Force sensing vs. Deflection sidestick… and Neal-Smith FQ criterion

Part of the second year Ghost Project that just took place at ITPS, some simulator surgery was performed in order to assess a force sensing vs. a deflection side stick for a low gain air-to-air task. Study included 4 test pilot students and 2 engineers and had some interesting results.

Beside the LOES and Bandwidth MIL-STD-1797 criteria, this time we introduced the Neal-Smith closed loop criterion which is based in human/pilot modelling. Not as straightforward in its application as the other ones, it has its own strengths especially in assessing a A/C+FCS configuration for various pilot gains/bandwidth frequencies. Towards that direction, the Nichols chart is a vastly useful tool. Cool exercise!
