"SQ 221,are you declaring Air Med One?"
Bit like asking Emirates if they require Rwy 34 or are they just requesting it. If you don't give it to them and something happens your ar$e is grass, just give it to em. Common sense really.
They've got a sick pax, they've organised an ambo...... Ahhh better get it on tape that they are med1 before I clear them. Ar$e guarding at it's worst
