Response of light aircraft under gust loads

In general, there are two methods widely accepted by the aeronautical authorities. Both of them are implemented in the world leading sets of aeronautical safety requirements. The deterministic method describes the ‘worst case’ atmospheric gust approach. The nature of the gust field is reduced to a form of one dominant discrete gust with closer shape specification. The second approach belongs to the family of statistical methods. The atmosphere is described by the power spectral density function and transforms the problem from the time to a frequency domain. For both methods a set of gust velocities for specific flight conditions has been defined.
