Thanks 212man; I understand the problems and limitations regarding the simulation programs. Not sure just yet but WPB is looking the favourite.
The 139 passed the 30 minute test, and apart from the odd chip CAS message shown no real problems in this area. Single pump loss=, lower pressure but no real worry I am told.
Many thanks outhouse
