Abstract : Automatic throttles, take-off information displayed on the flight director, and go-around information displayed on the flight director, all using angle-of-attack as the primary control reference, were evaluated in a DC-7 aircraft. Phototheodolite position data and oscillograph recordings from an on-board recorder were used to measure performance. It was concluded that the automatic throttles were compatible with flight director approaches and with landings performed with the aircraft automatic landing system. The go-around information was used to perform go-around without reference to attitude or airspeed. Four engine and three engine take-offs were performed with conventional instruments and with the flight director. Performance was more consistent when the flight director was used. (Author)
