A synchro device used to drive a compass dial as the simulated flight progresses comprises a receiver 10 associated with the simulator heading shaft and a transmitter 11 connected to the compass dial and driven from a shaft 17 by a servo system 12 comprising motor 13, amplifier 14 and input resistances 15 and 16. The shaft 17 drives also a wiper 18 of a potentiometer 19 having a resistance winding 20, the wiper 18 being connected to resistance 16. The resistance 15 is connected by lead 38 to a wiper 35 mechanically connected to the indicating member of a main plotting board, not shown. Wiper 35 is in contact with the surface of a board 25 which comprises a series of metallic segments 26, 27 and 28 insulated from each other by insulating strips 29 and 30 and so shaped that they represent geographical areas in which the magnetic deviation is uniform, the difference between the various areas being obtained by connecting the segments to a voltage divider 32. As the simulated flight progresses and wiper 35 traverses board 25 it picks off a scaled voltage which drives motor 13 to move transmitter 11, and thereby moves the compass dial an amount in accordance with the magnetic deviation, so that the compass reading shows the heading of the simulated aircraft as modified by the magnetic deviation. Simultaneously, shaft 17 drives wiper 18 which picks off a voltage to balance the input from wiper 35 whereupon motor 13 stops and the magnetic deviation is held.
