d.
Ground start (maximum overshoot of
20 degrees C for 10 seconds):
550 degrees C
e.
Airstart (maximum overshoot
50 degrees for 10 seconds):
600 degrees C
3.
speed in percent rpm
4.
EGT/RPM warning light: if either EGT or N1
shaft speed exceeds operation limits, ECA
signals CWS, illuminating EGT/RPM
warning (650 +/- 8 0C / 112.4 +/- 1 percent N1 )
5.
ECA (lane failure) advisory light: indicates a
failed single ECA lane (ECA is still providing
fuel trim)
6.
ECA failure caution light: indicates both
ECA lanes inoperative
7.
ACCEL caution light: indicates initial shot
solenoid or steam ingestion bleed valve is
not in the commanded position
NOTE: Initial shot solenoid becomes
operational on engine start--requires no

a.
Slower engine acceleration on
approach
b.
10% less MRT thrust and increase in
fuel flow apparent
8.
