Abstract:

ESDU 11004 evaluates the effects that a layer of contaminant that covers a runway surface, such as water, slush, loose snow, compressed snow or ice, has on the decelerating forces for a set of undercarriage wheels distributed in an array of line-astern and line-abreast arrangements. The model is empirical in nature and based on limited experimental evidence, but adequately describes the data from which it is derived. The Item is a companion to ESDU 10015 which provides a full model for the performance of a single aircraft tyre rolling or braking on dry and precipitate contaminated runways, and ESDU 05011, a summary document of ESDU 10015.
