Hands ON the thrust levers.
This is compulsory and part of SOP's with my airline. Whenever we're flying below 2500 AAL we must have our hands on the control wheel and thrust levers.
Regardless whether we are about to make an autoland or a manual landing.
And overriding the force of the autothrottle is not hard.
Even better to disconnect the damn thing if it erroneously pulls back the levers of course.
