0236054 · Very High Frequency Omni Direction Radio Range
An aircraft is flying a true track of 090° towards a VOR near the equator, where the variation is 15°E. The variation at the aircraft is 8°E. Which radial is the aircraft on?
- A075 degrees
- B285 degrees
- C255 degrees
Why that is the answer
A VOR **radial** is the magnetic bearing FROM the station, measured with the **variation at the VOR**. Look at the diagram.
**Step 1, true bearing from the VOR.** The aircraft is flying towards the VOR on 090°(T), so it is coming from the west and is west of the station. The bearing from the VOR to the aircraft is the opposite direction: 090° + 180° = 270°(T). Near the equator the meridians are almost parallel, so this reverse bearing needs no correction for convergence (the meridians closing together towards the poles).
**Step 2, convert to magnetic with the VOR's variation.** East variation is subtracted: 270° − 15° = 255°(M).
The aircraft is on the **255° radial**.
**Tip:** flying TO a VOR, the radial you are on is behind you: track ± 180°.

Frequently asked
How many Very High Frequency Omni Direction Radio Range questions are there for the DGCA CPL Air Navigation paper?
Avielevate's bank carries 35 published Very High Frequency Omni Direction Radio Range questions for Air Navigation, mapped across 1 learning objective. Every one has its answer key, and explanations are being written across the whole bank.
How much of the Air Navigation paper is Very High Frequency Omni Direction Radio Range?
The DGCA does not publish a per-chapter breakdown of its papers, so nobody can honestly tell you — and we will not guess. What we can tell you is what students who have just sat a paper reported meeting, which is measured rather than rumoured: that is the exam recall report inside the app.
What is the best way to revise Very High Frequency Omni Direction Radio Range?
Sit a short timed set on this chapter alone, tag how sure you were of each answer, then drill the two that actually leak marks: the ones you got right while guessing, and the ones you got wrong while confident. Avielevate does that tagging for you and puts anything you got wrong back in front of you on a spaced schedule.
