So far, no one has proposed an explanation for the +X segments I
mentioned for EWR's Class B. I'm curious to understand the rationale,
if anyone knows.


+XX simply means they want XX to be flyable without transitioning class bravo.
Without this, most pilots would fly 100 lower (even if not required below
3000)which would have you at 400'-700' operating in and out of Linden. TPA at
Linden is 800.
