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.
