Abstract : A statistical analysis was performed to determine if there are any differences between externally-lit and integrally-lit (wedge) lighting systems. The light distribution in an existing OH-58 helicopter was compared against two OH-58 helicopters which had their lighting systems modified to an integrally-lit lighting system for another study. The ratio of the standard deviation to mean value was computed for each instrument and the statistical analysis was performed on this ratio.
