A description is presented of the results of an investigation of the guidance and navigation requirements for VTOL spiral descents in the presence of winds. A spiral approach for all-weather operations for VTOL aircraft is discussed along with aspects of spiral approach guidance. Attention is given to the equations of motion, nominal spiral specification, the wind estimator, and the feedback guidance law. The performance of the spiral guidance algorithms is evaluated with the aid of a realistic example which was selected for the Kennedy International Airport in New York City.
