1. A device for determining a position of a throttle lever in an aircraft, comprising:
- position sensors each connected to a primary flight control computer, and position sensors each connected to an engine control computer, wherein the position sensors are distributed in at least three groups of sensors such that at least one group includes at least two sensors; and
at least one interface computer, including at least one input that receives measurement information items transmitted by the primary flight control computer and engine control computer connected to the position sensors, and at least one output directed to the engine control computer, the at least one interface computer calculating a group position value for each group of sensors from the sensor position values corresponding to each sensor of the group, and calculating a position value of the throttle lever based on the group position values, the at least one interface computer calculating the group position value by comparing differences between the sensor position values to a threshold.
