AUTOPILOT

The aircraft has my most advanced (complicated) autopilot yet, IF YOU WANT ALL FEATURES TO WORK PROPERLY YOU NEED THIS ADDON! Altitude modes

  • Altitude hold
  • Vertical speed hold

Heading modes

  • Heading hold
  • VOR heading hold
  • Waypoint heading hold

ILS autoland Roll stabiliser To change modes simply press change altitude/heading mode and then confirm your changes. The autopilot will work once a mode is selected and the autopilot master is ON. You can set the target altitude/heading and change the vertical speed limit.


VOR & ILS TO USE THESE FEATURES YOU ARE REQUIRED TO HAVE THE NAVIGATION PACK ENABLED To select VOR waypoints choose the HSI screen (1st screen on the MFD), press "T" in the upper left corner and select a waypoint from the list, if you now return to the HSI by pressing "T" in the left upper corner you will see the target heading to your selected waypoint. To use the ILS autoland feature, follow the same steps as for the VOR heading selection and select any waypoint that has "base" for example RWY 32 BASE.. then you can enable the ILS overlay on the PFD and see the glideslope there. When landing with the ILS extend your approach to at least 15km from the airfield in and enable the ILS autoland feature and the autopilot when you’re further then 15km and aiming roughly towards the airfield. When is it enabled, it will automatically create and follow the approach and control everything needed for the landing. After landing turn off the ILS autoland and press reset ILS.
