The future of flight path planning is Required Navigation Performance (RNP). GE Aviation is now implementing RNP with airline carriers around the world.

This diagram shows the difference between conventional navigation approach paths and the new Optimized RNP path. Optimized RNP uses on-board navigation that allows planes to follow a more precise track than methods that rely on ground-based beacons or radar. This means a significantly reduced fuel burn, shorter flights, and lowered noise from landing aircraft.
