• Altimeter and terrain awareness: the altimeter tape includes a TAWS (Terrain Awareness
Warning System) bar and terrain depiction (In red).
Note: See AvMap EKP V User manual for more details on the TAWS feature.
• HSI Source: if no valid magnetic compass data is available (i.e. compass not yet calibrated),
the HSI display is based on GPS “Course over Ground” and the HSI source flag shows “GPS”.
When correct compass data is available the source indicator changes to “AHRS” and proper
magnetic heading is used to drive the instrument.
