Copyright © The Boeing Company. See title page for details.
L.10.6 D615Z003-TBC
# The use of VNAV and/or LNAV is prohibited with QFE selected.
Non-AFM Operational Information
The use of Integrated Approach Navigation (IAN) procedures is prohibited with
QFE selected.
Fuel
Fuel Temperature
# The maximum tank fuel temperature is 49° C (120° F) for Jet A, Jet A-1, JP-5
or JP-8.
[Option - English / Metric units]
# Thermal buffer fuel is required if the ground ambient air temperature at the
airport of departure exceeds 110° F / 43° C on flights requiring less than 53500
pounds / 24267 kilograms of fuel. Add thermal buffer fuel to the planned fuel load
to keep main tank fuel temperature within limits. (Refer to Operations Requiring
Thermal Buffer Fuel in Chapter SP, Section 16, for additional information.)
# Tank fuel temperature prior to takeoff must not be less than -42° C or 3° C above
the fuel freezing point, whichever is higher. In-flight tank fuel temperature must
be maintained at least 3° C above the freezing point of the fuel being used. The
use of Fuel System Icing Inhibitor additives does not change the minimum fuel
tank temperature limit. (Refer to Performance Initialization Page
in Chapter 11,
Section 40, for additional information.)
Fuel Loading
# Main tanks must be scheduled to be full if center tank fuel is loaded.
[Option – English / Metric units]
Note: The center tank may contain up to 3000 pounds / 1360 kilograms of fuel
with less than full main tanks provided center tank fuel weight plus actual
zero fuel weight does not exceed the maximum zero fuel weight, and
center of gravity limits are observed.
Warning Systems
GPWS - Look-Ahead Terrain Alerting
# Do not use the terrain display for navigation. (Refer to GPWS Look-Ahead
Terrain Alerting Display and Annunciations in Chapter 15, Section 10, for
additional information.)
