An apparatus and method of calculating a vehicle's elevation, speed, distance and time to arrive at a predetermined point. The apparatus includes a mechanical spring-driven clock mechanism having a rotating settable pointer passing adjacent a clock face for visually ascertaining time measurement during a specified time interval. The clock face has a prescribed set of indicia formed thereon defining a nomograph which correlates the vehicle's speed and distance to the predetermined point. An outer annular ring movable with respect to the clock face provides indicia showing the vehicle's elevation at specific time points. Tab elements which are slideably moveable on the annular ring provide visual guides to important elevation points. A central pointer on the clock is set at the selected vehicle speed and distance measurements on the nomograph and relates to a proper vehicle elevation mark on the annular ring. At a specific time designation, the clock pointer movement is initiated. The apparatus then provides a continuous display of elevation, speed, distance and time to arrival at the predetermined point.
An aircraft navigational computing apparatus comprising:
A computer for use in aircraft for correlating the distance to be travelled by an aircraft moving at a predetermined speed from a fixed point on an approach to a landing field with the altitude to be maintained by the aircraft during the approach to the field, comprising a clock mechanism having a face, a shaft extending from the clock mechanism through the face thereof and rotatable by said clock mechanism, a pair of dials each having a different diameter and mounted concentrically about said shaft at said face, one of said dials having suitable indicia thereon for indicating the distance to be travelled and the other of said dials having suitable indicia thereon to indicate the altitude to be maintained, said dials being mounted for relative rotation of one to the other, a pointer mounted on said shaft for rotation therewith and movable with respect to at least one of said dials, and one of said dials being movable relative to a reference mark on the other dial to indicate the altitude of the landing field, so that the distance to be travelled and the altitude to be maintained can be correlated one to the other.
