Actually the 777 can Autoland up to the max limit of 38kts.
The limitations section mentions the 25 kts "when the
landing weather minima are predicated on autoland operations"
If the weather is ok ( apart from a howling x/w ) then no problems!!
to quote the FCOM 3 limitations section:
Automatic Landing
# Maximum allowable wind speeds when landing weather minima are predicated
on autoland operations:
Headwind 25 knots
Tailwind 15 knots
Crosswind 25 knots
Note:
Crosswind limit applicable to actual LWMO on a non contaminated runway
only. Refer to L.10 ‘Aircraft General’ for other conditions.
This was brought up with Boeing and they confirmed it as written.
The Airbus FCOM 3 Llimitations is worded differently and as such Autolands are always limited to 35/20/10 components.
