SYSTEM ALERT
MESSAGE
DESCRIPTION
ACTION
CHECK SELECTED ALT
(continued)
Message clears in Climb: If the selected
altitude is lowered to the climb waypoint
altitude constraint, or the pilot allows the
aircraft to climb above the climb waypoint
altitude, the message will be cleared.
Message clears in Cruise: If the crew has
lowered the selected altitude than 150 feet
below the cruise altitude when approaching
the top-of-descent anticipation point, or if the
selected altitude is not changed by the pilot,
the message will be cleared when the along
track distance past the top-of-descent
anticipation point is greater than 15 nautical
miles, or when the planned step point has
been sequenced.
Message clears in Descent: If the stabilized
selected altitude is lowered at least 150 feet
below the descent waypoint altitude constraint,
the message will be cleared.
CHECK TAKEOFF
SPEEDS
1.When:
• the actual aircraft gross weight
(ZFW + Fuel weight decoded
from the fuel computer) plus 10%
of the TAXI fuel weight (to prevent
spurious alerts) is less than the
predicted takeoff gross weight
(ZFW + BLOCK fuel weight -
TAXI fuel weight),
• the aircraft is on-ground,
• at least one takeoff speed has
been entered on the TAKEOFF
REF page and
• the T/O DATA DELETED
message is NOT currently raised.
2. If the FMS is in synchronized mode,
and at least one on-side and one off-
side takeoff speed differs by more than
1 knot for at least 5 seconds.
Ensure that the entered BLOCK fuel weight is
consistent with the actual fuel on board weight.
Verify that the entered TAXI fuel weight is
correct.
If required, re-enter the takeoff speeds to
account for the new aircraft actual or predicted
takeoff gross weight.
If required, re-enter the takeoff speeds and
confirm on-side and off-side takeoff speeds
match.
CHECK TRUE/MAG REF
Phase of flight is Approach or Terminal
and the angle reference is TRUE.
If required, change Angle reference to MAG via
FMS SETUP page (or alternatively via external
switch).
CLB IN DES NOT
ALLOWED
The FMS detects a climb segment in
the descent profile during the vertical
profile generation.
NOTE: The only possible way for
having a climb segment in the descent
profile is to manually enter an altitude
constraint at a down-path waypoint that
is higher than the altitude constraint of
a waypoint before.
Review the flight plan and remove any climb
segment falling into the descent profile.
