Publication Date: 1 September 2017
Status: active
Page Count: 24
scope:

This document describes a practical system for a user to determine observer-to-aircraft distances. These observer-toaircraft distances can be either closest point of approach (CPA) distances during field measurements or overhead distances during acoustic certification tests. The system uses a digital camera to record an image of the subject aircraft. A method of using commercial software to obtain the distance from such an image is presented. Potential issues which may affect accuracy are discussed.
