Description
A dual flight management system (FMS) provides integrated cockpit and flight management functions. Each flight management system (FMS 1 and FMS 2) is composed of a control display unit (CDU) in the cockpit, and a flight management computer (FMC) in the underfloor avionics equipment bay. A single data base unit (DBU) allows data to be uploaded or downloaded to all of the FMCs. A third flight management system (FMS 3) may be installed as a customer option.
The FMS cockpit management functions include:
.
Navigation sensor control;

.
Radio tuning;

.
Multifunction display (MFD) control menus;

.
Navigation database management;

.
Control and management of the data loader; and

.
Management of the data interface with external systems (AFIS).

Flight management functions include:
.
Continuous calculation of the integrated navigation solution;

.
Flight plan inputs by the crew;

.
Lateral flight plan point-to-point navigation;

.
Vertical navigation;

.
Performance calculation; and

.
Lateral/vertical steering commands to the flight control system.

The third FMS, if installed, is defined as a “hot spare”, and is fully functional when selected.

Components and Operation
FMS Control Display Units (CDUs)
The FMS CDU is the cockpit interface of the flight management system. It allows the flight crew to input, modify, and execute flight plans, as well as calculate aircraft performance. It also acts as a radio tuning interface through a dedicated TUNE page, and is the primary means of control for most navigation sensors. The CDU controls certain information displays on the MFDs, and advises the flight crew of FMS system status through a variety of message formats.
Power Supplies
.
The No. 1 (left) CDU is powered by BATT bus.

.
The No. 2 (right) CDU is powered by DC bus 2.

.
The No. 3 CDU is powered by the DC essential bus.

Scratchpad and Line-Select Keys
The FMS CDU is arranged so that all flight crew inputs are conducted through a “scratchpad”, which allows easy data input and retrieval. An alphanumeric keypad permits entry of all relevant data to the scratchpad, and line-select keys are used to insert the data in the appropriate area of the display page. Most information contained on the display page can similarly be “line-selected”, and is then transferred to the scratchpad for reference or modification.
Execute Key
Most entries made into the flight plan or performance calculations are considered modifications to the active flight plan, and must be executed using the EXEC function key before they become active components of the flight plan. This permits the flight crew to cross-check any modifications prior to committing them to the active flight plan.
