    • An electronic apparatus is provided that can include a first downloader downloading a replacement control program from an external host computer by way of a first communicator under the control of a first communication program, in a case where a first inspector judges a control program is not normal and a second inspector judges the first communication program is normal. The apparatus can also include a second downloader downloading a replacement first communication program from an external maintenance computer by way of a second communicator under the control of a second communication program, in a case where a second inspector judges the first communication program is not normal, so that a first communication program stored in a rewritable flash ROM is rewritten with the replacement first communication program downloaded by the second downloader.

    • An arithmetic processing method and system in a wide velocity range flight velocity vector measurement system using a square truncated pyramid-shape five-hole Pitot probe. Approximation equations that determine attack angle &agr; and sideslip angle &bgr; in the form of third-order equations concerning attack angle pressure coefficient C&agr; and sideslip angle pressure coefficient C&bgr;, which are known numbers, are expressed in the form of a polynomial equation concerning Mach number M, where the coefficients are obtained from a lookup table. Coefficient calculations in the polynomial equation, and attack angle a and sideslip angle &bgr;, calculations may be performed as simple calculations by specifying and applying known numbers into the approximation equation without solving third-order equations, with calibration coefficients that form the basis of coefficient calculation with the polynomial equation first being stored in memory in advance as a table for each wide velocity range on the basis of wind tunnel testing. A Mach number may be calculated instantly from a lookup table by specifying Mach pressure coefficient CM and angle to airflow pressure coefficient C&ggr;. Wide velocity range flight velocity vector measurement with a high update rate which is capable of real time response in flight control as demanded by aircraft is obtained.
