The cockpit, or flight deck, is the area in an aircraft from which the pilot controls the aircraft. It contains the flight instruments on an instrument panel, as well as the controls that allow the pilot to fly the aircraft. While every cockpit features dozens of instruments, there are a few that are more important than others. These instruments are the airspeed indicator, altitude indicator, altimeter, vertical speed indicator, heading indicator, and turn coordinator. Together, these instruments are known as the ‘six pack’ and make up the most basic instruments found in virtually all aircraft cockpits. The six pack was first established by the Royal Air Force in 1937, but has since been adopted worldwide. This blog will explain each of the six pack instruments and their functions.
