jjsemperfi Posted June 25, 2014 Report Share Posted June 25, 2014 Hey guys, just wanted to ask your opinions on what single thing defines a difference between a Precision and NP Approach. I'm going with.... Precision has a DA / DH and NP has an MDA. Anyone agree with this? Quote Link to comment Share on other sites More sharing options...
Flying Pig Posted June 25, 2014 Report Share Posted June 25, 2014 Well, for starters precision will have both lateral and vertical guidance ie. an ILS vs a VOR approach Quote Link to comment Share on other sites More sharing options...
aeroscout Posted June 25, 2014 Report Share Posted June 25, 2014 Lateral, vertical and distance guidance to an altitude you dont' have to level off at.The old ILS had a marker system to tell you your distance from dh(da).The newer ILS/DME and even newer GPS WAAS gives continuous distance guidance.

Gomer Pylot Posted June 25, 2014 Report Share Posted June 25, 2014 (edited) A precision approach has glideslope guidance. From FAR 1: Precision approach procedure means a standard instrument approach procedure in which an electronic glide slope is provided, such as ILS and PAR.

d10 Posted June 26, 2014 Report Share Posted June 26, 2014 ^^ that. It's not really an opinion, it's defined. Quote Link to comment Share on other sites More sharing options...
Machinegun21 Posted June 26, 2014 Report Share Posted June 26, 2014 +1 Gomer Pylot, Precision approach has vertical guidance and hence a Decision Altitude, Non-Precision does not have vertical guidance and hence a Minimum Descent Altitude.

HighCountry Posted June 26, 2014 Report Share Posted June 26, 2014 +2 to the definition provided by GP. Emphasis on the electronic glidepath is provided. For example a VNAV approach in which your glidepath is created by your nav system is NOT considered a precision approach even though it is effectively flown the same way.
