Something doesn't add up. Runway 22 is only used for GA traffic. Either the wrong runway was given in post 1 or they made a visual approach (unlikely)to the wrong runway. Nearest option to 22 would be 27. Too big a difference to confuse 22 for 27, plus I'm sure that they would have made an ILS to 27. Standing by for some more facts.
I'm afraid not. Rwy 22 is the preferred runway for GA aircraft only because it is closer to the GA/Private handling facilities. It is a shade over 2,000m and has a CAT I ILS and appropriate lighting. Rwy 22 is used by larger aircraft (up to A330 I believe, but don't quote me) during strong winds conditions or sometimes on request for training but is generally not used because the approach takes you straight over Amsterdam city centre. For a similar reason, Rwy 06 is hardly ever used for departures, but I have occasionally departed from this runway but I have lost count of the times the very nice people in the tower have let me land on Rwy 24.
