Book Description
An evaluation has been made of a number of altitude-measuring methods based on the measurement of such quantities as gravity, acceleration, atmospheric pressure and density, cosmic-ray and magnetic-field intensities, capacitance, and radio and sound-wave propagation. From this evaluation it has been concluded that, for high-speed, high-altitude cruise operation, only the most accurate of the full-range pressure-measuring instruments, the static-pressure compensator-computer system, meets the plus or minus 250-foot system-accuracy requirement for 1,000-foot separations for the complete altitude range up to 70,000 feet. If selected units of this electromechanical computer are incorporated in a system utilizing the best of the service-type static-pressure installations, and if both of these components are calibrated by the most accurate of the presently available techniques, it appears possible to achieve a system accuracy of plus or minus 200 feet at an altitude of 70,000 feet. In the event of electrical power failure in the computer system, a full-range mechanical-type altimeter incorporating the precision-type mechanism can provide a satisfactory order of accuracy for standby operation, provided corrections are manually applied for the altimeter-scale and static-pressure errors. From the standpoint of providing minimum static-pressure errors at supersonic speeds, a minimum effect of angle of attack, and a high order of repeatability of the errors over a long period of time, it is believed that a static-pressure tube located ahead of the most forward part of the airplane will provide the optimum static-pressure installation. To achieve the highest order of accuracy with pressure altimetry, it will be advisable to standardize the apparatus and techniques used for the calibration of the pressure-measuring instruments and the static-pressure installations.

Book Description
This report reviews in detal the sources of error that may enter into the measurement of airspeed by pitot-static methods. Methods of flight calibration of airspeed installations are given. Special attention is given to the problem of accurate measurement of Mach number, air temperature, and true airspeed during high-speed maneuvers. This report also contains an extensive bibliography.
