The FSi Radio is an universal all in one aviation radio addon for your favorite flight simulator. It allows you to control the frequencies for the whole radio stack and it also includes DME for the IFR enthusiasts.

IMPORTANT - this app is intended for Microsoft Flight Simulator X or X-Plane users and is not usable on its own. You will need the iPad and the computer running the simulator to be on the same network.

COM1 and COM2 VHF voice radio mode
NAV1 and NAV2 VHF navigation radio mode
ADF1 and ADF2 navigation radio mode
DME1 and DME2, linked to NAV1 and NAV2 receivers
Active and Standby frequency displays, allowing easy frequency adjustment with an instant swap function

Remembers the last mode used. You can have up to 8 iOS devices in your setup, each controlling separate instrument, or used as a backup for the primary one.

Beautiful day and night display schemes.

FSi Server is required to establish the connection between Flight Simulator and your device. It can be downloaded free at http://avioware.com/download.

Not compatible with X-Plane 10

This app works fine with X-Plane 9 and does everything it's supposed to do. However, while it will show the frequencies your radios are tuned to in X-Plane 10, it will not actually tune them or swap to the stand-by frequency.

As an aside, it would be nice if it worked with the transponder, too. Currently, it only controls com, nav, and ADF.
