A Means of Specifying a Standard Reference Wet Surface for Military Aircraft,

Abstract

Aircraft specifications which quote stop distances under dry conditions can be misleading since it is the wet case which gives the longer stop distance and may define the length of an operational runway. Trials have shown however, that the wet stop distance can be between 10% and over 100% longer than the dry distance depending on factors such as water depth and surface type. To try and overcome this problem, this paper studies the BCAR method of aircraft certification under wet conditions and the correction of stop distances to a 'standard' using a friction trailer. It concludes there is merit in this well tried method but the 'standard' is unsuitable for military aircraft and the friction trailer should be of the type in service with the RAF. In addition the 'standard' should be related to accident investigation procedures and NATO standards. (Author)
