I fear that you have the cart before the horse. If a yaw departure has occurred then there is no option for acceleration to get out of the situation for Vmcg and only descent for Vmca ... the very thrust upon which you place your salvation's reliance is the same thrust which is taking you to your accident .... the thrust must be reduced to regain control. Like it or not ... we can't overcome the realities of the physics involved.
JT, I agree with your statement and it reinforces some of my earlier comments about directional control issues that have been experienced.
Remoak, I also think I get your point, if the a/c has accelerated through Vmcg or Vmca (once in the air) and has been stabilised directionally then yes yaw departure risk disappears.
However, if the directional issue hasn’t been stabilised then the acceleration will serve to exacerbate the departure, and as JT said, it can be all over pretty quick unless that thrust is reduced.
Tough choice to make I know, if you’ve got trees rushing up at you....
