Ha, I don't know how much they know, especially when they don't put a real ILS in a 35 million dollar Hornet. (The one installed, bullseye, works at the carrier and certain Navy fields only). Emergency + low fuel + real crappy wx + cross country = ejection = pissing away 35 million dollars, which is probably the same or less than what it would have cost to put the stupid thing in the fleet jets for starters... just my rant. So they know a lot, but not THAT much.
And with my 300,000 dollar tax payer education from a small engineering school in Maryland that happened to include three years of aerodynamics, I'm still not seeing how "balanced flight" and a centered ball for a jet aircraft such as the Hornet are not on opposite sides of =. I think maybe we are getting the terms "balanced flight" and "zero sideslip" confused. You can fly on one engine and have a centered ball, but you will have some angle of beta (not negative thrust in this case, but yaw angle) in order to fly a straight line over the ground. But then again it has been awhile...
