bsieker Re Autobrake MAX: (#340)
“ this setting provides maximum possible braking, limited only by anti-skid. If you have to do a landing with such a short landing distance available that it would require autobrake MAX, you would not land there. It would almost certainly severely overheat and damage the brakes and tyres.
Max braking is not the potential disaster that you indicate.
Apart from a max or near max brake-energy RTO, severe brake or tyre damage is unlikely. The use of max braking during normal landings is an allowable option and one which should be encouraged if the runway conditions turn out to be less than anticipated. On wet, very wet, or contaminated runways, max braking will not produce a harsh deceleration (often quoted as another reason not to use max as it ‘upsets’ the cabin).

IMHO there is a danger in making such poorly qualified statements, it enables the information to be stored in memory and consciously or unconsciously used to bias decision making in future events.

Are you implying that the auto brake MAX landing distance would not provide an adequate safety margin (1.67/1.92) for the landing?

Do you have an SOP for braking when landing on a contaminated runway – JAR OPS rules?
