Hot-wire and hot-film techniques have also been used on aircraft for airspeed, ... limited to high-frequency fluctuation measurements of air velocity in clear air (e.g. , Lenschow et al., 1978b; Merceret, 1976) and, therefore, will not be discussed further here. ... Probably the simplest in principle is to use vanes which align themselves with the airstream. ... 8 Block diagram of a third-order baro-inertial loop for calculating altitude and vertical airplane velocity from a pressure altimeter and INSanbsp;...
