AIM Text
- 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.

Common Questions
How do I annotate the flight plan for RNP 10 versus RNP 4?
Per this guidance, Item 10a (Equipment) must include the letter “R,” and Item 18 must include “PBN/A1” for RNP 10 authorization or “PBN/L1” for RNP 4 authorization on the FAA 7233-4 form.
Does RNP 4 authorization also cover RNP 10?
Yes. The AIM states that indication of RNP 4 authorization implies the aircraft and pilots are also authorized RNP 10.
Is RNP 10 the same as RNAV 10?
According to this section, RNP 10 has the same meaning and application as RNAV 10, and they share the same code. The annotation enables 50 NM lateral separation and preferred routing in the Gulf of America CTAs/FIRs.
