Running runup?

Dale,

Always. I fly from a turf field....stationary runup is bad for the
prop.

How? If it were dirt, I might understand, but turf?

Being on
grass the speed doesn't become a big issue...no need to hold brakes
during the checks.


I disagree, strongly. Going with 2000 rpm, our Tobago would move like a
rocket on our turf field.

There's dirt under that grass. Even water can erode a prop, imagine
what dirt or small stones can do.

There is nothing - absolutely nothing - half so much worth doing
as simply messing around with airplanes.

Have you tried it? Sure, you'll be moving faster than a "walking pace"
taxi, but not so fast as to be a hazard.

Yes. At 2000 rpm I would accelerating at quite a clip. After a couple
hundred yards I'd be doing in excess of 30 mph.

If I tried to do my runup with no brakes, I'd be airborne before I finished the mag
check.

Good grief, how long does it take you to cycle a prop? G You're only
at that power setting for a few seconds...but by all means do what
you're comfortable with.

Prop, mags and carb heat are done at 1700 rpm in virtually all Cessna's.
The exact rpm isn't important.

The Hartzell prop needs 2000 RPM.

Yes. And I disagree. Definitely hazardous.
