection of all these conditions is non-empty. A presence sheet cannot show that; it takes an assignment engine that treats qualifications as blocking constraints.
How do you roster two teams at once?
- Roster the shift, not the people separately. The unit to cover is the complete slot (flight deck plus medical). Planning the two teams independently mechanically produces bases that are open on paper and unable to launch.
- Make qualifications blocking. An assignment that fails to assemble the required combination should be refused by the tool, not flagged afterwards.
- Track validity as a resource. A qualification expiring mid-season removes an available crew: recurrent training has to be anticipated and built into the production workload.
- Identify the rare combinations. Some skills are held by only a handful of people, such as night HEMS command, and they set the operator's real capability on specialist missions. They deserve explicit tracking, and their rest deserves protecting first.
On the flight crew side, this is the matching SkAI Tech performs: Smart Flight Assignment pairs missions with crew whose qualifications fit, against the applicable rules, and regenerates the assignments a new unavailability affects. Crew, qualifications and flights are read from the operator's existing system, which stays the single source of truth, and assignments are written back to it.

FAQ
Does every medevac flight need a physician on board?
No: it depends on the national model, the mission type and the patient's condition. Some countries rely on paramedic teams; others carry a physician as standard. European aviation rules do not set the composition of the medical team: it is defined by the applicable health framework and the mission protocol.
Is the HEMS technical crew member part of the medical team?
No. The HEMS technical crew member is a crew member assigned by the operator to assist the pilot, in the aircraft or on the ground, and may operate specialised onboard equipment. They count in the minimum HEMS crew composition, and their availability binds the roster as tightly as the pilot's.
How do you handle expiring qualifications?
By treating them as a rostering constraint: anticipate recurrent training, build it into the workload, and refuse assignments whose validity expires before the shift ends. An expired qualification is an unavailability, not just a warning.
Do medical teams and flight crews share the same working-time limits?
No, and that is a structural difficulty of the segment: flight crew fall under aviation rules (flight time, duty, rest), the medical team under employment law and health-sector rules. The roster has to satisfy both frameworks at once.
