INDIA'S FIRST FREE RTR(A) R/T PRACTICE SIMULATOR

Radio Simulator

The RTR(A) written paper tests what you know. Part 2 tests how you sound — live, on frequency, with an examiner playing ATC. The Radio Simulator puts you on that frequency today: real ICAO phraseology, mandatory read-backs, examiner probes, emergencies, and a gradesheet at the end.

Speak or tap your calls ATC voice with real radio feel Graded to the 50% Part-2 pass mark Every rule cross-linked to the RTR(A) book No two flights the same — airport, weather, callsign & traffic roll fresh
Rolling your flight — weather, callsign, traffic…

New to the simulator? Here's your walkaround

Seven things and you're ready to key the mic. Nothing here bites — mistakes cost points, never progress, and every flight can be flown again.

1 · Pick a scenario and a mode

Start with Scenario 1 in LEARN mode — phrase chips build your calls for you and the radio tunes itself. When the words start coming on their own, switch to PRACTICE: no chips, you speak or type every call from memory, and you work the radio yourself.

2 · Read the briefing like a preflight

Every flight rolls fresh: your callsign, the airport, the runway, the ATIS letter, the QNH, the wind. The briefing card holds all of it — the examiner expects you to arrive knowing your own details, and so does the simulator.

3 · Transmit

When it's your turn, the cue line (✦) tells you what the situation demands. TAP the round mic button, speak your call, then TAP IT AGAIN to send — the button glows red while it's listening. Prefer not to speak? Tap the chips in order (Learn) or type your call (Practice) and press TRANSMIT — typing scores exactly the same. On a phone, tapping is far more reliable than holding.

4 · Missed a call? SAY AGAIN

The amber SAY AGAIN button replays the last ATC transmission — exactly the phrase a real pilot uses. Use it freely; listening is half of radiotelephony.

5 · Work the radio head and transponder

On a handoff (“contact Tower one one eight decimal one”), dial the STANDBY frequency with the M−/M+/k−/k+ knobs and press ⇄ to make it active — in Practice mode, calling on the wrong frequency gets you nothing but static. When ATC assigns a squawk, tap the SQK digits to set it; IDENT flashes your radar return when a controller asks for it.

6 · The examiner probes — answer

Miss a mandatory item and ATC probes you, exactly like the real practical: “confirm QNH?”. Get it wrong and you're corrected and asked to read back again. Each probe costs one point — the flight continues either way.

7 · Debrief on the gradesheet

Every transmission is graded item by item — read-backs, callsign discipline, non-standard words, even your speech rate and filler words on voice calls. 50% is the pass mark, the same as RTR(A) Part 2. Fly the SAME flight again to beat your score, or roll a NEW one — no two are alike.

The theory behind every call — read it in the book

Every phrase this simulator grades is taught in the complete RTR(A) book, free on this site — written for the DGCA RTR(A) syllabus and aligned with the ICAO Manual of Radiotelephony. Fly a scenario, then read the chapter it drilled — that loop is how the phraseology becomes yours.

Ch 13 · Phonetics, numbers & standard wordsCh 14 · Call signs & read-back rulesCh 15 · Aerodrome control — taxi to take-offCh 17 · Approach control & radarCh 18 · Area control & position reportsCh 20 · Distress, urgency & radio failure

Or start at the beginning: the complete RTR(A) book — all 24 chapters covers regulations, radio theory and the full exam arsenal behind this simulator.

How to prepare for the DGCA RTR(A) exam with a radio simulator

RTR(A) is the aeronautical radiotelephony qualification Indian pilots prepare for before they use an aircraft radio. This guide explains what the simulator on this page trains, how to use it alongside the RTR(A) book on this site, and how to turn practice flights into a better result on exam day.

What the RTR(A) assessment tests

As described on this site, RTR(A) has a written paper, which tests what you know about regulations, radio theory and procedures, and a Part 2, in which you speak on frequency while an examiner plays air traffic control. The two reward different skills. The written paper rewards recall. Part 2 rewards how clearly, briefly and correctly you transmit under a little pressure.

Formats, marks and timings are set by the issuing authority and can change, so always read the current exam notice before you book. The practice on this page is built around the Part 2 style of assessment, and the free RTR(A) book on this site covers the written syllabus.

Why a simulator helps

Most students read phraseology many times and still freeze the first time they have to say it aloud. Speaking is a motor skill. You get better by doing it, hearing yourself, and being corrected on the specific item you missed.

The simulator gives you an ATC voice, a briefing, a flight with a different airport, runway, weather and callsign every time, and a gradesheet at the end. Because nothing is repeated, you practise the procedure rather than memorising a script.

Phraseology habits the simulator rewards

The standard is ICAO phraseology, as set out in Annex 10 Volume II and the ICAO Manual of Radiotelephony (Doc 9432). A few habits matter on every flight:

  • Say your full callsign on first contact, then use the abbreviated form only after ATC does.
  • Read back the items that must be read back: clearances, runway in use, altimeter settings, transponder codes, levels, headings and speeds.
  • Use standard words precisely. Say again, standby, wilco and roger each have one meaning.
  • Speak numbers digit by digit and use the phonetic alphabet for letters.
  • Think before you key the microphone, then keep the transmission short. Rambling is marked down as surely as a wrong word.

A simple weekly plan

Start with Learn mode, where you can tap phrase chips, until the structure of a call feels natural. Move to typing your transmissions, then to speaking them. Typed and spoken calls are scored the same way on this simulator, so use whichever helps you improve.

After every flight, open the gradesheet, find the two items you lost the most on, and read the matching chapter of the RTR(A) book before flying again. Re-fly the same flight to beat your own score, then roll a new one to prove it was not luck.

Emergencies and unusual calls

Distress (Mayday), urgency (Pan-Pan) and radio-failure procedures are where students lose the most marks, because they are rare in daily flying. Practise them deliberately. Learn the order of the call, what to say, and what you must not forget, then fly the emergency scenarios until you can do them without notes.

Using this page well

Scenario 1 works without an account, and the rest unlock with a free sign-in. Use headphones in a quiet room if you can, because a real examiner will not repeat himself as often as you would like.

The simulator is practice, not the official exam. It cannot predict your result, but it is a good way to find out which parts of a call you are weak at before an examiner does.
