An improved method for avoiding mid-air collision in aviation is disclosed. The method relies on a calibration of radio signal intensities I with radio signal encoded position information L. In other words, after a first reception of a radio signal S advantageously comprising remote aircraft position information L, the radio signal intensity I is measured and a correction factor C is derived. During a next encounter of the radio signal S, a second distance estimation d can be derived using the signal intensity I and the correction factor C. Preferably, relative positioning data is acquired together with the correction factor C and a plurality of correction factors for different relative positions is combined in an at least partly continuous correction function.
