Challenger babysitter?
Could be a babysitting job... keeping a close eye on an owner/pilot all the while keeping those NASA reports ready to go.
The posted salary is definitely low for any international Challenger Chief Pilot, low for an international Captain, and close to average for an FO.
The required mins are ridiculously low for an international CP position which raises questions as to the validity of the add. The owner probably just doesn't want to pay top dollar for a true CL601 management pilot.
It appears that the owner is offsetting the cost of the aircraft debt service and operating expenses by chartering it. Logical extrapolation from the add requires one to ask the question... can he really afford this aircraft?
Never believe everything you read in an employment add like this. From my experiences, these positions don't last long at all. I'd be very cautious on this one. Yes, yes, any job is good right now.
Good luck,
