Abstract:

A simulator study has been made to determine the effectiveness of a single instrument presentationAS AN AID TO THE PILOT IN CONTROLLING BOTH ROTATION AND CLIMBOUT PATH IN TAKE-OFF. The instrument was basically an angle-of-attack indicat r, biased with a total-pressure-rate input as a means of suppressing the phugoid oscillation. Linearized six-degree-of-freedom equations of motion were utilized in simulating a hypothetical supersonic transport as the test vehicle. Each of several experienced pilots performed a number of simulated take-offs, using conventional flight instruments and either an angle-of-attack instrument or the combined angle-of-attack and total-pressure-rate instrument. The pilots considered the combined angle-of-attack and totalpressure-rate instrument a very effective aid. Even though they could, with sufficient practice, perform satisfactory climbouts after simulated engine failure by monitoring the conventional instruments and making corrections based on their readings, it was much easier to maintain a smooth flight path with the single combined angle-ofattack and total-pressure-rate instrument.
