Here’s a picture of the GPI MK1B 6B/406. As you can see it has hooks to attach to the Astrograph frame. I think it projects a spot representing the position of the aircraft onto the chart table. The wind speed and direction are dialled-in and the motors and gears keep the dead-reckoning spot on track.
😡 Let’s not beat about the bush here, “passing stuff off in a fraudulent manner” is not a matter of for the individual conscience nor is it an amusing way of teaching a fool a lesson.
