The AFMs contain charts for contaminated runway data. We start with dry runway numbers and adjust for wet, slush, compact snow, loose snow wet ice, with or without T/Rs. Our dispatchers have computer programs that consider the same factors.
Landing distance can quickly go from 3500' dry to 12,000' contaminated.
