It’s my first time here, apologies if I’m posting this in the wrong place.
My plane is a new-to-me Gen1 SR22 and has a Stormscope and after-market Aspen PFD. I’ve doing my transition training, and I notice the Stormscope says “lighting ahead” a lot. The map on the 430w shows a string of lightning straight ahead and behind me. And there’s no lightning around in the sky.
There’s also this faint siren like noise that goes off randomly. I think it’s related to when the Stormscope thinks there’s lightning, but I’m not sure.
Finally, my PFD sometimes says “AHRS miscomp”. The autopilot still works when it says that. I don’t know if this is related, but I figured I’d include it just in case it strikes a thought for someone.
I’ve asked the CFI doing the Embark training, but he just says it’s fine and he’s not sure what is causing it because the plane is so old and the PFD is after market.
I mentioned the “lightning ahead” and the “AHRS miscomp” stuff to the local Cirrus maintenance place at the last annual when I bought the plane. They checked it out and said “everything is functioning as normal”.
I’m a new private pilot, so is this a big deal? I feel like it is, but the CFI makes me feel like it’s not.
Also, since maintenance previously said everything is functioning normally, but it’s not, any tips for me to better explain the issue so they can find it? Or any helpful wisdom when in a situation like this?
Here is a photo of the lightning on the 430w’s map:
