What is basic RNAV?
Basic Area Navigation (B-RNAV) was the forerunner of the RNAV implementation in European Civil Aviation Conference (ECAC). Since 2008, B-RNAV in Europe and RNP 5 in the Middle East were supported in continental en-route airspace by RNAV applications. In the United States, RNAV 2 supports en-route continental airspace.
Is GNSS always required to meet RNAV specification?
Unless the RNAV route, DP, or STAR specifically requires GPS or GNSS equipage, aircraft on the RNAV route, DP, or STAR must be within ATC radar surveillance and communication.
What is the difference between an RNP and GPS approach?
An FMS or GPS navigator are both RNAV capable systems. An RNAV procedure is one that requires you to have an RNAV system in order to fly it. RNP, or Required Navigation Performance adds specific performance standards onto RNAV systems.
Who can fly an RNP approach?
RNP APCH is essentially equivalent to RNAV (GPS). If you fly with an IFR-approved GPS, your aircraft meets the requirements to fly basic RNP APCH procedures as described in the AC. But you can’t fly RNP AR procedures unless you also meet the requirements of AC 90-101A.
What is Basic RNP 1?
1. General. Basic RNP 1 is based on GNSS positioning. The navigation specification is intended to support arrival and departure procedures without the dependence on a DME/DME infrastructure.
What are the concepts behind GNSS receivers?
These sections focus on the concepts behind GNSS receivers. GNSS receivers determine the user position, velocity, and precise time (PVT) by processing the signals broadcasted by satellites.
What is the difference between RNAV 1 and Basic-RNP 1?
Differences Between RNAV 1 and Basic-RNP 1 Differences Between RNAV 1 and Basic-RNP 1 • RNAV 1 – Primarily intended for use where radar surveillance is applied • For Instrument Departures, radar coverage expected prior to first RNAV course change – Accommodates a larger fleet of aircraft
Is there an automatic mode switch on the RNP receiver?
There is normally no automatic mode switching (as in the case of a stand-alone receiver), although the default RNP may vary with the phase of flight. For this type of operation it is necessary for the flight crew to select either RNP 1 or accept a lesser default value before commencement of a Basic RNP 1 SID or STAR. 6. Integrity availability
