This Second Annual Report of work done under Contract DA 28-043 AMC-02412(E) in support of the USAECOM Avionics Laboratory program covers five tasks: (1) Simple modeling and fundamental considerations of the station keeping control loop are presented. (2) In this report, a problem of considerable interest to people involved with improving existing steady-state STOL take-off techniques is discussed theoretically: minimum distance to clear an obstacle of a given fixed height. (3) A System Study of Low Visibility Approach and Landing is a simulation of the control characteristics of helicopters combined with modeled characteristics of the pilot to determine guidance parameters needed for low visibility approaches. (4) An examination of instrumentation requirements to permit control of helicopter and VTOL flight performance. (5) Results of a preliminary survey of the phenomenon of triboelectricity as it applies to the problem of helicopter electrical charging are reported. (Author)
