Freqwise

Say it right before you say it for real.

Realistic ATC radio practice through your own headset. Automated speech recognition hears your call, a simulated controller answers in a synthetic voice, and fixed rules, not an AI model, check every element of your readback.

One loop, every call.

The same loop as the aircraft, with a controller who waits for you and a check that never gets tired.

  1. Speak

    Hold the transmit key and say your call through your headset, the way you would in the aircraft.

  2. Understand

    Automated speech recognition turns your audio into text, and the engine reads the elements of your call from it.

  3. Operate

    Tune COM 1, read back, hold short, cross, change frequency. The controller and the airfield answer what you actually did.

  4. Improve

    Fixed rules mark every required element. The debrief shows what was missed and names what to practise next.

The radio works like the radio.

The instrument you tune and the check you get are the product itself, not pictures of it. Try the radio.

Tune it yourself

The flight deck's COM 1. Turn the knob to set STANDBY, then swap.

Ground

YR-DMK, contact Tower 118.205.

COM 1
ActiveGND121.905
Standby
Turn to set the standby frequency. Arrow keys step the channel, Page Up and Page Down step the megahertz. Escape returns to the transmit key.
  1. Turn the inner knob (drag, scroll or arrow keys) until STANDBY reads 118.205.
  2. Press the swap key to make it ACTIVE.

Notice the knob skips 118.195: in 8.33 kHz spacing that is not a channel.

Every element, checked

Miss the hold short and it is marked not said, and the controller says it again.

Ground

Yankee romeo delta mike kilo, taxi via charlie, hold short of runway zero nine.

You

Taxi via charlie, Yankee Romeo Delta Mike Kilo.

Ground

Yankee romeo delta mike kilo, negative, i say again, taxi via charlie, hold short of runway zero nine.

You

Taxi via charlie, hold short of runway zero nine, Yankee Romeo Delta Mike Kilo.

Example on a fictional field. These are the marks the real checker gives for these exact words.

A flight plan, lesson by lesson.

From the spelling alphabet to a cross-country: short drills, full phases of flight and Exam checkrides, in the order a pilot meets them. Each lesson says which readback elements it checks.

46 of 46 lessons live today. The rest are on the route, marked, and open the day the engine can check every readback in them.

  1. Foundations

    Callsigns, the spelling alphabet, numbers, key words and what you must always read back.

  2. Controlled aerodrome

    Ground and Tower at a controlled field: from the ATIS to vacating the runway.

  3. AFIS and radio aerodromes

    Strejnic- and Ilfoveni-type fields: information, not clearances. You decide and announce.

  4. Uncontrolled aerodromes

    No one on the ground: announce your position and intentions, and talk directly to other pilots.

  5. CTR and TMA

    Controlled airspace: the PPPIIR first call, entry, transit, restrictions and Special VFR.

    An information service: first contact, flight plans, position reports, requests and transfers.

  8. Transponder, traffic and weather

    Squawk instructions, traffic information, and keeping VMC.

  9. Abnormal and emergency

    Lost, MAYDAY, PAN PAN, lost communications and interception.

    5 of 5 live
  10. Capstone

    The whole flight on the corpus's Strejnic-to-Cluj pattern: an AFIS departure, flight information en route, the arrival to a controlled field, landing and taxi in.

Frequencies, points and altitudes in lessons are training data, not for real-world navigation. Training only; not approved flight training.

Every unit and lesson

Realistic where it counts.

Realism here means the parts of the radio a pilot actually gets wrong, rebuilt faithfully, and nothing pretending to be more than it is.

Real radio operationLive
COM 1 with ACTIVE and STANDBY, a concentric knob and the 8.33 kHz channel plan. You are on the frequency you set, not the one you meant.
Aviation notationLive
Frequencies, runways, routes and codes are shown the way they are written in aviation, in an instrument face: RWY 09, 121.905, F D A.
A different exercise every timeLive
Each lesson generates its exercise from a seed: another stand, another route, another runway in use. You practise the skill, not the answers.
Rules you can inspectLive
The checks are fixed rules traced to published EU rules of the air, and where an exercise is stricter than the rule it says so. That tracing is not yet independently reviewed.
Multiple controller voicesIn development
Today one qualified synthetic controller voice speaks every station. A roster of different synthetic controller voices is in development.

Your progress, drawn across the airfield.

Every check is kept as evidence. The debrief shows each element you got right or missed; your route, rank, weekly goal and skills are worked out from those records by fixed rules. Accuracy earns the XP, not speed.

Below is an example learner three weeks in: invented drills and sessions, drawn by the same components and rules the app uses on your own records.

For flight schools and ATOs.

Consistent, repeatable radio practice between lessons, with your own fleet as the callsigns and assessment an instructor can read. We are looking for a small number of schools to pilot it with.

Start free. Pay for the whole course.

Foundations and your first controlled-aerodrome unit are free, with no card. Pro opens every lesson; its price is still under test and always shown before you pay.

Plans and what they include

Questions pilots ask first.

Is this approved flight training?

No. It is a practice tool for radio communication. It is not approved or certified by any aviation authority, it does not count towards a licence or rating, and it does not replace an instructor, an examiner or an approved training device.

Is an AI deciding whether I was right?

No. AI is used to recognise your speech and to voice the controller. Whether your readback is right is decided by fixed rules in the training engine, one required element at a time, the same way every time. You can see which element was checked and how.

What do I need?

A laptop or desktop with a recent browser, and a headset with a microphone. Voice training does not run on phones yet. A one-minute headset check runs before your first call.

Do you record my voice?

Your audio is streamed to a speech recognition service while you hold the key, so it can be turned into text. We do not keep a recording of your voice or the text of your calls. We keep the result of each check, so your debrief and progress work. The details are in AI and data processing.

What if it mishears me?

If the audio is unclear, nothing is counted against you and you are asked to say it again, as a controller would. Speech recognition can still mishear clear speech; when it does, the check is made on what it heard, and the radio log shows you that text.

Which phraseology does it use?

An ICAO-based European training convention, on a fictional practice airfield. The content has not yet been independently reviewed, and the exercises say so.

What does it cost?

Foundations and your first controlled-aerodrome unit are free, with no card. Pro opens the whole course for a monthly price that is still under test, shown before you pay; cancel any time. See pricing.

What flight schools say

Placeholder. This space holds quotes from instructors and students once flight schools have used the beta. There are none yet, so nothing here is a real quote.

Your first call is a headset away.
