ENGINES AND APU Flashcards
- When does the EICAS automatically show compacted engine display?
- EICAS displays engine indications in compact format whenever:
Secondary engine display is automatically selected, and the lower multifunction display is failed, unpowered, or is occupied, or
Secondary engine display is manually selected to the lower center MFD and the lower MFD is failed, unpowered, or occupied with EICAS
- (200A/B) Describe engine indications and limitations when ECC operate in the soft alternate mode.
2.
EPR indication is blank.
Thrust limit protection is not available.
No reference/target indications are displayed.
Overspeed protection is available.
Autothrottle remains engaged.
- (200A/B) Describe engine indications and limitations when EEC operate in the hard alternate mode.
- EPR indication is blank.
Thrust limit protection is not available.
Reference/target N1 is displayed.
Overspeed protection is available.
Autothrottle remains engaged.
- The EEC selects minimum or approach idle automatically. In flight, when is Approach idle selected?
- Engine anti-ice is operating.
Flaps are commanded to 25 or greater for a two engine approach.
One hydraulic system air-driven demand pump is inoperative, and the flaps are out of the UP position.
The opposite engine bleed valve is closed.
- During an autostart, what indication does the EEC monitor until idle RPM is reached?
5.
EGT
N2
Other engine parameters
- (200 A/B/) On the ground, autostart can make two attempts to start an engine. Under what conditions will the autostart system only make one start attempt?
6.
No N1 rotation
Insufficient air pressure
Starter shaft failure
Start time exceeding starter duty cycle.
- Operation of the EECs in the normal mode maximum thrust is available from the engines. What indicates maximum thrust? 200 A/B ____. 200C/322 ____.
7.
(200A/B) An amber line at the top of the EPR dial
(200C/322) An amber line at the top of the N1 dial
- Each engine has two ignitors. How are ignitors operated during a ground start and during an inflight start?
8.
The EEC automatically selects the appropriate ignitor(s) and alternates ignitors for successive ground starts
Both ignitors are utilized for all inflight start attempts.
- With the FUEL CONTROL switch in RUN, continuous ignition is selected in what configurations?
9.
START/IGNITION selector CON.
START/IGNITION selector NORM and one or both of the following:
Flap lever out of UP position
Engine anti-ice on (automatically or manually selected)
During auto-relight flameout protection
- What controls operate spar and engine fuel valves?
10.
FUEL CONTROL switch
Engine fire handle
- Each engine has two oil filters installed in series. (200 A/B) Which filter can be bypassed?
- The primary oil filter
- Oil quantity is displayed to the nearest quart. What is the minimum oil quantity limit?
- There is no minimum oil quantity limit (no amber or red line limit): however, a low oil quantity causes automatic display of the secondary engine display and reverses the display indication to show black numbers on a white background.
- What occurs when the thrust reverser levers are raised to the interlock position?
13.
Autothrottles disengage.
Autospeed brakes deploy.
- The engine vibration monitoring system can display a range from 0.0 to 5.0. What will cause the secondary engine indications to automatically display?
- There is no certified vibration limit, but when a high vibration level is reached, the secondary engine parameters are automatically displayed.
- What engine failure warning indications occur with an engine failure (actual thrust is less than commanded thrust) during takeoff with airspeed between 65 knots and 6 knots prior to V1?
15.
An aural alert
“Engine Fail” Master Warning Light
PFD ENG FAIL message
