Looks like there is only one reply so far, out of much noise being generated at the GL site... so we'll address the first "legit" reply to our NoC paper...
Didn't 911files show that the radii PfT was using in their last video were fudged? Looks like they're still using those same radii in this paper.
ETA: Why, yes, he did...
Actually, no, he didnt.
1. It appears Farmer cherry picked one "radius" for his claim, not "radii". Yet refuses to show exactly which "radius" he feel is "fudged".
2. Based on Farmers final arithmetic for our alleged "fudged" radius, Farmer calculated his alleged G Load based on bank angle which Farmer claims is accurate -
Farmer calculates G load for given bank...
Banking angle = 62 degrees
g-force = 1.9
Its far from accurate...
First, Farmer doesnt specify speed to obtain such a bank angle.
Second, Farmer's arithmetic is wrong regarding G load for a given bank angle.
Every pilot from a student onward knows the rule of thumb that a 60 deg bank is 2.0G. How does Farmer calculate less G load for a higher bank? I'll tell you why, its because Farmer doesnt understand basic vector analysis as outlined in the paper, doesnt understand how to calculate a sag of an arc, nor is he able to determine a proper radii.
Looks like Farmer needs the chart as his "maths" is pathetic.
Or perhaps he will actually learn something from the tech paper regarding vector analysis.
n = 1/cos(62)
n = 2.13 G's
Farmer is more than 10% off with his "maths".

Back on topic, I've got a minor gripe with the NoC Tech Paper Rob:
I prefer the boldface [vector] version, but "G" is usually written in italic lowercase.
a symbol for the average acceleration produced by gravity at the Earth's surface (sea level). The actual acceleration of gravity varies from place to place, depending on latitude, altitude, and local geology. The symbol g is often used informally as a unit of acceleration. By agreement among physicists, the standard acceleration of gravity gn is defined to be exactly 9.806 65 meters per second per second (m/s2), or about 32.174 05 feet per second per second. At latitude p, a conventional value of the acceleration of gravity at sea level is given by the International Gravity Formula,
g(p)=9.7803267714(1+0.00193185138639sin2(p))/√(1-0.0069437999013sin2(p)). The variation, caused by the oblateness of the Earth and the accleration we experience due to the rotation of the Earth, is about half a percent, from 9.780 327 m/s2 at the Equator to 9.833 421 m/s2 at the poles.
The symbol g was used as a unit first in aeronautical and space engineering, where it is important to limit the accelerations experienced by the crew members of aircraft and spaceships: the "g forces," as they are called. This use became familiar through the space programs, and now a variety of accelerations are measured in g's. The names gee and grav is also used for this unit. Note that g is also the symbol for the gram.
