If you are not sure , always check , this will save you from alot of trouble , so don't fall in the trap that different countries do it different,it is true at times , but be carefull and double check at unfamiliar areas,always know where you are ,it happened to me more than once that the Radar Had malfunctions, one of them at 1500 feet high speed ,ATC asked for intentions . Never assume ,otherwise you'll be in error.This is what I do beside knowing Rules and regulation, Diffrences of ATC procedures(JEPPESEN)at different countries,Revise Emergency procedures for that country as well.And very thorough planning for every flight .
