NWA Airbus / DC9 collision tapes released

[Spectre]

What was the backup of last resort on the thing..
Use to fly it.. but can't remember?

Accumulator or an air bottle for the brakes?

I don't remember the DC-9 very well, but if no hyraulics and no brakes, could he have tried reverse thrust on remaining engine? How about the parking brake? He probably didn't have that kind of time.

Reversers are actuated by hydraulics.

The parking brake holds the pressure that you apply to the brakes through the normal method.

Steering? Hydraulics, too.

You need one hydraulic system operating to taxi.

So, everything was copacetic until they shut down the engine with the operable hydraulic pump?

What should the crew (other than keeping the engine running) done differently?

 

[LarryinTN]

That's it. Keep the engine running with the working hydraulic system.
