Speedbrake,
Dubai certainly isn't the land of milk and honey for ATCs, and this is first-hand info! Low morale caused by new 'state of the art' equipment that doesn't live up to its sales pitch, a management that does not really care as long as the company's contract stays intact, an airport that changes virtually daily due to construction, and Emirates flying staff continually getting performance bonuses while ATC, without whom these bonuses would often not be acheived, don't even get an Emirates rebate that is cheaper than an 'across the counter' airfare by way of thanks. (For those of you that don't know - Emirates Airlines and Dubai Airport are basically one in the same.)
Add the above to the 'summer surprise' (45 degrees!!) and the road rage getting to work; you should count yourself lucky to get away with a bit of 'attitude' for asking a dumb-assed question about speed control when it is published!
Glum Weeper,
One would hope you know the Dubai controllers very well - aren't you one!!!!
