ADVERSE WEATHER OPERATIONS DURING THE CANADIAN ATLANTIC STORMS PROGRAM

For cooperative research programs with the Atmospheric Environment Service of Canada, the NRC Twin Otter Atmospheric Research Aircraft was instrumented to measure the motion and thermal structure of the atmosphere and the microphysics of cloud and precipitation. In 1986 the aircraft was flown in the Canadian Atlantic Storms Program to investigate large east-coast storms that typically account for the bulk of the winter-time precipitation in the Maritime provinces, and cause havoc for airborne and surface transportation. A variety of adverse flight conditions were experienced including heavy snow contributing to limited IFR alternates, airframe icing, wind shear and crosswinds on landing. Examples are presented of these incidents analyzed from both a flight research and meteorological perspective using aircraft recorded data. For this project, additional specially-designed deicing boots were installed on the Twin Otter's vertical tail and the wing and the landing gear struts. The performance of the enhanced aircraft deicing system will be discussed using data from three deicing encounters.
