All,
The only performance degradations for takeoff calculations that I can recall dealing with contaminated runway operations on FAR part 25 aircraft are the various clutter charts (U.S). However, landing data reflects wet/dry with (variable) recommendations (non-regulatory) for MU and/or runway condition reports. A high speed abort on takeoff is (1) at higher weight and therefore (2) higher speed than landing for a given trip, however there is no regulatory requirement to have runway friction information incorporated in takeoff computations to guarantee the safety of a high speed reject.
I do not believe that this is an oversight or coincidence. To quantify this data and apply it in a regulatory fashion would shut down most takeoffs on a contaminated runway.
