The document discusses a flight management system (FMS), which is a computer system that automates many in-flight tasks. An FMS has several key components, including a control display unit in the cockpit and navigation displays. It contains navigation and performance databases. The FMS allows pilots to enter flight plans, monitors the aircraft's position, calculates efficient routes, and can guide the autopilot. FMS provides advantages like improved navigation, fuel efficiency, reduced workload, and accuracy, but also has disadvantages such as potential for data entry errors, loss of situational awareness, and high cost.

3. Introduction

Modern aircraft are filled with the latest technolgy.

Technology which greatly reduces workload if the
systems are understood and used properly.

The heart of all these systems is the FMS.

4. What is FMS?

FMS is stand for Flight Management System(FMS) is a
specialized computer system that automates a wide
variety of in-flight tasks.

FMS acts as the 'brain' of the aircraft navigation
system.

5. FMS Components

From the cockpit,the FMS is normally controlled through a
Control Display Unit(CDU) which incorporates
a small screen and keyboard.

The FMS sends the flight plan for display
on the EFIS,Navigation Display(ND).

6. FMS Database
FMS Contains two types database which are:

NAVIGATION DATABASE

PERFORMANCE DATABASE

7. FMS Navigation Database
All FMS contain a navigation database.

The navigation database contains the elements from which
the flight plan is constructed.

Navigation Database include
-Waypoints, -Airways(highways in the sky)
-Radio navigation aids(DME,VOR,ILS)
-Airports(Runways),Holding patterns
-And a variety of other related information

8. FMS Performance Database

During preflight,other information relevant to managing
the flight plan is entered.

This can include performance information such as
-Maximum take-off weight,
-Fuel weight
-Center of gravity.
-It will include altitudes including the initial cruise altitude.

9. FMS Operation

Pilot key in input route information to CDU of FMS.

The navigation and aircraft performance database must be
verified.

Routing must be confirmed accurate and correct and any
ATC changes to expected routing must be entered
manually.

The pilot becomes a manager of this sophisticated system,
monitoring progress and updating or changing parameters
as necessary.

10. FMS Advantages

FMS are designed to:
-Improve Navigation
-Aid Fuel Efficiency
-Reduce Crew Workload
-More Accurate

11. FMS Advantages

FMS are designed to:
-Navigation

A principal task of the FMS is to determine the aircraft's
position

Given the flight plan and the aircraft's position,the FMS
calculates the course to follow.

Autopilot can be set to follow the course.

12. FMS Advantages
-Aid Fuel Efficiency

It calculates performance data and the most fuel-efficient
route to be flown based on typical aircraft parameters such
as weight,cruise altitude and actual aircraft
position,regardless of weather conditions.
-Reduce Crew Workload

Allows pilots more time to analyze and make decisions.

13. FMS Advantages
-More Accurate.

Computer generated efficiency profiles are more accurate.

Navigation accuracy is improved through integration and
cross referencing of multiple sources.

14. FMS Disadvantages
Error Data Entry.
-Reliant on pilot input.
-There is potential of misinterpretation or erroneous data
entry.

Loss of situational awareness
-Loss of situational awareness.Pilots may becomes so
involved in operating and monitoring the system that they
forget to look outside.

Expensive
