first officer (31, CPL, 1,182 hours total, 937 hours on type)
So how'd that work out....
15nm out the aircraft was cleared to descend to 2000 feet, the captain now urged to slow the aircraft using spoilers as the aircraft was still doing 250 KIAS, the first officer advised he was maintaining 250 KIAS to accelerate the descent.
I'm not defending the captain for the final result, but you don't keep doing 250 at 15nm in cr@p weather trying to dive off a bit of altitude.
