Analysis of Distributions of Visual Meteorological Conditions (VMC) heliport Data

Abstract

The FAA Technical Center's Visual Meteorological Conditions (VMC) project was designed to provide data for the validation of the Heliport Design Advisory Circular (AC 150/5390-2) visual approach/departure surface criteria. Procedures for the analysis of data collected during this project were specified by the Design and Operations Criteria Division, AAS-100. These procedures are based on an assumption of the Gaussian, or Normal, distribution. During the data reduction and analysis phase of the VMC project, questions were raised as to validity of the assumption of the Normal distribution for the characterization of VMC data. This report documents an effort undertaken to look at the VMC data for the purpose of drawing conclusions about the proper distributional assumption. Several different procedures were used to test the original assumption. This report provides information on the tests used in this effort and on several alternate distributions, i.e., the Beta and Gamma distributions. (jhd)
