T-6 By the Numbers (2) Flashcards
Max ITT for start
1000* C
Time for ITT to start rising after fuel flow indication during start
10 seconds
Altitude/Airspeed parameters for ejection seat
0/0
Minimum speed to maintain while maneuvering to intercept ELP
120 KIAS
N1 with engine flameout (speeds below 8% not included)

Time for prop to unfeather after N1 reaches ~45%
15-20 seconds
PCL to IDLE for PMU off airstart (look for ITT rise w/in 10 seconds or abort)
13% N1
Initial fuel flow during airstart
75-80
Amp reading after airstart
> 30 amps
Time for starter to drain battery if generator is not reset
10 minutes
Time for prop to come out of feather after PROP SYS CB is pulled
15-20 seconds
