This video was in my "suggested videos" list on YouTube. I had never heard of attitude indicator error until this. Is this only in the MM style indicators or do all gyroscopic instruments have this issue? I always climb on airspeed.

I had never heard of it either. Here is everything you want to know...
http://www.theairlinepilots.com/forum/viewtopic.php?t=905 Explanation of error starts about half way down. ETA: "Gyro Erection Air driven artificial horizons are made pendulous, with their Centre of Gravity below the suspension point. This is so that they settle in their gimbals in a nearly erect position when not working, to reduce erection time on start-up. Once the gyro is rotating, simple pendulosity does not help with erection. Pendulosity is only there to help before start. After start it induces unwanted errors." |
| I remember learning about this, or at least something similar, when doing my instrument training. Is this the same principle as if you sit and look at your lap and have your safety pilot accelerate in straight and level flight it gives you the feeling of being nose up when you are really level? |

If you have a frozen over pitot static system, your airspeed will increase as you climb, even if you are slowing down. Do some reasearch on this subject and you will understand why the best practices followed by the pros include a good understanding of the pitch/power charts for most standard configurations. |
