Hello LandSeaAir69,
that is a fairly commen experience in the BK117 - had it with differnt machines - always at the same position.
Some airports are more prone to this behavior than others.
Itīs an very old computer in the autopilot......
Just be prepared while on the ILS, especially passing the OM - and either go around or reset the AP

Hi,
me again - had a talk to a fellow pilot - itīs actually not the OM causing the disturbance, itīs the RAD-Alt setting in - which is about 2000 feet (on some places the position of the OM)
So have a look on the RAD-Alt or knowing where you pass the 2.000 feet, to be prepared!
