One thing that has changed is the proliferation of controlled or prohibited airspace. Modern navigators are a very valuable aid to avoid busting airspace. Let’s not forget that every bust increases the pressure to further increase restrictions on light aviation.
So you may feel all self satisfied that you are eschewing modern navigation aids and doing it the traditional way, but when you get the call from the regulator you deserve what you get because you by choice did not use every navigation aid available.
The foundation principles of navigation haven’t change but how to apply them have. GPS navigators can only be properly used if those principles are understood, but just because you can do the old school map with a PLOG doesn’t mean you automatically are fully ready to properly use modern GPS navigators. I would suggest that as a general comment flight schools are not doing a very good job of preparing their students to succeed in the real world.
