Cannot select ILS approaches at OLBA

[NAVData]

Yes, this is a standard ARINC424 coding rule and yes, when a missed approach is starting prior the runway threshold - an ILS is coded as LOC. But there are only a few world-wide. OLBA is one of it.

In April 2021 we had posted a own FAQ exactly for this question:

FAQ - ILS Missing, only LOC provided for Missed Approach TURN prior to RWY

Where an airport ILS Missed Approach procedure requires a TURN away from the final approach course prior to the runway threshold, our data provider Jeppesen codes the ILS as LOC in our FMS Data. This is in accordance with ARINC rules. A typical example is OLBA, where you see the Missed Approach course leave the final approach course BEFORE the runway - so Jeppesen codes the ILS approach as LOC. [image]

… but as I have written, this is ONLY for the selection in the FMC/S or any other navigation-facilitiy. That has nothing to do, that you can´t use the glideslope … When you select the frequency, you will receive the glideslope as normal. For an coding ILS approach you must overfly the threshold and that´s not the case here and therefore it can only be coded as LOC for the nav-systems.
