The Century Electronics 409 Oscillograph is a flight data recorder system, widely used in both military and civilian aircraft through the 1960s and 1970s to study aerodynamic performance and stresses. The 14-channel 409 was employed in dozens of different fixed- and rotating-wing aircraft, to record any conceivable performance factor. Such factors include altitude, airspeed, acceleration, roll rate, pitch rate, vertical ground height, vertical load factor, rotor rate, engine torque and available weapon stores. The example pictured here is mounted on a pull-out tray with a Technology Incorporated 072621D30017 bridge control unit, and was used to record structural stresses and other flight characteristics in the Lockheed C-130 Hercules.
