RTR 3 : Radar

Correct answer is A – Radio Detection And Ranging

Correct answer is B – By measuring the time delay between sending the pulse and receiving the echo

Correct answer is B – Detecting and tracking aircraft and vehicles on airport runways and taxiways

Correct answer is A – MSSR uses transponder replies to provide aircraft identity and altitude, while PSR detects all reflected signals

Correct answer is A – L band (1–2 GHz)

Correct answer is B – To detect objects and measure their distance

Correct answer is B – Listening for signals that bounce back from objects

Correct answer is B – Vehicles and aircraft on the ground at airports

Correct answer is B – Monopulse Secondary Surveillance Radar (MSSR)

Correct answer is B – Change in frequency of the reflected waves

Correct answer is – Secondary radar principle

Correct answer is – Slant range distance

Correct answer is – 960–1215 MHz

Correct answer is – VOR and ILS

Correct answer is – Distance and bearing

Correct answer is – Secondary radar receives a reply from the target’s transponder

Correct answer is – It shows the aircraft’s height in nautical miles

Correct answer is – 199 NM

Correct answer is – Distance measuring equipment

Correct answer is – To receive interrogation pulses and send a reply

Correct answer is – The straight-line distance between aircraft and station, including altitude

Correct answer is – Every 30 seconds

Correct answer is – Because it includes altitude as well as horizontal distance

Correct answer is – R = (T – 50) / 12.359

Correct answer is – 50 microseconds

Correct answer is – Very accurate slant range data for position fixing
