Mechanical Accelerometers / G-Meters

QED is the remaining manufacturer of mechanical cockpit accelerometers designed and tested to meet the demanding requirements of Mil-A-5885, Mil-A25719, Mil-A-27261 and other Mil-A specifications for:

  • Military
  • General Aviation
  • Agricultural
  • Aerobatic

These applications appreciate the quality and steady function of these instruments. Since the 1950s QED has been the manufacturer-of-choice for the Cockpit Accelerometer; the G-force instrument preferred by the pilots of trainers and transport aircraft worldwide. In the original, mechanical version, the QED cockpit accelerometer continues to keep QED as the first choice for pilots of trainer and transport aircraft and for military forces in 28 countries.

Models are available with or without integral lighting. A variety of ranges for every application make the QED instrument the logical choice for measuring vertical acceleration in aircraft. Because the QED cockpit accelerometer is fully mechanical with no electrical power required for operation, dead stick maneuvers can be measured, reset, and measured again.
