So Centaurus and all, I must be flying with a good outfit if they ground an A/C with a U/S XPDR as soon as it becomes apparent by loss of radar identification.
I also agree with being on the correct frequency (if I can work out where the new boundaries are). I also heard someone where I fly to request frequent transponder checks when changing area frequencies TO ENSURE POSITIVE IDENTIFICATION as well as ensuring that the damn thing is working. If it isnt, its time to get out of Dodge and outside class E at least. I will endevour to try this when I start wandering this wide brown land.
