Route is blocked by weather and request to deviate denied by Chinese ATC:
Reality Check: We can’t under any circumstance intentionally put the aircraft and pax at risk;
Peril/risk lies in the CB , but it also lies in
a trigger happy PLA grunt with his finger on the trigger of a SAM and possibly unaware that the blip on his radar screen is a civil aircraft and not a part of his exercise.
If fuel permits:
Request hold until weather clears
If weather doesn’t clear or not likely to, or hold denied: advise Chinese controller of your intent as follows:
Contacting Ops with situation: Options:
a) return to point of departure
b) divert to a suitable ERA
If fuel does not permit any of the above then you are truly an emergency and justified in declaring your Mayday, sqawking7700, and deviating accordingly. Pucker a bit when you enter the uncleared airspace.
