AutoBrake Max not to be used for landing as the manufacturer says don't do it.

DragonAir used it once on an A320 in an emergency landing after problem with electronic flight controls. The aircraft departed the runway after landing, crossed the grass and ended up on the parallel taxiway.

I been in two A330s that landed with AutoBrake Max accidently selected (by the copilot pushing the wrong button to select EGPWS display during descent - this happened after descent chex were completed which included Low or Med Auto Brake selection and cross-check).

These landings were normal for the first three seconds then got very sporty indeed! Lots of very subdued passengers and very red faces upfront.

Absolutely NO problem with brakes, tyres or brake temperatures due to normal landing weights being way below the very high weights and energy required for MTOW certification requirements of the braking system.

When we received our first A340-600 I noted that the AutoBrake system selector was changed from the previous standard pushbutton system.
