I hope we have the same success in getting commonsense to prevail.
With the elt issue CASA mandated all the new units must be hard installed in he aircraft. Cost would be about 5k an aircraft
Boyd Munro took them to task attempting to get portable units approved at about $500 a throw.
CASA would not budge so Munro went to the opposition and got them to disallow the requirement. He succeeded and our industry has saved tens of millions since then!
