As a follow up note, the UI on my Fly app version has a hex icon just above the takeoff icon. The hex icon controls 'safety features' - it toggles between avoidance modes and turning off slew: the order is something like BYPASS, BRAKE, SLEW ... when slew is off, the hex icon loses the two vertical bars in the 'ring'. It seems Gold is bypass mode, White is brake, and the missing bars when the slew function is off.
