    Integration of STOL airplanes into the ATC system (1972)
    In:  CASI
    Details
    Publication Date: 2006-03-27
    Description: The study involving the STOL airplane and air traffic control is a joint NASA/FAA effort designed to examine the effects of introducing large numbers of STOL airplanes into a high-density terminal area. Simply stated, the objectives of the study are to determine the effects of the STOL airplane on the air traffic control (ATC) system and to determine the effects of the ATC system on the STOL airplane. More specifically, the study seeks to determine the airspace requirements and air traffic control equipment and handling techniques required to accommodate the STOL airplane in the ATC system and the design characteristics, avionics equipment, and flight procedures required to operate the STOL airplane in the air traffic control system.

    Revised tables of airspeed, altitude, and Mach number presented in the International system of units (1973)
    In:  CASI
    Details
    Publication Date: 2019-06-27
    Description: Because inception of a national program to implement the International System of Units (SI) appears to be inevitable and imminent, the tables of airspeed, altitude, and Mach number prepared by Livingston and Gracey to serve for airspeed meter and altimeter calibrations and for the conversion of flight measurements of these quantities to related parameters - Mach number, true airspeed, equivalent airspeed, etc. - have been revised to the SI. Tables of airspeed in knots are also included because of the significance of this quantity in navigation. In addition, the data in the altitude tables have been revised to the U.S. Standard Atmosphere of 1962. The latter data reflect increased knowledge of the higher atmosphere and more precise determination of basic quantities, including the redefinition of the absolute thermodynamic temperature scale by the Tenth General Conference on Weights and Measures in 1954. The U.S. Standard Atmosphere, 1962, corresponds to the International Civil Aviation Organization (ICAO) Standard Atmosphere up to 20 kilometers (geopotential altitude). A table of conversion factors for various pressure units is presented in SI Units.

    Airport-area airspace used in simulated operations with an experimental powered-lift STOL airplane (1973)
    In:  CASI
    Details
    Publication Date: 2019-06-27
    Description: Simulation tests were made using an experimental powered-lift STOL airplane to help define airport-area airspace requirements for STOL operations. The operational feasibility and airspace used in take-offs followed by climbing turns, offset (bent localizer) approaches, missed approaches, and two-segment (bent glide-slope) approaches were studied. Flight-director guidance was provided for the approach maneuvers.

    A flight investigation with a STOL airplane flying curved, descending instrument approach paths (1974)
    In:  CASI
    Details
    Publication Date: 2019-06-27
    Description: A flight investigation using a De Havilland Twin Otter airplane was conducted to determine the configurations of curved, 6 deg descending approach paths which would provide minimum airspace usage within the requirements for acceptable commercial STOL airplane operations. Path configurations with turns of 90 deg, 135 deg, and 180 deg were studied; the approach airspeed was 75 knots. The length of the segment prior to turn, the turn radius, and the length of the final approach segment were varied. The relationship of the acceptable path configurations to the proposed microwave landing system azimuth coverage requirements was examined.

    Terminal-area flight procedures and route design for supersonic transport New York-transatlantic operations (1972)
    In:  CASI
    Details
    Publication Date: 2019-06-27
    Description: The results of an analytical investigation of two departure and arrival transition procedures between John F. Kennedy International Airport and projected North Atlantic track systems for supersonic transport (SST) operations are presented. The procedures studied were: (1) separated departure and arrival transition routes with departures made at supersonic speeds, and (2) superimposed departure and arrival routes with departures restricted to subsonic speed until the airplane is on the track system. For both procedures, transition routes with intercept angles of 30 deg to 90 deg to both six-and four-track systems were investigated. Track spacings of 30 and 60 nautical miles were studied.

    Simulation studies of STOL airplane operations in metropolitan downtown and airport air traffic control environments (1974)
    In:  CASI
    Details
    Publication Date: 2019-06-27
    Description: The operating problems and equipment requirements for STOL airplanes in terminal area operations in simulated air traffic control (ATC) environments were studied. These studies consisted of Instrument Flight Rules (IFR) arrivals and departures in the New York area to and from a downtown STOL port, STOL runways at John F. Kennedy International Airport, or STOL runways at a hypothetical international airport. The studies were accomplished in real time by using a STOL airplane flight simulator. An experimental powered lift STOL airplane and two in-service airplanes having high aerodynamic lift (i.e., STOL) capability were used in the simulations.

    A fixed-base simulation study of two STOL aircraft flying curved, descending instrument approach paths (1973)
    In:  CASI
    Details
    Publication Date: 2019-06-27
    Description: A real-time, fixed-base simulation study has been conducted to determine the curved, descending approach paths (within passenger-comfort limits) that would be acceptable to pilots, the flight-director-system logic requirements for curved-flight-path guidance, and the paths which can be flown within proposed microwave landing system (MLS) coverage angles. Two STOL aircraft configurations were used in the study. Generally, no differences in the results between the two STOL configurations were found. The investigation showed that paths with a 1828.8 meter turn radius and a 1828.8 meter final-approach distance were acceptable without winds and with winds up to at least 15 knots for airspeeds from 75 to 100 knots. The altitude at roll-out from the final turn determined which final-approach distances were acceptable. Pilots preferred to have an initial straight leg of about 1 n. mi. after MLS guidance acquisition before turn intercept. The size of the azimuth coverage angle necessary to meet passenger and pilot criteria depends on the size of the turn angle: plus or minus 60 deg was adequate to cover all paths execpt ones with a 180 deg turn.
