Regulation (EC) No 216/2008 of the European Parliament and of the Council (repealed)Show full title

4. Aircraft performance and operating limitations

4.a. An aircraft must be operated in accordance with its airworthiness documentation and all related operating procedures and limitations as expressed in its approved flight manual or equivalent documentation, as the case may be. The flight manual or equivalent documentation must be available to the crew and kept up to date for each aircraft.

4.b. The aircraft must be operated in accordance with the applicable environmental documentation.

4.c. A flight must not be commenced or continued unless the aircraft's scheduled performance, considering all factors which significantly affect its performance level, allows all phases of flight to be executed within the applicable distances/areas and obstacle clearances at the planned operating mass. Performance factors which significantly affect take-off, en-route and approach/landing are, particularly:

(i)

operating procedures;

(ii)

pressure altitude of the aerodrome;

(iii)

temperature;

(iv)

wind;

(v)

size, slope and condition of the take-off/landing area; and

(vi)

the condition of the airframe, the power plant or the systems, taking into account possible deterioration.

4.c.1. Such factors must be taken into account directly as operational parameters or indirectly by means of allowances or margins, which may be provided in the scheduling of performance data, as appropriate to the type of operation.
