  • Aircraft analyzer to determine maximum safe altitude for a given batch of fuel
    Patent number: 5367901
    Abstract: A test procedure to determine the maximum safe altitude that an airplane can be operated at with a given batch of fuel. A pressure vessel is installed on an aircraft to receive a sample of the fuel to be tested. A pressure transducer mounted on the vessel measures the vapor pressure of the sample. The vapor pressure along with the outside air temperature, the carburetor temperature and the fuel temperature are compared with a set of criteria derived from a worse case airplane to yield the maximum safe altitude. The information may be derived manually or automatically by a process control computer.
