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.

Book Description
Some background information is given together with the scope and objectives of a 5-year, Joint Winter Runway Friction Measurement Program between the National Aeronautics & Space Adminstration (NASA), Transport Canada (TC), and the Federal Aviation Administration (FAA). The primary objective of this effort is to perform instrumental aircraft and ground vehicle tests aimed at identifying a common number that all the different ground vehicle devices would report. This number, denoted the International Runway Friction Index (IRFI), will be related to all types of aircraft stopping performance. The range of test equipment, the test sites, test results and accomplishments, the extent of the substantial friction database compiled, and future test plans will be described. Several related studies have also been implemented including the effects of contaminant type on aircraft impingement drag, and the effectiveness of various runway and aircraft de-icing chemical types, and application rates.
Book Description
The Joint Winter Runway Friction Measurement Program was created in 1996 to undertake a five-year initiative to study winter runway friction measurements. This report reviews the history of the Program and its activities in friction research, field tests of friction measurement methods & aircraft braking performance, and development of the Canadian & International Runway Friction Indexes. The last section outlines future goals and challenges to implementation of a world-wide standard runway friction index.
