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
What is the minimum bleed air pressure for sustaining a start?
22 PSI, but a momentary drop below when the starter valve opens is acceptable
Before attempting ground restarts, wait _____ seconds after NG reaches zero (0) to enable a successful test of the ________________________
30 sec, NG independent over-speed protection
circuit.
The ENGINE START switch can be moved from _____ to _____ after an
aborted start before NG reaches zero. The FIRE handle shall be ___ to allow
the MOTOR operation.
STOP to MOTOR, IN
1 of 2 engine shutdown categories: For all ACAWS Warnings (red master warning light and tone), during start you should
Pull the FIRE handle and then place the ENGINE START switch to STOP.
2 of 2 engine shutdown categories: For all other engine shutdowns on the ground, including normal shutdowns and shutdowns for ACAWS Cautions and Advisories, _________________________. Although pulling the engine FIRE handle on the
ground does not damage equipment, it does cycle numerous valves and the
auxiliary feather pump.
Place the ENGINE START switch to STOP
If any of the following Warnings occur, pull the engine FIRE handle and place the ENGINE START
switch to STOP:
(1) ENG 1 (2, 3, or 4) FIRE.
(2) ENG 1 (2, 3, or 4) MGT HI.
(3) START VLV 1 (2, 3, or 4) OPEN.
(4) Visible indications of a fire.
(5) Visible fluid leak.
If any of the following conditions are observed, discontinue the start by placing the ENGINE START
switch to STOP:
(1) No NG within 10 seconds after actuation of the ENGINE START switch to START.
(2) No indication of oil pressure within 15 seconds of NG rotation (ENG 1 (2, 3, or 4) NO OIL PRESS
ACAWS Caution).
(3) No indication of oil pressure within 15 seconds of NP rotation (GEARBOX 1 (2, 3, or 4) NO OIL
PRESS ACAWS Caution).
(4) ENG 1 (2, 3, or 4) FLAMEOUT ACAWS Caution, ENG 1 (2, 3, or 4) NO LIGHTOFF ACAWS
Advisory and ENG 1 (2, 3, or 4) STAGNATED START ACAWS Advisory. (The FADEC
automatically aborts the start for these, but still place the ENGINE START switch to STOP.)
Normal hydraulic system operating pressure should be indicated within _____
seconds after the propeller is on speed. If the control column is in the full
forward position this pressure may not be reached because of internal bypass
of fluid in the elevator boost package. Pulling the control column off its stop
___ to ___ inches will eliminate this bypass.
30 sec, 2-3 inches
If OAT is above _____ and the wing/empennage anti-ice test must be repeated, wait at least _____ minutes before repeating test to prevent overheating the _____
70 °F (21 °C), 10 min, Vertical tail
