Abstract:
1. A vertical rudder control system for an aircraft, comprising: a rudder bar configured for actuation by a pilot of said aircraft; rudder bar position detection unit configured for detecting rudder bar position and generating an electrical control signal corresponding to the rudder bar position; rudder trim compensation generator for generating a rudder trim compensation order setting a nil effort rudder bar position as a rudder bar neutral position, wherein the rudder bar compensation generator generates an auxiliary electrical signal based on the generated rudder trim compensation order, and the nil effort rudder bar position is the rudder bar position at which the rudder bar is controlled with nil muscular pilot effort; flight control calculator configured for calculating, from the auxiliary electrical signal and said electrical control signal, rudder control orders for the vertical rudder, wherein said rudder control orders are calculated, from a sum of the rudder bar position and the rudder trim compensation order, to maintain the nil effort rudder bar position as the neutral position of the rudder bar; and rudder operating unit configured to receive the control orders for the vertical rudder and deflect the vertical rudder by a deflection value based on the control orders.
