EFIS

EFIS (Electronic Flight Instrument System) replaces traditional analog flight instruments with electronic displays, forming the basis of the modern "glass cockpit." EFIS typically includes:

• PFD (Primary Flight Display): Attitude, airspeed, altitude, vertical speed, heading
• ND (Navigation Display): Map, route, weather radar, traffic
• EICAS/ECAM: Engine and systems monitoring

EFIS provides improved situational awareness, reduced workload, and greater reliability compared to mechanical instruments.
