FLIGHT MANAGEMENT SYSTEM - INTRODUCTION

GENERAL DESCRIPTION / INTRODUCTION

The CRJ is powered by two Collins FMS-4200 flight management computers. The control display units (CDU)

are the interface between pilots and the FMS units itself by means of data / information display and data

entry. The FMS provides lateral guidance and vertical advisories based on the entered flight route,

performance data and data collected from several sensors.

The stored performance database is advisory only, as the FMS has no ability to control vertical or speed modes

of the autopilot. Only heading information based on the programmed route are provided to the autopilot in

LNAV mode.

This chapter in the systems manual only provides a very basic introduction to the flight management system.

More details will be introduced in the following chapters.

WHERE TO FIND THE FMS/CDU AND BASIC LAYOUT

The control display units, CDUs sit on the upper part of the pedestal. Both CDUs are identical regarding

functionality and layout.

The following picture shows the basic layout of the control display unit, CDU.

- Title line

The title line shows the page title, or mode as well as the current page number and number of total

pages, of applicable

- Label line

The label lines are aligned with the respective line select keys. They show information related to the

current page. Pressing the line select key adjacent to the label line, allows copying the indicated

information into the scratchpad or vice versa.

- Keypad

Used to enter alpha-numerical data in to the scratchpad.

You may use your mouse to enter data into the FMS and select certain functions, nevertheless you may also

activate a mode to use keyboard commands to directly enter data / select functions from the FMS. Please bear

in mind that as long as the keyboard mode is activated other key assignments in your flightsim won’t work.

Note

In case you are using the keyboard entry mode do not forget to deactivate it when entries are completed to

gain full function of regular flightsim functions.

The table on the following page shows the available key commands.

following information:

- Direction difference displayed as a heading in XXX°

- Distance difference displayed as XX,X nm (values above 99,9 will be displayed as 99,9 as well)

- The position drift rate given in XX,X nm per hour

VOR CTL STATE SUB-PAGE

The VOR control page allows you to configure whether certain VORs are used or not to be used to assist during

initial position initialization. Press line select key 5L to either enable or disable VOR Control.

Enter the VOR’s identifier into the scratchpad and then press the respective line select key to either select or

inhibit certain VORs. Use LSK 1L and 1R to select VORs to be used during position initialization. Use LSKs 2L, 3L,

4L as well as 2R, 3R and 4R to enter VORs to be inhibited during position initialization.

The following picture shows VOR FFM to be used and VOR RID and MTR to be inhibited during position

initialization.

FMS_29.jpg

Entered VORs are used as long as they are stored in the FMS or unless a database update was performed.

FMS CTL STATE SUB-PAGE

The FMS control page allows to toggle between displaying true or magnetic (magnetic north) heading as well

as switching between dependent and independent mode of the two FMS.

Press LSK 1L to toggle between true and magnetic heading.

In case true heading is selected, the heading indications on the CDU and EFIS switch to true heading.

Furthermore heading indications on the FMS are designated by a small “T”. Whereas wind information (PROG

page) and VOR bearing information (VOR/DME STATUS page) is always displayed as magnetic heading.

FMS_31.jpg

Pressing LSK 2L would toggle between dependent and independent mode of the two FMS. Independent mode

is not simulated though – for the sake of clarity the following section briefly describes its function though.

In dependent mode the flightplan information are synchronized between both FMS. When switching to

independent mode both FMS may process different flightplan information. When switching to independent

mode you are required to select one FMS as the master / source of information for the autopilot system.

When switching back from independent mode to sync mode, all information from the selected master FMS are

written over the information of the other FMS. Accordingly you are required to confirm when switching back

to sync mode.

ROUTE MENU SUB-PAGE

The ROUTE MENU page allows to store and load flightplans. When the ROUTE MENU page is opened, the

option PILOT ROUTE LIST is displayed – press LSK 1L to open the PILOT ROUTE LIST.

The options CO ROUTE LIST and DISK ROUTE LIST of the real aircraft are not simulated.

FMS_32.jpg

This opens the list of available flightplans. Press LSK 1L/R, 2L/R, 3L/R, or 4L/R to select and load a flightplan.

To store a flightplan enter a suitable filename into the scratchpad and press LSK 6L to store the active

flightplan or LSK 6R to store the secondary flightplan. ROUTE SAVED is displayed in yellow font when saving the

flightplan was successful.

Press LSK 5L to view the FLTPLN page for the secondary flightplan.

Press LSK 5R to return to the ROUTE MENU page.

The DEFAULTS page allows to enter several default values for the CRJ.

Changing of the default value does not affect active flightplans (there are a few exceptions) but only when a

new flightplan is created. Some of these values may be overwritten by the respective pages of the flighplan.
