the tolerated exceedence probability from 3 to 8 % reduces theaverage separation distance for LASAT by about 100 m, whereas anonly modest reduction of about 40 m is observed for AODM.
3.2.4. Separation distances using the factor 4
Using a constant factor 4 over all stability conditions and distancesin combination with OSP-derived stability classes (Fig. 2b)results in by far the largest separation distances for both models(Fig. 9). The area in Fig. 9 has been increased to 3 3 km. TowardsSE, maximum separation distances for 3% reach about 1000 m forAODM and 1600 m for LASAT. Towards NW to SW, maximumseparation distances for an exceedence probability of 3% are about450 m for AODM and 750 m for LASAT. If 8% are tolerated, themaximum separation distances are considerably reduced. TowardsSE, they are 450 m for AODM and 700 m for LASAT; towards west,150 m for AODM and 250 m for LASAT are calculated.The statistical comparison between LASAT and AODM separationdistances using the overall factor 4 is shown in Fig. 10. Apartfrom small separation distances below 100 m, LASAT calculateslarger separation distances, both for exceedence probabilities of 3and 8%. For an exceedence probability of 3%, two lines of pairedseparation distances appear (as in Figs. 6 and 8). Up to 450 m, theupper line can be due to separation distances for NE to SE wind.
