They don't care about fuel
NOT a true statement even in the Gulf!
Especially seeing as they want to go for an IPO in 2013 expect to see a lot of other fuel saving and cost cutting procedures.
So TRUE and CDA is one good option of saving fuel and like someone said, the modern toys can plan and execute a perfect CDA on their own, without considering ATC or altitude restrictions!
Having said that, if you aren't stable on an approach (after the commit altitude = usually < 1000ft AGL) we
MUST execute a GA, and ... here we have just lost the opportunity the get the golden ORYX FUEL AWARD at the end of the year. I'm just kidding about the award but you got the message! Unstable app. not follow by a GA is pretty bad picture. This was one of the reasons why TK1951 'landed' short in AMS. Lessons identified.
