EGLC allowed aircraft types

[Sarachiel]

Why does Mitsubishi Regional Jet is not allowed in London City while A318/SSJ/E170-195/F120 are allowed? They are usually heavier and require longer runway than MRJ. Is it due addition of MRJ to the game after the list of allowed AC's in EGLC was established?

I guess it's got to do with the real certification of the airplane for EGLC.

That, and the list has been updated recently. It was even shorter 2 years ago(so fortress EGLC was even easier to defend)
