FLIGHT INSTRUMENTS

The flight instruments consist of the Electronic Instrument System (EIS) and several additional

instruments. The EIS has six identical displays and is made up of two subsystems, the Electronics Flight

Instrument System (EFIS) and the Centralized Aircraft Monitor System (ECAM).

The EFIS has two displays on each side of the cockpit, Primary Flight Display (PFD) and Navigation Display

(ND). The PFD consists of:

• Aircraft attitude

• Flight director command bars

• Aircraft altitude both in MSL and AGL

• Aircraft vertical velocity and Vertical path indications

• Traffic Alert and Collision Avoidance System (TCAS)

• Indicated airspeed

• Flight Mode Annunciations (FMA)

• ILS information

The ND consists of:

• Range markers

• Flight Plan

• Navigation Aids

• TCAS information

• Heading

• Speed
