Effect of wet runway on ASDR
I have searched for this but have yet to get my head around the situation.
Compared to a dry ASDR the wet ASDR will be affected by reduced braking action requiring an increase in ASDR. However 2 factors that counteract this are that a wet V1 is typically used so the aircraft has less speed and energy to dissipate. Also, on a wet runway reverse thrust is permitted to be considered for stopping so would total braking action not be better on a wet runway than dry with wheel brakes only?
So does a wet runway make ASDR increase or decrease?
