We were told the opposite - reverse costs way more than brakes due temp cycles and fuel burn. We plebs flying the beast have no idea, it's their train set so we play with it their way.
Folks,
Whether the aircraft has carbon or steel brakes makes a significant difference in costs estimates per landing.
In my experience it favours using reverse with steel brakes, and idle reverse only for carbon brakes.
As many of you will know, carbon brakes do not like being used "gently" ---- the wear rate is much higher cold than at "normal" working temperature, the reverse of steel brakes
Tootle pip!!
