MLS-12D is quite correct. In the Golden Days of flight, this was a common and safe way of non gyro IMC let downs, and so long as you have enough room between the cloud and the ground, what is the problem? You'd have more problems trying to keep control with no gyros and flying down through IMC, so why not put the aircraft into a spin, in a known direction before you enter the clag?
