Development of Computer-Generated Phenograms to Forecast Regional Conditions Hazardous to Low-Flying Aircraft.

Abstract

The seasonal distribution of all North American gull species as derived from banding data and Christmas Bird Count reports is presented. The proportion of each month's gull population is shown for 6 square Zones designated by latitude and longitude. The number of birds present per Zone is plotted therein according to Quadrats (=1/4 Zone). USAF bird strikes occurring during 1974-1977 also are mapped for comparison. This preliminary summary of gull distribution and strike data can be used to identify when and where gulls may be presenting a significant hazard to low-flying aircraft. Application of the information duirng flight planning could reduce the number of strikes caused by gulls. Continuing studies will attempt to refine the application of such bird data to predict hazard levels to aircraft. (Author)
