There is no such thing as a little ice. In airline operations where large numbers of aircraft are dispatched, the process of assuring that each flight will be safe must be a team effort. In smaller commercial and in private operations, the pilot may have to perform all the functions. In all cases, the pilot-in-command is ultimately responsible for ensuring that the aircraft is in a condition for safe flight. If the pilot cannot confirm that the aircraft critical surfaces are free of contamination, take-off must not be attempted.
The reasons for the regulations are straightforward. The degradation in aircraft performance and changes in flight characteristics when frozen contaminants are present are wide-ranging and unpredictable. Contamination makes no distinction between large aircraft, small aircraft or helicopters, the performance penalties and dangers are just as real.
To assist air operators in establishing Surface Contamination Training, Transport Canada has made available this training package concerning the adverse effect of critical surface contamination on aircraft performance. This package consists of three video's and this accompanying Training Manual (TP 10643E) plus sample examination questions. This information is intended to reach all pilots and other personnel who are involved in aircraft operations.
This publication is to be used with reference to the Canadian Aviation Regulations (CARs) Parts VI and VII, Ground Icing Operations Update TP 14052E, the Aeronautical Information Publication (A.I.P.) - Canada, and industry publications.
The videos When in Doubt... for Small Aircraft, Large Aircraft, and Ground Crew, and this package, as well as the copies of the Ground Icing Operations Update TP 14052E may be obtained from the Civil Aviation Communication Center Toll Free: 1-800-305-2059.
