I think the only aircraft which shows the correct icon (aircraft instead ‚grey disc‘) is the sr22 by working title… who would have thought. This has to be pushed to each and every dev who uses g1000.
Why on earth this bug is still on the c172 for example is hard to comprehend.
Fix it consistently for all planes and save us from the situation that this is still a thing in months (or years) to come. Please!
