A system for automatically managing engine control modes of a multi-engine aircraft is disclosed. The system (1) can comprise means (5, 7, 8, 9, 10) for automatically switching all the controlling units (2) of the engines of the aircraft to an alternative controlling mode, as soon as one of such controlling units (2) is brought to such an alternative controlling mode.

1. A system for automatically managing controlling modes in engines of a multi-engine aircraft, said system comprising: (A) a plurality of controlling units respectively associated with the engines of the aircraft, each one of said controlling units comprising: (A1) a first engine controlling parame
1. A system for automatically managing controlling modes in engines of a multi-engine aircraft, said system comprising: (A) a plurality of controlling units respectively associated with the engines of the aircraft, each one of said controlling units comprising: (A1) a first engine controlling parameter determiner configured to determine a first engine controlling parameter associated with a main controlling mode,(A2) a second engine controlling parameter determiner configured to determine the second engine controlling parameter associated with an alternative controlling mode,(A3) a controllable switch, wherein the switch is adjustable between said main controlling mode and said alternative controlling mode, wherein one single controlling mode referred to as a common controlling mode is used at a given instant,wherein said main controlling mode is used in normal operation, andwherein said alternative controlling mode is used at least when said first engine controlling parameter cannot be determined, and(A4) a mode information emitter configured to automatically emit mode information indicating the common controlling mode; and(B) a data transmitter, linking the controlling units of the different engines to at least one monitoring unit, wherein said monitoring unit comprises: (B1) a monitor configured to monitor the mode information emitted by said controlling units so as to be able to detect a situation wherein at least one controlling unit is in the alternative controlling mode thereof, and(B2) a control signal emitter configured to automatically emit at least one control signal to each of the controlling units and to automatically control the controllable switch of each of the controlling units so as to switch each of the controlling units to the alternative controlling mode thereof, when the monitor detects the situation wherein at least one controlling unit is in the alternative controlling mode. 2. The system according to claim 1, wherein the first engine controlling parameter determiner is configured to automatically detect returning to a normal controlling mode, after a previous switch of the controlling mode from a main controlling mode to an alternative controlling mode, and wherein the second engine controlling parameter determiner is configured to emit a control signal to switch all the controlling units to the main controlling mode thereof, when the first engine controlling parameter determiner detects returning to the normal controlling mode, after the previous switch of the controlling mode from the main controlling mode to the alternative controlling mode. 3. The system according to claim 1, wherein said monitoring unit comprises: an OR logic gate receiving at the entries thereof, mode information from all the controlling units;a time confirmation means being arranged at the outlet of said OR logic gate; anda toggle being provided at the outlet of said time confirmation means and being able to generate a control signal. 4. The system according to claim 1, comprising an inhibitor configured to prevent any additional switch of the controlling mode, when a predetermined number of controlling mode switches has already been implemented during a flight. 5. An aircraft, comprising a system (1) such as that specified in claim 1. 6. A system for automatically managing controlling modes in engines of a multi-engine aircraft, said system comprising: (A) a plurality of controlling units respectively associated with the engines of the aircraft, each one of said controlling units comprising: (A1) a first engine controlling parameter determiner configured to determine a first engine controlling parameter associated with a main controlling mode,(A2) a second engine controlling parameter determiner configured to determine the second engine controlling parameter associated with an alternative controlling mode,(A3) a controllable switch, wherein the switch is adjustable between said main controlling mode and said alternative controlling mode,(A4) a mode information emitter configured to automatically emit mode information indicating the common controlling mode,wherein one single controlling mode referred to as a common controlling mode is used at a given instant,wherein said main controlling mode is used in normal operation, andwherein said alternative controlling mode is used at least when said first engine controlling parameter cannot be determined,wherein the first engine controlling parameter determiner is configured to automatically detect returning to a normal controlling mode, after a previous switch of the controlling mode from a main controlling mode to an alternative controlling mode,wherein the second engine controlling parameter determiner is configured to emit a control signal to switch all the controlling units to the main controlling mode thereof, when the first engine controlling parameter determiner detects returning to the normal controlling mode, after the previous switch of the controlling mode from the main controlling mode to the alternative controlling mode; and(B) a data transmitter, linking the controlling units of the different engines to at least one monitoring unit, wherein said monitoring unit comprises: (B1) a monitor configured to monitor the mode information emitted by said controlling units so as to be able to detect a situation wherein at least one controlling unit is in the alternative controlling mode thereof, and(B2) a control signal emitter configured to automatically emit at least one control signal to each of the controlling units and to automatically control the controllable switch of each of the controlling units so as to switch each of the controlling units to the alternative controlling mode thereof, when the monitor detects the situation wherein at least one controlling unit is in the alternative controlling mode.
