SimplyATPL › 062 Radio Navigation
Radio Navigation (062) covers radio propagation, ground-based aids such as NDB, VOR, DME and ILS, primary and secondary radar, GNSS and performance-based navigation (PBN), including RNAV and RNP specifications.
Free, no sign-up. The practice paper uses the question count and time limit from CAA guidance for this subject. Check the CAA for the current figures before your exam.
Questions test how each aid works, its range and accuracy, and its errors and limitations. PBN terminology is precise, so learn the definitions exactly.
In the practice desk you can sit a full 66-question paper under exam conditions, or drill one syllabus topic at a time. Questions you miss come back after 1, 3, 7, 16 and 35 days, so weak areas get repeated until they stick.
Every topic below has practice questions, and you can drill any of them on its own.
Five questions from the bank. Each one in the practice desk has a worked explanation like these.
Answer: B. 800 m
Wavelength = speed of light ÷ frequency.
Common trap: Leaving the frequency in kHz or MHz before dividing.
Answer: B. The magnetic bearing from the aircraft to the station
Fly the QDM, with no wind, to reach the station.
Common trap: Confusing QDM (to) with QDR (from).
Answer: B. It gives the best reflection from water droplets and wet hail
Shorter wavelengths reflect more from precipitation but are attenuated more.
Answer: A. Four
There are four unknowns: x, y, z and the receiver clock error.
Common trap: Answering three, ignoring the clock error.
Answer: A. RNP requires on-board performance monitoring and alerting
Common trap: Thinking RNP means "GNSS only".
