A Study of Taking off and Landing an Airplane
A 1923 technical report from the NASA Technical Reports Server, a study of airplane takeoff and landing, written for aeronautical engineers and flight researchers. The pictures are plain line graphs plotting rudder, aileron, elevator, air-speed and acceleration against time in seconds, with labelled axes and traced curves. A designer might take from them the clean, dense chart style of early engineering data, with its layered wavy lines and minimal annotation.
