During training, I'll do whatever the instructor says in order to get my license. It just that I tend to get fascinated by technological devices. And I also have this thing about being precise and not wanting to guesstimate based on falliable human perception, and rather trust the slightly-less falliable instruments. But I'll get over that quickly, I'm sure.
Oh, and why is the great circle route "impractical"? My flight is a direct one, so I don't see why they wouldn't fly it from LAX to LHR; isn't a great circle the shortest distance between two points on the globe? Is it one of those situations where shortest distance doesn't equal shortest time?
I wonder why they don't make TCAS or the cheaper PCAS mandatory for all aircraft; it'd significantly reduce the chances of collisions.
