Math Pilots in Validation Data Packages Appropriate Use or Potential Abuse?

摘要

This paper examines the use of math pilots or closed-loop controllers in the development and validation of simulator models. It discusses the reasons why a math pilot can be a useful and appropriate tool. Comparisons of simulation data with actual flight test results will be shown to validate the use of closed-loop controllers. Also provided will be a hypothetical example of the misuse of closed-loop controllers which might result in a close match to the tolerance parameters, but mask a deficiency in the simulation model. The paper also discusses the possible need for regulatory standards for the use of math pilots. Additional requirements, in terms of parameters and their tolerances, will be examined and discussed. If the validation tests are intended to provide an objective comparison between flight and simulation results, then the use of closed-loop controllers needs to be recognized and addressed.
