AUTOFLIGHT MENU Flight management (A) 1/70 AUTOFLIGHT MENU Flight management (A) 2/70 To enable the FG part of the FMGS to guide the aircraft along a route, you must first program the flight plan into the MCDU. In this module, we will do this together and in the process learn about the organization, functions and indications of the MCDU. We will then see how the flight plan itself is displayed for you on the MCDU and compare it to what you see on the ND. PARIS (ORLY) CCAAIIRROO AUTOFLIGHT MENU Flight management (A) 3/70 Before we begin to program the flight plan, lets look at the functions, controls and displays of the MCDU. AUTOFLIGHT MENU Flight management (A) 4/70 AUTOFLIGHT MENU Flight management (A) 5/70 First, the brightness knob. We will increase the brightness for you. Notice the knob is labeled BRT. AUTOFLIGHT Flight management (A) 6/70 We will divide the MCDU into two parts: - The upper part contains the display and some keys which are oriented to specific lines on the display. MENU AUTOFLIGHT MENU Flight management (A) 7/70 - The lower part contains a number key pad, a letter keyboard and some function keys. Let’s have a closer look. AUTOFLIGHT MENU Flight management (A) 8/70 On the screen, the first line gives the name of the current display or page. MCDU MENU is the first page displayed at power-up. It is a menu for the various systems which can be accessed by the MCDU. Notice the first system on the list is the FMGC. MCDU 1 will access FMGC 1 while MCDU 2 will access FMGC 2. All listed systems use the MCDU as a common interface. AUTOFLIGHT MENU Flight management (A) 9/70 Six keys, called Line Select keys abbreviated LSK, are located on either side of the screen. AUTOFLIGHT MENU Flight management (A) 10/70 The LSKs are numbered from 1 to 6 from the top to bottom. For example, the LSK used to access the FMGC is called the LSK 1 L, where L stands for left.

For example, the LSK used to access the FMGC is called the LSK 1 L, where L stands for left. Noo,, cclliicckk oonn tthhee LLSK11 LLeefftt.. 1 2 3 4 5 6 1 2 3 4 5 6 Left Right AUTOFLIGHT MENU Flight management (A) 13/70 You have accessed the FMGC Status Page. Several items of information are displayed. Among them you can find the type of aircraft and the engines used. Notice the color coding used. White indicates a title or a label while blue indicates a modifiable value. Green indicates a value which cannot be modified. This color coding is used throughout all the pages of the MCDU, there are more colors which will be explained as we encounter them. AUTOFLIGHT MENU Flight management (A) 14/70 Let’s talk a little more about the page layout. A page can display 14 lines of text. There is: - One title line, here “A320-200”, the aircraft type, - 6 label lines, one for each data line, our example being ENG. - 6 data lines, e.g “IAE-V2500-AX” - And a scratchpad line at the bottom of the screen. You will see how to use the scratchpad later in the module. AUTOFLIGHT MENU Flight management (A) 15/70 The Flight Management system, or FM, uses two databases to perform its computations, a Navigation Data Base and a Performance Data Base. AUTOFLIGHT MENU Flight management (A) 16/70 The Navigation Data Base, or Nav Data Base, contains all the necessary information for the lateral flight plan, such as routes, airways, VORs, NDBs, waypoints and airports. AUTOFLIGHT MENU Flight management (A) 17/70 The navigation database is updated every 28 days and its currency and validity is checked on this page during the preflight. Notice there is an active database and a secondary or second data base. AUTOFLIGHT MENU Flight management (A) 18/70 The secondary (second) data base is either the previous or the next data base. Data bases are loaded two at a time so that if the first one expires away from a maintenance base, the pilot can activate the second one before departure the next day. AUTOFLIGHT MENU Flight management (A) 19/70 The Performance Data Base, or Perf Data Base, contains the aircraft performance model and is used to optimize the flight plan and to obtain predictions such as ETA’s, EFOB etc... AUTOFLIGHT MENU Flight management (A) 20/70 The PERFormance FACTOR is used to modify the aircraft performance model for the individual aircraft. The value 0.0 in percentage units is in blue indicating that it can be modified. AUTOFLIGHT MENU Flight management (A) 21/70 We will see now how to select the other pages of the autoflight system. Most of the pages are accessed using the function keys. AUTOFLIGHT MENU Flight management (A) 22/70 In the FMGS preflight the first thing that we do is confirm the correct information on the Status Page. We are then ready to begin programming the route of flight, this is called Initializing the flight plan. Caallll IINIITT ppaaggee.. AUTOFLIGHT MENU Flight management (A) 23/70 In the FMGS preflight the first thing that we do is confirm the correct information on the Status Page.

