ABSTRACT
The NBS had a computing device that was set for wind speed, altitude, ballistic data, and the aircraft’s movements over the ground, generating course corrections, so the bombardier could con trol lateral movements of the aircraft via the auto matic flight control system (“automatic pilot”). With the bomb bay doors open, the bombardier flew the plane, lining up the crosshairs on the NBS and making level corrections by knobs on the sight, one for lateral movement, the other for alti tude. The bombs dropped automatically at the release angle calculated by the sight’s computer. The bombardier then returned control of the air craft to the pilot.
