Strange JAL 747 Video Of Takeoff In Snow

Came across this video of a JAL 743 at Sapporo the other day and I'm curious as to why the flight controls check and lowering of the flaps basically occurred in the final moments before takeoff. Just a case of the crew being rather late with pre-departure checklists or is this some kind of winter SOP?

I'm not sure, but I would assume that lowering the flaps late would be to prevent FOD (snow and ice, presumably) from being thrown up into the flap mechanisms.

Haven't watched the video as I'm at work.

Standard winter OPS. Prevents accumulation of snow and ice on the flap drive system.

There are no dumb questions. Only dumb posters.

I mean, eh...

Please excuse me for "way-laying" this thread a bit ... is that a 743 or a 744D? The notes on the video say both ...

How can people like me (i.e., very much amateur spotters) tell the difference between the two?



I'm tired of the A vs. B sniping. Neither make planes that shed wings randomly!

The wing-body fairing on the -400 is bigger, especially the front end. This one looks like a -400 but I could be wrong.

It's a Boeing 747-346 JA8177.

I'm glad I covered my arse by saying I could be wrong. Big grin

The PW engines are a dead giveaway as well. The 744 and 744Ds operated by JAL are GE.
