1. 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 as set out in CAT.POL.H.400(c) and 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.
2. According to CAT.POL.H.400(c): 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.
