Claim 13:
14. The method according to claim 1, wherein:
a maximum blade angle deviation as a function of the rotational progress is established by evaluating a behavior of the wind power installation, wherein:
in the evaluation an operation of the wind power installation with variable environmental parameters is simulated or observed in a running operation; and
pairs of values of the blade angle deviation and associated rotational progress are recorded; and

the maximum blade angle deviation is determined as a function of the detected pairs of values, wherein
the maximum blade angle deviation is determined such that:
the maximum blade angle deviation has higher values than the blade angle deviation of the pairs of values of the same rotational progress; or
in an illustration of the maximum blade angle deviation and of the pairs of values in a diagram, the pairs of values are below the maximum blade angle deviation.
