NATS STAGE 3 QUESTIONS WITH ANSWERS 2026 |
027
What is VOR? - Answers - Very High Frequency Omni-directional Range.
- short range radio navigation system for aircraft, enabling aircraft with a receiving unit
to determine position and stay on course by receiving radio signals transmitted by a
network of fixed ground radio beacons
How does VOR function? - Answers - Reference signal, directional signal
Radial *(degrees) and phase difference *
What is the definition of radar? - Answers - Radio detection and ranging
What is NATS motto? - Answers - Advancing aviation and keeping the sky safe
What are the 2 types of radar - Answers - primary radar and secondary radar
Explain the difference between primary and secondary radar - Answers - + Primary
radar measures the bearing and distance of targets using the detected reflections of
radio signals
+ secondary radar (or SSR- secondary surveillance radar) relies on targets equipped
with a radar transponder, that reply on each interrogation signal by transmitting encoded
data such as ID code, altitude and further info dependent on chosen mode
Explain mode A,C,S - Answers - - Mode A= transmits ID code only
- Mode c= enables ATCOS to see aircraft altitude or flight level automatically
- Mode S = altitude capability and also permits data exchange (more advanced
communication ) (Altitude and ID)
Name some Advantaged of using mode S - Answers - - Replies not all at once from
aircrafts in area
- Specific aircraft at a time
- More accurate positioning
- Expanded data unit for aircraft to send more information (speed and heading)
what are the two types of radar? - Answers -
