So what does Virgin publish to their flight crew as minimum oil quantity for dispatch?

Fed Sec didn't mention about Virgin using the same system because they don't. They have approval to operate up to 48 hours between their daily checks but this is only to cater for an aircraft which may overnight at an unmanned location. The aircraft always have the daily check done when the end of flying concludes at a manned port.


Qantas have also now had approval given by someone to operate up to 48 hours between checks. Rather than use this as a means to allow aircraft to overnight at an unmanned port, they have introduced this for every aircraft even when there are Engineers present to carry out the check. Bare minimums is now the new normal for Qantas even when as in the case with oil checks, the minimums someone has set has obvious flaws.


I'm not sure what Virgin Tech Crews are told are the minimum oil levels to start.

There seems to also be some confusion in what is actually "dispatch"?

The DDG specifies the point of dispatch as up to "the commencement of the take-off roll".

The extract provided by ALEA Fed Sec quotes "dispatch" 11.4L. What is this document from and what is its definition of "dispatch"?

All the FSO's and memos from Flight Ops quote "prior to engine start".

Which is correct? If you had 12L before start, you satisfy the Flight Ops FSO. If after start the quantity drops below 11.4L, you are then below the minimum per the ALAEA document but ok as far as the FSO.

How can something so simple be so complex?

The document is from the Boeing 737NG Aircraft Maintenance Manual (AMM). Dispatch when talking Engineering terms would mean prior to engine start. I don't think there is a definition of this in the manual.
