B737-200 Flap extension during flare

[mendoalex]

I have seen a couple of videos of B737-200 landings and there is something I don't understand. As far as I know an aircraft should be landed using a stabilized approach, no change of aircraft configuration below 500' or 1000' AAL. But in this landings the crew made a final flap extension (I think from 30 to 40) just during flare, before touchdown and after closing the throttles.

Is an approved technique?

Please, I would like som help with that

mendoalex, have a read of some of the comments posted under the video. I suspect that one of them has your answer. It is, also, far from a stabilised approach and far from being recommended. :=

Hot and High unstabilized approach. Final flaps selected but speed above the maximum allowable. If this A/C has flap load relief system which is a protection for the flaps, I suspect that is the cause. When the speed reduced in the flare below flap load relief speed, they automatically extended. I guess that's not something that the pilots planned for.

This guy is just a cowboy. Load alleviation system or no, he has to be within flap speed by the point the last bit of flap goes down just based on wing AOA.
My take is that we are seeing his personal technique for braking a rate of descent. Only a couple of seconds between the sound of the flap drive and the spoilers coming up.
Says volumes about that airline's safety culture.:hmm:
