Radioaltimeter erratic.

[AX47]

Yesterday we flew Attack Mission on Kola Map. First legs was cruise on 2000m STD. Sea target QFE was 1013 so STD was remained on Altimeter. Radio Altimeter was set to RHM during whole flight.

When descending to 700M the Radio Altimeter value drop down to 180 m still in RHM. Barometic altimeter was at 700 m (see picture)

When checking Radio Altimeter it seems that there is a BUG above 500 m as the value follows  Barometic setting and not radio Height value.

PLS EXPLAIN

Can you reproduce this issue on the Caucasus map?

Do you have a short track of this issue?
