Batjac Posted June 25 Report Share Posted June 25 Just wondering, manifold pressure is displayed on my Dynon Skyview engine monitoring screen. With the fixed pitch E-prop, I'm just wondering what I should take away from this indication? Quote Link to comment Share on other sites More sharing options...
Madhatter Posted June 25 Report Share Posted June 25 Nothing. If you have a constant speed or variable pitch prop you need it to set power. The E-PROP is fixed and power output is set by WOT rpm. Maybe if the FAA enacts MOSAIC you can use the E-PROP constant speed prop, but don't bank on it getting done anytime soon. Quote Link to comment Share on other sites More sharing options...
EricB Posted June 27 Report Share Posted June 27 I use mine as kind of a "fuzzy" backup. If I know the normal MP for cruise, descent, etc., then I can set those values if that's my only workable power indicating instrument. As Madhatter notes, with a fixed pitch prop, we all wonder why they include this indication. Quote Link to comment Share on other sites More sharing options...
Roger Lee Posted June 28 Report Share Posted June 28 Map on a naturally aspirated, ground adjustable prop with standarded carbed engine doesn't really help with anything. It will always be 1" - 1.5" less than atmospheric. It's just there because Dynon had it and FD connected it. Quote Link to comment Share on other sites More sharing options...
EricB Posted July 2 Report Share Posted July 2 I've seen mine vary from 10.6 to around 14 (atmospheric). Maybe my carbs are messed up? Quote Link to comment Share on other sites More sharing options...
Anticept Posted July 3 Report Share Posted July 3 That sounds more like your units are in PSIg instead of in.hg., which would be normal. Quote Link to comment Share on other sites More sharing options...
