FLIGHT MANGAGEMENT
SYSTEM(FMS)
Modern aircraft uses large number of sensorsand technology .
The information is managed by FMS
The FMS integrates information from :navigation, performance, and flight parameters.
Provides consolidated navigation and flight
control for efficient management of aircraftresources

COMPONENTS
A typical FMS consists of:
Flight Management Computer
Flight Control SoftwareVisual Display Unit

HOW IT WORKS
The Flight Management Computer is supplied with information from: Navigation systems
Inertial reference system
Air data computer
Engine and system status
Aircraft specific performance database Route, procedure and terrain database
TCAS
Pilot inputs
It analyzes these inputs and continually reevaluates changingparameters to provide the autopilot, flight director, and auto-throttles
with commands which optimize all aspects of a flight.

OPERATION
Initialization with Route parameters.( That is flight Path)
Navigation and aircraft performance database updated as perspecific aircraft)
initial position to be defined usually the start place.
The pilot becomes a manager of this sophisticated system,
monitoring progress and updating or changing parameters asnecessary.

WHAT IT DOES
The FMS is capable of : Calculating optimum rate of climb/descent, altitude,
power setting.
Controlling the aircraft to meet these optimumparameters through autopilot and auto-throttle.
Guiding pilot controlled flight path through a flightdirector, and target speed and engine setting bugs.
Cross referencing multiple navigation sources to
continually update position. Automatically tuning en-route navaids.
Alerting pilots of systems status and malfunctions.

ADVANTAGES
The workload reduction associated allowspilots more time to analyze and makedecisions. (drink coffee too)
Computer generated efficiency profiles aremore accurate.
Navigation accuracy is improved through
integration and cross referencing ofmultiple sources.
Improves situational awareness.

DISADVANTAGES
Heavily dependent on Pilot input.
Possibility too much Human interventions
leading to error
Expensive.
