The operation of complex and non-complex aeroplanes is governed by comprehensive Swiss and European regulations. FOCA is responsible for certification and for ensuring that all applicable regulations are complied with at all times.
An aeroplane is classified as complex if it belongs to the category of «complex aircraft» because of its construction, size or configuration. Aircraft are classified as «complex» if:
- they have a certified maximum take-off weight exceeding 5,700 kg or
- they have a maximum approved passenger seating configuration of more than 19, or
- they are certified for operation with a crew of at least 2 pilots, or
- they are equipped with one or more jet engines or with more than one turboprop engine.
If the aircraft does not meet any of the above criteria, it is considered non-complex.
