The Primus APEX system has switched the long term reference source for the HSI
heading from a gyro based magnetically corrected heading output to a magnetically
compensated Track based display.
Note
The main difference is that the drift angle, i.e. difference between aircraft heading
and track is not shown. The card shows actual track (related to Magnetic North)
being made.
