G'day guys...
I'm interested to 'hear' that CR2 still uses the Boeing term OEW (Operating Empty Weight) in lieu of the common aviation term ZFW (Zero Fuel Weight), which is as 'close is to dammit' the same thing in it's general meaning.
The other day I was on the line to a Boeing fuel systems DE (Design Engineer) and he told me, amongst other things, that, in our specific 737 manuals, there is a note that basically says that, that OEW is, for all intents and purposes, to be taken as the same meaning.
Cheers...FD...
