This facility, developed for the LCA project, provides complete test environment to assess the performance of Air Data Test system, in situ, at the simulated altitude profile. The programmable test and calibration setup simulates flight profile and excites the pneumatic system to generate corresponding Pt, Ps at the input of ADT. Mach No., IAS and T are then computed by ADT for use by the flight control system of LCA aircraft. Individually the ADT sensor can also be calibrated. The facility also provides a means of detecting any leak in the installed pneumatic lines.
