Characterization of Derived Angle of Attack and Flight Path Algorithms

The technical objective of the proposed effort is to exploit derived angle-of-attack (AOA) and flightpath angles (gamma) from low cost Attitude Heading Reference System (AHRS) COTS systems found in general aviation (GA) aircraft. The feasibility of derived AOA will be evaluated for use cases of displays, envelope protection, and fly-by-wire flight control systems. It is expected that the results of this work will be a) recommended minimum performance standards for the algorithm and AHRS device, and b) the criteria for each use case when using AHRS that can be codified into a standard or a circular.
