Regarding the incident, my airline has had crews misread performance data for 01 and 10 at SFO. I assume it’s got to do with the way our brain processes information. You’re much more likely to confuse 01 and 10 than 08 and 18.
Similar situation with 13/31. Even more so since it’s the same bit of pavement, and your mental picture of the airport may actually add to the confusion. “Did ATC say 13L or 31L?”
Always have to look out for that at JFK, for example.
I am sure you're right, it just pushed a few of my buttons. Saying a typical speed is 160kts means somewhere between 155 and 165. Still way too narrow of a gap. Saying 184mph (to me) means somewhere between 183 and and 185 mph, obviously too narrow of an band. We now confirm the physical runway against the FMS at least twice, I am sure there will still be some events where people get it wrong (hope it's not me...).
