G L Lindberg, G R Edwards: 1508. The ‘Hael’ System; State of the Art Platform Weighing Equipment. 1983.



Aircraft weiqhinq has traditionally been accomplished using an electronic strain gauge load cell,
fitted into a socket mounted on a jacking post. The load cell is configured to match a ball
attached to the jack point of the aircraft. These jack points are usually on either side of the
aircraft, attached to the wing, and on the nose. The only alternative has been to use platform
scales which have proven to be either inconsistent or too expensive. Now a new method using
Hydraulic Actuated Electronic Load (HAEL) cells; and a high strength platform promises to give the
necessary accuracy at the cost-effectiveness of a hydraulic system.
