For Performance Class 3 operations, when is the take-off phase considered to end during a departure?
  • A
    As the helicopter reaches VY or 200 ft.
  • B
    At DPATO.
  • C
    On passing the TODR.
  • D
    Below 200 ft

1. According to CAT.POL.H.400 - General (PC3): Operations may be conducted to/from an aerodrome or operating site located outside a congested hostile environment without an assured safe forced landing capability:

(1) during take-off, before reaching Vy (speed for best rate of climb) or 200 ft above the take-off surface; or

(2) during landing, below 200 ft above the landing surface.

2. According to GM1 CAT.POL.H.400(c) - General: Take-off flight path is not used in Performance Class 3 and, consequently, the term ‘take-off and landing phases’ is used to bound the limit of exposure. For the purpose of Performance Class 3, the take-off and landing phases are considered to be bounded by:

(1) during take-off, before reaching Vy (speed for best rate of climb) or 200 ft above the take-off surface; and

(2) during landing, below 200 ft above the landing surface.
