This Second Annual Report of work done under Contract DA 28-043 AMC-02412E 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.
