System for providing estimations of independent, dissimilar flight parameters of an aircraft and related aircraft

The system has multiple measurement probes including an aerial part (24) to provide physical size that is correlated to flight parameters and different from static pressure. The measurement probes and static pressure taps (281-1, 281-2, 282-1, 282-2, 283-1, 283-2) are connected with each other to form three data systems (SA-SC) that are connected with the static pressure taps. The static pressure tap of each data system is separated from the static pressure tap of the other data systems.
