Knowing the actual position of the rudder and flap angle is essential for safe manoeuvring and to optimize trim and consumption in navigation. The line includes rudder angle indicators, in the range + -40° also with repeaters, flap angle indicators, in the range -2° +12° and trim indicators with up/down range. The flap/trim sensor is equipped with a leverism to be connected to the piston, generally using a flexible cable (not included). The rudder sensor is equipped with a leverism and a spheric joint plus a second rod to be connected to the rudder shaft.
