Question 1

What is the purpose of the Marker Beacon receiver in an ILS approach system?

Accepted Answer

Identifies specific distance fixes along the approach path

Answer

Marker beacons (outer, middle, inner) transmit upward-directed 75 MHz signals that identify specific distance points along the ILS approach path.

Question 2

In a Weather Radar system, what does the color red typically represent on the display?

Accepted Answer

Heavy precipitation, avoidance recommended

Answer

In standard weather radar color coding, red indicates heavy precipitation with potential turbulence, and pilots are advised to avoid these areas.

Question 3

What navigation system uses the time difference of arrival (TDOA) of signals from multiple ground stations?

Accepted Answer

LORAN-C

Answer

LORAN-C determines position by measuring the time difference of arrival of pulsed signals from a chain of synchronized ground transmitters.

Question 4

What is the function of the flight management system (FMS) VNAV mode?

Accepted Answer

Manages vertical profile including climbs, descents, and speed

Answer

VNAV (Vertical Navigation) manages the aircraft's vertical flight profile, including climb/descent rates, crossing altitudes, and speed targets to meet flight plan constraints.

Question 5

A TCAS II system issues a Resolution Advisory (RA). What must the flight crew do?

Accepted Answer

Follow the RA maneuver immediately regardless of ATC instructions

Answer

FAA regulations and ICAO standards require crews to follow TCAS II Resolution Advisories immediately, as the system coordinates escape maneuvers between conflicting aircraft.
