Good question. Why indeed?
Not a joke but feel free to laugh at me.
Now if and that’s a big IF what is being referred to is that 100% of Pitch up or down is 90 degrees then what % of 100 is 6.3 degrees?
So IF 90 degrees = 100% 1 degree is 100/90 or 1.111% so 6.3 degrees is 6.3 x1.111 should equal 6.999 % .( pretty darn close to 7 degrees of pitch)
Using this completely illogical theory 11% of 90 degrees of pitch = 9.9 degrees of pitch. ( I even asked Google what 11% of 90 is to confirm.)
However I found this site which purports to reflect truth regarding % of slopes that an 11% slope agrees with the 6.3 degree figure from the test pilot and now my head hurts.
( Convert Percentage slope/gradient/pitch to Ratio or Degrees
11% = 9.1 Ratio or 6.281 Degrees )
