Dear community, I would like to ask, which autopilot vertical mode do you use in climb? I am succesfully using C550 with famous ISG mod v.1.7. prepared by Janek Bln, however would like to know, how do you climb with this bird? I have to use V/S mode, as using IAS mode is not reliable, at least in my case. The plane is jumping up and down, unable to keep selected IAS during climb, even if properly loaded and trimmed. Did I miss any patch prepared by Bert / anyone else or is there any other solution? Maybe I missed something in this forum. Many thanks in advance for the advice.
