CS 22.481 Tail-down landing
conditions
ED Decision 2003/13/RM
For design of tail skid and affected structure and empennage including balancing weight attachment, the tail skid load in a tail down landing (main landing gear free from ground) must be calculated as follows:
where:
P = tail skid load (N)
m = mass of the sailplane (kg)
g = acceleration of gravity (m/s2)
iy = radius of gyration of the sailplane (m)
L = distance between tail skid and sailplane c.g. (m)
