For Busy B, here are the guidlines for runway arrival usage, when both runways are available (most of the time).
Between 12.30pm and 2000 (local) all aircraft (and this should be reflected on the ATIS) are to land on the North runway (07L or 25R). Outside of the above hours, Freighters, BAC (business aircraft) and GFS (2 Jetstreams) will normally be directed to the South runway (07R & 25L). During the first period above, at the discretion of AMS (Aerodrome Movements South - 118.4), cargo etc may be offered the South runway if it is felt that departures will not be unduly affected/delayed. During the "outside of the above hours", then AMS (or APP for that matter) may enforce individual or groups of freigters etc to land on the North.
The disadvantages for APP is that successive South landers need to be sequenced at least 8 NM in trail, where as this is not the case to the North. Freighters tend to arrive in groups, so the 8 NM issue does raise it's head. The disadvantages for the Tower with South landers is that many aircraft these days have time critical departure slots, and one or more landers on the South can stuff things up. Another disadvantage for the Tower during the "first" period, is the lengthy taxi back to South side parking and the subsequent need to cross 07R/25L.
It is purely a judgement call as to whether or not a decision will be made to alter the normal landing runway for freighter etc aircraft. The call is normally made by AMS and it needs to be done some 10 to 15 minutes ahead of landing time. this means that the AMS needs to have a fairly healthy idea of potential departures (particularly on 25L as the taxi distances are much shorter).
Maybe Dragon69 might like to take some of this onboard. I assume from his posts that he is a KA freighter driver. It might give him good ammo for his next beef.
