"C/S vectoring for the ILS R/W 27 information Bravo, fly heading 060 degrees, descend to Altitude 4000 feet QNH 997mb"
Hmmmm....must agree that this is a lot of information in one transmission. Given that any incorrect readback needs to be corrected anyway, wouldn't it be better to reduce the chance of an error and break this example into two transmissions.
For example:
ATC: "Qantas 26, Glenn 2 arrival, Blaka transition, maintain F350"
ACFT: "Qantas 26, Glenn 2 arrival, Blaka transition, maintain F350"
ATC: "Qantas 26, for sequencing, cross Blaka at time 26 at 250 knots"
ACFT: "Qantas 26, Blaka at 26, 250 knots."
Seems that a little more air time taken up with transmissions, but more likely to get the correct readback.
BTW, do you still say millibars in the UK? Hasn't it been hectopascals for some time. And why do you say millibars when giving QNH? Surely it's a lot different to giving it in inches to our recalcitrant american friends who know nothing of the metric system.
