    during a short test flight I observed the following:

    1. When approaching the selected altitute while descending in VS Mode -800 ft/min the FMA changes to HOLD. During the last ~300 ft the Vertical Speed increases up to 1700 ft/min before reducing again. (Pic 002, 004, 005)

    2. Seconds later I pushed the APPR/LAND button to intercept the ILS- and the aircraft instantly captures the ILS although the localizer is still too far away. Also it should maintain NAV mode until intercepting, instead the aircraft turns left. (Pic 007)
