additional conditions, if specified by the competent authority, taking into account the aeroplane type characteristics, orographic characteristics in the approach area, available approach aids and missed approach/balked landing considerations.

Chapter 4 — Performance class C

CAT.POL.A.400 Take-off
(a)  
The take-off mass shall not exceed the maximum take-off mass specified in the AFM for the pressure altitude and the ambient temperature at the aerodrome of departure.  

(b)  
For aeroplanes that have take-off field length data contained in their AFM that do not include engine failure accountability, the distance from the start of the take-off roll required by the aeroplane to reach a height of 50 ft above the surface with all engines operating within the maximum take-off power conditions specified, when multiplied by a factor of either:

(1)  
1.33 for aeroplanes having two engines;

(2)  
1.25 for aeroplanes having three engines; or

(3)  
1.18 for aeroplanes having four engines,

shall not exceed the take-off run available (TORA) at the aerodrome at which the take-off is to be made.
(c)  
For aeroplanes that have take-off field length data contained in their AFM which accounts for engine failure, the following requirements shall be met in accordance with the specifications in the AFM:

(1)  
the accelerate-stop distance shall not exceed the ASDA;

(2)  
the take-off distance shall not exceed the take-off distance available (TODA), with a clearway distance not exceeding half of the TORA;

(3)  
the take-off run shall not exceed the TORA;

(4)  
a single value of V1 for the rejected and continued take-off shall be used; and

(5)  
on a wet or contaminated runway the take-off mass shall not exceed that permitted for a take-off on a dry runway under the same conditions.

(d)  
The following shall be taken into account:

(1)  
the pressure altitude at the aerodrome;

(2)  
the ambient temperature at the aerodrome;

(3)  
the runway surface condition and the type of runway surface;

(4)  
the runway slope in the direction of take-off;

(5)  
not more that 50 % of the reported headwind component or not less than 150 % of the reported tailwind component; and

(6)  
the loss, if any, of runway length due to alignment of the aeroplane prior to take-off.

CAT.POL.A.405 Take-off obstacle clearance
(a)  
The take-off flight path with OEI shall be determined such that the aeroplane clears all obstacles by a vertical distance of at least 50 ft plus 0.01 × D, or by a horizontal distance of at least 90 m plus 0.125 × D, where D is the horizontal distance the aeroplane has
