holding the plane altitude - Xplane 11

[nkazanji]

Hi all,

I tried few online profiles for Cessna c172 but non of them will do the following scenario:

1- Altitude set to 3000 feet.
2- VS is set to 500

when the plan reaches 3000 ft. it will continue to climb and VS still showing 500.
can some one advise on how to automatically hold the altitude to the selected setting and show the VS=0

FSUIPC4 has such a feature and works well with FSX.
but couldn't find how to kame this happen in X-plane 11

Please help

Regards

Nigel
