25.345(c) High lift devices (Procedure flight condition)
ED Decision 2003/2/RM
1 En-route conditions are flight segments other than take-off, approach and landing. As applied to the use of high lift devices the following flight phases are to be included in en-route conditions:
— holding in designated areas outside the terminal area of the airport, and
— flight with flaps extended from top of descent.
The following flight phases are not to be included in en-route conditions:
— portion of the flight corresponding to standard arrival routes preceding the interception of the final approach path, and
— holding at relatively low altitude close to the airport.
2 To apply CS 25.341(a) gust conditions to CS 25.345(c), the speeds VFC and VFD should be determined for the flap positions selected in en-route conditions.
These procedures should ensure proper speed margins for flap retraction in the case of severe turbulence when the aeroplane is in a low speed en-route holding configuration.
3 The manoeuvre of CS 25.345(c)(1) is to be considered as a balanced condition. (See CS 25.331(b) for definition.)
