Another point.
Why the change to the inbound profile on non precision approaches from the old 300'/nm (5%) to the 5.2% (320'/nm) gradient.
Yes, the new profile might be technically the correct one but it's a f**k sight easier to work out 3 times the distance plus/minus correction in your head than it is to do 3.2 times distance plus/minus correction to check your profile as you fly the approach.
The old 300'/nm certainly made for less worklaod on the approach and there was almost no need to keep referring to the plate to check your profile.
The new system sucks and obviously designed by people who never use the plates they design.
The old system was practical and it worked why change it?
Sorry for the thread drift.
