SINGLE GRlD-HEADING FLIGHT PLANNING OVER POLAR REGIONS

Abstract:	Single-heading flight planning is a recent development in navigational technique. It calls for one single heading of the aircraft during its flight from point of departure to destination. If there are no winds along the route then the single heading will be the same as single course. The aircraft will then fly a rhumb-line between point of departure and destination. When there are variable winds, however, it would be necessary to vary the aircraft’s heading in order to keep it on a rhumb-line track. It is proposed, instead, that the navigator fly a single heading. The track of the airplane will then depart from a rhumb line, the extent of this departure depending on the extent of wind variations.
