ELECTRONIC INSTRUMENT MENU System presentation 1/32 ELECTRONIC INSTRUMENT MENU System presentation 2/32 ELECTRONIC INSTRUMENT MENU System presentation 3/32 In comparison to old technology aircraft, the flight deck on the A320 is designed to be a comfortable uncluttered environment in which to work. By utilizing modern electronic display units, the presentation of information to the pilots has been improved. ELECTRONIC INSTRUMENT MENU System presentation 4/32 The Electronic Instrument System, (EIS), consists of six identical full color cathode ray tube display units. The EIS is divided into two subsystems: • the Electronic Flight Instrument System, (EFIS), for which each pilot has two displays, • the Electronic Centralized Aircraft Monitoring system, (ECAM), which uses the two displays in the center to provide information on the aircraft systems. Let’s look at the EFIS system first. ELECTRONIC INSTRUMENT MENU System presentation 5/32 PFD1 ND1 ND2 PFD2 Flight parameters are displayed on Primary Flight Displays (PFD) while Navigation data is displayed on Navigation Displays (ND). ELECTRONIC FLIGHT INSTRUMENT SYSTEM ELECTRONIC INSTRUMENT MENU System presentation 6/32 Outboard of the PFD, there are control knobs to adjust the brightness of the associated PFD and ND, or to turn the display off. ELECTRONIC INSTRUMENT MENU System presentation 7/32 A switch is provided to allow the information on the PFD and ND displays to be transferred. The use of this switch will be explained in the EIS reconfiguration module. ELECTRONIC INSTRUMENT MENU System presentation 8/32 ELECTRONIC CENTRALIZED AIRCRAFT MONITORING The two displays in the center are dedicated to the Electronic Centralized Aircraft Monitoring system (ECAM). At this stage we will simply introduce the ECAM displays and associated controls. In later modules, the ECAM system will be studied in detail. ELECTRONIC INSTRUMENT MENU System presentation 9/32 Engine/Warning Display System Display The upper ECAM display is known as the Engine Warning Display (E/WD). The lower ECAM display is known as the System Display (SD). It is on this screen that various aircraft system parameters can be viewed by the pilots. As an example, we will cycle through the system pages for you. ELECTRONIC CENTRALIZED AIRCRAFT MONITORING ELECTRONIC INSTRUMENT MENU System presentation 10/32 The presentation of system information is based on a “Need to Know” philosophy. This means that only the system information relevant to the particular phase of flight is presented to the pilots. You will see this demonstrated in the Normal and Abnormal operation modules. ELECTRONIC CENTRALIZED AIRCRAFT MONITORING Engine/Warning Display System Display ELECTRONIC INSTRUMENT MENU System presentation 11/32 Another philosophy that is used on the Flight Deck is the “Lights Out” principle. What this means is that when the aircraft is in its normal flight state there will be no white lights illuminated in any of the switches on the overhead panel. As an example, just before take off if you look up at the overhead panel, there should be no white lights illuminated on any of the switches. Let’s look at some switches and show the different possibilities. ELECTRONIC INSTRUMENT MENU System presentation 12/32 NNoorrmmaallooppeerraattiioonnccoonnffiigguurraattiioonn-- lliigghhttoouuttppoossiittiioonn SSyysstteemmddeeaaccttiivvaatteedd AABBNNOORRMMAALLFFaauulltt iinnddiiccaattiioonn For the majority of the switches on the overhead panel, the push button switch logic is; • Normal operation configuration - No light showing, (the LIGHTS OUT philosophy). • Abnormal condition - Amber FAULT light (this assists identification of the switch associated with an abnormal condition). • Non lights out switch position - White light. If normally the system should be operating and is deactivated a white OFF light is illuminated. If normally the system should not be operating and is activated a white ON light is illuminated. SSyysstteemmaaccttiivvaatteedd ELECTRONIC INSTRUMENT MENU System presentation 13/32 There are some switches on the overhead panel which are used on a temporary basis or may have an indication of their state. The logic is; • Temporary selection for operational reasons - Blue ON light e.g. anti-ice • Applicable system status - Green light - e.g. APU available. You will see this philosophy demonstrated throughout the course. TTeemmppoorraarriillyysseelleecctteeddsswwiittcchh AApppplliiccaabblleessyysstteemmssttaattuuss ELECTRONIC INSTRUMENT MENU System presentation 14/32 Below the ECAM displays, on the center pedestal, is the ECAM control panel. The two controls on the left hand side are to adjust the brightness of the two ECAM screens or to