Oceanic & Remote Navigation (RNP) Authorization

Fly oceanic and remote routes that require RNP 10, RNP 4, or RNP 2. We prepare your B036 package and the procedures behind it.

What oceanic RNP is

RNP stands for Required Navigation Performance. It is the accuracy, in nautical miles, your navigation system must hold at least 95% of the time. Over the ocean there is no radar or ground-based navigation, so ATC relies on that accuracy to keep aircraft apart.

RNP 10 supports 50 NM lateral separation. RNP 4 supports 30 NM lateral and longitudinal separation when paired with data link. RNP 2 is used in some newer oceanic and remote route systems.

Do you need an LOA?

If you fly in oceanic or remote continental airspace where an RNP is required, yes.

REQUIRED

LOA B036 — Oceanic RNP

Required for oceanic and remote continental operations using long-range navigation systems with a specified RNP, including the North Atlantic, the Pacific, and New York Oceanic.

Related approvals

  • NAT HLA (B039) for the North Atlantic — see NAT HLA
  • Data Link (A056) — RNP 4 separation depends on CPDLC and ADS-C — see Data Link
  • RVSM (B046) for FL290 to FL410 — see RVSM

Flying your first oceanic trip? Our International Ops Package handles all of these together.

What the FAA looks for

Aircraft capability

AFM or manufacturer documents showing the RNP your navigation system can meet.

Navigation procedures

RNP verification before entry, GNSS availability prediction, waypoint entry, and route verification.

Cross-checks and contingencies

Position checks after each waypoint, SLOP, turn-back and diversion procedures, and loss of navigation.

Trained pilots

Crew knowledge of oceanic navigation, the oceanic checklist, and the reference documents.

What we need from you

  • Aircraft make, model, serial number, and registration
  • AFM pages stating RNP capability and long-range navigation equipment
  • GNSS prediction method you use (or we recommend one)
  • Pilot names and training records
  • Oceanic regions you plan to fly

What we deliver

  • Complete B036 application package
  • International Operations Manual with oceanic navigation procedures
  • Oceanic checklist and Master Document procedures
  • Streamlined-ready: when your aircraft manufacturer and training provider take part in the FAA's Streamlined Part 91 Operational Approval program, we prepare your package for streamlined review
  • FSDO coordination and comment resolution until issuance
  • PDF and secure online copies for your EFB

Where applications get stuck

We see these delays over and over. We check for every one of them before anything goes to the FSDO.

AFM silent on RNP

Inspectors need documents that state the aircraft’s RNP capability, not just the equipment list.

No GNSS prediction

RNP 4 and RNP 2 depend on GNSS. The manual must say how you check availability before flight.

Missing 10-minute check

The position cross-check after waypoint passage must be written down, step by step.

Outdated contingencies

Contingency procedures must follow current ICAO procedures, not older versions.

Reference list gaps

The manual must list the ICAO documents, ACs, and regional guides crews use.

New owner, old letter

LOAs belong to the operator. A sale means a new application.

Oceanic RNP questions

What is the difference between RNP 10 and RNP 4?

RNP 10 means the aircraft stays within 10 NM of its route 95% of the time and supports 50 NM separation. RNP 4 is tighter, requires GNSS, and with data link supports 30 NM separation and better routes.

Do I need B036 for the North Atlantic?

Usually, yes. NAT HLA requires RNP 10 or RNP 4 navigation, and B036 is how that capability is authorized.

My aircraft has dual FMS and GPS. Is that enough?

The equipment is only part of it. You also need written procedures, trained pilots, and the LOA itself.

Can you add an aircraft to my B036?

Yes. We prepare the amendment and update your manual to match.
