Test rig mechanical items have to integrate with the hydraulic control system , electronic control system and the aviation control system, this can be done via an “Iron Bird”.

These rigs are used to test aircraft hydraulic systems or components related to controlling the flight surfaces and leading edge systems. For an accurate simulation, the test rigs provide actual aircraft fluid to the components mounted to a structure that closely replicates the actual aircraft. In addition, the system provides a power pack that delivers the hydraulics at the required pressure and flow rate. Data acquisition and control can be provided with these systems allowing the collection of data for product evaluation, and can also provide an automated test profile for unmanned operation and endurance testing.

Once provisional calibration and rig performance is assured, there is a reliance on third party calibration verification, for this we rely on a local calibration laboratory known as TRESCAL (www.trescal.co.uk), who are, ‘our preferred calibration partners’.

A calibration laboratory is a laboratory that performs test, calibration and repair of measuring instruments. The calibration of test equipment is achieved by means of a direct comparison against measurement standards or certified reference materials. These standards are also regularly calibrated themselves, in comparison with another standard of lower uncertainty.

"Comar engineers at UTC site always co-operate well with us, during the calibration of test equipment providing all the necessary information required for validation." - Avtar Singh, TRESCAL
