Can I use LNAV VNAV?

Aircraft with standard GPS receivers (or WAAS) can fly to the LNAV MDA. Aircraft with GPS and approach-certified Baro-VNAV can fly to LNAV/VNAV decision altitude (DA).

Is LNAV VNAV DA or MDA?

An LNAV approach is flown to a Minimum Descent Altitude, MDA, while an LNAV/VNAV approach is flown to a Decision Altitude, DA. If WAAS becomes unavailable, a GPS or WAAS equipped aircraft can revert to the LNAV MDA using GPS only.

What is the difference between LP and LPV approach?

You probably learned that LPV means “localizer performance with vertical guidance.” Logically, then, LP simply means “localizer performance.” The important point is the lateral guidance is angular, with needle sensitivity increasing as you get closer to the missed approach point (think triangle).

What is a V MDA?

(V-MDA is essentially “dive and drive” after FAF.) VNAV may be used as an advisory aid on conventional approaches, subject to the AFM and the standard limitation that the flight crew must use the primary barometric altimeter to comply with all altitude restrictions, including all associated step-down fixes.

What is LNAV V?

LNAV. LNAV refers to lateral (2D) guidance for a GNSS non-precision approach. An LNAV GNSS approach will get an IFR pilot on the correct path, but the pilot must ensure that the aircraft is at the correct altitude at each fix. The aircraft must not descend below the minimum descent altitude (MDA) unless visual.

What’s the difference between LP and LNAV?

LPV is the most desired APV approach. It is similar to LNAV/VNAV except it is much more precise (40m lateral limit), enables descent as low as 200-250 feet above the runway and can only be flown with an approved SBAS Avionics receiver.

Is LNAV a GPS?

GPS NPA (LNAV) refers to a Non-Precision Approach (NPA) procedure which uses GPS and/or SBAS for Lateral Navigation (LNAV). On an LNAV approach, the pilot flies the final approach lateral course, but does not receive vertical guidance for a controlled descent to the runway.
