AD Aerospace, of Preston Brook, Cheshire, U.K., will supply its CabinVu-123 Cockpit Door Monitoring System for new B737 aircraft for Comair Limited, British Airways’ partner in South Africa. AD Aerospace said the system will improve security on the aircraft by providing pilots with an unrestricted view of any activity outside the cockpit door and in the adjacent galleys. With the system, a series of cameras are linked to either one or two monitors and associated controllers.
