FMS (Controls and Indicators 7-90.1)

A little general theory: All FMS systems that I have used function or think in a
“Mode” pattern. This is to say that the FMS must always be in a mode or phase
and be aware of what the aircraft is doing to “know” what mode it should be in.
The FMS will have many different ways to identify a mode change but it will need
to change modes during every flight. The pilot should be aware of the modes
and their changes (this is starting to sound like marriage counseling…). The
Airbus is no different. For vertical planning the FMGC has modes called Flight
Phases that are named Preflight, Takeoff, Climb, Cruise, Descent, Approach, Go
Around and Done. In addition the FMS needs to know when the aircraft is in taxi,
engine-out and landing modes. With the pilot entering the proper needed data
during initialization the FMS is able to properly plan and control a flight through
all the necessary phases or modes.

Further, the pilot must enter a route of flight to allow for lateral planning. This will
also involve modes, in this case, takeoff runway, SID (if applicable), enroute,
STAR (if applicable) and approach/go around and landing runway. The pilot will
enter the needed route data before flight and modify it in-flight as necessary.

Some changes the pilot will make are considered Strategic (entire flight) and
some are Tactical (current flight phase or mode). As you learn the different
functions of the FMGC and the Autoflight system be aware of whether a function
is Strategic or Tactical. For example the Cost Index is strategic but the descent
speed is tactical.

If a page is longer than one screen can show you will use the scroll or slew keys

(up/down arrow keys, ) to show additional information. If there is more than
one page to a key you can press the NEXT PAGE key to see the succeeding
pages. Sometimes additional information can be accessed from a page and you
will see an on screen prompt ( <, >, or * ) to present that new page. See PH
17.6.1 for full information.

FMGC Stuff: Now for some general info on the FMGC!

 Airbus Gotcha: US Airways is in the process of merging with America West to
form a combined new US Airways. As both airlines have different versions of the
A320 there will be differences. Additionally, US Airways is also installing new
FMGC‟s in the A320 fleet. These will be referred to as the FMS 2. This has been
an optional FMGC that other airlines have used in the past so is not really new,
just new to US Airways East. The new FMS is the Smiths and the “old” one is the
Honeywell. For our purposes the old Honeywell unit will be the FMS and the new
Smiths unit will be the FMS 2. Differences will be noted later.

DIR key: This key is one of the most used and will allow the pilot to go direct to
any fix that the FMGC will recognize. If the FMGC doesn‟t recognize the fix then

Line Fixes

NOTE: on ground Flight Crew can reset any computer EXCEPT:

 ECU (engine control unit), EIU (engine interface unit) while engine running.
 BSCU (Brake Steering Control Unit) while taxiing, set parking brake first

To reset CB in air check chart listed in QRH, Miscellaneous, Computer

 Airbus Gotcha: Never pull the following CB‟s in air:
 SFCC (Slat/Flap Control Computer)
 ECU and/or EIU

 Captains – on overhead panel – MCDU – CB# B1, FMGC – CB# B2
 F/O‟s – behind F/O – MCDU – CB# N20, FMGC – CB# M17

Reverser unlocked message on engine start
1. Engine Master OFF
2. Reset Engine Mode selector to NORM for 10 secs., then IGN/START

If this doesn‟t work then:
3. Turn on ENG FADEC GRND PWR on overhead maintenance panel, then off

GPS Primary Lost showing on both ND’s after IRU’s align
If the GPS signal is not available after the IRU‟s align a possible fix is:

1. Data Key
2. Position Monitor
4. DESELECT *GPS showing (if SELECT *GPS is showing press LSK to

change it) this line shows what WILL BE selected.

Printer “spewing” maintenance codes after shutdown
 MCDU Menu
 Programming
 Programming Menus
 Report Inhibit
 Print NO (green)

Note: when changing printer paper roll make sure that the printer latch is
completely secured or printer will not function. Press SLEW to check.

Reset CIDS – Reset CB‟s: G1, M5 and Q14 for more than 10 secs. Then wait at
least 3 mins. after reset.
