Yes you are right. I have learnt that thanks to you. In the Jepp, the LDA is specified for 9L, and a note explaining that some 200 m are not usable for LDA computation. And there is no displaced threshold. But the important thing is that every time you don't see an LDA in that field it means that you can use TORA as LDA. Otherwise use the specified value.
This thread was worth it, guys
Cheers!
