Downwind f1 ight within 60 sec of IAS, GS, elapsed t ime To detect early downwind tum
take-off after tak.e-off.
Downwind f1 ight within 60 sec of IAS, GS, elapsed time To detect late turn to final shortly

Minimum altitude in auto rotat ion NR, total Tq, Rad Alt To detect late recovery from
a utorotat ion.
Low cruising (inenial systems) GS, V /S, elevation, Lat & Long To detect an extended low-level
flight. Ground speed is less
accurate with more false alarms.
Lat & Long used for geographical
boundaries.
Low cruising (integrated systems) Rad Alt, elapsed time, Lat & Long, To detect an extended low-level
ground switch (similar) flight.
Flight - Attitude and controls
Excessive pitch (height related - Pitch attitude, Rad Alt elevation, To identify iM ppropriate use of
turnover (T/O), cru ising or landing) Lat & Long excessive pitch attitude during
flight. Height limits may be used
(i.e. on take-off and landing or
< 500 ft) - Lat & Long required for
specific-location-related limits.
Elevation less accurate tllan

identify the landing phase in a
specific locat ion.
Excessive pitch (speed related - Pitch attitude, IAS, GS, Lat & Long To identify inappropriate use of
T /0, cruising or landing) excessive pitch attitude during
flight. Speed limits may be used
(i.e. on take-off and landing or in
cru ising) - Lat & l ong required for
