At 6am on my way back from some far flung place I am more than happy to comply with SOP and get the speed back.
If CDAs are required then, of course, try and comply. Most of these destinations are day flights or long enough to get some sleep on the a/c.
If I have to fly level and burn a ''little'' extra fuel then so be it.
It's a damn site cheaper than a go-around and my brain may be able to stay in the vicinity of the aircraft, not 5 miles behind.
Anyone who wants to show me how clever he is by not using the speedbrake on the A330 at 6am will not impress me
Happy landings
