0238057 · Holding, Radial Intercept, and Bearing to Plot
The true bearing (QTE) from a station is 320 degrees in the Southern Hemisphere (SH). The Conversion Angle (CA) is 8 degrees., find the Bearing to Plot (BTP) on a Mercator Chart.
- A312 degrees
- B328 degrees
- C320 degrees
Why that is the answer
Radio bearings are **great-circle (GC)** bearings, because radio waves follow the shortest path over the earth. On a **Mercator** chart a straight line is a **rhumb line (RL)**, a line that keeps a constant direction. To draw the bearing as a straight line you must change it by the **conversion angle (CA)**, the angle between the GC and the RL at the place where the bearing was measured.
Which way? Look at the diagram: the GC always bends towards the **nearer pole** compared with the RL. So at its start, the GC points a little more towards that pole than the RL does.
Here we are in the **southern** hemisphere, so the GC bends towards the South Pole. The line leaves the station on 320° (north-west). The GC leaves pointing a little more towards south than the RL. From 320°, turning towards south means a smaller number (towards 270°). So the GC (320°) is the smaller one and the RL is larger by the CA: 320° + 8° = **328°**.
So plot **328°** from the station.

Frequently asked
How many Holding, Radial Intercept, and Bearing to Plot questions are there for the DGCA CPL Air Navigation paper?
Avielevate's bank carries 32 published Holding, Radial Intercept, and Bearing to Plot 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 Holding, Radial Intercept, and Bearing to Plot?
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 Holding, Radial Intercept, and Bearing to Plot?
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.
