90-101A - Approval Guidance for RNP Procedures with AR

Date Issued
February 23, 2011
Responsible Office


This advisory circular (AC) provides airworthiness and operational approval guidance material for aircraft operators conducting Title 14 of the Code of Federal Regulations (14 CFR) part 97 Area Navigation (RNAV) Required Navigation Performance (RNP) instrument approach procedures (IAP) with Authorization Required (AR), charted as "RNAV (RNP) RWY XX." Hereafter, refer to these procedures as "RNP AR" within this AC. Operational approvals obtained under the guidelines of this AC also apply to existing RNAV (RNP) IAP with special aircraft and aircrew authorization required (SAAAR). As current RNAV (RNP) SAAAR instrument approach charts are revised or amended, they will be updated to reflect AR.

a. Method of Compliance. This AC provides a method of compliance with public RNP AR IAP requirements. In lieu of following this method without deviation, operators may elect to follow an alternative method, provided the alternative method is acceptable to the Federal Aviation Administration (FAA).

b. Language. This AC uses mandatory terms such as "must" only in the sense of ensuring applicability of these particular methods of compliance when using the acceptable means of compliance described herein. This AC does not change, add, or delete regulatory requirements or authorize deviations from regulatory requirements.
