747-400 Wet stopping distance
Would some kind soul with access to a 747-400 perf manual let me know the Accelerate-stop distance differences for a given set of conditions between wet and dry? Is there something odd about the procedure that makes the wet distance more than 20% greater? Does wet not use reversers? The distances in the Sim seemed wrong and wasn't sure if there was something unusual in the Regs that don't apply to the 2-engined jets I usually operate.
Many thanks
