I assume in this picture it's still braking and slowing down? Noticed that the gear dorrs aren't up probably due to the hydraulic problems but I'm interested to find out why wasn't he landing with flaps 30? That doesn't look like 30 to me, more like 20, (correct me should I be wrong)

Thanks guys and sorry for the late reply haven't been able to get online.
Just won dering too, if the hydraulics of the gears fail too and it has to be lowered via the alternate system and gravity force is it possbile to retract the gears back? How about the flaps too? Possible to retract?

Funny you should ask....I was just looking at the schematic of the 777 alternate L/G system today. At first glance it looks like it can only extend. The flaps do not have a connection to the alt. L/G system.

From the looks of the picture, I would guess a complete "A"-System hydraulic failure (not sure of the designations on the 777, but for an equivalent on the 727). That would require manual extension of the landing gear and alternate extension of the flaps. There is no provision to manually retract the landing gear AFAIK.

DAMN! This SUCKS! I just had to go to the next higher age bracket in my profile! :-(

I was indeed out in the typhoon, but going on holiday and not working. Spent a few days in SIN and BKK stuffing myself with seafood!
"HYD PRESS SYS C" or "HYD PRESS SYS L+R" , or a combination of C and either L or R systems means we have to land with Flaps 20 and Vref30+20 and lower the gear manually. To have L+R both fail would be a very bad day, so I guess that this Delta flight probably lost the Center system. No other single failures in the QRH result in manual gear extension and landing with less than full normal landing flap.
