FOREWORD
The increased utilization of Area Navigation (RNAV) has improved the flexibility and
capability of the National Airspace System (NAS). However, current RNAV applications
do not exploit the full spectrum of aircraft/navigation performance capabilities provided
by the equipment of some operators. Where the use of these advanced capabilities
allow for more efficient routings, a reduction to Decision Altitude (DA) of at least 50 feet,
a decrease in visibility by at least ¼ mile, or lateral/vertical paths that would otherwise be
unavailable, instrument approach procedures (IAP) may be constructed under the
Required Navigation Performance (RNP) Special Aircraft and Aircrew Authorization
Required (SAAAR) criteria contained in this document. This directive is written for the
use of IAP developers. It provides the tools to construct the Obstacle Evaluation Areas
(OEAs) and evaluate the Obstacle Clearance Surfaces (OCSs) associated with an RNP
SAAAR approach procedure. This document does not discuss the rationale or
philosophical basis of the criteria.
