PBN
technology allows aircraft to fly precisely-defined flight paths without
relying on ground-based radio-navigation signals. Required Navigation
Performance (RNP) procedures, an advanced form of PBN technology, can be
designed to shorten the distance an aircraft has to fly en-route, and to reduce
fuel burn, exhaust emissions and noise pollution in communities near airports.
Because of RNP's precision and reliability, the technology can help air traffic
controllers reduce flight delays and alleviate air traffic congestion.
