Study Notes

A330-200/300 Differences from A318/A319/A320/A321 (CFM56/V2500) Training Manual - Autoflight

  • This manual is for training purposes only and should not be used for any other purpose
  • These notes are not updated

Auto Flight Line Maintenance Briefing (2)

  • This module describes the operational use of the Automatic Flight System (AFS) and the Flight Management Guidance and Envelope Computers (FMGECs) in a normal operation with total availability
  • Aircraft control is either automatic (AutoPilot or AutoTHRust) or manual (pilot action on side-sticks or thrust levers)
  • Aircraft guidance is either managed (targets provided by the Flight Management part) or selected (targets selected by the pilots via the FCU)
  • As soon as electrical power is available, the Flight Director (FD) is automatically engaged provided that the power-up test is successful. No FD guidance symbols are displayed on the EFIS PFDs until take-off.

MCDU Initialization

  • The pilots use the MCDU for flight preparation
  • Includes choice of the data base
  • Flight plan initialization, radio navigation entries and checks
  • Performance data entry such as V1 (decision speed), VR (rotation speed), V2 (take-off reference speed) and FLEX TEMP (flexible temperature) and weights
  • Entry of the flight plan (lateral and vertical) and V2 into the MCDU is taken into account by the FM part and confirmed by the lighting of the related lights on the FCU
  • An altitude also has to be selected through the FCU

Autothrust Engagement

  • A/THR engagement depends on the thrust lever position for take-off
  • For take-off, the thrust levers are set to either the Take-Off/Go-Around (TO/GA) gate or the FLEXible-Maximum Continuous Thrust (FLEX-MCT) gate
  • When the pilot moves the thrust levers to the TO/GA gate, the FMGECs automatically engage the take-off operational modes for yaw and longitudinal guidance
  • The A/THR function is engaged
  • At the thrust reduction altitude, the FM part warns the pilot to set the thrust levers to the CLimB gate
  • The thrust levers will not normally leave this position until a RETARD audio message tells the pilots to set the thrust levers to the IDLE gate before touch-down

AP Engagement

  • Either AP can be engaged 5 seconds after lift-off
  • Only one AP can be engaged at a time
  • After the normal climb, cruise and descent phases, the selection of automatic landing through the APProach FCU P/B lets the second AP be engaged
  • APs remain engaged to control the aircraft on the runway centerline after touchdown
  • The pilots disengage APs at low speed or when the A/C is stopped

Data Base Loading

  • The navigation and performance data base must be loaded and updated to keep the system operational
  • The navigation data base is periodically updated (every 28 days)
  • This module gives information related to the uploading and crossloading of the elements of the FM part of the FMGECs
  • The uploading is done using the Multipurpose Disk Drive Unit (MDDU)
  • The FM part of each FMGEC operates thanks to the Flight Management System (FMS) operational software, PERFormance and NAVigation data bases aid, the Operational control Configuration (OPC), and the Airline Modifiable Information (AMI) configuration files. These are mandatory loadable elements.

Uploading (with the MDDU/DLS) and Crossloading of Data to the FMGEC

  • Make sure the FM source selector is in the NORM position
  • The panel 135VU should also be in the NORM position.

Check of the Loadable Elements P/N Reference

  • The check of the P/N reference of the loadable elements is done through the applicable P/N STATUS page
  • Make sure the software P/N reference is different from the one on the floppy disk
  • To determine which elements need to be loaded: Push the DATA mode key, then select SOFTWARE STATUS/XLOAD to show the P/N XLOAD page.

Uploading of the FMGEC

  • Open one of the two FMGEC C/Bs on the RESET panel
  • Select the applicable FMGEC on the Data Loading Selector (DLS)
  • Insert the applicable disk into the MDDU and close the applicable FMGEC C/B
  • Monitor data transfer
  • Remove the disk and deselect the FMGEC via the DLS
  • Reset the loaded FMGEC
  • Verify the software P/N reference on the P/N STATUS page is identical to the one on the relevant disk

Crossloading Procedure

  • When the uploading of the first FMGEC is completed, the XLOAD function can be used for the loading of the opposite FMGEC
  • Select the appropriate FMGEC on the Data Loading Selector
  • Confirm your selection to activate the crossloading process
  • Verify that both FMGECs are no longer in independent mode operation. Ensure the amber IND annunciator and the INDEPENDENT OPERATION indication are off.

Deleting a Flight Plan from the MCDU INIT A Page

  • To carry out some maintenance actions, it is necessary to enter a basic flight plan
  • To delete such a flight plan, select the "A/C STATUS" page and select "SECOND DATA BASE", then select "SECOND DATA BASE" again
  • Verify the "ACTIVE DATA BASE" is valid (not out of date). Then press "INIT" and verify the "INIT A" page is erased

Flight Envelope General Description (3)

  • In addition to the acquisition of the aircraft parameters used by the Auto Flight System (AFS), the Flight Envelope (FE) function computes the speed envelope and detects abnormal flight conditions

Flight Envelope Protection D/O (3)

  • FE processing is autonomous
  • FE detects abnormal flight conditions such as windshear conditions and aft CG out of a tolerated limit
  • Alphafloor acquisition is available from take-off to a radio altitude of 100 feet before landing
  • The MCDU (BACK-UP NAV) is used as a backup system when both Flight Management (FM) parts fail
  • The MCDU B/UP NAV is activated by pressing "SELECT NAV B/UP" on the MCDU page
