It used to be 35/40/45, they then changed it to a blanket <40% in ramp areas. Personally, I'm not going to go over that due to being able to defend my position. You hurt someone the first thing the chief and legal is going to ask is how did you clear the area behind the jet and how can you see behind it? There is no defense IMO.
Have you ever been jet blasted on the ramp? I was blown 50 feet into a blast fence, my glasses and vest blown off, my eyes in pain from the heat, due to a 320 SE taxing out of the ramp..
Thanks for the reference.
Not a hard limit, just requires coordination with ramp/ground crew before disconnect to verify area behind is clear before going above 40%.
I won't fault you though for treating it yourself as a hard limit as not wanting to trust ground crew or a person with a camera to say what is clear to go above 40%.
