A control system for electronically linked pilot and co-pilot inceptors (103) permits an asymmetric roll axis feel depending on whether an inceptor is moved inboard or outboard. A circuit (401) receives a signal representative of a force applied to the pilot's inceptor resulting from a side-to-side movement and detects if the force applied is in an inward or an outward direction. A gain factor is applied to the received force signal to produce a factored force signal. The gain applied to a signal representative of force applied in an outward direction is greater than the gain factor applied to a signal representative of force applied in an inward direction. A summer (212, 213) sums the factored force signal with a corresponding factored force signal derived from force signals from the co-pilot's inceptor to produce a modified force signal for use in a force feedback control system associated with each inceptor.

CONTROL STICK AND THROTTLE QUANDRANT ARRANGEMENTS FOR AN AIRCRAFT
An aircraft (101) is provided with a single centrally located inceptor (110) for controlling pitch and roll of the aircraft. The inceptor (110) is provided with a double grip (11, 112) so that it may be comfortably operated by either a pilot or a co-pilot. A central location for the inceptor ensures that its motion and position is visible to both pilot and co-pilot. Not only is this a benefit from a safety point of view but also during pilot training. Alternatively, two inceptors (411, 412) are provided in the centre console (406) adjacent to one another for operation respectively by the pilot and co-pilot and may be mechanically linked. Optionally, the aircraft may be provided with outboard throttle quadrants (117, 118) for operation respectively by the co-pilot and pilot. The outboard throttle quadrants may be mechanically linked together.
A control system (400) for an active inceptor (103) for a fly by wire aircraft permits a zero force null point to settle to a non-zero displacement trim position. An internal position state of a second order mass spring damper model is moved in conjunction with force-displacement characteristic coordinates. This results in no second order dynamics being superimposed on the feel of the inceptor (103) when dynamically adjusting the trim position, thereby eliminating the possibility of any unpleasant buzzing been felt by the operator of the inceptor during a trimming operation.
