Aerial extraction systems

Aerial extraction systems are those that fully suspend logs in the air throughout the entire extraction process. Skyline cable systems do not meet this criterion in general, because they do not normally suspend logs during the lateral phase of yarding, and the logs may also occasionally drag along the ground at intervals during main yarding, even when full suspension is intended, depending upon the length of the logs and the amount of clearance between the ground and the skyline cable.
