“Class B”? Is that B for “Bull****”?
Either it’s OK for aircraft to park there or it isn’t. If there’s a risk of jetblast from manoeuvring jet aircraft, there’s a risk from jetblast from manoeuvring jet aircraft. If there’s a MOS requirement, there’s a MOS requirement. How can it be OK for GA aircraft to nonetheless continue to park there “if space is available”?
I’ve seen it all before and heard it all before.
