Altitude ceiling engine choices

You guys are giving bad advice. I fly a Glastar with an O-320 E2A in
it. I have flown dozens of hours at density altitudes above 15000 ft.
And that is with the plane loaded to GW.


I agree, I have flown my RV-6 at 15000 ft several times when I had a
O-320 E2D on it and it was still climbing with no problem. I used to fly
across the mtns. in my Tripacer at altitudes of 14,500. John Ammeter
something does not sound right that you could not get your RV-6 above
13,500.

Someone with 150 hp and a cruise prop might not be able to generate a whole
lot of rpm and therefore power at that altitude. It goes back to the
compromises you make with a fixed pitch prop. Also, it depends on how
heavily loaded the RV-6 was. I list my 160 hp, fixed pitch RV-6's gross
weight at 1675 lb, and the climb and altitude performance really suffer with
the last 50 lbs or so.

that sounds like my situation...

Plane is telling you to skip desert!

It might have been the payload.... I know we were at or slightly over
gross... The stick had a very light "feel" to it, like we were close to
the stall..
