Take off and landing performance charts.

Does anyone have a TO and land perf chart for RV7A, 0360 fixed pitch?
I want to calculate high density take off performance.

Thanks!

I've looked at a number of owners manuals and have not found anything.

Is there a "rule of thumb" for every 1,000 feet of density altitude equals another 120 feet of take off runway required?

A long, long time ago, I obtained a couple of Denalt Performance Computers. These circular slide rules are used to estimate the take off and climb performance for an airplane with a normally-aspirated engine. There is one for a fixed-pitch prop and one for a constant speed prop.

You set the air temperature and against the pressure altitude scale, read a factor to multiply against sea level performance. For example, 6,000' pressure altitude and 100 F, the take off distance increases 2.9 times and the rate of climb is 24% of sea level's.

At this temperature, the slide rule only goes up to 6,000 feet, unfortunate here in Colorado as we have airports higher than that.

This suggests that you might be able to find something equivalent, perhaps an on-line calculator, that provides similar estimates.

Koch chart.

Maybe this app will meet your needs. The only downside is that it is in meters instead of feet.
