Abstract: The present intention relates to a method for resetting the static pressure model (mod_Ps3(PCN25R)), called “Ps3 model”, upstream of a combustion chamber in a turbine engine comprising a compressor (3), the Ps3 model being used to arbitrate between two acquisition channels (V10, V20) of the static pressure (Ps3), called “Ps3 pressure”, upstream of the combustion chamber, the two acquisition channels (V10, V20) using two sensors (10, 20), the model expressing the pressure Ps3 as a function at least of the speed (PCN25R), called “PCN25R speed”, of the compressor (3), and comprising the following steps: E1: measuring a value of the pressure Ps3 using one of the two sensors (10, 20); E2: resetting the Ps3 model using the measurement of the value of Ps3.
