What is EFIS?

EFIS stands for Electronic Flight Instrument System. It's a cockpit display system that presents flight data electronically, replacing traditional mechanical instruments. EFIS typically includes Primary Flight Displays (PFDs) and Multi-Function Displays (MFDs), which show information like airspeed, altitude, heading, attitude, engine parameters, and navigation data. EFIS improves situational awareness, reduces pilot workload, and enhances safety.
