Abstract
Abstract An arrangement for electronic recording of outside world and display symbol registration in airborne vehicles provided with head up display. A recording camera is calibrated with close tolerances to the same reference axes as the head up display's display symbology. Control signals of the display symbology and output signals from the camera are processed and combined in an electronic unit for simultaneous recording in a recorder, e.g., a tape recorder.
