What equipment is needed for an RNAV approach?

What equipment is needed for an RNAV approach?

An aircraft must be equipped with the appropriate Wide Area Augmentation System (WAAS) GPS receiver to conduct the RNAV approach. RNAV approaches vary on capabilities. For example: LNAV (lateral navigation); LNAV +V (lateral navigation with advisory glide slope); LNAV/VNAV (lateral/vertical navigation).

Can you do an RNAV approach without GPS?

The term “RNAV” allows pilots to use various means of area navigation, including but not requiring GPS. They enable specific VOR/DME RNAV equipment to create waypoints on the final approach path by virtually “moving” the VOR a specific DME distance along a charted radial.

Is RNAV an instrument approach?

Area navigation (RNAV, usually pronounced as /ˈɑːrnæv/ “ar-nav”) is a method of instrument flight rules (IFR) navigation that allows an aircraft to choose any course within a network of navigation beacons, rather than navigate directly to and from the beacons.

What is the difference between RNAV and RNP?

Area navigation (RNAV) and RNP systems are fundamentally similar. The key difference between them is the requirement for on-board performance monitoring and alerting. RNP also refers to the level of performance required for a specific procedure or a specific block of airspace.

What is the difference between ILS and RNAV?

RNAV is GPS and satellite-based, while ILS is just a landing system and is fully ground-based. ILS is just a landing system and is fully ground-based.

Does RNAV use VOR?

Area navigation (RNAV) equipment includes VOR/DME, LORAN, GPS, and inertial navigation systems (INS). Some aircraft may have equipment that allows input from more than one RNAV source, thereby providing a very accurate and reliable navigation source.

What is VNAV approach?

In aviation, vertical navigation (VNAV, usually pronounced vee-nav) is glidepath information provided during an instrument approach, independently of ground-based navigation aids. The VNAV path is computed using aircraft performance, approach constraints, weather data, and aircraft weight.

Is RNAV the same as GPS?

RNAV (Area Navigation) is not GPS. RNAV is technically a ground-based system. True RNAV units use VORs to compute point-to-point (random) routes. RNAV existed long before GPS.

What is an RNAV approach in aviation?

Standard VOR and NDB approaches are removed at most airports in the US and substituted by RNAV approaches. The RNAV approach uses area navigation (which typically means GPS but any system that helps the aircraft recognize where it is anytime, even away from radio navigation facilities).

What are the different types of RNAV equipment?

Today, the most common type of RNAV equipment is GPS, although many older systems have been used for decades on larger aircraft. In 1970, the usage of RNAV began. Until GPS went into operation, two other RNAV devices achieved popularity.

What is rnarnav and how does it work?

RNAV is a method of navigation that permits aircraft operation on any desired flight path within the coverage of ground- or space-based navigation aids or within the limits of the capability of self-contained aids, or a combination of these.

Do I need Waas equipment for an LNAV approach?

LNAV approaches are non-precision approaches that provide lateral guidance only. They do not require WAAS equipment. The pilot must check RAIM (Receiver Autonomous Integrity Monitoring) prior to the approach when not using WAAS equipment. See AIM 1-1-19, 5-1-16, and AC 90-105.
