Encoder (Blind Encoder)

Make certain ATC knows where you are! Use a Transponder and Encoder for Mode "C" operation.<BR><BR>There are two types of Encoders: Encoding Altimeters and Blind Encoders. A Blind Encoder is much more cost-effective, so unless you need to replace an existing Encoding Altimeter, we recommend a Blind Encoder.<BR><BR>A Blind Encoder is basically a remote altimeter, with the pressure always set to 29.92". You don't see its reading, but it is transmitted to ATC through the transponder.<BR><BR>Even though we are in the used avionics business, we find that a used Blind Encoder rarely makes economic sense. By the time we repair and certify a used unit, it's usually within a few dollars of a new one. As a result, we usually supply new Blind Encoders.<BR><BR>Our customers have had good success with Trans-Cal, but if you have a preference, we can supply Blind Encoders from ACK, Ameri-King, etc.<BR><BR>Regardless of the Blind Encoder you choose, you will need a Transponder to use with it.<BR>
