What is a glass cockpit and what are its advantages over traditional instruments?

A glass cockpit uses electronic displays (LCD/LED) instead of mechanical instruments to present flight information. Primary components include: Primary Flight Display (PFD) showing attitude, airspeed, altitude, and heading; Multi-Function Display (MFD) for navigation, systems, and weather; and Engine Indication and Crew Alerting System (EICAS/ECAM). Advantages include: Improved situational awareness through integrated information, Easier scanning with consolidated displays, Configurable formats, Reduced weight and improved reliability, Easier updates, and Enhanced warning systems. Modern aircraft universally use glass cockpits (Boeing 777, A320 and later).
