ABSTRACT:
An improved tactile control component for aircraft in which a tactile slide is positively driven through a box rack and pinion system from two oppositely disposed d.c. servo-motor assemblies. These assemblies include a relatively high RPM motor associated with a high gear reduction to achieve a positive and compelling tactile sensation at the hand of the pilot. Signals to the device are derived from the computer component of a flight director system or the like. To assure pilot tactile perception of the commands asserted through the apparatus, an emphasis is electronically inserted into command signals to accelerate the initial movement of the tactile slide at the inception of any given flight command. Through the relative positioning of the box racks in a mutually orthogonal disposition, the movement of the tactile slide may be along resultant vectors providing omnidirectional information particularly useful in controlling such components as the cyclic on rotary wing aircraft.
