This paper reports the spectrum analysis result for turbulence and the induced vertical accelerations of aircraft. The flight data obtained in real flight are analyzed in frequency domain. The obtained power spectrum density of turbulence are compared with a well-known continuous gust model, i.e.\ obreakspace {}Dryden model, and it is confirmed that the Dryden model can represent such turbulence with appropriately defined gains. The dominant frequency range of the induced vertical accelerations is confirmed to be almost less than 0.5 Hz.
