Most just use it briefly as a toggle to get better roll, and then turn it back on before the target gets in the crosshairs to let the ship readjust, giving them more precision. There's a few that don't, but FA off is a lot less forgiving, as you've found out. Try as you're turning to just bump it off for a second and let it back on, and you'll see how it affects the turn. Using lateral thrusters instead or in addition to will also aid in the turn. Each pilot has their own preferences, that's what makes player encounters exciting and tense.
