This is a new thread so that the new caption would show. The old thread has this content, too.
The article itself has been re-written with about half the content new, or enhanced.
With respect to the XLS, it's new from the ground up and very user friendly now, even giving CAS from TAS at a known Density Altitude and providing Density Altitude from pressure altitude and OAT.
The Model can now measure prop efficiency in the real world - something I have not seen before. It can also show how things change with weight. It can be used to predict fuel consumption at a given TAS & altitude. Last and not least it shows how the average guy can approximate the CAFE Zero Thrust method of testing quite closely without the special device.
