Cool video!
A couple of quick questions, if I may...

1. What is the beep/buzz heard right after the "Stand 'em up!" callout? Is this something from the FMC alerting throttle movement or something else?

2. From what I've read (mostly on a.net), the TO/GA switch is frequently mentioned. Is selecting TO/GA not an option at this stage of landing, i.e. is TO/GA disabled after there is weight on the mains? I was just wondering how this would be integrated with the manual throttle movements of "Stand 'em up" and "Push 'em up."

Thanks!

Thanks Patrick,

1. The beeping noise is the takeoff warning horn. If the flaps, stabilizer trim, spoilers or brakes aren't in the 'takeoff position' then the horn sounds. Since the flaps were in a landing configuration, the check airman has to bring them to a takeoff setting after we touch down.

While the flaps are moving, the throttles are advanced, causing the horn to sound. When the flaps are in the correct position, the check airman would say "push 'em up."

2. We weren't certified to use the auto-throttles all the way to touchdown in our 737s. So to use the TO/GA buttons, we would have had to arm the autothrottles after touching down – and unnecessary distraction during that phase of flight.

Good questions!

Kent
