Go-around %N1
To find Max Go-around %N1 based on normal engine bleed for packs on
(Auto) and anti-ice off, enter the Go-around %N1 table with airport
pressure altitude and reported OAT or TAT and read %N1. Apply the
appropriate bleed setting %N1 adjustment shown below the table. %N1
adjustments are shown for engine bleed to packs off operation, packs high
operation, and wing anti-ice on.
VREF
The Reference Speed table contains flaps 40, 30, and 15 landing speeds for
a given weight. Apply wind correction shown as required.
Advisory Information
Normal Configuration Landing Distance
The normal configuration distance tables are provided as advisory
information to help determine the actual landing distance performance of
the airplane for different runway surface conditions and brake
configurations.
If the surface is affected by water, snow or ice, and the braking action is
reported as "good", conditions should not be expected to be as good as on
clean, dry runways. The value "good" is comparative and is intended to
mean that airplanes should not experience braking or directional control
difficulties when landing. The performance level used to calculate the
"good" data is consistent with wet runway testing done on early Boeing
jets. The performance level used to calculate "poor" data reflects runways
covered with wet ice.
Dry runway landing performance is shown for max manual braking
configuration and autobrake settings max, 3, 2, and 1. The autobrake
performance may be used to assist in the selection of the most desirable
autobrake setting for a given field length. Selection of an autobrake setting
results in a constant rate of deceleration. Maximum effort manual braking
should achieve shorter landing distance than the max autobrake setting.
The reference landing distance is a reference distance from 50 ft above the
threshold to stop based on a reference landing weight and normal approach
speed for the selected landing flap at sea level, zero wind, zero slope, and
two engine detent reverse thrust. Subsequent columns provide adjustments
for off-reference landing weight, altitude, wind, slope, temperature, speed,
and reverse thrust. Each adjustment is independently added to the
reference landing distance.
