MIm20c Posted May 8, 2021 Report Posted May 8, 2021 The other day approach at a class C airport said my adsb was not outputting correctly. I checked on flightaware and sure enough speed output is rapidly changing/oscillating between 100kts to 200kts. I have a 430w and 330es, I’m guessing a wire/connection problem but I’m not sure. Any ideas?
ArtVandelay Posted May 8, 2021 Report Posted May 8, 2021 Did the route show correctly? Both speed location comes from GPS.
MIm20c Posted May 8, 2021 Author Report Posted May 8, 2021 Route and altitude both steady and accurate.
Mark89114 Posted May 9, 2021 Report Posted May 9, 2021 Does it broadcast speed? Or location where it calculates speed, time distance calculation? I have seen that same squiggly line on my tracks, just not as extreme.

MIm20c Posted May 9, 2021 Author Report Posted May 9, 2021 I was burning 6.5 to 7 gph so TAS was pretty slow…~15% off normal cruise.
