HSI PAGE
Pressing the ENTER key while being in Map mode
will bring up the HSI page.
The HSI page shows:
 Compass rose, showing ground track,
which is the true track over ground,
taking crosswinds and sideslip into
account. It does NOT show magnetic nor
true heading, like a normal gyro based
HSI.
 Course Needle, showing the active flight
plan leg bearing.
 Course deviation indicator bar (middle
part of the Course needle), showing the cross track error. Each dot represents 1 nautical mile.
 TO/FROM flag showing the position relative from the active flight plan leg.
 Right part of the screen shows Ground speed, Distance to next waypoint, Ground track (same as
Compass rose) and next waypoint bearing.
If the Ground track value and the Bearing value are equal, this indicates that the aircraft is heading straight
towards the next waypoint, but not necessarily following the flight plan leg.
HSI SAMPLES

Still 3 miles left of the flight plan leg, but on an intercept heading of 40°
