Getting my head around the yoke button function bindings tutorial video I summarised it as follows for reference -
BINDINGS
Requires 3 buttons to be assigned on your HOTAS or Yoke. These bindings will be set to custom ones at some future point in time when Asobo release new blank variables for devs to use.
— MANUV BUTTON (RHS YOKE) —
MANUV BUTTON : {bound to} : SMOKE ON (ON PRESS)
MANUV BUTTON : {bound to} : SMOKE OFF (ON RELEASE)
FUNCTION:
This button is used to temporarily disengage AP so you can set pitch with yoke then it engages AP again on release using new value for pitch.
EXAMPLE:
if AP ON, with V/S mode press & hold MANUV BUTTON then use yoke to change pitch to what you want then release MANUV BUTTON, and AP will enable with V/S using new pitch value.
— STEER LOCK BUTTON 1 (center console white STEER LOCK button replacement) —
STEER LOCK BUTTON : {bound to} : TOGGLE TAIL HOOK HANDLE
{note: center console button may no longer toggle}
— STEER LOCK BUTTON 2 (ORANGE BUTTON ON LHS OF YOKE) —
STEER BUTTON : {bound to} : G LIMITER ON (ON PRESS)
STEER BUTTON : {bound to} : G LIMITER OFF (ON RELEASE)
FUNCTION:
Orange yoke button is a STEER ENABLE function while pressed when on the ground, and disables steering on release.
Note: It is an AP disengage button/function when airborne.
— PITCH SYNC BUTTON —
The yoke PITCH SYNC BUTTON only works when AP is DISENGAGED (in MANUAL MODE), it is disabled when AP is on. It is mapped to default sim “PITCH SYNC” binding/function.
