The AV-APA (analog port adapter) accessory enables aircraft owners with legacy autopilots to replace their older, vacuum-driven directional gyro with a lighter, digital AV-30, potentially removing their vacuum system entirely.The AV-APA emulates the analog heading signal used by legacy autopilots to provide heading hold as well as the ability to follow GPS tracks from a portable or IFR GPS.This AV-APA (EDMO# UAX9010201) is for experimental aircraft and compatible with the AV-30E
