In 2019, a leading European airline faced challenges maintaining their aging Honeywell/Sperry ADT-222A units and sought modern replacements for testing avionics instruments across their fleet. Laversab’s Model 6580 ADTS, a rack-mounted unit with built-in pressure and vacuum pumps, met the airline’s specifications, offering portability, ISO 17025 calibration, and high accuracy for testing altimeters, airspeed indicators, and more. After a successful demonstration and evaluation, the airline purchased two units. Laversab provided free training for 13 technicians and engineers, ensuring seamless integration into their operations. The airline reported successful use of the equipment, highlighting Laversab’s reliability, competitive pricing, and exceptional customer support as key factors in their decision.
