Aircraft colours

The aircraft icon changes colour depending on the state of the GPS signal;

  • Black when location information is unavailable, or accuracy is > 100 metres
  • Red when location information is available and accuracy is < 100 metres
  • Blue when location information is available, accuracy is < 100 metres and heading information is valid
The blue state indicates the best accuracy level. If the GPS signal degrades or becomes unavailable, the aircraft icon will turn black. In addition all data fields in the flight plan will flag as unavailable (‘–‘).
