A color-shift correction image is formed in a density D and it is determined whether the color-shift correction image can be detected successfully. The simulation device may contain a plurality of antenna elements positionable on or near a radar or other sensing device. It further includes a second transceiver having an antenna inside the aircraft and connected to a base station controller. The spring arms stamped from the top plate portion and the spring arms stamped from the bottom plate portions define a pair of guide recesses to guide an electronic card into the insulating housing. In one aspect of this embodiment, the card carriage can dispense at least the first card into a card outlet chute when the first card has been sufficiently read by a card reader.
