Sample Air Navigation questions
A few questions from the bank, with the answer and explanation under each.
1. True heading 090°, variation 5°W. Magnetic heading is:
- 085°
- 090°
- 095°
- 100°
Show answer
Correct answer: C. 095°
MH = TH + West variation = 090° + 5° = 095°. (TVMDC rule: East is least, West is best)
2. To move the CG aft within limits, a pilot could:
- Add weight to the nose baggage compartment
- Move passengers from front seats to rear seats
- Reduce fuel load only
- Increase takeoff power
Show answer
Correct answer: B. Move passengers from front seats to rear seats
Moving mass rearward shifts the CG aft. Moving passengers from the front to the rear seats increases the total aft moment, moving CG rearward.
3. The purpose of the fuel flowmeter in a piston aircraft is to:
- Measure fuel quantity in each tank
- Indicate fuel consumption rate to allow fuel management and cross-check tank contents
- Control the mixture automatically
- Trigger the fuel pump warning
Show answer
Correct answer: B. Indicate fuel consumption rate to allow fuel management and cross-check tank contents
The fuel flowmeter shows instantaneous fuel burn rate (litres/hour or lb/hr). Used with fuel quantity gauges, it allows pilots to predict remaining endurance and detect abnormal consumption.
4. By what amount must you change your rate of descent given a 10-knot increase in headwind on a 3° glide slope?
- 50 ft/min increase
- 30 ft/min increase
- 50 ft/min decrease
- 30 ft/min decrease
Show answer
Correct answer: C. 50 ft/min decrease
On a 3° glide slope, for every 1 knot change in ground speed, ROD changes by about 5 ft/min (100 ft per NM × 3°/60 min at 1 knot ≈ 5 ft/min). A 10-knot headwind increase REDUCES ground speed by 10 knots, so ROD must DECREASE by 10 × 5 = 50 ft/min to remain on slope.
5. When it is 0600 Standard Time in Queensland, Australia, what is the Standard Time in Hawaii, USA? (Disregard Summer Time)
- 0200 ST
- 0600 ST
- 1000 ST
- 1200 ST
Show answer
Correct answer: C. 1000 ST
As always, use a table: Standard Time at Queensland Today 00 ST STD (long. east, UTC least) - -10 00 - UTC Yesterday 00 UTC STD (long. west, UTC best) - -10 00 - Standard Time at Hawaii Yesterday 1000 00 ST Hour Minute Time Day

The Air Navigation bank currently holds 958 questions. Each has one marked correct answer, and an explanation where one has been written. They are split across 17 chapter question pages so you can practise one topic at a time.
Is the Air Navigation question bank free?
Yes. The questions, answers and explanations are free to read and practise, and you do not need to sign up. Signing in only adds saved progress and attempt history on your dashboard.
What is the DGCA Navigation paper format?
The DGCA Navigation paper is 100 questions in 3 hours, passed at 70%, with no negative marking. The DGCA Navigation paper pools Air Navigation, Radio Navigation and Instrumentation into one paper, so prepare all three together.
How do you know the answers are correct?
Every answer is checked against an authoritative reference, such as a standard ATPL textbook, an ICAO Annex or the relevant DGCA regulation, before it is published. Anything that cannot be verified is flagged or removed rather than guessed.
