A common ongoing debate within the aviation community is centered around flight instruments. Specifically, the comparison between the modern glass cockpit and the ‘old school’ six pack. A glass cockpit is an aircraft cockpit that features electronic or digital flight instrument displays, and typically large LCD screens. This differs from the classic six pack, which is composed of the traditional style analog dials and gauges, nicknamed ‘steam gauges.’ The six pack, which comprises the airspeed indicator, altimeter, vertical speed indicator, attitude indicator, heading indicator, and turn coordinator, has been in use for years, and remains a good option. However, glass cockpits represent the future of aviation. This blog will explain the main differences between these modern and classic instrumentation systems.
