Raffi Posted November 28, 2023 Report Share Posted November 28, 2023 Hi all , I'm updating the interior of my bravo and I found that the vacuum tube is very oily. Apparently this needs to be replaced after several years because the oil that the tube releases can ruin the vacuum pump. The only thing that's running on the vacuum pump is the AI , there is an electrical AI backup and there is an Aspen Evolution screen. So I thought instead of replacing the tube, lets get rid of all the vacuum pumps, tubing... The problem is that the autopilot is coupled to the vacuum AI... Any reliable suggestions that dont make me bankrupt? Kind regards Ralph 1 Quote Link to comment Share on other sites More sharing options...
PeteMc Posted November 28, 2023 Report Share Posted November 28, 2023 I'm not sure of the current cost of the Aspen EA-100 adapter, but that should work with the KFC150 - assuming all the other variables are there. Check with your Avionics Shop, it might be the easiest way to go. Also check that the electrical AI is or can be the backup to the Aspen and that your old vacuum AI isn't (currently) required. I'm assuming the two AIs were there before the Aspen, so it is possible the vacuum AI is the required one and the electrical on might just be there. Doesn't mean there are not other option, just make sure that's not a "gotcha" you were not expecting. Quote Link to comment Share on other sites More sharing options...

That's what you will need to connect the Aspen to the KFC-150. PM me please AlexSent from my Pixel 7 Pro using Tapatalk Quote Link to comment Share on other sites More sharing options...
Pinecone Posted November 29, 2023 Report Share Posted November 29, 2023 FYI, my plane is currently running an Aspen 1000 Pro to KAP-150 using the EA-100. Works fine. I have a G-5 for backup AI. 1 Quote Link to comment Share on other sites More sharing options...
