IGC-approval for Triadis RU2 and update to LXNAV externalMeans-of-Propulsion recorder box

I am pleased to announce IGC-approval for the Triadis Recorder Unit Version 2 (Triadis RU2) byTriadis Engineering GmbH, of Messen, Near Berne, Switzerland. The IGC-approval document can be found on the IGC and GFAC web sites given below. It includes three types of Triadis Recorder Unit, the RU1, 2 and 3.

In addition, the wording on the external Means-of-Propulsion (MOP) box by LXNAV d.o.o. of Celje, Slovenia, has been expanded in the IGC-approval documents for the LX8000, LX8080 and LX9000. For motor gliders with electric and jet engines (and some quiet 4-strokes), unless the Flight Recorder is positioned close to the engine and/or propeller, the recorded ENL noise figures from the internal microphone may not be high enough to detect engine running, particularly at low power. In such “low ENL” cases such as a cockpit-mounted FR and a rear-mounted engine, para 1.4.2 of Annex B to the Sporting Code (particularly 1.4.2.4) requires an additional MOP sensor external to the FR to be positioned close to the engine and/or propeller. The LXNAV “MOP box” is IGC-approved for this purpose and is an alternative to placing a complete FR close to the engine and/or propeller.
