A method for evaluating the structural compatibility of an aircraft for use on a runway having a profile with one or more roughnesses in the form of bumps and/or dips, comprising the steps of: generating a first equivalent bump height curve indicative of the elevation and/or depression of the one of more roughnesses of the runway with respect to a reference value; comparing the first equivalent bump height curve with a second equivalent bump height curve indicative of elevation and/or depression limit values of reference roughnesses such that, when the aircraft encounters said reference roughnesses, it remains within the envelope of admissible loads; generating a first power spectral density curve by means of spectral analysis of the profile of the runway; comparing the first power spectral density curve with a second power spectral density curve relating to a profile of a reference runway such that, when the aircraft runs along this reference runway, it remains within the envelope of admissible loads; verifying if the first equivalent bump height curve develops entirely within the first acceptability region and if the first power spectral density curve develops entirely within the second acceptability region; and authorizing or denying the aircraft the use of the runway, on the basis of the result of said step of verifying.
