Yes, but how much salary would he expect for the privilege of taking up what could be used as a passenger seat?
Like Whirls implied, a decent amount that reflects cost of living around base.
I have yet to see the CEO that would want to sit upfront... I guess for the fun of it, ok; but not as a regular passenger seat with a cozy 6 pax corporate interior in the back.
The co-pilot certainly needs to be typed in that machine too, so he is capable of flying that thing down an ILS, peace of cake. For the little extra expense, the bosses insurance has the benefit that somebody will bring the big man/woman back to terra firma if the Captain passes out...
