AET PHASE 3 COMMS TEST STUDY GUIDE UPDATED
ACTUAL QUESTIONS AND CORRECT ANSWERS
Question:
Flight Management System
Answer:
Processes and displays mission information, monitors and displays equipment
status, and allows for the crew to control and test several systems. Automates
flight tasks and reduces workload of flight crew.
Question:
Flight Management System Advantages and Disadvantages
Answer:
Advantage: reduces workload for crew, minimizes space and weight
Disadvantage: Pilots can be distracted and minimize awareness of
surroundings.
Question:
Control Display Unit
Answer:
Primary input/interface for most CG aircraft systems. Eliminates the need for
separate control panels for every system. Failures are detected during built in
test will be announced on the failure line of component systems status page.
Question:
Multifunction Display (MFD)
Answer:
Device that manages and displays information such as aircraft's flight,
navigations, engine, hull and alarm on a single display screen.
Question:
Flight Managment Computer
Answer:
Uses two computers; cross talk during normal ops. If on fails, second one can
continue w/out loss of system ops. Contains nonvolatile memory that stores
navigation and airport information.
Question:
Engine indication advisories, cautions, and warnings
Answer:
Provides a visual display of the engine performance and other systems
depending on aircraft. Displays any faults or abnormal readings to the flight
crew.
Question:
Flight Control Computer
Answer:
Controls servo-actuators in flight control and auto throttle system. Needed for
fly-by wire operation when there are no physical connections between yoke,
, cyclic, collective, throttles, etc. to flight control surfaces and/or engines.
Question:
Thrust Management Computer
Answer:
Full authority digital engine control. System monitors: revs per minute (RPM),
engine pressure ratio (EPR), engine gas temperature (EGT), and fuel flow (FF).
Automatically sets thrust levers for engine's performance.
Question:
1553 Data Bus
Answer:
Provides data path between aircraft and systems. Controls and displays
information transferred between components.
Question:
Data Bus Coupler
Answer:
Interface between main bus and LRU; isolates components in event of failure.
Question:
Bus Stub
Answer:
Length of bus wire connecting terminal (component) to data bus.
Question:
Bus Terminator
Answer:
Connected to data bus coupler, reduces electrical reflections that can cause
instability, and contains resistor w/ impedance of 78 ohms.
Question:
Data Connector Unit
Answer:
Allows CDU to control non 1553 bus equipment and converts digital to analog
and vice versa.
Question:
Addressing
Answer:
Assures input commands reach the correct terminal. Bus information
delivered to terminals where each terminal has remote terminal address
containing combination of grounded pins called straps.
Question:
Internal Communication Systems
Answer:
the central control/distribution point. It is used to distribute audible
information and communication audio to the aircrew. Allows aircrew to
monitor internal aircraft communication, receive and transmit on comm
radios, receive on NAV radios and audible warning and alarms.
