From: A-320 Capt
Default WDR after pushback procedure (DAL/NWA)

Has anybody seen the 22-min video for this new procedure?

They characterize it as the best of both procedures (Delta & Northwest). I disagree. I think it's the WORST of both.

The good part of the Northwest procedure was that you could promptly leave the gate, start your engines, and proceed to the runway while the performance data was being collected. Expeditious? - yes. Possible overload for the F/O? - yes. Good and bad.

The Delta procedure, waiting for the WDR at the gate ... Expeditious? - no. Possible overload for the F/O? - no. Bad and good.

Now we've taken the bad part of both and combined them. It will not be any more expeditious because we still cannot taxi without the WDR (unless forced to move). Either sit at the gate and wait for the WDR -or- pushback and hope you get the WDR before you have to taxi. Now we've created the highly expensive possibility of pushing back, starting engines, and waiting for the WDR. In addition, now we have the incredibly awkward and disruptive prospect of trying to negotiate with ground control to STOP the aircraft in order to perform a checklist. Can you imagine having to do that at some of these busy airports?

"O'Hare Ground, Delta 438."
"Go ahead Delta 438."
"We need to stop here for a moment while we perform a checklist."

Yeah, right!

I think we're going to burn more fuel with this new procedure and it will totally negate whatever advantage they thought they were gaining.

For instance, in scenario #1 in the training video, the crew gets the WDR during the pushback. They start the engine. After the engine is started and as the waveoff is received, instead of taxiing (as we have been doing), they sit there longer, load the performance data, and execute the "Performance Checklist" ... all with the engine running.

I timed it. It takes them nearly 2 minutes from the time the Captain gets the waveoff until they call for taxi. 2 minutes with the engine running.

What difference does it make to delay pushback until the numbers are entered -or- delay taxiing until the numbers are entered? They are both delays. One way or the other, you're going to have to wait. But in the latter situation, you're waiting with the engine(s) running.

Also, in the video - in my opinion, the Captain is far too chatty. I hope this is just a technique item. I've been telling my F/O's to use their good judgment on what to load into the computer off the WDR and to put a checkmark on the line they used, for my quick reference. I compare what they've checked to what they've loaded. If it looks good to me, we go right into the checklist without a bunch of extraneous and repetitive chatter.
