Default Debunking Glider Spoiler Turns Causing Spin Thinking

How come nobody ever states that these G loading increases are for

the flight path angle?


The speed at which the wing stalls depends only on the G loading, not on the attitude with respect to gravity or the earth. Of course if you're in an unusual attitude then your speed may be changing.

As long as you keep the angle of attack constant (which pretty much means the elevator and therefore stick position), you don't have to think about how the speed or the G loading are changing -- they'll change together in sync. As long as you stay below the speed at which the G loading will break your wings off anyway.
