Sample Module 13 Avionics Systems Practice Questions

Try these sample questions to review concepts for the Module 13 Avionics Systems exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1What is the primary operational function of an automatic Yaw Damper system on a jet transport aircraft?
A.To damp aerodynamic Dutch roll oscillations without causing rudder pedal movement in the cockpit
B.To control the pitch attitude of the aircraft during automatic flare and touchdown
C.To maintain a constant Mach number during high-altitude cruise flight
D.To automatically trim the elevator surfaces during asymmetrical engine thrust conditions
Explanation: The yaw damper system automatically applies rudder displacement to suppress Dutch roll (a coupled out-of-phase roll and yaw oscillation characteristic of swept-wing aircraft) without moving the cockpit rudder pedals.
2Which frequency band is allocated internationally for civilian aeronautical VHF voice communications?
A.118.000 MHz to 136.975 MHz
B.108.000 MHz to 117.950 MHz
C.2.000 MHz to 29.999 MHz
D.960.000 MHz to 1215.000 MHz
Explanation: Civilian aeronautical VHF communications operate in the Very High Frequency band between 118.000 MHz and 136.975 MHz using Amplitude Modulation (AM).
3What frequency range is utilized by airborne High Frequency (HF) communication transceivers?
A.2 MHz to 30 MHz
B.118 MHz to 137 MHz
C.225 MHz to 400 MHz
D.1.5 GHz to 1.6 GHz
Explanation: Airborne HF transceivers operate in the High Frequency spectrum between 2 MHz and 30 MHz (2.000 to 29.999 MHz), using ionospheric skywave refraction for long-range beyond-line-of-sight communication.
4What primary navigation information is provided to the flight deck by a Very High Frequency Omnidirectional Range (VOR) receiver?
A.Magnetic bearing/azimuth of the aircraft relative to the selected VOR ground station
B.Slant-range distance in nautical miles from the aircraft to the ground transponder
C.Direct vertical deviation from a 3-degree glide slope path
D.Exact ground speed and wind velocity component
Explanation: The VOR system provides magnetic bearing (radials) from the ground station to the aircraft by measuring the phase difference between a 30 Hz reference phase signal and a 30 Hz variable phase signal.
5At what carrier frequency do all Instrument Landing System (ILS) Marker Beacons operate?
A.75 MHz
B.108.10 MHz
C.329.15 MHz
D.960 MHz
Explanation: All ILS Marker Beacons (Outer, Middle, and Inner markers) operate on a single fixed frequency of 75 MHz VHF.
6What cockpit indication and audio tone identify passage over an ILS Outer Marker (OM)?
A.Blue light flashing with a 400 Hz dash sequence
B.Amber light flashing with a 1300 Hz alternate dot/dash sequence
C.White light flashing with a 3000 Hz dot sequence
D.Green light flashing with a continuous 1000 Hz tone
Explanation: The ILS Outer Marker (OM) triggers a blue cockpit indicator lamp accompanied by a 400 Hz audio tone modulated into a continuous series of dashes (2 per second).
7What cockpit indication and audio tone identify passage over an ILS Middle Marker (MM)?
A.Amber light flashing with a 1300 Hz alternate dot/dash sequence
B.Blue light flashing with a 400 Hz dash sequence
C.White light flashing with a 3000 Hz dot sequence
D.Red light flashing with a 800 Hz continuous tone
Explanation: The Middle Marker (MM) illuminates an amber indicator light on the flight deck and generates a 1300 Hz tone with alternating dots and dashes.
8Which frequency band is assigned to ILS Localizer ground transmitters?
A.108.10 MHz to 111.95 MHz on odd-tenth MHz channels
B.108.00 MHz to 117.95 MHz on even-tenth MHz channels
C.329.15 MHz to 335.00 MHz
D.118.00 MHz to 136.95 MHz
Explanation: ILS Localizer signals are allocated forty channels between 108.10 MHz and 111.95 MHz using odd tenths of a megahertz (e.g., 108.10, 108.15, 108.30 MHz).
9What is the frequency band used by an ILS Glide Path (Glideslope) system?
A.329.15 MHz to 335.00 MHz (UHF)
B.108.10 MHz to 111.95 MHz (VHF)
C.75.00 MHz (VHF)
D.5000 MHz to 5250 MHz (SHF)
Explanation: The ILS Glide Path operates in the Ultra High Frequency (UHF) spectrum between 329.15 MHz and 335.00 MHz across 40 paired channels.
10Distance Measuring Equipment (DME) operates in which international frequency band?
A.960 MHz to 1215 MHz (UHF)
B.108.00 MHz to 117.95 MHz (VHF)
C.4.2 GHz to 4.4 GHz (SHF)
D.1575.42 MHz (L-band)
Explanation: DME operates in the UHF frequency band between 960 MHz and 1215 MHz, using pulse-pair interrogation and reply techniques.
