Indeed 10W is correct. The approach for 30 brings the aircraft very low over Colinton and the Gyle Shopping Centre (low enough to see into the undercarriage bays) and it gives shoppers in the Gyle cafe something to gasp about. 30 is sometimes not operational because aircraft get parked on it (biz jets, visiting airliners etc) but often flight crews request 30 as against the usual 24.
Hope this helps,
