My airline (QF) has standard descent speeds - for most fleets it is 280kt. We are told that ATC knows that. I have never witnessed a fellow crew member intentionally descending at a speed other than 280kt unless requested or authorised by ATC, so I don't understand the comment that you never know what speed we are doing.
My understanding was that QF/JQ and DJ all have an agreement with ATC that our descent speed WILL be 280kts?
Are we ALL doing 280kts as per this agreement or is this all a load of crap?
