A comprehensive legal framework ensures that pilots and aircrews are trained to fly safely. The European rules focus increasingly on the competences gained through training, rather than on fulfilling formal requirements.
The rules on Flight Time Limitations include obligations for Member States, airlines and aircrew to ensure safe duty rosters. They also contain flight duty limits per day, week, month and year, in addition to minimum rest per day and month, depending on previous duties. The aim is to ensure that flight and cabin members are sufficiently alert to perform safety functions on board aircraft.