turn them off. We will look at the rest of the controls on this panel in more detail later. ELECTRONIC INSTRUMENT MENU System presentation 15/32 Just below the ECAM screens, on the pedestal, is a switching panel for use in abnormal situations to restore data to the EFIS and ECAM displays. You will use this panel in the EIS Reconfiguration module. ELECTRONIC INSTRUMENT MENU System presentation 16/32 In front of each pilot there are two attention getters, a red MASTER WARNING, and an amber MASTER CAUTION. As a further means of getting the pilots attention, there is a loudspeaker on each side of the cockpit for aural alerts and voice messages. Note; The loudspeakers can also be used to listen to ATC and the intercom. ELECTRONIC INSTRUMENT MENU System presentation 17/32 ADIRS DATA DMC1 DMC3 DMC2 NAV DATA Now, let’s go back to the EFIS system. For the EFIS displays, data from the Air Data and Inertial Reference System (ADIRS) plus Navigation data from the Flight Management and Guidance System (FMGS) is fed directly to three Display Management Computers (DMC). ELECTRONIC INSTRUMENT MENU System presentation 18/32 ADIRS DATA NAV DATA The three identical DMC process the data and generate the images to be displayed. Under Normal circumstances: • DMC1 supplies EFIS information to the Captains’ PFD and ND • DMC2 supplies the First Officers’ PFD and ND. • DMC3 is available as a backup. You will see the use of DMC3 in the abnormal operation module. BACKUP DMC1 DMC3 DMC2 ELECTRONIC INSTRUMENT MENU System presentation 19/32 Now, let’s look at the other EIS sub-system, ECAM, and how the ECAM displays get their data. Sensors are fitted throughout the aircraft to monitor the various systems, including system controls operated in the flight deck. AIRCRAFT SYSTEM SENSORS ELECTRONIC INSTRUMENT MENU System presentation 20/32 DMC 3 Data for certain parameters, for example Fuel Quantity and Primary Engine Indications, is routed directly from the system sensors to the three DMC. Note that there are separate channels within each DMC for ECAM and EFIS. AIRCRAFT SYSTEM SENSORS DMC1 DMC3 DMC2 ECAM EFIS ELECTRONIC INSTRUMENT MENU System presentation 21/32 AIRCRAFT SYSTEM SENSORS For the majority of the systems the sensors supply data to 2 System Data Acquisition Concentrators (SDAC). The SDAC acquire system data, process it, and send System page data to the 3 DMC. SDAC1 SDAC2 DMC1 DMC3 DMC2 ELECTRONIC INSTRUMENT MENU System presentation 22/32 AIRCRAFT SYSTEM SENSORS Normally: • DMC 1 supplies the E/WD, • DMC2 supplies the SD, • DMC 3 is available as a backup. SDAC1 SDAC2 DMC1 DMC3 DMC2 BACKUP ELECTRONIC INSTRUMENT MENU System presentation 23/32 AIRCRAFT SYSTEM SENSORS FWC1 SDAC1 SDAC2 FWC2 DMC1 DMC3 DMC2 Two identical Flight Warning Computers (FWC) receive data from: • the aircraft system sensors to generate red Warnings, • the SDAC to generate amber Cautions. ELECTRONIC INSTRUMENT MENU System presentation 24/32 AIRCRAFT SYSTEM SENSORS FWC1 SDAC1 SDAC2 DMC1 DMC3 DMC2 FWC2 The FWC then supply; • the DMC for the display of alert messages, • the attention getters, • the loudspeakers for aural alerts and synthetic voice messages. ELECTRONIC INSTRUMENT MENU System presentation 25/32 AIRCRAFT SYSTEM SENSORS FWC1 SDAC1 SDAC2 DMC1 DMC3 DMC2 FWC2 ELECTRONIC INSTRUMENT MENU System presentation 26/32 All the components shown can be collectively called the ECAM system. We will study the use of the ECAM system in a separate module. ELECTRONIC INSTRUMENT MENU System presentation 27/32 In addition to EFIS and ECAM, time measurement devices are provided. The master time reference for all aircraft systems is provided by a clock, located on the right lower side of the main panel. In this example the time is 1328. ELECTRONIC INSTRUMENT MENU System presentation 28/32 The time is also displayed at the bottom of the System Display. ELECTRONIC INSTRUMENT MENU System presentation 29/32 Adjustment of the time is achieved by using the UTC selector and the SET knob. You will have the opportunity to do this in the simulator. ELECTRONIC INSTRUMENT MENU System presentation 30/32 The SET knob can also be pressed to display date information, in the order month then day. In this example the date is July 4th. ELECTRONIC INSTRUMENT MENU System presentation 31/32 There are chronograph and elapsed time facilities on the clock. These functions will be covered later. ELECTRONIC INSTRUMENT MENU System presentation 32/32 In this module we have introduced you to the Electronic Instrument System, (with its two sub sections EFIS and ECAM), and the clock. In the next modules we will concentrate mainly on the ECAM system and then later in the course return to look at the EFIS displays in greater detail.
