NAVGN · CPL written paper

The DGCA Air Navigation question bank.

Navigation is the paper that punishes guesswork. This is the whole thing — 7,751 questions across 176 chapters, from the shape of the earth to a full flight plan, with 245 of the 1,847 numericals solved step by step rather than just answer-keyed, and more written every week.

Navigation is one of the two 100-question DGCA papers. That is roughly 1 minute 48 seconds a question, and a meaningful share of them are numericals you cannot do in your head — which is why speed on the standard formulae, not recall, is what actually gets marked.

Before you start

What to know about
Air Navigation.

What the paper testsMethod, not memory

Air Navigation is examined as a working paper. You are given a position, a track, a wind or a chart and asked to produce a number — so knowing that convergency exists is worth nothing if you cannot get to ch.long × sin(mean lat) under time pressure.

The bank is built around that. Questions are grouped by the chapter that generates them, so you can drill one formula until it stops costing you time, then move on.

What is insideA solved numerical is actually solved

A worked numerical here means a formula box with the governing equation on its own, then a numbered method that goes from the given data to the answer. No skipped algebra, no "hence". 245 of the 1,847 navigation numericals carry one today, and the queue is worked down every week.

Where a printed answer key is aeronautically wrong — and several circulating keys are — the solution teaches the correct method and flags the discrepancy instead of quietly repeating the error. That is also why the count is published rather than rounded up to "all of them": a solution written against a key nobody has checked would be worth less than none.

Where marks go missingUnits, signs and mean latitude

The most common losses in this paper are not conceptual. They are minutes read as degrees, an east–west change of longitude signed the wrong way, departure computed at the wrong latitude, and TAS used where groundspeed was wanted.

Because every question carries its chapter, a run of wrong answers tells you which of those it is rather than just that "navigation is weak".

How to work through itChapter, then paper

Take one chapter in practice mode with the working visible until the method is automatic. Switch that chapter to test mode — only test and exam answers move your readiness estimate. Wrong answers land in the mistakes bank on their own.

When several chapters hold, sit a full 100-question paper on the clock. That is the only honest rehearsal for a three-hour sitting.

Inside a question

Not a list.
A worked answer.

Every MCQ is graded the moment you answer it, with the correct option revealed. Where a worked solution exists it shows the reasoning rather than just the letter — 245 of the 1,847 numericals in Air Navigation.

01
Auto-graded, all 7,751
Pick an option and get instant right or wrong with the correct answer revealed — except in exam mode, which reveals nothing until you submit.
02
Formula box first
A solved numerical carries the governing equation on its own line, so you can revise by formula before you revise by question.
03
Numbered method
Worked step by step from the given data to the answer, with nothing skipped.
04
Chapter tagged, all 7,751
Every question carries its chapter and whether it is theory or a numerical, so a wrong answer tells you what to revise.

Air Navigation · Departure Numerical

An aircraft flies from A (60°N 010°W) to B (60°N 020°W). The departure between A and B is:

A300 NM✓

B600 NM

C520 NM

D1,200 NM

Worked solution

Departure (NM) = Change of longitude (minutes) × cos(latitude)

1Change of longitude = 020°W − 010°W = 10° = 600 minutes
2Both positions lie on the 60°N parallel, so latitude = 60°
3Departure = 600 × cos 60° = 600 × 0.5
4= 300 NM — option A

Questions about the questions

Air Navigation FAQ

Is the DGCA Air Navigation question bank really free?

Yes. All 7,751 Air Navigation questions, all 245 worked solutions and every full-length timed paper are open with no paywall, no trial timer and no card. There is no paid tier of the question bank to upgrade to — the video classes AIVR CPL sells are separate and optional.

Does it cover DGCA back questions for Navigation?

Yes. The bank reproduces the previous-year and repeated questions DGCA has set, question for question, with the answer key resolved and the numericals solved. They sit inside the chapter that generates them rather than in a separate "back questions" dump, so you meet them while revising the method.

How long is the DGCA Navigation paper?

The DGCA Air Navigation paper is 100 questions in 3 hours, marked out of 100 with a pass at 70. Exam mode on AIVR CPL is that exact shape, on the clock, with nothing revealed until you submit.

Do the navigation numericals come with formulae?

A solved numerical carries a formula box with the governing equation, then a numbered method from the given data to the answer — so you can revise by formula alone before you revise by question. 245 of the 1,847 navigation numericals are solved that way today; the rest carry the question and the resolved answer key while the solutions are written.

Is this bank for CPL or ATPL navigation?

This is the CPL/General Navigation bank. ATPL General Navigation is examined by DGCA as its own subject and has its own separate bank and its own 100-question paper on AIVR CPL.
