We have traveled down this road discussing something that is nothing more or less than using common sense in how we should view the most modern most accurate navigational aid available to the masses at a price that is affordable for all.
Lets not quit here, lets keep this going and chuck another item or two into the box.
When flying long ocean legs or over desolate areas of the world where HF is required we seldom if ever use it because we carry satellite phones that are reliable and give us crystal clear communications anywhere on earth should we be unable to communicate via the normal oceanic radio frequencies....either direct or by relay through other aircraft.
My question is this displaying poor airmanship?
