Hello KRNET
Does anyone know what an acceptable standard for (fixed pitch) rpm loss with
altitude is? For example, I was told, you'll lose 75 rpm for every 1000'
altitude, regardless of mixture setting or climb/cruise prop. I'm wondering
if this is true with VW/Corvair or is it just the Lycoming/Continental
models or is it all engines. In developing an owner's manual, how do you
test/determine density altitude runway length safety factors? Manually
limiting rpm to simulate altitude comes to mind, but that brings the
original question - what to limit it to.
Thanks!
