This c/s OSPREY 60 Combine I heard on Dublin this morning on 0820 talking to Dublin ATC landing at a Irish Military base. Thepilot sounded English not American and did not mention type of aircraft.

'Osprey' is the ICAO approved call-sign for the PLM Dollar Group - a large UK helicopter operator eg 'Osprey 65' is a regular Twin Squirrel G-NTWK into Liverpool LJLA.

Thanks for info on the overheard callsign Osprey 60 Combine working Dublin. As can be appreciated the ATC workload during the closure and Fire was high and at times extremely comical as only the Irish can be. An example being an FR pilot asked if they had a time when the airport would re open as he had a plane full and was ready to depart, the reply in a nice Irish tone stated " I dont have an exact time yet but we will remain closed until we open" Another Captain requested he de plane passengers for Loo visits as at over an hout on the ground the aircraft ones needed emptying and in any case they only worked when the aircraft was over Flight level 160. ? Irish ATC is always worth a listen into.

Irish ATC is always worth a listen into. Ah-ha, inoperative vacuum generators. You see this on 757/767/777/747 plus Airbus aircraft. On Airbus single aisle aircraft, there is one vacuum generator, and indeed if it is inop, you can't flush the lavs on the ground or below FL160, when differential pressure will cause them to flush. Boeing 757 and widebodies have two systems, one for each side of the aircraft (which allows lavs not serviced by the offending vacuum generator to be used on the ground). Fortunately very rare to have both systems inop. If the vacuum generator was inop, the requirement is that the lavs should have been blocked off until climbing towards FL160 to prevent this situation from happening. If it became inop whilst on the ground, an alert message would pop up in the flight deck.
