The Test and Evaluation Branch of the United States Air Force Instrument Pilot Instructor School (IPIS) conducted an evaluation of a modified T-38 Attitude Director Indicator/Horizontal Situation Indicator (ADI/HSI) lighting system proposed by the Deputy for Materiel, Moody AFB, Georgia. The modification specified removal of a 0.25 ohm resistor from the ADI/HSI lighting system. For evaluation purposes, five T-38 front and back sea ADI/HSI lighting systems were modified. The modified aircraft were then scheduled with unmodified T-38s for night flying. Subject pilots were not made aware that modifications had been completed on any aircraft to avoid biased questionnaires. Eighty-five subjective questionnaires were completed by a diversified group of student instructor pilots and instructor pilots. Ten pilots of this group flew the modified aircraft. (Author)
