What is the difference between RNAV and VNAV?

In aviation, lateral navigation (LNAV, usually pronounced el-nav) is azimuth navigation, without vertical navigation (VNAV). Area navigation (RNAV) approach plates include LNAV as a non-precision instrument approach (NPA).

What is the difference between an LP and LPV approach?

LP is not a fail-down mode for LPV — LP and LPV are independent. LNAV is not a fail-down mode for LP. LP will not be published with lines of minimums that contain approved vertical guidance (i.e., LNAV/VNAV or LPV). LP is the GPS equivalent of a localizer approach.

What is the difference between LNAV VNAV and LPV?

The difference between LPV and LNAV/VNAV is that although they both have vertical guidance, LPV was intentionally designed to be very similar to an ILS approach with an increasingly sensitive glideslope whereas LNAV/VNAV was not.

What does RNAV GPS mean?

Area Navigation
RNAV, Defined “Area Navigation” (RNAV) allows an aircraft to navigate between two points within the coverage zone of station-referenced navigation systems.

What’s the difference between RNAV and GPS?

Old GPS approaches assume non augmented GPS signal which requires a larger obstacle clearance zone. RNAV approaches support multiple minima, depending on user equipment. LNAV and LNAV/VNAV can be flown by old GPS approach equipment, while LPV/LV requires SBAS equipped receivers.

What is the difference between L VNAV and LPV approach?

Unlike LPV approaches, LNAV/VNAV approaches don’t have increasing angular guidance as you approach the runway. Instead, they’re just like an LNAV only approach, decreasing to 0.3 NM sensitivity when you’re within 2 miles of the final approach fix, all the way to the missed approach point.

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.
