Oh just to add, these are a few of the lessons I have learned over the years to which others might want to add in so far as AT instructions are concerned:
Line up - no thanks, there is already an aircraft on final that is just about to land
Turn left 30 - no thanks there is a bl**dy great down poor going on in that bit of the air.
You are cleared to the beacon at 4,500 feet - no thanks you just cleared someone else to the beacon at the same height
Remain clear of CAS - 15 minutes later, I am remaining clear of CAS but it would be nice if you would let me know if you have any intention of clearing me through some time this week.
You are in CAS, you were told to remain clear, turn left 30 degrees immediately - actually I know that I am not inside CAS unless both my Garmins are telling me fibs, are you sure you want me to turn 30 left.
I am sure you could add a few more.
