AMC2 CAT.POL.A.210 Take-off obstacle clearance    

CAA ORS9 Decision No. 1

EFFECT OF BANK ANGLES

(a) The AFM generally provides a climb gradient decrement for a 15° bank turn. For bank angles of less than 15°, a proportionate amount should be applied unless the manufacturer or AFM has provided other data.

(b) Unless otherwise specified in the AFM or other performance or operating manuals from the manufacturer, acceptable adjustments to assure adequate stall margins and gradient corrections are provided by the following table:

Table 1

Effect of bank angles

Bank	Speed	Gradient correction
15°	V2	1 x AFM 15° gradient loss
20°	V2 + 5 kt	2 x AFM 15° gradient loss
25°	V2 + 10 kt	3 x AFM 15° gradient loss
