Division 9—Rotorcraft performance — performance class 3

10.41  Performance class 3 — take‑off
 (1) For item 1 of the table in section 10.07, the requirements for the take‑off stage of a flight of a rotorcraft are the requirements stated in this section.
 (2) The take‑off weight of the rotorcraft must not exceed the maximum weight, mentioned in the rotorcraft's flight manual, required:
 (a) for the type of take‑off procedure to be used; and
 (b) to:
 (i) hover in ground effect, with the rotorcraft's engines operating at the power required for hover in ground effect, in the meteorological conditions existing at the time of take‑off; or
 (ii) if the rotorcraft cannot hover in ground effect due to the location of, or the terrain at, the departure aerodrome for the flight — hover out of ground effect, with the rotorcraft's engines operating at the power required for hover out of ground effect, in the meteorological conditions existing at the time of take‑off; and
 (c) to have enough additional power available for the type of take‑off procedure to be used while hovering in ground effect or out of ground effect.
 (3) 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.

10.42  Performance class 3 — take‑off and initial climb
 (1) For item 2 of the table in section 10.07, the requirements for the take‑off and initial climb stage of a flight of a rotorcraft are the requirements stated in this section.
 (2) The rotorcraft must clear an obstacle, if any, under the take‑off flight path by at least the adequate vertical margin, for the rotorcraft, for the take‑off and initial climb 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 the minimum safe height for the flight under Part 91 of CASR or the Part 91 Manual of Standards, 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 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
