ASE423 unit 4 Quiz

The Instrument Landing System (ILS) primarily assists pilots during:

• Cruise flight

• Take-off

• Approach and landing

• Taxiing

The localizer component of the ILS provides information about:

• Vertical descent path

• Lateral runway alignment

• Aircraft altitude

• Engine performance

The glide path transmitter in ILS operates typically in the frequency range of:

• 108–112 MHz

• 329–335 MHz

• 200–300 MHz

• 400–500 MHz

The main purpose of the ILS marker beacons is to indicate:

• Airspeed

• Distance from runway threshold

• Altitude

• Engine RPM

The outer marker in an ILS system is located approximately:

• 2 km from runway

• 4–7 km from runway

• 10 km from runway

• 500 m from runway

An autopilot system in an aircraft primarily helps in:

• Manual steering

• Automatic control of flight path

• Engine thrust regulation only

• Air traffic communication

The basic components of an autopilot system include:

• Sensors, computers, and actuators

• Only radio antennas

• Hydraulic pump and motors

• Radar and sonar sensors

A three-axis autopilot system controls:

• Roll, pitch, and yaw

• Thrust, lift, and drag

• Pressure, temperature, and speed

• Power, weight, and gravity

The autopilot pitch channel is primarily responsible for controlling:

• Rudder

• Elevator

• Aileron

• Flaps

The roll channel in an autopilot system controls:

• Pitch movement

• Vertical climb

• Bank or lateral balance

• Landing gear
