A simplified approach to kinematic consistency checking applied to Sea King helicopter flight trials data is given. Prompt implementation of the method was possible, pending longer term development of systems identification technique suitable for application in a general way to helicoper data. This has allowed the formation of a trials data bank with reasonable confidence in the kinematic quantities so that validation of the Sea King mathematical model can continue. In the process adopted, measurements are first digitally filtered to remove noise. Alternative values of kinematic quantities are then derived from the smoothed measurements, using numerical differentiation or integration. For quantities obtained by integration, two separate iteration cycles are used, thus enabling kinematic equations to be integrated independently by separation of variables' using the trapezoidal formula.
