Description:
Soft or rough runway surfaces (grass, sand, snow) require slower and smoother landings. Pilots must use the wings, not the
landing gear, to support the weight of the airplane (by holding backpressure) as long as practicable.
Common Errors:
•
Unstable approach (excessive descent rate or airspeed)
•
Round out too high
•
Poor power management during round out and touch down
•
Hard touchdown
•
Transferring weight to the wheels (letting the nose wheel fall) after touchdown
