T-45C TS, ADV, & IUT ENG-05
Engine and Related Systems Malfunctions
NOTE: If an ECA lane failure occurs, a momentary thrust
fluctuation may be experienced. With a dual lane failure, engine
EGT, fuel flow, and rpm should be monitored and the throttle
carefully controlled. Manual fuel control use should be considered
only if a dual lane failure is indicated and engine instability exists;
for instance, stalls or surges.
XI. Initial shot solenoid failure 1.8.1.1.18.1
A. Indications
1. MASTER ALERT light flashes
2. Caution tone sounds
3. ACCEL caution light illuminates
B. Verifications: Same as indications
C. Effects on flight safety
1. Above 9500 +/- 300 feet MSL - possible engine surge/stall due to
rapid throttle movement
2. Below 7700 +/- 500 feet MSL - slow spoolup time due to reduced
surge margin during rapid acceleration
3. Carrier landing not permitted
XII. Steam ingestion bleed valve failure 1.8.1.1.19.1
A. Indications
1. MASTER ALERT light flashes
2. Caution tone sounds
3. ACCEL caution light illuminates
B. Verifications
1. Valve OPEN (Shore-based takeoff)
a. RPM may be lower than normal
b. EGT may be higher than normal
c.
Slower than normal aircraft acceleration
d. Reduced climb performance
2. Valve CLOSED (Catapult takeoff) - Engine surge/stall due to steam
ingestion
