Ch 7 - Normal Procedures Flashcards
How do you know your regulator is faulty during checks with supply lever off
Ability to breathe
Required APU warmup and cooldown times before/after applying a bleed air load.
1 minute
RAD ALT - Precision approach setting
50 feet below HAT (not always 150)
RAD ALT - Circling/Visual approach
300 feet
RAD ALT - Non-Precision approach
250 feet
What is Mode C (Military Mode 3)
Refers to aircraft equipped with an altitude encoder and altimeter. With Mode C, ATC will actually see the flight level altitude (pressure altitude) on their radar screen if the transponder is operating in the Mode C or “ALT” (altitude) Mode. ATC receives it at 29.92 and their computer applies the current altimeter setting.
What is Military Mode 1
Provides 2-digit 5-bit mission code (cockpit selectable)
What is Military Mode 2
Provides 4-digit octal unit code (set on ground for fighters, can be changed in flight by transport aircraft)
What is Military Mode 4
Provides a 3-pulse reply, delay is based on the encrypted challenge
What is Mode S
Provides multiple information formats to a selective interrogation. Each aircraft is assigned a fixed 24-bit address. TCAS compatible. Mode S provides improved surveillance quality, discrete aircraft addressing function, and digital capability.
APU may shut down without an associated ACAWS message. What would you do?
Maintenance is required prior to APU restart
Why do we start all engines in LSGI.
A more gradual heating of engine components, although HSGI can still be used if needed.
On the ground, if fuel has been sprayed into the engine without ignition,
motor the engine for at least _____ seconds with the engine start switch in the
_____ position. On subsequent start, it is acceptable to have flames out the tailpipe for a few seconds due to residual fuel.
30, motor
The engine can be started with the propeller at any blade angle. The typical
time from starter activation until NP is on speed is _____ seconds. Allow up to
two minutes after NG is on speed for onset of propeller rotation. Fuel flow
is indicated at approximately _____ percent NG.
30 sec, 40%
If a start is not successful, the FADEC will shut fuel off after _____ seconds from starter switch activation. If
an automatic shutdown occurs, place the ENGINE START switch to _____
and allow NG to decrease to zero then wait _____ seconds before attempting a
restart.
70 sec, STOP, 30 seconds
