TO: FreeFlight Systems’ 1101 GPS/WAAS Sensor operators and installers

FROM: FreeFlight Systems Customer Support

SUBJECT: Notification that the FreeFlight 1101 GPS WAAS Sensor, part number 84736-01-0315, is intended for VFR only.

PURPOSE: To notify Operators and Service Centers that the FreeFlight 1101 GPS/WAAS Sensor, p/n 84736-01-0315, is not a certified WAAS sensor and should be used only for VFR.  The FreeFlight 1101 GPS WAAS Sensor was developed as a low cost, uncertified sensor for the Experimental Aviation market. It has come to our attention, however, that the units were sold as “equivalent” to our FAA-approved TSO C-145a (Class Beta-1) 1201 sensor and therefore have the required integrity to support L-Nav/V-Nav approaches under IFR conditions.  This information is not only inaccurate but potentially dangerous, as an approved Beta-1 sensor is intended for lateral guidance only.

ACTION: Notify Operators and Dealers that the 1101 GPS WAAS Sensor is intended for use as a VFR sensor and should never be used to fly an NPA or L-Nav/V-Nav approach, except as a reference under VFR conditions. It is recommended that all installations utilizing the 1101 sensor be placarded for VFR USE ONLY.
