borgy 0 #1 January 5, 2008 My neptune just got repaired (an they were great about it) and now that I've got it back I noticed below the regualr AGL reading there is an AMSL reading. It seems pretty close to AMSL is this possible?? I didn't think any altimeter could, without setting the QNH read AMSL.

pilotdave 0 #2 January 5, 2008 It's just an approximation based on standard pressure... aka pressure altitude. Gives an approximation of elevation to get an idea of how your canopy performance might be affected. Dave Quote Share this post Link to post Share on other sites
borgy 0 #3 January 7, 2008 so AMSL assumes standard atmospheric pressure 1013?I only trust two people in this world, one of them is me and the other one aint you. Nicolas Cage as Cameron Poe in "Con Air" Quote Share this post Link to post Share on other sites
pilotdave 0 #4 January 7, 2008 Yeah... it's equivalent to setting a plane's altimeter to 1013 (29.92 in the US) while on the ground and seeing what altitude it shows. If the barometric pressure that day is 1013, it'll show the ground elevation. Dave Quote Share this post Link to post Share on other sites
