There's no solid background for that comment, it's how I feel. here's why I feel that way. We all know we have 7.5Gs available at 350kts? sure, will you pull that in the break even if you're at 500kts, I hope so. The difference is that you'll be below corner in less than a second if it's initiated at 350, at which point you'll be capitalizing on the superior turn radius of the hornet, and you'll end up .4 abeam? Can we all adapt and overcome and just play the turn to end up closer to 1.5 abeam, sure. But let's not call it a break if that's what we're going to do, let's call it a turn to downwind. In fact at 350kts, if you pull even 4Gs, forget about 7.5, for more than 90* of turn you'll probably end up a mile abeam, still entirely too tight to make a safe approach. I have the utmost confidence in even the most junior aviator that by the time he reaches the Hornet FRS he'll know to ease the pull or end up taking it around. The issue with young pilots, and even some seasoned guys, is that naturally the stick input required for a safe and expeditious roll rate changes with airspeed. The aft stick input required for a safe smooth application of G changes with airspeed as well. As long as we're not ham fisting everything will be fine. But if we are, there's the potential for a guy to reef the nose around trying to look $hit hot but forgetting he's being legal today, and ending up in tone at 800feet.
Ok, here's the summary Brett. I believe that in order to execute a safe "break turn" at low altitude, a jet must have the airspeed required to apply full aft stick into the lap achieving every available G the airplane will give you for a full 180 degrees of turn and still be above corner when he rolls out. It's the only way such dynamic maneuvering is safe at such low altitudes. How is "aerobatic" flight defined, and how low can we do that? What is minimum maneuvering airspeed in LATT? If at any point in a "BREAK" turn you end up below corner, then in my opinion, you weren't going fast enough when you started it, and you should have simply made a left turn, not a break turn.
