Question

Select the true statement regarding the landing minimums for the KJEF RNAV (GPS) Rwy 12 approach.

1) The circle to land minimums increase more than 100 feet when using the Columbia Regional altimeter setting.
2) The LPV decision height is 951 feet.
3) The LNAV/VNAV has higher landing minima than the LNAV only.
4) The decision altitude for the LNAV is 1260 feet.

Answer 1

The question is related to the landing minimums for a specific RNAV (GPS) approach at KJEF.

Step-by-step explanation:

Circle to land minimums refers to the altitude above the airport elevation which provides a prescribed obstacle clearance during circling approach. LPV (Localizer Performance with Vertical guidance) refers to a type of precision approach that uses GPS navigation to provide both lateral and vertical guidance to the pilot.

The 'decision height' is the altitude at which the pilot must decide whether to continue descending for a landing or execute a missed approach if the runway is not in sight. LNAV/VNAV (Lateral Navigation/Vertical Navigation) and LNAV (Lateral Navigation).

The decision altitude (DA) or decision height (DH) is a specified altitude or height in a precision approach or an altitude in a non-precision approach at which the pilot must decide.
