Aerospace Instrument-Making Annotation << Back The control of value barometric altimeter based on optimum distinction of hypotheses D.M. Dryagin, A.V. Legkov The adaptive algorithm of the value correctness check of barometric height is offered at use of systems QFE and QNH. The algorithm is based on model of hypotheses recognition about distribution of the difference between orthometric and barometric height. The rule of the decision is optimum by Neumann – Pirson criterion.
