When any storage capacity is full, entries which are no longer required should be
deleted by the crew to make space for additional new entries. Created waypoints
cannot be stored in the database runway category.
The FMC contains two sets of navigation data, each valid for 28 days. Each set
corresponds to the normal navigation chart revision cycle. The FMC uses the
active set for navigation calculations. The contents of the navigation database are
periodically updated and are transferred to the FMC before the expiration date of
the current data.
Thrust Management
The autothrottle operates in response to flight crew mode control panel inputs or
to automatic FMC commands. Reference thrust can be selected on the N1 LIMIT
page. Automatic FMC autothrottle commands are made while VNAV is engaged.
The autothrottle system:
• uses reference thrust limits calculated by the FMC
• commands the thrust levers
• commands thrust equalization through the electronic engine controls.
Thrust limits are expressed as N1 limits. Thrust equalization references N1.
1B801 - 1B806
The FMC calculates a reference thrust for the following modes:
The thrust reference mode automatically transitions for the respective phase of
flight. These modes can be selected on the N1 LIMIT page. The selected thrust
reference mode is displayed on the thrust mode display.
The flight crew can specify the thrust reduction height where the transition from
takeoff to climb thrust takes place by making an entry on TAKEOFF REF page 2.
Allowable entries are 800 feet to 9,999 feet.
The default value is determined by the airline and is stored in the model/engine
database.
Reduced Thrust Takeoff
Reduced thrust takeoffs lower EGT and extend engine life. They are used
whenever performance limits and noise abatement procedures permit.
• takeoff
• derated takeoff
• assumed temperature takeoff
• takeoff bump (as installed)
• climb
• reduced climb
• cruise
• continuous
• go–around.
