1. A method for managing memory access of an avionics control system having at least one control computer, at least one memory unit having a partitioning operating system and at least one application task or task set stored thereon, at least one processor arranged to orchestrate the partitioning operating system and the at least one application task or task set, at least one memory control device arranged to control memory access of the at least one processing device to the at least one memory unit, the method comprising: assigning each of said at least one application task or task set memory access to at least one unique memory region of said at least one memory unit, assigning at least one application data update task memory access to at least one subregion of one or more of the at least one unique memory region, wherein the at least one subregion is arranged to store one or more data parameter of constant data type used to initialize data of the at least one application task or task set during an initialization procedure of said at least one application task or task set, orchestrating said at least one application data update task in order to write at least one data parameter to the one or more of the at least one subregion, and re-configuring the at least one memory control device in order to de-activate memory access of said at least one application data update task so as to protect said at least one subregion and thereby prevent any data parameter of the one or more of the at least one subregion to be overwritten, wherein the step of re-configuring the at least one memory control device is performed prior to completion of the initialization procedure of the at least one application task or task set.
