Kirk Nance: 3029. Trinity Airweighs Weight and Balance System. 2000.



For over 50 years the aviation industry has tried to develop a reliable onboard weighing system. The results of these efforts have ranged from the Wheatstone Bridge in 1944 to Barkhausen Noise in 1999. As early as 1967, attempts have been made to use landing gear strut pressure measurements. The strut pressure attempts failed due to inaccuracies caused by aircraft landing gear strut seal friction, which distorts landing gear strut pressure, as it relates to weight supported. The Trinity Airweighs Weight & Balance System (W&BS) incorporates a new, patented technology which efficiently measures and compensates for pressure distortions caused by strut seal friction. The aircraft landing gear strut has evolved through decades of design changes to be one of the most durable components of today?s modern aircraft. What better tool to use in determining aircraft weight than converting the landing gear strut into a load cell, which is designed to take the abuse of the day-to-day rigors of an airline operation.
The Trinity Airweighs W&BS is permanently attached to the aircraft and converts aircraft landing gear struts into onboard weighing scales.
Dispatching with the Trinity Airweighs Weight & Balance System reduces the time required to measure actual aircraft take-off weight and center of gravity to about 6-8 seconds.
