Hi,  
the point is not, that this procedure doesn´t exist - this procedure exists for sure and will also be used as you have discovered. The point is, that this procedure can´t be coded for the data as an ILS approach due the ARINC424 standard rules (missed approach starts prior the runway threshold and follow not the runway heading).

Compare the ILS-Z 15 approach with the ILS-R 15 approach:

Can´t be coded:

Can coded and therefore included in the FMS data:

So, that´s nothing what we can reconsider … that´s simple coding rules. But you can fly this approach without any issue, as in the reality. So, there is no stop to fly it … but right, it´s not a “one button” press.

Cheers,  
Richard
