Hi All, I've spent so long on this issue now that I thought it was worth a punt on the forum. My issue concerns an addon aircraft that has full MCP control and I am trying to interface some hardware. What I really need to know is if there is an Event ID that selects the vertical speed option? I can find ID's for things like AP_HDG_HOLD_ON but nothing for selecting AP_VS although I have found the INC and DEC for the V/S. Also missing is HDGSEL...Am I looking in the wrong place or do these Event ID's not exist? Any help greatly appreciated.Cheers, Squirrel

HelloWhat aircraft are you trying to interface with and what hardware are you using?If you let us know that information we may be able to help.

Thanks Mad Dog, it would be helpful, silly me... however I've found a config util I forgot I had so will try that first before wasting anyones time. Thanks for the reply :)
