I don't disagree with the general sentiment and I am glad that I did my PPL through to CPL pre Ipad and GPS. To be fair to the younger generation though I don't think they are even given the choice of learning techniques that doesn't involve technology. Even the basic trainers have glass cockpits. I always had a quiet chuckle to myself when the bloke in the LHS pulled out a calculator to work out ToD. Reference weight is 60t add 1nm for every tonne above and then add blah blah blah for wind. Then ATC would get you to slow to 250kts as soon as you commenced descent and there was no longer time to pull out the calculator. I dont see it done anymore as they just rely on the vdev scale.
