I suppose having 3 flight crews would work, two for the GV and 1 for the 757. It would take 2 crews for the GV to solve the on-call duty issue, and with the 757 flights not being that frequent and mostly planned in advance, a fair amount of scheduled time off could be relied upon for that crew.
JJflyer mentioned his boredom at flying just 120 hours per year, which I understand. The 757 crew might fly twice that many hours per year, but that's all. The GV on the other hand would fly around 600 hours per year, but that flight time would have to be divided between the two crews.
So that leaves about 300 hours per year for each GV crew member and 200-250 hours per year for the 757 crew members. All three crews could enjoy scheduled time off, knowing that when they're off duty, they're off duty. Do you think this would be enough flight hours for each crew member to keep his or her skills up? It seems to me it would be.
Would this work?
