RESULTS OF AN AIRCRAFT VISIBILITY QUESTIONNAIRE CONCERNED WITH THE ESTIMATED BENEFITS OF AIRBORNE PROXIMITY WARNING INDICATOR SYSTEMS

Approximately 3,000 questionnaires were returned from a mailing of 15,000 questionnaires to pilots whose names were drawn from the Airmen's Directory Tapes. The mailing was concentrated in 21 hubs in the continental United States. A higher proportion of pilots holding ATR and instrument ratings were sampled than commercial and private pilots without instrument ratings and students, but all were included. Many military pilots responded whose names appeared in the airmen's Directory because they also held civil ratings. The responses to the questionnaire give estimates of the incidence of various meteorological conditions in these hubs and the percent of the time that pilots holding various ratings and certificates (pilot classes) elect to fly IFR and VFR under these conditions.
