If it has happened more than once, surely an aircraft cannot be over fuelled so many times (the flight having commenced in May). If indeed the aircraft is incapable of making such a journey, with a Y161 load, plus charter baggage, which is given an average of 15/20K then XL/Kosmar need to rethink charter needs? Or if the aircraft does have the range are Skywings (the aircraft operator) procedures accurate and are fuel calculations accurate etc???
There are numerous scenarios, though most importantly, given recent happenings, is safety. If the aircraft load sheet shows it is overweight, then something must be offloaded. Coincidentally, Air Bee have reportedly left bags behind on NAP-NCL sectors recently.
One question though. OHY operate MD88's NCL-Turkey and manage to carry all pax/baggage. Are these engines an uprated version to those on the VIK/Skywings aircraft?
