SkyYoke lets you talk to Infinite Flight's air traffic control from the phone, so you do not need to reach for the simulator's screen [Infinite Flight]. ![The ATC panel with option keys and messages](https://ifkits.com/wiki/img/atc-panel.png) ## Opening the panel The **ATC** button sits at the bottom-left of the cockpit screen. A badge shows how many messages you have not read. Tap it to open the **Air Traffic Control** panel. ## Sending a message Infinite Flight's ATC window lists what you can say, each with a number in its top-left corner. SkyYoke cannot see the wording of those options, only their numbers, so: 1. Look at Infinite Flight's ATC window and find the option you want. 2. Press the key with the same number in SkyYoke's **Option keys**. **Show IF ATC window** opens the ATC window in Infinite Flight if it is closed. ## Reading messages Messages appear on the right of the panel automatically once you are tuned to an ATC frequency and the controller transmits. ## Quick reply When ATC is waiting for your reply, the ATC button turns green and reads **Hold to reply**. Hold it for about a second to send the standard reply (option 2, usually the readback); it flashes **Reply sent**. A short tap still opens the full panel. > **On multiplayer servers with live controllers, always follow the controller's instructions first, before any automation in SkyYoke.** ## AI ATC An AI air traffic controller is in development and not yet available in the app. This page will be updated when it is released.
