9.04  Net take-off flight path requirements

Obstacle clearance
 (1) For the purposes of paragraph 9.02(a), it is a requirement that, assuming a failure of an aeroplane engine that is recognised at V1 appropriate to a dry runway at the aerodrome, the aeroplane vertically clears all obstacles within the net take-off flight path by at least:
 (a) 35 ft, if the aeroplane for the take-off will use a bank angle not exceeding 15°; or
 (b) 15 ft, if the aeroplane:
 (i) is intending to use a bank angle not exceeding 15° for the take-off; and
 (ii) the take‑off will be conducted in compliance with paragraph 9.03(1)(d); or
 (c) 50 ft, if the aeroplane for the take-off will use a bank angle exceeding 15°; or
 (d) 30 ft, if the aeroplane:
 (i) is intending to use a bank angle exceeding 15° for the take-off; and
 (ii) the take-off will be conducted in compliance with paragraph 9.03(1)(d).
 (2) For the purposes of subsection (1), an obstacle is deemed to be within the net take‑off flight path if the lateral distance from the obstacle to the aeroplane's intended flight path is within a distance calculated in accordance with subsection (2A) or (5).
 (2A) For the purposes of subsection (2), the distance is that which does not exceed the following, subject to the limitations mentioned in subsection (3) or (4) (whichever is applicable):
 (a) 90 m plus (0.125 x D);
 (b) if the aeroplane has a wingspan less than 60 m—the distance worked out using the formula:

 (half the wingspan of the aeroplane) + 60 m + (0.125 x D).
 (2B) In subsection (2A):
D means the horizontal distance the aeroplane will travel from:
 (a) the end of the take-off distance available at the aerodrome; or
 (b) if a turn is scheduled before the end of the take-off distance available—the end of the take-off distance required for the take-off.

Maximum distance limitations
 (3) If the intended flight path does not require a track change exceeding 15°, the distance mentioned in paragraph (2A)(a) or (b) is limited to:
 (a) a maximum of 600 m; or
 (b) if the portion of the flight from the departure end of the runway to the lowest safe altitude for the route can be conducted with a navigation specification of RNP 0.2 or better—a maximum of 300 m.
 (4) If the intended flight path requires a track change exceeding 15°—the distance mentioned in paragraph (2A)(a) or (b)
