IHADSS EXAM QUESTIONS WITH COMPLETE
SOLUTIONS
Command Heading
This symbology indicates heading to next navigation waypoint
as selected from the TSD.
Yes
Is the command heading edge limited?
Heading miscompute cue
This symbology is displayed if heading differs by more than 4
degrees as detected by EGI cross monitoring.
Atitude miscompare cue
This symbology is displayed when roll or pitch differs by more
than 3 degrees as detected by EGI cross monitoring.
Attitude miscompare cue
This miscompute cue is of higher priority than VEL cue.
VEL miscompare cue
This symbology is displayed if velocity difference exceeds 10
knots in any axis.
Alternate Sensor Bearing
This symbology indicates the opposite crew members selected
LOS with respect to the heading of the aircraft
When the other crew members selected sight is FCR.
,When is the alternate sensor bearing not presented?
Automatic Direction Finder
This symbol is an inverted lollipop representing the current
bearing to the tuned NDB
1. Altitude is 10% below the LO set altitude and between 11 and
999 ft AGL
