My Ercoupe is due its 24 month transponder/ static check this month. I fly in the Washington DC ADIZ but always under Class B. I also fly into Class C airspace. I was told there are 2 types of checks. One is for a VFR transponder check wich correlates the altitude readout with the transponder. The other is a full static check for IFR certification which I do not need.
In contacting 2 avionic shops one said they never heard of the 24 month transponder check and they do the full static check for $ 200. The other shop said they did both. $ 197 for the VFR check and $ 250 for the full static check. In reading some threads on the AOPA Forums I see some have listed Transponder checks for only $ 45. Could someone clear this up for me ? Jim Truxel, N3439H, 415C, Serial # - 4064, KFDK
