Southwest says required navigation performance benefits slow to emerge
from Aviation Week
While Southwest Airlines has flown more than 5,800 required navigation performance (RNP) approaches since January, the carrier says RNP is not yet justifying its business case. The carrier began RNP operations with the majority of its fleet on Jan. 11, 2011, and is one of the earliest adopters of RNP in the U.S. Although it has equipped aircraft and trained its pilots, the carrier still has to rely on RNP approaches published by the FAA. The rate of introduction of these approaches has been slower than expected, says David Newton, Southwest’s senior manager for NextGen and airspace.
