General Electrodynamics Corp. (GEC), Arlington, TX, is the world’s leading manufacturer of advanced portable aircraft weighing and balancing equipment, heavy-duty portable truck scales, and electronic portable test equipment. Use of the company’s aircraft scales are by aircraft manufacturers, fleet operators, and research and testing labs worldwide.
To ensure that the company’s products produce accurate results, they need calibrating. In the case of GEC’s scales that weigh commercial and military transport aircraft, calibrating involves using a press to apply precise loads from 0 to 100,000 lb to the scales while comparing the scale readings with the known applied force. To meet the company’s specifications, the readings produced by GEC’s scale testing systems must be accurate to at least 0.025% of the applied load when testing a scale with 100,000 lb.