AUTOFLIGHT MENU Flight management (A) 24/70 In the FMGS preflight the first thing that we do is confirm the correct information on the Status Page. We are then ready to begin programming the route of flight, this is called Initializing the flight plan. Noo,, pprreessss tthhee IINIITT kkeeyy.. AUTOFLIGHT MENU Flight management (A) 25/70 The INIT page is the first page on which you input data. Notice the amber boxes; these are the fields into which data must be inserted. Notice the fields with white dashes, these fields are not yet available to fill or display information because the FMGC does not have enough information. As we proceed and provide information to compute the lateral and vertical components of the flight plan, we will see these fields become active. The field on the bottom right is the default altitude for the tropopause. The cyan color means it is modifiable, if we make no input the FMGC will use this default for its performance computations. AUTOFLIGHT MENU Flight management (A) 26/70 Notice the two fields COmpany RouTE, or CO RTE, and FROM/TO on the first line. They are used to define all or some of the flight plan and associated parameters. AUTOFLIGHT MENU Flight management (A) 27/70 The first step in creating the flight plan is to define the origin and destination. This can be done in two different ways: - either by inserting the four letter ICAO airport codes in the FROM/TO field, - or inserting a specific Company Route (CO RTE) which will actually insert the entire route from the Nav Database. AUTOFLIGHT MENU Flight management (A) 28/70 We will use the CO RTE option to set up a flight from Paris-Orly (ORY) to Cairo (CAI). The CO RTE, ORYCAI1, is written in the scratchpad at the bottom of the screen using the keypad of the MCDU. PARIS (ORLY) CCAAIIRROO AUTOFLIGHT MENU Flight management (A) 29/70 The CO RTE is inserted in the system by pressing the LSK 1L. Plleeaassee ddoo iitt nnoow..

AUTOFLIGHT MENU Flight management (A) 32/70 Most of the fields of the INIT page are filled using information from the Nav Data base e.g.: - LAT/LONG, - COST INDEX, - CRZ FL/ISA TEMP, - ALTN. Notice that all the fields are in cyan indicating that you can modify them. AUTOFLIGHT MENU Flight management (A) 33/70 The LAT/LONG is for the departure airport Orly. The coordinates are for the airport reference as shown on your charts. You will learn to modify them in the FMGS trainer to the actual gate position. AUTOFLIGHT MENU Flight management (A) 34/70 The position displayed is used as a reference for the alignment of the Inertial Reference System. It is sent to the IRSs by selecting the LSK 3R, corresponding to the ALIGN IRS prompt. AUTOFLIGHT MENU Flight management (A) 35/70 You will see the full IRS alignment in detail in the Navigation modules later in the course, so we have jumped ahead to the next step after full IRS alignment. AUTOFLIGHT MENU Flight management (A) 36/70 Let’s go to the flight plan page to see the flight plan itself. Caallll FF--PLLN ppaaggee..

AUTOFLIGHT MENU Flight management (A) 38/70 Let’s go to the flight plan page to see the flight plan itself. Noo,, pprreessss tthhee FF--PLLN kkeeyy.. AUTOFLIGHT MENU Flight management (A) 39/70 This is the F-PLN page. It can be thought of as an electronic “scroll or roll-pad” containing all the waypoints of the flight. AUTOFLIGHT MENU Flight management (A) 40/70 Notice the symbols. They indicate that the “pad” can be scrolled using these two keys, called the slew keys. AUTOFLIGHT MENU Flight management (A) 41/70 The F-PLAN page is capable of displaying the ETA, speed and altitude for each waypoint of the flight plan. Notice the white dashes, this is because there is insufficient information to calculate the values until we made further inputs. AUTOFLIGHT MENU Flight management (A) 42/70 Notice the symbol in the upper right corner of the display, it indicates that you can access another page using the NEXT PAGE key. Caallll tthhee NEXTT ppaaggee..

