1960Aeroplane XCVIII. 764/1 Airborne experience with the Smiths Para-Visual Director system will leave the newcomer with a strong conviction that this new flight-director/instrument-flying concept must inevitably alter present ideas about weather minima and automatic-landing prospects. 1964M. Allward Inside Jet Airliner vii. 53 Three little instruments called Para-Visual Directors mounted in line along the top of the instrument panels in front of each pilot. 1968G. D. P. Worthington Airline Instrument Flying xvi. 256 The Para-visual Director is designed to apply command information in regard to pitch and bank through a rotating ‘barber's pole’ display which is so located that it is within the pilot's general field of vision but outside the limits of his direct field of vision. The direction of rotation of the pole applies a signal in the pilot's peripheral field of vision which demands fly up or fly down in the case of the pitch bars, or fly left or fly right in the case of the bank presentation. |
