Introduction to EFIS
Electronic Flight Instrument System (EFIS) presents crucial flight data electronically. The Boeing 777 features advanced EFIS with integrated systems for enhanced situational awareness and safety.
Primary Flight Display
Boeing 777’s Primary Flight Display (PFD) shows attitude, airspeed, altitude, and heading. It integrates information previously shown on multiple gauges, decluttering the cockpit and improving pilot reaction time.
Navigation Display Insights
The Navigation Display (ND) maps out the flight plan, weather, traffic, and terrain. A key innovation in the 777’s ND is its ability to overlay route data with actual physical geographic features.
Engine Indication and Crew Alerting System
EICAS displays engine performance and aircraft system information. Unique to the 777, it auto-prioritizes alerts, ensuring pilots focus on the most critical issues first, an industry-leading safety enhancement.
Electronic Checklist Integration
The Boeing 777 incorporates an electronic checklist system. It directly interacts with onboard systems, automatically completing routine checks and highlighting discrepancies, reducing pilot workload significantly.
Fly-By-Wire Technology
Boeing 777 uses advanced fly-by-wire controls, integrated with the EFIS. This technology provides smoother, more precise handling and automates certain responses, enhancing flight efficiency and safety.
Advanced Situation Awareness
The 777’s EFIS includes the Synthetic Vision System (SVS), providing a 3D graphical representation of terrain. This system significantly improves pilots’ situational awareness, particularly in challenging visibility conditions.
