NORMAL HANDLING
Stall Characteristics
(continued)
It is acceptable for stick pusher operation to be coincident with the natural stall, provided that any rolling
tendency can be restrained to within 20° of bank angle by normal use of ailerons. Some aerodynamic
buffet may occur briefly at the point of stall.
Power-off stalling speeds in terms of Indicated Air Speed (IAS) are given for various configurations in
the Airplane Flight Manual Figure 5.05.6. These airspeeds apply to an altitude of 15,000 feet and are
the stall identification speeds at forward CG and therefore differ from the values shown in the AFM
Figure 5.10.4 which are based on the minimum airspeed obtained during the stall.
AVIONICS AND NAVIGATION
Flight Management System (FMS)
NOTE:
The Flight Management System present position co-ordinates are to be checked for
acceptable accuracy before the airplane flies beyond the range of reliable ground navaids.
All data insertions, including ramp co-ordinates, previously inserted into the Flight Management System
should be recalled and verified, preferably by another member of the aircrew.
The verification should include a comparison of the displayed distances between waypoints and the
distances shown on the flight path.
The installed Long Range navaids should be checked against the FMS position while still in DME
coverage before any oceanic crossing. Any FMS messages concerning navigation aid accuracy should
be investigated. Refer to the relevant Flight Management System manual.
NOTE:
If there is any doubt as to the correct position, the controlling authority should be informed
particularly on an oceanic flight.
The Flight Management System should be carefully monitored throughout the flight to make certain that
present position and planned forward flight path satisfies the clearance which is currently effective.
On oceanic flights, and other remote areas, the monitoring procedures should include a routine check
of indicated position about 10 minutes after passing each waypoint.
In the vicinity of the equator or prime meridian, care must be taken to make sure that the co-ordinates
of data inserts are correctly designated (N/S, E/W).
