Fuel/oil heat exchanger
34
What should you do if the ENGINE FIRE PUSH switch light goes out?
Test the fire detect circuit
35
What should you do if the EFC fails?

T/O, LDG, patterns
38
With engine synch on, failure of the left engine will call the right engine to roll back how much?
1.5%
39
What does pushing the engine fire switch do?
Shuts off fuel and hydraulics to the engine, turns off the generator, and arms the fire bottles
40
Do the fire extinguishers dispense halon into the engine all at once?
YES
41
What should be done with the bleed air selector if the engine fails during an ACM OFF takeoff?
Leave bleed air selector in the OFF position until 2200' AGL or clear of obstructions
42
What do the pre-check selector valves do?
Ensure proper operation of shutoff during pressure refueling
43
How many bays are in each wing tank?
3
44
What is the capacity of the fuel feed chamber?
135 pounds (20 gallons)
45
How does fuel gravity feed?
From the aft cabin tank into the aft fuselage tank to the mid tanks
46
What is the fuel temperature limitation?
-40-50 deg C
47
How long does pressure (primary) refueling take?
15 minutes
48
How many fuel probes are in the fuselage?
4
49
What transfers fuel from the midtanks to the wing tanks?
An electric transfer pump
50
What two conditions must be met for the transfer pump to shut off automatically (AUTO position)?
A float switch in the mid tank sends a signal indicating the tank is almost empty and a pressure switch located in the transfer line sends a signal when the pressure in the lines drops below 5+-0.5 psi
51
What switch controls the transfer pumps?
FUEL TRANS switch located on the lower portion of the overhead panel
52
How does the primary jet pump operate?
It provides fuel under pressure from the fuel feel chamber through the fuel feed line; requires motive flow from the engine driven fuel pump; also provides motive flow for the aft transfer pump
53
What controls the motive flow valves?
JET PUMP switches
54
What does the forward transfer jet pump receive motive flow from?
the boost pump
55
What does the aft transfer jet pump receive motive flow from?
