Abstract
A piloting assistance system for assisting the piloting of a vehicle, the piloting assistance system comprising at least one display and a plurality of sensors for each measuring a value of a given parameter, the at least one display being configured to display a symbol carrying the value, the plurality of sensors comprising redundant sensors with a redundancy of order three or higher. The piloting assistance system comprises a display controller configured to select, according to stored logic, a selected sensor from the plurality of sensors, the at least one display using the value of the parameter measured with the selected sensor to display the symbol.

A piloting assistance system for assisting the piloting of a vehicle, the piloting assistance system comprising a plurality of displays and at least one set of sensors comprising a plurality of sensors each measuring a value of a given parameter, each display being configured to display a symbol carrying the value, the plurality of sensors comprising redundant sensors with a redundancy of order three or higher,
- wherein the piloting assistance system comprises a display controller configured to select, at least in an automatic operating mode, according to a stored logic, a selected sensor from the plurality of sensors, each display using the value of the parameter measured with the selected sensor to display the symbol;
- and
- wherein the plurality of sensors comprises a number of groups greater than one, each group comprising at least one of the sensors, the groups being ranked according to a ranking order ranging from a highest-ranked group to a lowest-ranked group, the display controller selecting a sensor from the first group deemed to have integrity, starting from the highest-ranked group according to the ranking order.
A method for determining a value that has integrity of a parameter, with a piloting assistance system, the piloting assistance system comprising a plurality of displays and at least one set of sensors having a plurality of sensors each measuring a value of a given parameter, each display being configured to display a symbol carrying the value, the plurality of sensors comprising redundant sensors with a redundancy of order three or higher,
- wherein the method comprises selecting, at least in an automatic operating mode, with a display controller, according to a stored logic, a selected sensor from the plurality of sensors, each display using the value of the parameter measured with the selected sensor to display the symbol;
- and
- wherein the plurality of sensors comprises a number of groups greater than one, each group comprising at least one of the sensors, the groups being ranked according to a ranking order ranging from a highest-ranked group to a lowest-ranked group, the method comprising selecting, with the controller, a sensor from the first group deemed to have integrity, starting from the highest-ranked group according to the ranking order.
