NOTES:
1. Once in flight, when the actual cruise altitude is
lower than the entered or calculated initial
cruise altitude, the initial cruise altitude entry
must be adjusted to the lower value. Entering
the actual cruise altitude places the FMS in the
cruise mode and adjusts the performance
predictions to account for the lower cruise
altitude.
2. The speed command for a level--off below the
entered or calculated initial cruise altitude is the
climb speed target.
— 5L
-- Cruise winds at the anticipated cruise altitude are entered
at 5L. Data entry formatting and syntax is consistent with entry
of wind magnitude and direction on other FMS pages. The
default CRUISE WINDS value is zero.
In addition, the altitude is entered before the cruise wind is
accepted. Entering *DELETE* returns the default value of zero.
— 5R
-- 5R is associated with 5L and gives the pilot the ability to
specify the cruise wind altitude. Data entry is consistent with
entry of cruise altitude on other FMS pages. The default value
is set to zero. In addition, the FMS gives the pilot the ability to
enter winds from altitudes of --1300 to 60,000 feet.
— 6L
-- Selection of this line gives access to the APPROACH
(APP), and GO--AROUND speed pages.
D
Current Ground Speed/Fuel Flow Method
-- The CURRENT
GS/FF method of performance initialization is similar to the PILOT
SPD/FF initialization with the exception that no cruise fuel flow entry
is permitted on the PERFORMANCE 2/3 page. The default fuel flow
value at 2R is 450 kg/hour.
D
APPROACH SPEEDS
-- The APPROACH SPEED 1/2 page,
shown in Figure 5--7, is used to enter approach speed and restriction
limits. Approach speed and restriction limits are used to compute
FMS speed targets during approach.
