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.
Heathrow is the world’s busiest international airport, handling approximately 471,000 air traffic movements annually and employing over 72,000 people, of which a large number are airside workers. The scale and importance of ensuring efficiency among such a vast number of organisations is clear.
