Which display is part of the "glass cockpit" approach?

The Primary Flight Display (PFD) is a crucial component of the "glass cockpit" design, which represents a significant advancement in aircraft instrumentation. Unlike traditional cockpits that utilize a series of mechanical gauges, a glass cockpit consolidates vital flight information into a few digital displays, bringing enhanced situational awareness and streamlining pilot interaction.

The PFD typically presents a wealth of information, including airspeed, altitude, heading, vertical speed, and other essential flight parameters, all in a unified visual format. This integration allows pilots to quickly assimilate information and make more informed decisions, improving overall flight safety and efficiency. Advanced features of the PFD may also include flight path indicators, traffic alerts, and navigation data, enhancing the pilot's ability to manage the aircraft effectively.

The other components mentioned, such as the altimeter, heading indicator, and artificial horizon, while important flight instruments, reflect traditional analog designs rather than the integrated approach characteristic of glass cockpit technology. These instruments may still be found in glass cockpit systems, often as backups or supplementary information, but they do not represent the modern, streamlined interface aimed at improving pilot workload and situational awareness like the PFD does.
