CUTOFF:
-Spar Fuel Shutoff Valve and Engine Fuel Shutoff Valves close
-Ignition system de-energizes

(Sec 7.010 p 6)

Question 4

What is required for selection of Reverse Thrust?

Answer 4

forward thrust lever must be at IDLE to select reverse
(below 10 feet RA?)

(Sec 7.010 p 6)

Question 5

What fuel valve(s) close when an engine Start Lever is moved to CUTOFF?

Answer 5

• Spar Fuel Shutoff Valve and Engine Fuel Shutoff Valve close
• Ignition System de-energizes

(Sec 7.010 p 6)

Question 6

What component controls and monitors engine parameters?

Answer 6

Electronic Engine Control (EEC)

Sec 7.010 p 7

Question 7

The Electronic Engine Control (EEC) provides exceedance protection for which parameter(s) in normal mode?

Answer 7

The EEC provides N1 and N2 redline overspeed protection in both normal and alternate modes

(Sec 7.010 p 12)

Question 8

In Normal Mode, what does the Electronic Engine Control (EEC) use to calculate N1 thrust ratings?

Answer 8

Sensed flight conditions and bleed air demand to calculate N1 thrust ratings

(Sec 7.010 p 9)

Question 9

What are the possible EEC modes with the Engine EEC switch showing both the ON (white) and ALTN (amber) displays illuminated?

Answer 9

Automatic switching to Soft Alternate Control Mode

Sec 7.010 p10

Question 10

Compare thrust in EEC HARD ALTERNATE Mode to normal mode for a given thrust level position.

Answer 10

Hard Alternate Control Mode thrust is always equal to or greater than Normal Control Mode for the same lever position

(Sec 7.010 p 11)

Question 11

What does an ENGINE CONTROL (amber) light mean?

Answer 11

EEC detects non-dispatchable faults in the Engine Control System

(Sec 7.010 p 13)

Question 12

What mode is active with the Thrust Mode Display indicating R-TO (green)?

Answer 12

Reduced Takeoff

Sec 7.010 p 21

Question 13

What causes the ENG FAIL Alert (amber) on the EGT indicator?

Answer 13

When respective engine is operating at a condition below sustainable idle (50% N2) and the Engine Start Lever is in the IDLE position

(Sec 7.010 p 25)

Question 14

What removes an ENG FAIL Alert (amber)?

Answer 14

• engine recovers
• Start Lever is moved to CUTOFF, or
• Fire Switch is pulled

(Sec 7.010 p 25)

Question 15

On the ground, after engine shutdown, what does a red box on the EGT Readout indicate?

Answer 15

An in-flight exceedance has occurred

Sec 7.010 p 24

Question 16

What does “reverse video” displayed on the Engine Vibration readout indicate?

Answer 16

Vibrational scalar units exceed 4.0

Sec 7.010 p41

Question 17

What should the ENG VALVE CLOSED lights (blue) and SPAR VALVE CLOSED lights (blue) indicate during a normal preflight, power ON, Engines not running?

Answer 17

dim blue

Sec 7.010 p 28

Question 18

What does an illuminated FILTER BYPASS light (amber) indicate?

Answer 18

impending filter bypass due to a contaminated filter

Sec 7.010 p 29

Question 19

What is the indication if the engine oil pressure drops below redline during takeoff roll (>80)?

Answer 19

Steady “LOW OIL PRESSURE” light on Upper DU (Flashing inhibited 80 kts to 400 RA)

(sec 7.010 p 37)

Question 20

What does the Ignition Selection Switch in the IGN R position select?

Answer 20

IGN R selects the right igniter for use on both engines

Sec 7.010 p 43

Question 21

In flight, what does the Engine Start Switch in CONT provide with the Engine Start Lever in IDLE?

Answer 21

The selected igniters (L R or BOTH) are operated continuously

(Sec 7.010 p 44)

Question 22

In flight, what does the Engine Start Switch in FLT provide with the Engine Start Lever in IDLE?

Answer 22

Both igniters are operated regardless of selected igniters

Sec 7.010 p 44

Question 23

What does a steady START VALVE OPEN (amber) light indicate?

Answer 23

The start valve is open either during engine start or uncommanded between 80 kts and 400 RA — will flash if otherwise uncommanded

(Sec 7.010 p 46)

Question 24

What does an amber REV indicate? A green REV?

Answer 24

Amber REV: reverser sleeve moves from stowed position
Green REV: reverse thrust lever can be raised to detent No 2

(Sec 7.010 p 51)

Question 25

What does a REVERSER (amber) light on the Aft Overhead Panel indicate?

Answer 25

Illuminates for roughly 10 seconds upon reverser stowage until Isolation Valve closes.

After 12 seconds, illuminated REVERSER indicates a malfunction has occurred and Master Caution illuminates

(Sec 7.010 p 53)

Question 26

Which APU lights will accompany an automatic APU shutdown?

Answer 26

MASTER CAUTION and corresponding LOW OIL PRESSURE, FAULT, or OVER SPEED

(Sec 7.020 p 5)
