I think the general consensus is you feather the engine no matter what. Where people disagree is what to do with the power on the operating engine. I flew seminoles for almost 3 years in temperature and humidity conditions that regularly would give you -100 to -200 fpm single engine in the summer. Heres the thing Toilet: if you are on an approach (an ILS for example) and maintain your airspeed at Vyse (88kts) throughout the approach. Assuming no wind, you WANT a descent rate of roughly 400fpm. So, the idea of just mindlessly shoving the power forward will not only cause you to loose the glideslope, you will more than likely loose the LOC as well as you deal with the yaw. Not to mention that you are trying to secure the dead engine while all this is happening. I think most of us who fly professionally realize that there are VERY few situations where a kneejerk reaction is what is called for. Generally a slower, measured response is the best way to handle any situation. Also, I am willing to bet most people on this forum have time in a PA44 and are at least somewhat familiar with its single engine handling characteristics.
