This week in IR training I covered no gyro procedures with my instructor. I practiced in the sim under the assumption that the vacuum pump failure would take out the AI and DG. However, the 172SP that I fly in real life has an electrically powered HSI. I asked my instructor whether a vacuum pump failure would in any way affect HSI performance and he gave a confusing answer, suggesting that I would have to un-slave the HSI and fly by the compass. This did not make sense to me.
I actually like compass flying because it feels like a link to the past, but in real life would a vacuum pump failure affect the HSI at all?
