51.8 Calculation of performance planning information

51.8.2 Describe the:

(a) Category A (Performance Class 1) take-off technique.

(b) Category B take-off technique.

51.8.4 Calculate the maximum take-off weight (MTOW), restricted by the following performance limitations:

(a) Category A (Performance Class 1) operations

(b) Category B operations

(d) OGE hover capability

(e) en route restrictions

(f) landing restrictions, both Categories A and B.

51.8.6 Calculate the critical decision point (CDP) and take-off safety speed (V2/VTOSS), given the available field length and conditions.

51.8.8 Calculate the rejected take-off (RTO) and continued take-off (CTO) distances, in given conditions.

51.8.10 Calculate the required field length, at a given take-off weight and conditions, using the Category A (Performance Class 1) take-off technique.

51.8.12 Calculate the take-off distance required, at a given take-off weight and conditions, using the Category B take-off technique.

51.8.14 Calculate the payload available given a performance limited take-off weight.

51.8.16 Calculate the climb performance capability of a helicopter:
