Systems and methods for detecting runway conditions are disclosed. A weight on wheel system may determine that an aircraft is on the ground. Wheel speed sensors may measure the speed of the aircraft wheels. Axle reference speeds may be calculated for each landing gear based on the speed of the aircraft wheels. A weight on wheel time limit may be reached prior to the axle reference speeds reaching an on ground threshold. A brake control unit may determine that the runway is contaminated if the on ground threshold was not reached.
