A US Army H-34 pilot got caught in a fog bank (low clouds) in a canyon. He brought his helicopter to a hover indicated by zero airspeed and zero rate of climb. The characteristics of this helicopter in a hover are to hang tail down by three degrees and seven degrees to the left. His flight instruments indicated that he was in a climb and banking to the left. His air speed indicated zero and his rate of climb indicated zero rate of climb. He had lost all spatial orientation and eventually crashed killing himself, his co pilot and his crewman. Would you have done it differently?
The instruments indicate fuselage attitude.
