I think aircraft cockpits could benefit from the addition of more teak.
Not that I don't enjoy flying as a job, the jury is still out on the career aspect of it, if I made a lot more money I would even do it as a hobby, but sailing is my true passion. I had moved to the coast to study sailing and get my captains rating, when I found Rod Machados book, took an intro flight lesson, the rest is history.
I recently wanted to get my ASA ratings to charter larger boats. I was inquiring on a sailing forum about the navigation course and asked if the course covers "radio navigation" to which the sailors replied "Huh?" When I learned so sail Loran was still around, and came in awful handy in the fog.
A majority of my flying is in Mexico, where there are no GPS approaches, not that I have an approach certified GPS anyways. There are also Jet routes that the VORs are so far apart that you either need a GPS to follow them or ded reckon between the stations. I have had to shoot an NDB approach into Ensenada a few times. I have even shot a few NDB into Sun Valley a few years ago before Ameriflight splurged for GPSs in some of their planes.
I for one will be sad to see the ground nav aids go. I think it will create a generation of magenta line flying, MFD watching, situational awareness lacking (without GPS) Pilots. I know this is how it is done in the big planes already but most of the pilots a generation or so ago, spent some time in a /A plane and had to ded reckon at least once to get their PPL and had to navigate using a VOR and an airway.
If the removing of ground based stations occur, the future will be two GPS cockpits where you back up situational awareness by looking at the other moving map? If I recall (maybe 135 only) you can't have a GPS approach as your sole approach at your alternate. Does that mean in a future world with only GPS nav available, all alternates will have to be in Mexico?
