e. Runway surface/condition

ACS element text (the applicant demonstrates understanding of)

Effects of: e. Runway surface/condition

Bottom line

Some airplane flight manuals (AFM) provide little or no guidance on how to modify takeoff and landing distances for contaminated runways. A pilot needs to control the airplane in a manner that the wings support the weight of the airplane as long as practical to minimize stresses imposed on the landing gear by a rough surface or to prevent sinking into a soft surface.
