In the early days of flying, pilots relied on the eyeball, the basic T-instrument layout, and limited ATC input. This provided the real time situational awareness of the day. Analog instruments of the ‘basic T-instrument arrangement’ have since evolved into air data and inertial reference aircraft systems (avionics), as shown in Table A (right).
