characteristics are closest to the aircraft being considered as a potential missile. The

scaling method is outlined below.

Compute the scaling factor with which the ordinate (force) of the force

time-history curve of the selected Reference 2 aircraft shall be multiplied.

where:

V1, w1, P1

impact velocity, maximum weight per unit length,

and maximum fuselage crushing strength of the

aircraft being considered as a potential missile;

impact velocity, maximum weight per unit length,

and maximum fuselage crushing strength of the

selected Reference 2 aircraft.

Adjust the abscissa (time) of the above scaled force time-history curve such that,
