IMAPCR ’99
of the conditions and test results, the data was a significant large set of results on many
different runway conditions.
67. Regarding the question of whether year-to-year variations and ground temperatures were
factored into the analysis, the answer was that while the information was available on yearly
variations, it was not included in the study.
68. A question was asked about the realism of test conditions as compared to “real life”.
Mr. Martin replied that actual conditions could be less than one half or as little as one
quarter of all test conditions.
69. The use of EWD was raised again in view of hydroplaning on water and
snowplaning/aquaplaning above 120 kt. Mr. Martin replied that a number of factors were at
work.
70. An observation was offered from the floor that tire contact pressure was more important
than the tire pressure.
71. On the question of the type of snow used for testing, Mr. Martin replied that for some of the
“non real-life” test conditions it was machine-worked snow consisting of very small crystals.
Wrap-up for Tuesday, 2 November 1999
72. In closing the day’s session, Mr. Mazur commented that the presentations and queries
pointed to the fact that attention must be paid in three areas:
• Validation of research methodologies and testing
– general consensus indicated that more testing, analysis, and validation of results are
required in the following areas:
• different surface conditions;
• aircraft types;
• special aircraft operations, such as reverse thrust; and
• harmonization of ground vehicle types used in testing.
• Achievement of stated objectives
– He stressed the importance of working together to achieve the objectives of the
JWRFMP in general and the IMAPCR conference in particular.
• Partnerships and collaboration
– Mr. Mazur emphasized the importance of joint partnerships and support from all
stakeholders in providing resources, equipment, and research and analysis facilities to
meet these objectives.
