- AControl region
- BControl zone
- CControl area
Why that is the answer
**CTR** means **control zone**. It is controlled airspace extending upward **from the surface** around an aerodrome, to protect aircraft arriving and departing.

Chapter 02 of the Radio Telephony paper. 30 practice questions in the Avielevate bank, every one with its answer key, filterable into a timed set on this chapter alone.
The learning objectives we file Aeronautical 'Q' Code Signals and Abbreviations questions under, and how many sit behind each. These come straight out of the bank and are regenerated whenever it changes — they are what is there today, not a claim.

Real questions from this chapter, with the answer marked and the reasoning written out — the same explanations you get inside the app.
**CTR** means **control zone**. It is controlled airspace extending upward **from the surface** around an aerodrome, to protect aircraft arriving and departing.
**QNE** asks: **"What indication will my altimeter give on landing at … (place) at … hours, with my sub-scale set to 1013.2 hPa (29.92 inches)?"** In other words, QNE is the **pressure altitude** of the aerodrome — what the altimeter shows on the ground when set to standard pressure.
**QNH** is the **altimeter sub-scale setting that makes the altimeter read the aerodrome elevation when on the ground**. In the air, with QNH set, the altimeter shows altitude above mean sea level.
Avielevate is in an open testing period — nobody is being charged. Create an account, fill in the short form on the pricing page, and we switch on three months of full access: the whole bank, timed mock exams, explanations and weak-topic analytics.
Avielevate is a preparation tool. Always study alongside the official DGCA publications and the approved reference material for your course.
Avielevate's bank carries 30 published Aeronautical 'Q' Code Signals and Abbreviations questions for Radio Telephony, mapped across 1 learning objective. Every one has its answer key, and explanations are being written across the whole bank.
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.
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.
One account covers every chapter of every paper.
