Carbon brakes last longer on the E145 by over half if you heat them up. Anotherwords, don't use reverse and if you want to really do what EMB recommends then don't even pop the doors as the $600,000 cost of TR reverse door overhauls comes in to play. The engines are on condition, the TR doors are not.

Using carbon brakes incorrectly will reduce brake life by half. Carbon brakes build a film around them when they're heated which protects the brakes as they're applied. If you use max reverse then lightly apply the brakes then the carbon brakes will develop a chaffing or particle that will be very abrasive on the brakes and wears them out twice as fast plus you just wore out your TR doors to boot. So if you see those things in the amber, calm down. Just don't blast off with them in the amber.

They figured this out from the European operators that didn't have TR installed on their 145s having brakes that lasted twice as long as their American counterparts at XJT and AE that had TRs. Thats when they changed the books to say heat up the brakes.

Flaps are your choice, I used 45 when the runway was a factor and 22 when I wanted a better shot at a greaser but I've seen that thing grease when it shouldn't have and thump when it shouldn't have and just the opposite. Land with power, don't land with power, land 22, don't land 22, land and blah blah blah. Just do something before it hits the ground.
