(1) The start procedure can be manually stopped at any time as follows:

NOTE: During the automatic start procedure, the automatic abort feature is active only when the starter is engaged. The starter cutout speed varies as a function of ambient temperature. The N2 speed is 47% at T2= -40 deg.F (-40.00 deg.C) and 54% at T2= 86 deg.F (30.00 deg.C). When N2 speed is above these values, you must manually discontinue the engine start.

(a) On the center pedestal, on ENG panel 115VU:
1 Put the ENG/MASTER 1(2) control switch to the OFF position.
2 Put the ENG/MODE selector switch is in the NORM position.
(b) On the ENG section of the overhead control and indicating panel 22VU:
1 Put the MAN START 1(2) switch in the OFF position.
(c) N1 and N2 rotor speeds will decrease the zero (0 RPM).
