The Port of Hood River will hold a public meeting Thursday evening on operations and development of the Ken Jernstedt Airfield.  It’s the second meeting held on this subject, following up on input received at the first meeting in June.  Port Executive Director Michael McElwee says the airport has seen increased usage over the past couple of years, and that has had an impact on some nearby residents.  He notes TechAero, a business operating at the airport, has taken some steps to help reduce noise impacts, and there are other options as well.  A Fly Friendly program to inform pilots flying into the airport about the surrounding area is being instituted.  But he does point out the Port is limited on what it can do because of Federal Aviation Administration regulations.  The meeting will be at 6 p.m. at the Western Antique Aeroplane and Automobile Museum adjacent to the airport.
