Electronic Centralized Aircraft Monitor (ECAM)• The upper ECAM screen displays engine, flaps setting, fuel quantity and alert information.• The lower ECAM displays the various systems parameters.
3. Electronic Centralized Aircraft Monitor (ECAM)• ECAM also known as MFD (Multifunction Display)• ECAM monitors the overall aircraft systems, including its fuel, electrical and engine systems.• Give the pilots warning when there is a malfunction.• For example, if an engine begins to lose oil pressure, the ECAM might sound an alert, switch the display to the page with the oil system information and outline the low oil pressure data with a red box.

EFIS• With the introduction of fully integrated, computer-based navigation system, most electro/mechanical instrumentation has been replaced with TV type colour displays. The EFIS system provides the crew with two displays:•• Electronic Attitude Direction Indicator (EADI).•• Electronic Horizontal Situation Indicator (EHSI).•• The EADI is often referred to as the Primary Flight Display (PFD) and the EHSI as the Navigation Display (ND). The EADI and EHSI are arranged either side by side, with the EADI positioned on the left, or vertically, with the EADI on the top.•
• SYSTEM LAYOUT•• As is the case with conventional flight director systems, a complete EFIS installation consists of two systems. The Captain’s EFIS on the left and the First Officer’s on the right.•• The EFIS comprises the following units:•• Symbol Generator (SG).•• Display units X 2 (EADI & EHSI).•• Control Panel.•• Remote Light Sensor

EFIS DISPLAY UNITS• Each display unit consists of the following modules: – Cathode Ray Tube. – Video Monitor Card. – Power Supply Unit. – Digital Line Receivers. – Analog Line Receivers. – Convergence Card.
EADI - • Display the traditional ADI • Pitch and Roll attitude information • Altitudes and speed information. • Early EFIS - (CRT) • Later instrument (LCD)
EADI• In normal use, the EADI is coupled directly to the autopilot and the display is used by the pilot to monitor flight progress.• Alternatively, steering and attitude (pitch and roll) demand bars help the pilot to fly manually.• The EADI provide steering information to follow, for example:• a manually input heading;• a route input on the Flight Management System (FMS);• a navigation beacon (VOR, ADF, etc.);• an IRS (Inertial Reference System) track; or,• an ILS localiser.• and to:• climb or descend to a level and maintain that level on reaching;• follow an ILS glidepath; or,• follow a Go-around procedure;
EHSI (Electronic Horizontal Situation Indicator)• Electronic Horizontal Situation Indicator (EHSI)• The Electronic Horizontal Situation Indicator (EHSI) replaces a number of different instruments found on a conventional aircraft, and may be used to depict some or all of the following information:• heading flown;• heading or track selected;• bearing to or from a navigation beacon (VOR, DME);• lateral deviation from a selected track;• ground speed, distance and time to go;• aeronautical map;• weather information;• plus much more information according to design
EHSI• Display – According to the selected mode
