When selecting an LDA approach, the approach defaults to FLS following the runway extended centerline which should not be the case. An LDA is simply an offset LOC approach using ILS symbology with a visual turn to final.
In addition, the aircraft may auto-tune a garbage ILS frequency with the wrong frequency and wrong identifier for the LOC.
Manually tuning the LDA by either using its identifier or its frequency does not work as it should. Even though the RAD NAV page may correctly identify the LOC, the PFD doesn't display the localizer and the approach must be completed on NAV/APP-DES mode.
Reference: this video at around 1:41:20: The aircraft is set up for the LDA 23 approach at RJTT with the PFD indicating "ILS" as expected.
