Book Description
This report documents the results of a study into the risks associated with degraded performance during rejected and continued take-off from wet and contaminated runways. A comprehensive review of world-wide accident and incident data was undertaken to identify the severity of the problem and the factors involved. Runway condition characteristics, the correlation of runway friction test devices with the friction experienced by aeroplanes, and take-off performance estimation on wet and contaminated runways were reviewed. Performance estimates were examined on the basis of the ratio of contaminated vs dry friction. A method is outlined for classifying runway conditions based upon ICAO SARPS, FAA/NASA trials, and the practices of leading countries and airlines. The frequency of wet and contaminated runways in Canada, the likelihood of critical events on the take-off run, and the take-off weight distribution were determined. These frequency and probability distributions and runway, weather and aircraft performance data were used in a probabilistic analysis of the risk of take-off accidents. A number of counter measures were examined, including the JAR acceptable means of compliance for wet and contaminated runways.

Book Description
Describes activities in the third year of a five-year collaborative test program in which the performance of the National Research Council's Falcon 20 research aircraft was tested on winter contaminated runway surfaces at the North Bay airport, January to March 1998. The objectives of the tests were to: determine the aircraft braking coefficients and aircraft contamination drag on various winter contaminated runway surfaces; obtain additional data to refine the Canadian Runway Friction Index tables for recommended landing distances; and obtain additional data towards the establishment of more accurate models for the effect of contamination on continued takeoff and rejected takeoff performance. Coasting runs with no pilot braking were done to verify the rolling friction coefficient and idle thrust, and to determine the contamination drag. Anti-skid braking runs were done to determine the braking coefficient. Three aircraft configurations were tested in the presence of natural snow accumulation on the runway: continued takeoff, rejected takeoff, and landing. Results are compared with those from previous years and braking performance results are compared with the friction index measured by an electronic recording decelerometer. Recommendations are made regarding both technical content and procedures for next year's test program.
