EFFICIENT AIRSPACE USE
Radar - Doppler Effect
The sketch above illustrates the increased efficiency of airspace use possible with the HIDAN self-contained airborne navigation method.
With present navigation equipment, as shown at the left, a 600-mile-an-hour jet transport will require 100 miles of reserved airspace in order to provide minimum safety.
Precisely navigated aircraft, as in the right of the drawing, can adhere so closely to flight plan that airspace envelopes now required for each can be enormously reduced.
