His explanition was it kept the airplane a little more "stable" going down final. He still used the crab to 50ft or so and kicked it out , he just used a few more percent throttle to help centerline alingment and reduce the amount of crab angle down final.
Yes, in this situation, you would reduce the crab angle with the runway. However, in balancing the force vector diagram, you now have unbalanced forces on the aircraft and the aircraft WILL start to drift downwind. This is due to the horizontal component of the thrust from the downwind engine being reduced. When that horizontal component is reduced, you will have to increase your bank into the wind in order to prevent drifting off centerline and off the runway.
Now for landings on ice. I've never done it, only snow. I don't want to land on ice. However, it seems to me that if you are need to use differential thrust to stay on the runway during a landing, this is probably a situation that warrants a go-around and a landing when conditions don't require such cowboy tactics in order to make an airfield. Just my 2 cents.
This type of judgement and thinking a highly congtributing factor as to why Alaska leads the number of crashes and/or occupational pilot deaths (by 20%) over all other states combined.
