The system of claim 1, further comprising a data acquisition and conversion circuit (4), comprising at least one input connected to said first group of sensors for receiving said actual second data, and an output connected to said comparator (31). 3. The system of claim 1, wherein said rated first data stored in said memory comprise data representing pressure loss first characteristics and static pressure second characteristics of said controllable air mass flow distribution network, and an operational third characteristic of at least one fresh air source (8) for feeding fresh air into said air mass flow distribution network in response to said first, second and third characteristics. 4. The system of claim 3, wherein at least one of said first, second and third characteristics is stored in said memory (2) in the form of one or more characteristic curves or fields of characteristic curves. 5. The system of claim 1, wherein at least one sensor of said first group of sensors is arranged inside of at least one of said air flow conduits and wherein sensors of said second group of sensors are arranged inside and outside of said aircraft fuselage. 6. The system of claim 5, wherein said at least one sensor of said first group of sensors inside said at least one of said air flow conduits is one of a pressure sensor, a temperature sensor and an air flow volume sensor. 7. The system of claim 1, wherein said second group of sensors comprise at least one external air volume sensor positioned for measuring an air mass flow throughput of external air flowing downstream of said aircraft fuselage. 8. The system of claim 1, wherein said at least one controllable air flow control member comprises one of a controllable flow control valve and an r.p.m. controllable fan or blower. 9. The system of claim 1, wherein said corrector (32) comprises a program memory having stored therein a computing algorithm (pc=f(p, T) or pc=f(H)) for correcting a rated performance characteristic of said air mass flow distribution network in response to data from said second group of sensors to provide said parameter corrected data to said first input of said comparator (31), wherein Pcis the corrected cabin pressure, p is the current pressure, T is the temperature and H is the altitude. 10. The system of claim 9, wherein said comparator (31) compares current performance characteristics of said distribution network measured by said sensors of said first group at current actual pressures and current actual temperatures, with performance characteristic data corrected in response to pressure, temperature and altitude parameters measured by said second group of sensors for a ascertaining any deviations of current performance characteristic data from respective corrected performance characteristic data. 11. The system of claim 1, w
