Abstract
This paper aims to demonstrate the effect of air flow indnced vibration (windage) on PES spectrum, with respect to various bandwidths. Windage is the dominant contributor to off-track error. Moreover there is another important effect which stems from high frequency disturbances such as windage, which plays a significant role in increasing off-track error which is known as aliasing.
