Good day, your findings will surely be very useful. By the way, the approach is still listed in AIP España the official Spanish AIP , but honestly, I don’t rreally know how NOTAMs overide this info. Thanks!

I´m pretty sure, that this is reason, why an ILS approach can´t be coded. I have checked the AIRAC 2301 (so the last, where this notam wasn´t active and here the ILS21-Z was included. So, it´s the glidepath component, which makes a coding impossible … and according the notam it´s permanent, means no end date. Sorry!
