777 Take Off Config

Saw a documentary on a 777-200ER both flights were 11+ hours but on both take offs only flap 5 was used. Interestingly flap 20 was used for landings. Im an Airbus man so not familiar with the Boeing. Do these flap settings appear to be low or is this normal? V1 was 168kts and V2 was 175kts.

T/O 5/15/20 whatever the computer comes up with. If runway is long enough flaps 5 is not unusual even for flights of 14 hours.
Landing 25/30 for normal operations. Flaps 20 only via a non-normal. That is for our operation.

Im with Otterman, F5 is the norm for T/O and 30 for landing (occasionally 25 @ low landing weights on the freighter) F20 is non normal...

In my side we are never allowed to land on 25 normal operations

F25 normal land in my outfit (F30 if required by the FCOM).
F20 for non-normal or again F30 if perf limiting runway.
777 only approved autoland in F20/F30 configs.

F5 normal take off on the 777 but it seems when a tailwind input is given for the perf calculation it almost auto defaults to F15 take-off
777-300 (not many in our outfit): F15 take-off standard (Perf department hasn't done the work on F5 departures but of course possible), sometimes F20 depending if close to the TOPL or not.

Took off at just under 300,000Kg yesterday in the -200ER: still F5 but it was a long runway. Our -300ERs seem to use F15 a lot, maybe something to do with brake energy limits as they appear to be the same packs as the ones on the -200?

For us, F25 & F30 are our routine land flap settings, F20 or less is associated with non-normals...
