Limited Panel Flying

[KCDW]

Currently prepping for my IMC course next month, armed with Thom number 5 and my trusty Microsoft Flight Simulator!!

Now I understand that the course includes limited panel flying for both Gyroscopic failure and Static Vent Blockage. However, Thom totally concentrates on the former, with absolutely no guidance on flying with the latter.

This is curious, as frankly I can't figure out how anyone can stay alive with the VSI, ASI and altimeter failed while in IMC.

Thom's only guidance is to switch to the alternate static source, or break the glass on the VSI.

So the question is, do you only get trained on flying with the HI and AI down (gyroscopic failure), or is there a method which Thom doesn't go into?

Hope you can help

Thanks
