When determining the take-off performance for a Performance Class 1 helicopter, the accountability for the headwind must be not:
  • A
    less than 50% of the reported headwind component.
  • B
    more than 50% of the reported headwind component.
  • C
    more than 150% of the reported headwind component.
  • D
    more than 80% of the reported headwind component.

Minimum levels of performance are required for all the phases of flight, assuming a critical engine at any point.

According to CAT.POL.H.105 - General:

When showing compliance, the operator must ensure that the mass of the helicopter never exceeds any limits at any stage, including in-flight re-planning and account shall be taken of the following parameters:

(1) mass of the helicopter;

(2) the helicopter configuration;

(3) the environmental conditions, in particular:

(i) pressure altitude and temperature;

(ii) wind:

(A) for take-off, take-off flight path and landing requirements, accountability for wind shall be no more than 50% of any reported steady headwind component of 5 kt or more;

(B) where take-off and landing with a tailwind component is permitted in the AFM, and in all cases for the take-off flight path, not less than 150 % of any reported tailwind component shall be taken into account;

(4) the operating techniques; and

(5) the operation of any systems that have an adverse effect on performance.
