Question 1

What is the function of the Horizontal Situation Indicator (HSI)?

Accepted Answer

Combines heading information with VOR/ILS course deviation on one display

Answer

The HSI integrates a gyroscopic directional gyro with VOR or ILS navigation data, giving the pilot heading and course deviation on a single instrument.

Question 2

What does an ILS (Instrument Landing System) consist of?

Accepted Answer

A localizer for lateral guidance and a glideslope for vertical guidance

Answer

An ILS provides precision approach guidance using a localizer (lateral) and glideslope (vertical) beam, usually supplemented by marker beacons.

Question 3

What is the purpose of the Transponder Mode C?

Accepted Answer

Automatically transmits aircraft altitude along with the squawk code to ATC radar

Answer

Mode C transponders encode the aircraft's pressure altitude and transmit it automatically with each reply, allowing ATC to see altitude on their radar displays.

Question 4

What is dead reckoning in aviation navigation?

Accepted Answer

Estimating current position using a known past position, heading, speed, and elapsed time

Answer

Dead reckoning calculates the estimated present position from a last known fix by applying known heading, airspeed, wind correction, and time elapsed.

Question 5

What does RNAV stand for and what capability does it provide?

Accepted Answer

Area Navigation; it allows aircraft to fly any desired route within coverage of navigation aids

Answer

RNAV (Area Navigation) enables aircraft to navigate along any desired path within the coverage of ground-based or satellite navigation signals, not just radials from stations.
