take‑off and initial climb stage of the flight.
 (4) The rotorcraft must:
 (a) remain outside the rotorcraft's avoid area of the HV envelope; or
 (b) if it is necessary for the rotorcraft to enter the rotorcraft's avoid area of the HV envelope to avoid an accident or incident — not remain inside that area for longer than the minimum period necessary to avoid the accident or incident.

10.43  Performance class 3 — en route
  For item 3 of the table in section 10.07, the requirements for the en route stage of a flight of a rotorcraft are the following:
 (a) the weight of the rotorcraft must allow the rotorcraft, with all engines operating, to achieve the minimum flight altitude for each point in the en route stage of the flight;
 (b) the rotorcraft must be flown in a way that minimises the time during the en route stage of the flight in which a suitable forced landing area, for the flight, is not available.

10.44  Performance class 3 — approach and landing, or baulked landing
 (1) For item 4 of the table in section 10.07, the requirements for the approach and landing, or baulked landing stage of a flight of a rotorcraft are the requirements stated in this section.
 (2) The landing weight of the rotorcraft must not exceed the maximum weight, mentioned in the rotorcraft's flight manual, required:
 (a) for the type of approach procedure to be used; and
 (b) to achieve:
 (i) a hover in ground effect, with the rotorcraft's engines operating at the power required for landing; or
 (ii) if the rotorcraft cannot achieve a hover in ground effect due to the location of, or the terrain at, the aerodrome — a hover out of ground effect, with all engines operating; and
 (c) to achieve a baulked landing, with all the rotorcraft's engines operating, at any point of the flight path for the approach and landing; and
 (d) to clear an obstacle, if any, by at least the adequate vertical margin, for the rotorcraft, for the approach and landing, or baulked landing stage of the flight.
 (3) If:
 (a) the rotorcraft is operating over a populous area and the requirements stated in section 10.26 are not met; and
 (b) an engine becomes inoperative;
  then, until the rotorcraft reaches a point in the flight from which it may land at an aerodrome with the engine inoperative, the rotorcraft must clear an obstacle, if any, under the flight path to a suitable forced landing area for the flight by at least the adequate vertical margin for the rotorcraft for the approach and landing, or baulked landing stage of the flight.
 (4) The rotorcraft must:
 (a) remain outside the rotorcraft's
