B747-8 (SECTION 7) EXAM QUESTIONS AND ANSWERS WITH
COMPLETE SOLUTIONS VERIFIED
Which parameters have caution ranges displayed by amber bands?
N1, EGT (max continuous thrust), thrust reverser indication, oil pressure, oil
temperature
What conditions will inhibit the EGT amber colour change?
Inhibited during takeoff or go around for 5 minutes after TOGA pushed
Inhibited for 10 minutes if one engine fails or is shutdown
What are the different EGT red line indications?
takeoff EGT limit or multiple engine in-flight start limit
During Start Ground: Max EGT 750°C
During Start Air: Max EGT 875°C
Max Take-off: Max EGT 1060°C
What indications are displayed above N2 display box and what it indicates?
Start Mode Indication
Running/Autostart/Autorelight
How is engine start completion indicated?
RUNNING at Start Mode Indicator
, When will the Secondary Engine indications be displayed full on Secondary
EICAS?
· When EICAS initially receive electrical power
· Selected using ENG display switch on display panel
· Fuel control switch moved to CUTOFF in flight
List all the Primary and Secondary Engine Parameter and Where are they
displayed?
Primary: N1, EGT
Secondary: N2 RPM, Fuel Flow, Oil Temp, Oil Pressure, Oil Quantity, Vibration
Will there be indication if EGT reaches Maximum Continuous limit?
EGT indicator changes colour to amber
When will an engine digital indicator box turn red? Can it be cancelled?
Yes - push CANC / RCL
Turns red when parameter reaches operating limits.
Changes back to white when parameter returns to normal operating range. Box
enclosing digital indicator remains red as a reminder of exceedance.
What does the amber line on the N1 indicator represent?
Maximum N1
When will Partial Display of the secondary engine parameters be presented? How
can the display return to normal?
