Analysis of Aircraft Operating on Contaminated Runway Surfaces

Data for the performance of aircraft operating on contaminated runway surfaces have been analysed extensively, resulting in the production of a number of ESDU methodologies.

The statistical analyses conducted comprise a significantly wider range of data than considered elsewhere.

ESDU 05011 comprises a summary of a mathematical model that can be used to analyse the retarding forces acting on an aircraft tyre that operates on a dry or contaminated runway surface.  ESDU 11004 extends the application of the model to a complete aircraft undercarriage.

More recently, Data Items listed below were issued which demonstrate the practical implementation of these mathematical models.

-          ESDU 10002 describes how to use the mathematical models, considers regulations for contaminated runway operations, and describes the difficulties that operations on such runways pose.

-          ESDU 10003 is an application of the mathematical model from ESDU 05011 to an aircraft tyre that is operating on dry and various contaminated runway surfaces.

-          ESDU 10004 demonstrates how to use the mathematical model to determine the depth of a contaminant covering a runway surface based on measurements made by a ground-test machine that operates on the said runway.  Such information could then be implemented in performance modelling for an aircraft that is about to operate on the runway.

-          ESDU 13002 is an analysis of an aircraft that operates in a braked state on a water-covered runway.  The mathematical model from ESDU 11004 is implemented to determine the decelerating forces acting on the aircraft’s tyres.
