Get a PFD and HSI for X-plane. Connects via network (wifi or hardwired). The app also includes an autopilot panel. The instruments are inspired by Garmins G5 type FPD and HSI
This app requires X-plane (v.11) to work. You can get it at https://www.x-plane.com/.
To use all features of the autopilot you must select an airplane in x-plane with G1000
Please note that the app initially runs in trial mode. Trial mode has full features, but will timeout after about 10 minutes. You then have to restart the app or buy access via in-app purchases to continue.
