Yes perhaps-but my goodness it could leak air at a prodigious rate.
Hmmm, strange, never had that particular problem on the ones that I flew, although....these were corporate airplanes, not airliners.
Why on earth equip it with pneumatics when the HS 748, concurrent type, was running the systems on hydraulics?
Because...if you have a system leak, it can be repaired, and there is plenty of 'air' available.
