CEILING-VISIBILITY CLIMATOLOGICAL STUDY AND SYSTEMS ENHANCEMENT FACTORS

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.
