(ii)  
for operations under VFR at night 0.15 × the distance travelled from the back of the FATO.

(c)  
Obstacles may be disregarded if they are situated beyond:

(1)  
7 × rotor radius (R) for day operations, if it is assured that navigational accuracy can be achieved by reference to suitable visual cues during the climb;

(2)  
10 × R for night operations, if it is assured that navigational accuracy can be achieved by reference to suitable visual cues during the climb;

(3)  
300 m if navigational accuracy can be achieved by appropriate navigation aids; or

(4)  
900 m in all other cases.

Chapter 2 — Performance class 1

CAT.POL.H.200 General
Helicopters operated in performance class 1 shall be certified in Category A or equivalent.

CAT.POL.H.205 Take-off
(a)  
The take-off mass shall not exceed the maximum take-off mass specified in the AFM for the procedure to be used.

(b)  
The take-off mass shall be such that:

(1)  
it is possible to reject the take-off and land on the FATO in case of the critical engine failure being recognised at or before the take-off decision point (TDP);

(2)  
the rejected take-off distance required (RTODRH) does not exceed the rejected take-off distance available (RTODAH); and

(3)  
the TODRH does not exceed the take-off distance available (TODAH).

(4)  
Notwithstanding (b)(3), the TODRH may exceed the TODAH if the helicopter, with the critical engine failure recognised at TDP can, when continuing the take-off, clear all obstacles to the end of the TODRH by a vertical margin of not less than 10.7 m (35 ft).

(c)  
When showing compliance with (a) and (b), account shall be taken of the appropriate parameters of CAT.POL.H.105 (c) at the aerodrome or operating site of departure.

(d)  
That part of the take-off up to and including TDP shall be conducted in sight of the surface such that a rejected take-off can be carried out.

(e)  
For take-off using a backup or lateral transition procedure, with the critical engine failure recognition at or before the TDP, all obstacles in the back-up or lateral transition area shall be cleared by an adequate margin.

CAT.POL.H.210 Take-off flight path
(a)  
From the end of the TODRH with the critical engine failure recognised at the TDP:

(1)  
The take-off mass shall be such that the take-off flight path provides a vertical clearance, above all obstacles located in the climb path, of not less than

10.7 m (35 ft) for operations under VFR and 10.7 m (35 ft) + 0.01 × distance DR for operations under IFR. Only obstacles as specified in CAT.POL.H.110 have to be considered.
