A selection unit (38) selects one of the electronic control units for controlling the engine of the aircraft. The selection unit comprises a monitoring module (56) that determines a measure of rotation speed of the engine from an output signal of speed sensors (18, 20). The monitoring module compares the speed measure determined by the monitoring module with a rotation speed measure determined by the control units to determine an operating condition of the control units.",
