Final Report on N704CK over-run

[embpic1]

That's not entirely correct. The default for KA's version of the OPS program for "Dispatch Landing" is WET, which may be overridden under specific circumstances. The default for "Takeoff" and "Operational Landing" is DRY. DRY is always used unless, of course, the actual runway condition is reported or observed to be WET.

Also, the effect of reversers is not factored in performance calculations for the Classic airplanes. Speedbrakes, however, are absolutely essential. You have to get the weight on the wheels to get full brake effectiveness

Correct.

This accident is a good lesson to us all. Do not abort above V1 unless you can no longer keep it on the runway (loss of directional control). When those hands come off the throttles at V1 I always say to myself 'We are going flying'

So if all this is true, why would someone make an intersection T/O in a Whale when T/O data was for full length? I was always told that was a no-no, as in FAA violation if found out about. Did I miss the part in the accident report where it says the F/E recaculated for a B1 departure?

I got the impression that the crew wasn't aware that they weren't using full length. The line drawing overlaid on the runway diagram doesn't indicate much runway that they left behind, and it appears that most of what was behind them was overrun/underrun. As it is, the difference between how far they went off the end and what was behind them at start of roll is pretty small, based on the pictures, anyway. I know - we could "what if" this all day, just like any accident/incident. All I know is that in years past in a previous life, I took off from what I thought was the end of the runway only to find the next day that there was about 500+ feet more available that none of us could see in the dark and on our first departure from that airport. I imagine that this crew has been to this airport at least a few times with their history with the company, so that's probably a lame excuse, but it happens...

The analysis seemed to conclude that the crew did use speedbrakes/spoilers, and I'll guess retracted them after stopping (which is part of our reject procedure, anyway, don't know about Kalitta). Still at a bit of a loss as to why they didn't use reverse.

Thanks for the clarification on the takeoff data, HK.
