AIM 4-7-5

In order for an operator with RNP 10 or RNP 4 authorization to obtain 50 NM lateral separation in the Gulf of America CTAs/FIRs, and therefore obtain preferred routing available to RNP authorized aircraft, the international flight plan form (FAA 7233-4) must be annotated as follows: Item 10a (Equipment) must include the letter “R.”

Item 18 must include either “PBN/A1” for RNP 10 authorization or “PBN/L1” for RNP 4 authorization.

Indication of RNP 4 authorization implies the aircraft and pilots are also authorized RNP 10.

Chapter 5 , Section 1 , of this manual includes information on all flight plan codes. RNP 10 has the same meaning and application as RNAV 10. They share the same code.
