Skeptical of the ADS-B check tool on my iPad until it flagged a bad transponder in 20 minutes
I figured the iPad app was just a toy compared to the ramp tester, so it sat in my bag for months. Finally tried it on a Cessna 172 at a shop in Tulsa and it pinned a weak transponder reply that I'd been chasing for two days with the bench gear. Twenty minutes, no hangar time, no dragging the test set out. Anyone else using these tablet tools for quick squawks, or do you still go straight to the certified box?
