Abstract:

During 1985, a series of flight tests were made at the Federal Aviation Administration FAA Technical Center to develop siting standards for the installation of Automated Weather Observing Systems AWOS at helicopters. The results of this evaluation were documented in the report The Siting, Installation, and Operational Suitability of the Automated Weather Observing System AWOS at Helicopters. A questionnaire OME approved was distributed through the helicopter operatorsmanagers to the users of the New Orleans Downtown Heliport, Indianapolis Downtown Heliport, and Technical Center Heliport. This report presents the analysis of the questionnaires used to determine the operational suitability of AWOS at helicopters. The results of the analysis of the questionnaires indicate that the AWOS equipment is suited for heliport use. A distinction should be made between the prevailing winds at the landing area and winds in the heliport vicinity. This situation can be resolved with the use of a wind sock in conjunction with the anemometer. The wind sock should be placed near the landing pad to provide surface wind information and the anemometer should be placed as close to the nominal landing decision point height as possible in order to provide prevailing wind information above the height of obstacles surrounding the heliport.
