The general trend in modern aircraft is toward integrated, all-digital avionics systems. The redundant strapdown inertial measurement unit, which includes a skewed array of four two-degree-of-freedom gyros and accelerometers, is coupled through instrument electronics to two flight computers; this will provide a means to test and evaluate dual fail-operational concepts of inertial measurement units. The inertial sensors and compensation electronics form two separable no-redundant, blocks to enable the failure detection and isolation problem. It is intended to demonstrate by means of laboratory and flight tests that a low-cost dual fail-operational strapdown system of sensors is capable of providing an improved integrated avionics function. This requires substantial visibility via the flight computers to the redundant strapdown inertial measurement unit system operation.
