Abstract: In this paper is presented one of the methods of uncertainty analysis of angle of attack measurement using modular approach. Measurement system is treated as array of serial connected modules, witch are described by the analytical expressions with analysis of   potential sours of errors. Then is analyzed uncertainty of each of sours of errors for each module  and also combined uncertainty  at the output of the each module. Then is analyzed uncertainty of howl system.

Keywords: uncertainty, measurement system, angle of attack.
