Another mystery?
Does anyone know what the parameter 'TLU Position (DA)' shown on page 112 of IR no.3 (English) stands for? Since with 1300 recorded parameters it is inevitable that the report must necessarily involve a selection of the relevant parameters, showing this parameter means that somebody thought this one might be relevant.
On page 89 we read at 02:10:18: "The ‘TLU 1 availability’ and ‘TLU 2 availability’ parameters become NOT AVAILABLE" and the traces of these parameters are shown on page 107. Since this time roughly corresponds to the end of the initial 10 second speed monitoring process, I thought that TLU could stand for RTLU (Rudder Travel Limiter Unit). But what then is TLU position?
