Abstract
Abstract A system for scheduling aircraft arrivals from cruise to touchdown, and also for scheduling departures from airport to cruise altitude; wherein space considerations are reserved to the aircraft pilot and wherein time considerations are reserved to the control authority. The aircraft is navigated by the pilot along a Terminal Corridor Route (TCR) in conformance to the requirements of a ground based Traffic Control Computer (TCC). The airborne Aircraft Instrumentation Computer (AIC) includes a programmed computer and an instrument panel display that positions the aircraft relative to an optimum time flexible energy path and responsive to in-flight data which is also telemetered to the TCC for processing. The TCC repeatedly processes all in-range aircraft on a time cycle basis and imposes and regulates time intervals between said aircraft by issuing speed-up and slow-down commands thereto as necessary to qualify said aircraft to proceed, and alerts the control authority and pilot as well of aircraft which do not qualify and/or require corrective procedures. The system identifies all in-range aircraft and sequentially programs the flight paths thereof along the required track and through waypoints; taking into account the kinetic as well as potential energies involved for executing practical and efficient flight to the ends of infallible traffic control and safety, economy, anitpollution and noise abatement.
