In order to determine conditions of runway friction by measuring and recording forces acting on a braked wheel rolling on a runway, a vertical force and a horizontal force are exerted on the wheel, the horizontal force being provided by braking the wheel. The forces are recorded directly and the friction coefficient and its sense of change are determined on the bases of recorded values and by the fact that the braking force is continuously changed, to find the peak of the friction coefficient/slip-curve. |
