Plastis Bug
The fuse plugs should not melt earlier than 800 degrees C (1472 degrees F). That being the limit in the maintenance manual
The surface temp of carbon brake discs may reach all manner of temperatures eg 800 DEG C but the overall brake temp is never allowed to reach such temperatures without various other fail safes kicking in.
Eg thermal fuses and over pressure valves relieving the tyre pressure before a critical pressure is reached.
please give a cut n paste from your "manual" to show the limits you describe.
I was in an A300-600 that landed with max once by mistake,( no mention of the autobrake in the immediate reland check list- now changed)
Certainly dramatic made the first turn off, crew faces nearly as red as the discs, we had to wait for a couple of hours before we could change the tyres
As Ivan aromer described a similar incident I had seen, you should take note. I was not scaring anyone just relaying my experiences
Some aircraft have a crap braking systems that rely heavily on ground support equipment to keep them cool for a quick turn around!
All rudeness deleted and was unwarranted. Apologies Bolty
