In an effort to increase the safety of
operating complicated aircraft, computers and
computer systems have been incorporated.
Flight instrumentation, engine and
airframe monitoring are areas particularly well
suited to gain advantages from the use of
computers.
They contribute by helping to reduce
instrument panel clutter and focusing the
pilot’s attention only on matters of imminent
importance

On the flight deck, the display units are the most obvious parts of an
EFIS system, and are the features which give rise to the name ”glass
cockpit".
The display unit taking the place of the ADI is called the Primary Flight
Display (PFD). If a separate display replaces the HSI (Horizontal
Situated Indicator), it is called the Multi Function
Display(MFD)/Navigation Display.
MFDs can also display information about aircraft systems, such as fuel
and electrical systems (see EICAS, below). As with the PFD, the MFD can
change the color or shape of the data to alert the aircrew to hazardous
situations.
• A MFD displays an EHSI that presents navigational information for the entire
flight. The pilot selects the mode most useful for a particular phase of flight,
ranging from navigational planning to instrument approach to landing. The MAP
mode is used during most of the flight
Engine Indications and Crew Alerting System (EICAS)/
Electronic Centralized Aircraft Monitoring (ECAM)
• The pilots are provided with controls, with which they select display
range and mode (for example, map or compass rose) and enter data
(such as selected heading).
Where inputs by the pilot are used by other equipment, data buses
broadcast the pilot's selections so that the pilot only needs to enter the
selection once. For example, the pilot selects the desired level-off
altitude on a control unit. The EFIS repeats this selected altitude on the
PFD and by comparing it with the actual altitude (from the air data
computer) generates an altitude error display. This same altitude
selection is used by the automatic flight control system to level off, and
by the altitude alerting system to provide appropriate warnings.
