Introduction

Although in everyday life people prefer texting over calling, it is the opposite in aviation. Tactical information exchange between air traffic controllers (ATCOs) and pilots is still done over analog radio voice channels. For this purpose the VHF (Very High Frequency) band between 118MHz and 136MHz is used. The band is divided into 8.33kHz channels.

This site is interfacing Opensky Network's Air Traffic Communication (ATC Platform), which has been set up to collect voice recordings through a network of volunteers. The recordings are automatically transcribed and stored on our infrastructure.

Our mission has remained the same over the years - that is, to improve security, reliability, efficiency and sustainability of the air space usage by providing open access of real-world air traffic control data to the public and are available for use for our users. So if you have a specific use case where either recordings or their transcripts are useful, do send us an email contact@opensky-network.org and tell us about it.
