Abstract:

The purpose of the report is to provide climatological information as an aid in making Facilities and Equipment F and E investment decisions. Ceiling and visibility data from 271 airports were examined over periods ranging from 5 to 15 years. The percent of time various categories VFR, IFR, ILS, VOR occurred is shown by month and by hour groups 07-13, 14-21, and 22-06 LST. Although most of the tables are based on 24 weather observations a day, observing and digitizing practices restrict some to 8 or 14 observations.
