I) The installation with theGNS530 was previously FAA approved,and2) All interfaces between theautopilot and the GNS530 are eitheranalog or ARfNC 429 roll steering(GPSS).The autopilot must be limited tothose operations for which it was previouslyapproved when interfaced to theGNS530 (e.g. VOR, ILS, LOC, BC, andGPS nonprecision). GPS approaches withGPSIWAAS-based vertical guidance(LNAV+V, UVNAV, and LPV modes onthe 400W /500W) are not authorizedwhen coupled to the autopilot.There are also special provisionsfor encoders and audio panels if eitherare not induded in Appendix G. If theirinstallation data was previously FAAapproved when interfaced with the previousGNS530, then additional approvalwill not be required.Other considerationsThe current software in the Sandel3308 does not support vertical CD! ofGPS data, so the analog inputs to thevertical CD! need to be added and the3308 needs to be reconfigured to reflectthe change. Dual 3308s and dualGarrnin W GPS are not supported.Depending on how the originalinstaller interfaced the GNS530 to theautopilot, one of the wires may have tobe changed. If you have a KAPI 40 orKFC225 autopilot, you will have tochange one wire.The Garmin GDL49 is not supported.[ understand that Garmin gives a goodcredit to replace it with a GDL69. Thisdoesn't help the WSI box owners.Flight checkFinally, a post-upgrade flight checkmust be conducted to verify properoperation of the installation and a newFAA-approved supplement needs to beprovided with checkmarks indicatingwhich sections apply to the installation.Total expenseAll in all, J estimate my installationwill require about 20 hours of labor and$1 ,023 in hardware, in addition to theGarmin $1,500 upgrade, for a IOtal justover $4,000.Appendix G information and diagrams providedcourtesy of GorminJohn Collins is a commercial pilot with4.000 hours.
