Further to the ‘High Tyre Pressure Test’ (HTPT) overview presented in Issue 4 2010 of International Airport Review, this article presents test analysis, conclusions and recommendations. Detailed information on test background, facilities and test procedures are all contained in the former issue; therefore, for a better understanding of this second article and for an overall view of the HTPT test, the reader should refer to Issue 4 2010 of International Airport Review.

With the increasing air traffic demands, the aviation industry has made continuous strides in the past 50 years. As a result, load per wheel (and consequently internal tyre pressure inflation) have gradually increased since the initial FAA policy, which was based on a DC-8 configuration at 158,757 tons (18.8 tons wheel load and an associated internal tyre pressure inflation, Pnz of 13.2 bar/191 PSI ).These increases were driven by airlines’ demand to develop and design highly efficient aircraft with maximum reliability and optimised performances. As a consequence, aircraft components are lighter, particularly landing gear optimisation, to meet payload-range requirements and reduce noise and/or drag during approach phase.
