How reliable are G4,G400,G5 that are 10+ years old?
I wonder how reliable are 10+ years old Gulfstreams G4,G400,G5,G500?
Can anybody share some experience and light on that? I understand it all depends on the hours and landings.
Are they prawn to technical difficulties or are they quite solid in their dispatch reliability?
What about the operating costs?
Thx for Info.
