Answer 19

Sea level; 25,000 ft MSL
6,000 ft MSL

~30 seconds at 30,000 ft

Question 21

650

Question 22

List 5 possible causes of a fuel pressure light

Answer 22

Corresponding boost pump failure
Fuel leak
Generator phase failure
Fuel pressure sensor malfunction
Momentary blink due to fuel requirement surge (AB initiation)

Question 23

MIL power fuel flow on the ground (sea level)

Answer 23

2100-2700 pph

Question 24

When does the engine anti-ice light illuminate?

Answer 24

When the switch is placed to MAN ON or in the event of right AC failure (no crossover)

Question 25

When is engine-anti ice always on?

Answer 25

Below 65% RPM (no light illuminates)

Question 26

Where does the bleed air come from for anti-ice, where does that air go, and how does anti-ice affect EGT and thrust?

Answer 26

When anti-ice is on, compressor 8th-stage air is directed to the inlet guide vanes and bullet nose of the engine. At engine speeds of 94-98% RPM, an increase in EGT of ~15 C is normal. A loss of thrust of 180 pounds +/- 10 pounds can be expected with anti-ice on, which equates to an ~8.5% loss in MIL and ~5.5% loss in MAX.

Answer 27

50-120 psi

Question 28

When does the Oxygen light illuminate?

Answer 28

-When the oxygen quantity indicator reads 1 liter or less of LOX -Light may blink with less than 3 liters due to sloshing

Answer 29

When either fuel quantity indicator reads below 250 pounds for 7.5 seconds

Question 30

What are the fuel imbalance indications?

Answer 30

0-50 pounds: no display ~60-190 pounds: white difference display ~200 pounds or more: red difference display

Question 31

Solo fuel imbalance limitation?

Answer 31

Don't allow the right fuel quantity to be more than double the left fuel quantity when solo

Question 32

Question 38

During a battery start, which lights should be illuminate prior to applying air? In what order should the lights extinguish?

Answer 38

All lights except Oxygen and Fuel Low are illuminated prior to applying air. Lights extinguish in following order: 1) Flt Hydraulics (once air is connected) 2) when right gen reaches cut-in speed: rt fuel px, rt gen, XMFR Rect Out, Anti-Ice 3) Util Hydr (once left air connected) 4) left fuel px (when left throttle idle) 5) Left Gen (when left gen reaches cut-in speed)
