System for providing independent and dissimilar flight parameter estimates of an aircraft and associated aircraft

A system for estimating flight parameters of an aircraft, comprising

• a plurality of static pressure ports;
• a plurality of measuring probes, each measuring probe comprising an aerial portion capable of providing at least one physical quantity correlated to the flight parameters and different from the static pressure, an electronic device configured to estimate the flight parameters from the physical quantities, and at least one static pressure measurement;
• wherein:
• a first measuring probe and a second measuring probe have identical aerial portions and identical electronic devices;
• a third measuring probe has an aerial portion and an electronic device that are different from those of the first measuring probe and the second measuring probe;
• the electronic devices of the first measuring probe, the second measuring probe and the third measuring probe, and the static pressure ports are connected so as to form a first data system, a second data system and a third data system respectively associated with at least one static pressure port and each providing a respective estimate of the same flight parameters,
• the or each static pressure port of each of the first data system, the second data system and the third data system is different from the or each static pressure port of the others among the first data system, the second data system and the third data system.
