I try to remind myself that iFly is only a tool. But it works so well and does so much, that I admit that I've become dependent on it.
It's hard to appreciate how much one relies on it until something goes wrong with it (or your tablet), etc.
That doesn't happen much anymore. But I remember the helpless feeling I had while flying home last year when an earlier iteration of iFly & Stratux kept crashing in flight. I was dodging icy cumulus in VFR conditions. I was over familiar terrain. But still, not being able to see what was ahead on RADAR or get METARS at the touch of a button was kinda intimidating. I might panic if I lost all that info in hard IFR in nasty weather.
Sure, I've flown without all this help for 35 years and could've gone back to the archaic method of calling FSS and asking a "specialist" to interpret RADAR for me. But for me, flying without iFly is like flying wirthout glasses. I feel blind.
(So, as with my glasses, I take a pair of iFly tablets with me when I fly.)
