Chapter 6.70 - Engine Flashcards
When will approach idle be selected in flight?
- If flaps are in landing configuration, or
- Engine anti-ice is ON
How is the soft alternate mode of the EEC selected?
Hard alternate mode?
Automatically when normal EEC mode fails
- By either retarding the thrust lever to idle while in the soft alternate mode, or
- Manually selecting ALTN with the EEC switch
How do the soft alternate and hard alternate modes of the EEC differ?
- Soft alternate mode uses the last valid flight conditions and may experience errors as conditions change
- Hard alternate mode reverts the EEC to the alternate mode thrust schedule
What powers the left ignitors?
The right ignitors?
The respective AC transfer bus
AC standby bus
With the engine start switches in CONT which ignitors will be used?
With the switch in FLT?
In CONT the selected ignitors will be used
In FLT both ignitors will be used regardless of which have been selected
What causes an amber REVERSER light to illuminate?
An illuminated REVERSER light will cause the MASTER CAUTION and ENG annunciator lights after how many seconds?
- Isolation or control valve not in commanded position
- One or more thrust reverser sleeves are not in commanded state
- Auto-restow is under way (occurs after every reverse application)
- A failure has been detected in synchronization shaft lock circuitry
12 seconds
What causes an amber ENGINE CONTROL light to illuminate?
Engine control system has a fault, light operates when;
- Engine is operating, and
- Aircraft is on the ground, and
- Below 80 knots prior to takeoff, or
- Approximately 30 seconds after touchdown
When will the secondary engine indications be displayed on the lower display unit?
- When the common display system initially receives power
- When selected by the multi-function display
- In flight when an engine start lever is moved to CUTOFF
- In flight when an engine fails
- When a secondary engine parameter has been exceeded
