" airlines with the best OTP are the ones to be weary of ".....now I've heard everything.
Nautilus, 5nm from in excess of 100nm out, HK is one example.
Bloggsy, yes you hit the nail on the head, all pilots maintaining the same speeds, if you can't maintain 250IAS til 15 miles ( all things, weather/turbulence etc being equal ) then you really shouldn't be in charge or 2IC of an aircraft. (ok, unless your airframe is not capable of that)
In the US there are speed requirements which if not met will mean you go to the back of the queue, as it should be.
Like Hoof said, it's a turd and it can't be polished, changes need to be made.
