Finding the Steepness of a Ski Slope Using Infinite Flight
You might be a little confused by the title, so here is some background:
A few hours ago, I was looking at different grades of ski slopes for no reason. I also wanted to fly in IF, because I hadn’t done that for a few days. After thinking about both of these ideas, I started synthesizing them to think about how accurate Infinite Flight’s terrain is. To test that, I decided to take my trusty xCub out to a ski resort and find out for myself.
Now for actually how I did it:
First, I took off from Mammoth Yosemite Airport (KMMH) in my xCub and landed on the ridge of Mammoth Mountain. The mountain is pretty easy to find in Infinite Flight, and you can even see the ski runs clearly on the lower parts of the mountain.

After landing on the ridge, I decided to try out my measurement idea on one of the less steep runs on the ridge (still very steep), Cornice Bowl. I found the top of the cornice fairly easily, and got ready to “ski” down. Once I was at the edge, I gave it a little bit of throttle, and gravity did the rest. Soon, my xCub was flying down the side of the mountain at the same angle as the slope. I then switched to pilot view around the lower part of the run, and looked at the screen to find the angle of the nose. I could only look for about 2 seconds, but I estimated an angle of -25 degrees.

Now that I had found my angle, I needed to compare it to the actual steepness of Cornice Bowl on Mammoth Mountain. I found the grade on a website to be -52.8 %, but I needed to convert that to degrees. After popping it into a conversion calculator, I found that the actual angle of Cornice Bowl was -27.83 degrees.
My Estimated Angle using Infinite Flight: -25 Degrees
Actual Angle from IRL Data: -27.83 Degrees
I was very surprised at this number because it meant that Infinite Flight was within 3 degrees from the real steepness of a mountain. This shows us that even though sometimes IF terrain doesn’t seem as advanced as some PC sims, it is very very accurate to the real world.
