Q

EEC NORMAL MODE

A

Compares commanded N1 to actual N1 and adjusts fuel flow to change engine speed until actual N1 is the same as commanded N1.Over speed, Over temp, Over boost protection when thrust levers fully forward

Q

What gauges have operating Limits?

A

N1, EGT, N2, Oil press & Oil temp have operating limits indicated by red lines, If one of these indications reaches the red line the digital readout, box and pointer all change colour to RED.

Q

What does N1 limit do?

A

Indicated by an Amber line on the dial but does not change colour when max N1 is reached.

18
Q

What is the Derate for Takeoff 1 & 2?

A

Takeoff 1 (300)- 95%. (300ER,F)- 90%Takeoff 2 (300)-85%. (300ER,F)- 80%

19
Q

When will Derates thrust remain until?

A

ABV 10,000ft Derates thrust gradually changes to reach full CLB thrust by:300-12,000ft the 1 or 2 annunciation disappears from the display by 12,500ft300ER,F- 30,000ft. The 1 annunciation disappears by 30,500ft The 2 annunciation remains until either flaps are extended or GA

20
Q

What are the engines covered for by the EEC in normal mode?

A

N1, N2 protection but no EGT protection.

21
Q

EEC Soft mode

A

Auto switches to this mode when switches in NORM. Thrust will be fixed and will not change.

22
Q

Hard Alternate mode

A

ALTN is manually selected on the EEC mode switch. Reference and target N1 and maximum commanded N1 values are displayed on the N1 indication.

23
Q

What protection is provided in the ALTN modes

A

Thrust protection not provided and maximum rated thrust is reached at a thrust lever position less than full forward. As a result thrust overboost can occur at full forward thrust lever positions.N1,N2 redline protection is still available in the ALTN control mode.

24
Q

What are the two idle speeds and when are they selected

A

Minimum Idle: lower thrust setting used for for ground ops and all stages of flight except approach & landing.Approach Idle: selected whenever the higher idle setting is required for proper system operation.EEC AUTOMATICALLY SELECTS IDLE SPEEDS

25
Q

What is displayed on the EGT during start

A

Maximum start line limit, displayed until engine is stable

26
Q

Starter duty cycle

A

Five minutes on, followed by one- half minute off per minute on.

27
Q

When does the in flight start envelope display on the primary display and what does it indicate?

A

ENG is not running in flightRespective Fire SW not pulledBoth EICAS prim & sec are selectedDisplays closest starting FL and two descending FL’s at 2000ft intervals.

28
Q

Auto relight?

A

In air or on ground, automatic relight feature is enabled if N2 drops below idle SPD.EEC energizes both ignition systems.

29
Q

When do the Engine and Spar valves open?

A

When the fuel CONT switch is in the RUN position and the ENG fire SW is in.

30
Q

Where is fuel flow measured from?

A

After passing through the engine fuel valve.

31
Q

Where is the oil temp measured from?

A

After leaving the scavenge pump, prior to entering the second filter.

32
Q

Is there a minimum oil quantity limit?

A

There’s is no min oil quantity limit, (no amber or red line)

33
Q

What happens when the reverses are pulled aft to the interlock position?

A

A/T disengagesAuto speed brakes deploy

34
Q

Is oil quantity displayed in litres or quarts?

A

Quarts

35
Q

When should the engine start selector move from GND to AUTO during an engine start?

A

50% N2

36
Q

With the ENG start selectors in AUTO when will the selected igniters continuously operate?

A

With slats extended or ENG anti ice on

37
Q

Is there a time limit to continuous ignition or flight ignition?

A

No time limit

38
Q

What is the purpose of selecting FLT on the ENG start selectors following a loss of dual engine failure?

A

FADEC- Auto relight which will operate both igniters when N2 drops below idle speed.

39
Q

When is the red EGT start limit line of 750degrees displayed when on the ground?

A

Fuel control SW is in cut off position, remains displayed when fuel CONT SW is moved to RUN until the engine is stabilised at idle (FADEC- 10sec after N2 reaches 60%) (NON-FADEC- 5 sec after N2 reaches 60%)

40
Q

What happens when the Fuel CONT SW is positioned to RUN?

A

Opens ENG & SPAR valvesActivates selected igniters

41
Q

Can autothrottle sill remain engaged in EEC hard and soft modes?

A

Yes

42
Q

What does pulling up the reversers do?

A

Disengages AutothrottleDeploys speed brakes if in down position
