Aspen MFD1000 pro /with battery back-up install/Removal of vac system

[The201pilot]

Has anyone in Canada removed their vacuum driven system from a 201 with the install of a pro pfd/mfd combo with battery back-up ?

I currently have the 1000 pfd pro installed coupled to 430waas..and will be installing another 430waas and mfd with battery back-up...

Should this not enable me to have the vac driven equipment removed or am i being misled, any of you folks have some experience with this ?

Lets disregard that the autopilot is driven by the attitude gyro for now as it will be replaced in the near future and rarely is used now..

I think the Aspen STC requires an external AI. It can be electric I believe. If you go for the extended battery pack version of the Aspen, I think you can lose the ASI and altimeter.

I'm not an expert on these regs but I have a dual Aspen with battery backup and the avionics shop insisted that I had to maintain the vacuum driven AI.  They wouldn't let me change to electric either.

As mentioned above, Aspen's STC requires a backup AI.

 

As for a vacuum or electric, that has nothing to do with Aspen. It has to do with well, lets just say, what is FAA acceptable in your plane.

...as far as I know dual Aspen has to be Evolution 2000 instead of 1500, then you will have the redundancy needed...but if I remember correctly you will have to keep your AI. My opinion is to keep the backup AI on vacuum...
