Interesting discussions about EFB vs. Paper charts etc. My instructor is of the opinion that I should "know how to do it all manually without hesitation, but also know how to use the modern technology since that is what you will use going forward". So, in my case I planned my last two XCs using AOPA's online flight planner, filed online using that, printed the navlog from that. And ALSO plotted on a paper chart, and created and calculated (with instructor there, no cheating) the paper navlog, paper W&B, and called FSS for a weather briefing (even though I had the online briefing and printed it).
Frankly, being in IT as a profession - but also being 48 years old, I see both sides and WANT to be proficient in both. I think the analogy to paper maps in a car, vs. my phone with google maps or a Garmin GPS is a great comparison. I grew up reading maps, planning trips, etc with paper. I still prefer to do the "overall plan" view on paper. But, I use my phone/gps far more and really never pull out the paper when on a trip.
The difference/issue is - I feel - in that planning/overview stage. When I go on vacation and get in the rental car, and just slap "hotel xyz" in my google phone gps, and it takes me there, I'm really relying on that tech to work right. AND make a lot of decisions for me. As opposed to say, deciding to drive 2hours to some attraction the next day, where I will almost always view a paper map or online equivalent ahead of time, and plan a route. Then let google and gps help me there (or more likely just track me as we go).
I personally view flying the same way. I LIKE my paper map for planning purposes. I like the level of detail it offers for VFR flights as well. The GPS/EFB is great for confirming I'm on course, and great for other things (calculations) too. But I still like having that paper around. Guess it's just the almost-old-fart in me. (Or I'm just a student still and will out grow it).
