If you are all so concerned by these minor RT points or inaccuracies I suggest you get a hobby or a stiff drink!!
Who cares - you are making the job harder than it is!! (possibly less enjoyable if you are a check airman and this is the ****e you debrief about)
Saying G'day, Morning, evenings salams whatever is great.
If you are more worried about RT procedures because some pilots say the squark to eliminate certain FIR stations asking it in the next call, get a life a I say. Clogging up the frequency? I think not, your aircraft will not stop flying if you cannot make a call to the appropriate state at a boundary crossing due to congestion!!! They'll get too you eventually.
Is this what flying has come down too? Get a life and enjoy aviation for what we started out to to, fly, and enjoy the craft we work hard at!!
I know the Aussie's and Kiwi's are pedantic about RT but at the end of the day with so many nationalities flying around the middle east does it really matter if squark is stated....
