R555c & others:
It is normal procedure to use idle reverse for arrivals during the curfew.
Also, the wear characteristics of carbon brakes are such that they wear less when using idle reverse. That was one of the arguments for the Flap25/idle reverse policy. . .less brake wear!!
Crew discretion not withstanding, it would be normal to use idle reverse on a wet 34L during the curfew - I mean, it's hardly a limiting runway.
