Brakes: When does CH 1 braking work
Only when LDG gear handle is down
Brakes: When does CH 2 work
LDG gear handle up or down
Brakes: When does Anti-skid light come on and what does it mean
Above 5 knots
Braking effectiveness is reduced by 25-50%
Brakes: What does Anti-skid light flashing mean?
Total electrical failure of at least one brake

60˚ full
43˚ with RMLG down and locked
Describe lights at startup
Batt on, 2, 1, 0
Power test, 4, 1, 3, 0 (adds FLCS PMG and FLCS channels)
Main Power, 2, 1, 0
Eyebrow: HYD/OIL, ENGINE
Caution: SEC, ELEC SYS, FLT CONT SYS
How long do you motor the JFS
1 minute
What are the JFS limitations
Run for 4 minutes
Cool for 5
1 minute in between start attempts
What does a flashing JFS run light mean?
1/sec = non-critical failure, continue 2/sec = critical failure, don’t continue
When is the JFS recharged
40-60 seconds after 12% RPM
When does HYD and Fuel PX increase
15% RPM
When does the SEC light go out?
18%
When should engine light off occur
20 seconds after IDLE
RPM leads FTIT
