- rapidly as possible. It is of particular importance that further knowledge should be sought on the probabilities of association of extreme turbulence with predictable meteorological conditions, so that the likelihood of such turbulence can itself be predicted. The development of a generally acceptable scale of measurement of the severity of turbulence, and of a standard nomenclature for the various types of turbulence, would also be valuable as a possible product of further study. It is hoped that research in this field may receive a high priority with the Weather Bureau, the National Advisory Committee for Aeronautics, and such other governmental and private agencies as may have special interest in the problem or special qualifications to deal with it.
- Methods should be developed for collecting and correlating the experiences that airplane pilots may have with exceptional turbulence, or other unusual atmospheric conditions. It happens from time to time that a pilot, military, airline, or private, observes some exceptional atmospheric condition, or some exceptional effect upon the flight of the aircraft. The ability of pilots to benefit from one another's experiences in such matters is quite largely limited to the results of informal report. It would be of great value in connection with continued research on atmospheric structure and its effect on aircraft if records of all such exceptional experiences could be brought into the hands of a single agency, for comparison and the development of such generalized conclusions as the collected mass of data may allow. The National Advisory Committee for Aeronautics has already made progress along this line, with specific reference to the magnitude of the accelerations of aircraft in turbulent air and to the conditions noted by pilots
