I really dont understand this quite common "idle reverse" policy...
There are many airports in EU where the noise lobby have influence, and the SOP is idle reverse unless you have a safety issue. Someone told them the auto brakes can do the same thing and TR's do not cause less stopping only more noise.
That, plus some airline SOP's/philosophy that brake maintenance is cheaper than engine maintenance, and don't forget fuel burn, is what causes some guys to stop thinking when it is required.
