General Procedures Flashcards
Fuel Critical ICAW is set at
1000lbs
28V LOW and 28V DIS lights come on for 1 sec and then go off when
During S BIT
S BIT will be performed when
28V Batt is set to ON
28V will come on and stay on when
S BIT is complete
If 28 V low light is flashing, what must be done to ensure successful IPP start
IPP must be started within 30 sec
What happens if 28V low light flashes for more then 60 secs
28V Batt will automatically turn off - 28 V Batt switch must be turned off and Batt charged
How long after turning Batt switch to ON will the Left MFD turn on
2 min
what is the local radio freq
335.8
When is the IPP switch functional
15 seconds after 28 V batt is turned on after the VMC is turned on.
How long must the IPP switch be held in the START position to allow the 270V batt system to perform start up BIT
3 secs
When IPP switch is set to START..
270V low and 270 V DIS lights will flash 1 time
270 V DIS light will come on to indicate that
270 Batt is discharging
If 270V LOW light is illuminated….
IPP start can continue to be performed
IPP switch will Automatically return to ——- when released
AUTO
IFF IPP has a failure during start or operation……..
IPP should AUTO shutdown
IPP start sequence can only be stopped before combustor light turns solid by…….
pushing IPP EMER OFF FIRE light.
Whatr must you do if IPP EMER OFF is pressed
ensure 270V DIS light turns off - if light does not turn off, Press IPP EMER OFF a second time and inspect after 5 secs
IPP Combustor light will turn solid……
approx 30 secs after START is selected and IPP is at command speed
During IPP operation, IPP can have speed fluctuations which is
Normal and can be heard
If Left MFD does not come available within ——– IPP must be——-
5 mins, shutdown to troubleshoot
When IPP combustor light stops flashing and become solid ensure that ………
270V DIS light turns off
Ensure 28V DIS light is not on after……..IPP COMB light comes on Solid

How many times can you attempt engine motoring with GEN HOT 1 and 2 ICAW shown
1 time
IF GEN HOT 1 and 2 does not go away during 2 min Motor what must be down
Motoring must be stopped for trouble shooting

if two start attempts are made with 120 min, ESG must have
a 120 min cooldown period or 10 min of IPP operation to cool down ICC 1 &2
If overheating component ICAW asserts during EnG motoring…..
motoring must be stopped and IPP must cont to run to cool components
GEN HOT 1&2 ICAW asserts prior to Eng run, what must you do?
Motor Engine
Fuel Hot ICAW asserts before Eng operation - what must not happen
do not attempt eng operation
During Engine operation. GEN OIL Fail 1&2 Assert what must you do
If GEN oil Fail 1&2 does not go away once engine reaches idle, ENG operation must be stopped to troubleshoot.
IF ETR higher the idle is required - you must operate ENG for ———- before advancing throttle
