AUX doors open / close
Open: 235 KIAS +/-5
Close: 255 KIAS +/- 5
What is the effect of the AUX doors failing in the open or closed condition?
Open: 10% increase in fuel consumption

For ground starts only, the ignition duty cycle is: __ attempted starts, __ min off, an additional __ attempted starts, and __ min off.
For ground starts only, the ignition duty cycle is: 3 attempted starts, 3 min off, an additional 3 attempted starts, and 23 min off.
Explain “Cruise Flat”
As the throttles advance towards MIL, nozzle position decreases towards 0% until approximately 85%. At this point, the nozzle remains fixed at 16-22% until the throttle is advanced to where the nozzles begin to close towards zero. Best cruise performance is here in cruise flat.
On takeoff, AB light off should occur within __ seconds

What is the serviceable engine oil quantity in each engine?
4 quarts
In the airframe mounted gearbox, automatic shift occurs in the __ to __ % engine RPM range
68-72%
The left engine should be at approximately __% for a crossbreed start.
95%
The fuel low warning system operates on a __ second time delay and illuminates when the fuel level drops to ____ - ____ pounds.
3 second
350-400 lbs
L or R fuel pressure light indicates:
Low fuel pressure of 66.5 psi or less
The generators should come on the line at ___% RPM, and generator dropout should occur at __%.
48%
43%
With the landing gear handle up, the red light and audible warning will activate at altitudes below ____’, at an airspeed less than ___ KIAS +/- __ KIAS with one or both throttles below __% RPM.
With the landing gear handle up, the red light and audible warning will activate at altitudes below 9500’, at an airspeed less than 210 KIAS +/- 10 KIAS with one or both throttles below 96% RPM.
The drag chute can be released by
1) Rotating the T-handle 90 degrees clockwise and pulling it to the second detent or
2) Resetting the T-handle to the stowed position
With fixed flaps, flaps are automatically positioned to half (12 deg / 8 deg) below __K’ and one quarter (0 deg / 8 deg) above __K’. Flaps automatically retract approaching ___ KIAS or ___ IMN. Warning tone goes off if flaps do not retract.
With fixed flaps, flaps are automatically positioned to half (12 deg / 8 deg) below 32K’ and one quarter (0 deg / 8 deg) above 32K’. Flaps automatically retract approaching 550 KIAS or .95 IMN. Warning tone goes off if flaps do not retract.
With the LCOSS on, a G warning town will come on at ___ Gs. Tone will intensify as G increases.
+6.5
What aircraft altitude corresponds to 10K’ cabin altitude?
25K’
With the ENG ICE switch on, expect a __% loss of thrust at MIL and a __% loss of thrust at MAX. At MIL power, opening the anti ice valve may produce a ___ lb/hr decrease in fuel flow, and a __% increase in nozzle opening indication.
With the ENG ICE switch on, expect a 9% loss of thrust at MIL and a 6.5% loss of thrust at MAX. At MIL power, opening the anti ice valve may produce a 100 lb/hr decrease in fuel flow, and a 2% increase in nozzle opening indication.
A short trip around the pattern takes ~___#

360 KIAS
Max sustained turn performance can be felt by light buffet at ___-___ units AOA
15-17
Stall occurs at ___-___ units AOA
