T-45C TS, ADV, & IUT ENG-05
Engine and Related Systems Malfunctions
B. Verifications
Depending upon current throttle settings:
1. RPM decreases
2. EGT decreases
3. Fuel flow decreases
NOTE: Thrust available will be governed by maximum RPM
obtained. The thrust may be reduced by as much as one third of
normal throttle value. Very low idle RPM may occur, and the throttle
must be handled carefully to avoid stall or flameout.
C. Effects on flight safety
1.
Limited throttle movement because sudden throttle movements
may result in engine overspeed or overtemp
2.
Possible reduction in thrust available may limit waveoff capabilities
3.
RPM should not exceed 95 percent below 20,000 ft or 90 percent
above 20,000 ft
X. ECA failure (no trim) 1.8.1.1.9.2.1
A. Indications
1. MASTER ALERT light
2. Caution tone sounds
3. ECA 2 caution light
NOTE: The caution advisory panel indications for an ECA failure
(no trim) are the same as for full trim ECA failure.
B. Verifications
1. RPM may increase
2. EGT may increase
3. Fuel flow may increase
C. Effects on flight safety
1. Limited throttle movement because sudden throttle movements
may result in engine underspeed/overspeed, overtemp, or flameout
2. RPM should not exceed 95 percent below 20,000 ft or 90 percent
above 20,000 ft
