Well, what is "flight critical"? The laws of physics don't change.
Pattern entries are different (at least in Canada), is this flight critical?

Differences (for example) in runway markings and cloud clearances from
country to country are not critical to the successful conclusion of the
flight.

Differences in airspace restrictions and fee structures *are* critical
to my not being arrested, or worse. They are therefore flight
critical, and I want to know what they are at this stage.
