Touchdown! Greaser!
A question here for my knowledge - you say if you're heavily iced, zero configuration changes (including gear), but that you haven't been in icing heavy enough to not dare lower wheels as you cross the numbers. So for you, how do you proceed? I generally push the gear lever down at the FAF (but I'm generally not iced). Are you suggesting waiting until over the numbers, then pushing the gear lever?
Thanks for sharing your advice/experience.
Like so many other aviation questions the answer has to be "it depends". If you are iced up so bad that you're coming down 500 fpm or more at full power with the gear in the wells you're likely better off leaving them up. But if you have enough power to hold altitude with the gear up I think you'd be well advised to lower the gear long before reaching the runway. The best option would be to fly an approach to a very long runway and stay above 500 AGL with the gear up until almost over the theshold. Then drop the gear and descend with excess airspeed and hopefully reduced power so you can add power near the runway to slow the descent. I saw the result of one pilot's mishandling of an iced up approach in a brand new Baron a few years ago. He didn't have all that much ice but also didn't bother to use the boots on final. As far as I can tell, he simply didn't add enough airspeed and stalled about 30 feet in the air a hundred feet short of the runway. The subsequent touchdown removed the landing gear and bent the fuselage and wings.
