Regarding level passing. We need it to be within 200ft of the one you give us to verify it in DB. The mode C is supposed to be done everywhere. You may notice it here more, because ourselves and UAE run different radar systems and therefor it needs to be reverified on handover. Most other places I know, you usually pass it in the cruise on first contact out of habit and when you are airborne.
ANSA, carefull now regarding the old chaps. You may wake them. Noticed you have one down your way too.
Cheers
