The CVS now has new vertical-speed indicator and heading-indicator support, to go with the existing support for the attitude-indicator and the altimeter.
The VSI and ALT are connected to the static port. When that port is blocked, the ALT will freeze at its current altitude reading, and the VSI will gradually settle to zero; that's particularly nasty, because the two instruments will agree (no climb or descent). The AI and HI are powered by the vacuum pump. When that pump fails, the AI will gradually settle down and to the left, while the HI will simply get more and more sluggish until it's basically still. For these gauges, the failure is very slow and subtle. The HI also precesses 360deg/day when actually spinning -- i.e. if you could fly for 24 hours straight and refuel in the air, it would do a complete circle. Note that it is not necessarily lined up with the mag compass when you start the aircraft.
