Thrust Control System (ATTCS)?

Answer 23

To provide automatic thrust increase if ATTCS
is previously armed and any one of the following
conditions is true on takeoff or go-around—OEI

Answer 27

Max accumulated time—5 minutes; Maximum

Yes, dry motor the associated engine for 30

seconds prior to start (AOM 3-11)

Question 31

When can HP thermal bow occur? If an engine
restart is desired within that time period,what is
the recommended procedure?

Answer 31

When engine starts are initiated between 15
and 180 minutes after an engine shutdown. Dry
motor the associated engine prior to start for
15 seconds or until N2 reaches 23% (whichever
occurs first). After completion of this procedure,
a normal engine start sequence can be initiated
any time after 3 minutes and before 40 minutes
have elapsed. (AOM 3-11)
