MGL Avionics User Forum

Hi all.

I'm just in the process of getting my head around the requirments for installation of a Trig TT21, coupled with an SP12 GPS, via the MGL interface to an iEFIS lite.

My question is (probably a really dumb one), will the iEFIS provide the TT21 with an altitude via CAN or do we still need to plumb the static port on the TT21 into the aircraft static system.

Thanks in advance.

Cheers.

Peter.

Yes. I have a Sandia transponder that gets its altitude from the efis lite

Thanks for your reply. Let's hope that works.

The transponder gets all it needs via the CAN bus from the other devices including pressure altitude for the encoder.
