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.
