Back in the dim dark past when men where men and ATCs did whet WE told them to do, it was considered a no-no to use speed brakes. Indeed, I remember flying with one Captain who would gladly fly extra track miles to burn off height/speed rather than use the brakes. When asked why? "Because the brakes cause drag, and thatt's inefficient!!!"
In these days of high traffic density, delayed descents and last-minute speed requests, if you are high and fast, you have one choice. Slap up the boards and get the bitch down!!
It is much poorer airmanship not to use every available resource to control the aircrafts profile than to "Hang on in there" and end up with a high, fast approach from which you SHOULD go-around!
Now Amos,
Anyone who doesn't know about A320 ops and therefore asks about A320 ops is a Galah.....You must be a JOY to fly with!!
You might know about A320 ops, ever heard of common courtesy?
