A simulation study to determine the effect on air traffic control when both Vertical and Short Takeoff and Landing aircraft are introduced into a terminal air traffic control environment was conducted. The simulation was conducted using the Model B Dynamic Air Traffic Control Simulator. Several approach conditions, various glide slope angles, and separation criteria were investigated to determine the effect on a terminal environment. It was concluded that Vertical and Short Takeoff and Landing aircraft could be accommodated in the terminal area using present operational procedures as contained in the Terminal Air Traffic Control Manual 7110.8. However, when Vertical and Short Takeoff and Landing aircraft reduced from terminal area speed to a slow final approach speed, difficulties were encountered in providing not only the desired spacing between these aircraft but between these aircraft and conventional aircraft in the sequence to and on the final approach course. These problems did not exist when Vertical and Short Takeoff and Landing aircraft used a final approach speed compatible with that of conventional aircraft. (Author).

A study has been undertaken to define hand-ling qualities criteria for V/STOL aircraft. With the current military requirements for helicopters and airplanes as a framework, modifications and additions were made for conversion to a preliminary set of V/STOL requirements using a broad background of flight experience and pilots' comments from VTOL and STOL aircraft, BLC (boundary-layer-control) equipped aircraft, variable stability aircraft, flight simulators and landing approach studies. The report contains a discussion of the reasoning behind and the sources of information leading to suggested requirements. The results of the study indicate that the majority of V/STOL requirements can be defined by modifications to the helicopter and/or airplane requirements by appropriate definition of reference speeds. Areas where a requirement is included but where the information is felt to be inadequate to establish a firm quantitative requirement include the following: Control power and damping relationships about all axes for various sizes and types of aircraft; control power, sensitivity, d-amping and response for height control; dynamic longitudinal and dynamic lateral- directional stability in the transition region, including emergency operation; hovering steadiness; acceleration and deceleration in transition; descent rates and flight-path angles in steep approaches, and thrust margin for approach.
