The Port of Hood River is considering whether to install some kind of aviation tracking technology at the Ken Jernstedt Airfield to track takeoffs and landings at the airport.  Port Executive Director Michael McElwee says their Airport Advisory Committee is considering doing a fairly informal tracking project, using available software that would track much of the activity, but not planes with certain types of transponders.  McElwee said another element would involve setting up a small camera and use the images produced to get a sense of what kind of planes are using the airfield and whether they are local or from out of the area, and the times they are using the airport.  He adds by aggregating the data over time, they should get a good idea of the kind of use the airfield is receiving, and the impacts from that.