AUTOFLIGHT MENU Flight management (A) 44/70 Notice the symbol in the upper right corner of the display, it indicates that you can access another page using the NEXT PAGE key. Noo,, pprreessss tthhee NEXTT PAGE kkeeyy.. AUTOFLIGHT MENU Flight management (A) 45/70 NEXT PAGE key is like a toggle pb used to navigate between two pages when they are available. In this case, the pages are called FPLAN A and F- PLAN B. AUTOFLIGHT MENU Flight management (A) 46/70 The two flight plan pages are the same except the TIME is replaced by EFOB and ETA is replaced by WIND. AUTOFLIGHT MENU Flight management (A) 47/70 The destination information is displayed at the bottom of the flight plan page regardless of the number of waypoints. AUTOFLIGHT MENU Flight management (A) 48/70 Let’s look at the color coding used for the waypoints. The white one, here D086C is the waypoint to which we will fly. Hence, it is called the TO waypoint. It is white in order to differentiate it from the other waypoints. All the other waypoints are green between the departure and destination, except the destination airport which is white. AUTOFLIGHT MENU Flight management (A) 49/70 Let’s compare the flight plan on the MCDU with what is displayed on the ND. D086C is also displayed there in white as the TO waypoint. Bearing and distance to go are also displayed in both places. AUTOFLIGHT MENU Flight management (A) 50/70 LFPO 08 is the takeoff runway. Notice that it is displayed in green on the MCDU but in white on the ND. The waypoint just above the TO waypoint is called the FROM waypoint. In flight we constantly travel between the FROM and TO waypoints. AUTOFLIGHT MENU Flight management (A) 51/70 The waypoint following the TO waypoint is called the NEXT waypoint. Notice that you can read a bearing to the TO waypoint, and a track from the TO to the NEXT waypoints. AUTOFLIGHT MENU Flight management (A) 52/70 LLeett’’ss cchhaannggee tthhee ND ttoo PLLANmooddee..

AUTOFLIGHT MENU Flight management (A) 55/70 AUTOFLIGHT MENU Flight management (A) 56/70 Remember, the PLAN mode is north oriented. It is always centered on the second line of the F-PLN page display. This enables you to scroll along the flight plan and see all the waypoints along the route. AUTOFLIGHT MENU Flight management (A) 57/70 This mode is very convenient to check the FPLN shown on the ND against the ATC flight plans and navigation charts. Let’s scroll the MCDU F-PLN.

Noo,, cclliicckk oonn tthhee ddoownn ssccrroollll aarrrroow.. AUTOFLIGHT MENU Flight management (A) 60/70 As you can see, the waypoint centered on the ND is always the one displayed on the second line of the MCDU. Note: We can now see the track or course to the third waypoint on the MCDU. In this way we can check the course between each set of waypoints in the flight plan against the chart if we wish. AUTOFLIGHT MENU Flight management (A) 61/70 As a result of the scroll, LFPO 08 is no longer displayed. It is replaced by the TO waypoint. At the same time, notice the FROM indication is removed from the MCDU. AUTOFLIGHT MENU Flight management (A) 62/70 Notice the symbol displayed just after the waypoint D804. This indicates that an overfly of the waypoint. An overfly means that the aircraft will not commence the turn to the new course until directly overhead the waypoint. Without the overfly condition, the FMGC will begin the turn to the new track before the waypoint for smoothness and to stay within the lateral limits of the course. AUTOFLIGHT MENU Flight management (A) 63/70 You can program the overfly of a waypoint by using this key. Then, select the waypoint to overfly using the corresponding LSK. You will see how to do this in the system trainer. AUTOFLIGHT MENU Flight management (A) 64/70 Notice the amber line. It is the Engine Out Standard Instrument Departure, or EO SID. In normal operation, it is only displayed in PLAN mode for review, or in any NAV mode if an engine fails. Engine out SIDs will be discussed in more detail later on in the course. AUTOFLIGHT MENU Flight management (A) 65/70 We saw earlier that we can scroll the flight plan using the arrow keys. In many cases it is important to jump ahead to the next airport to see the approach or the missed approach. To do this we press the AIRPORT KEY. Seelleecctt tthhee AIIRPORTT kkeeyy.. AUTOFLIGHT MENU Flight management (A) 66/70 We saw earlier that we can scroll the flight plan using the arrow keys.

AUTOFLIGHT MENU Flight management (A) 68/70 Notice on the MCDU as well as on the ND we see the approach to the destination. If we push the key again we will cycle the MCDU and associated ND to the alternate (ALTN) airport. If we push it again we will jump to where we began, the departure airport. AUTOFLIGHT MENU Flight management (A) 69/70 On the first press, the page displayed reverts to FPLN page A, with the destination airport, here HECA on the fourth line. 23R is the selected runway. AUTOFLIGHT MENU Flight management (A) 70/70 In this module we have looked at the MCDU display, the LSK’s, and some of the function keys. In the next module, we will see more functions of the flight management, as accessed through the MCDU. Module completed.
