CS 23.2105 Performance data

(a)Unless otherwise prescribed, an aeroplane must meet the performance requirements of this Subpart in:

(1)still air and standard atmospheric conditions at sea level for all aeroplanes; and

(2)ambient atmospheric conditions within the operating envelope for:

(i)Level-1 high-speed and Level-2 high-speed aeroplanes; and

(ii)Level-3 and Level-4 aeroplanes.

(b)Unless otherwise prescribed, the applicant must develop the performance data required by this Subpart for the following conditions:

(1)airport altitudes from sea level to 3 048 m (10 000 ft); and

(2)temperatures above and below standard day temperature that are within the range of operating limitations if those temperatures could have a negative effect on performance.

(c)The procedures used for determining take-off and landing distances must be executable consistently by pilots of average skill in atmospheric conditions expected to be encountered in service.

(d)Performance data determined in accordance with CS 23.2105(b) must account for losses due to atmospheric conditions, cooling needs, and other demands on power sources.
