AVIT 325 BLOCK 3 EXAM QUESTIONS WITH ACCURATE
ANSWERS
3 Methods of cooling correct answer Fuel, Oil, Air
3 Negative Effects of Hot Engine correct answer Impairs Lubrication
Weakens/Shortens life of parts
Hot oil thinner, less pressure, reduced quality
3 Ways to trouble shoot landing gear correct answer Cycle gear
Shake Plane - if ice and such accumulates, to shake off, gentle rock
Visual Inspection, check mirror, ask tower
Checklists
5 Components of governor correct answer Control Linkage - prop lever, adjusts
tension to speeder string
Speeder Springs - above flyweights, sets mutual position of flyweights, sets RPM
Fly-Weights - Spins at prop RPM, Increase in RPM will spin faster, changing
centrifugal force
Pilot Valve - Up or down depending on flyweights, centrifugal force
Oil Pump - facilitates movement of oil
,Abnormal ways to DC autopilot correct answer Pull pitch trim/ap circuit breaker
Stall warning
ACM found on
VCM found on correct answer ACM - Larger Aircraft
VCM - Smaller GA Aircraft, we have on SEMI, Freon
Alternator
How many
How is it driven
Type of volt and current
How many amps on IO and Carb
Protected how many amp circuit breaker correct answer 2 Alternators
Engine Belt Driven
28 Volt AC
65 Amps IO, 80 Amps Carb
17 80 amp CB
Alternator Control Unit
Regulates voltage by doing what
When does the voltage relay shut off correct answer Lowsharing, taking electricity
draw and splitting evenly
Above 32 Volts
,Altitude Engine correct answer A reciprocating aircraft engine having a rated
takeoff power that is producible from sea level to an established higher altitude.
Anti servo on rudder moves in correct answer Same direction
Anti-Ice vs De-Ice correct answer Anti - prevention
Deice - Once ice accumulates. About inch and quarter, protective surfaces
APR Modes correct answer Captures and tracks both CDI and vertical guidance if
available.
AP operates at higher sensitivity as well.
ONLY USE AFTER CLEARED FOR APPROACH
Ashless Dispersant correct answer Similar to mineral oil, but collects debris and
brings to oil filter
Automatic Autopilot occurrences correct answer Internal AP Fail
AHRS fail
ADC fail
Inability to compute default modes
Autopilot max fuel imbalance. Where may this also occur correct answer 10
gallons
Takeoff or descent due to awkward attitude
, Autopilot: what comes with
PFD
MFD
Lat Modes
CWS correct answer PDF-
Score box
FD
Command bars
MFD-
Afcs buttons
LAT modes-
Vert Modes
AP settings
CWS-
Temporarily Disengages Autopilot
Aux pump used for correct answer Emergencies and Engine Start
Baffles do what? correct answer Direct airflow to back of engine compartment
