TWR 118.30

AVN663, runway 09R cleared to land.

01The job

Every position

Issue clearances at delivery, push and taxi on the ground, run the runways from the tower and sequence arrivals on approach.

Talk to them

Hold your talk key and speak like a controller, or type the same calls. Pilots read back, question and comply.

Radio that sounds real

Neural voices give every crew its own voice on the frequency. They run on your PC, with no account and no internet connection.

Offline speech recognition

Your voice is recognised on your own machine and never leaves it. A microphone is optional: typing does everything.

Three airports

Taxiway webs, parallel runways and busy aprons. Weather, wind and traffic change from shift to shift.

An invented world

Airlines, callsigns and airports are made up, with their own liveries and character.

“Windows protected your PC”? The game isn't code-signed, so SmartScreen reports an unknown publisher. Click More info, then Run anyway.

No voices, or voice control not working? Your antivirus may have quarantined tts\piper\piper.exe or stt\whisper\Release\whisper-server.exe. Restore them and add the game folder as an exception, or unzip the game again.
