Systems and methods for detecting runway conditions are disclosed. A weight on wheel system may determine that an aircraft (100; 510) is on the ground. Wheel speed sensors (322; 324; 326; 328) may measure the speed of the aircraft wheels. Axle reference speeds may be calculated for each landing gear (110; 120; 130) 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 (310) may determine that the runway (50; 520) is contaminated if the on ground threshold was not reached.
