I am using Andy Karlstetter's B737 panel in the POSKY 737-600. (The POSKY-designed panels for this plane are nla from POSKY). I am running FS9 in XP. The panel works quite well except for problems with the VSI control and, less importantly, the A/T indicator.Problem is that the VSI can't be activated unless the ALT HOLD is also activated, the opposite of what should happen. When the VSI is active, its LED (if it has one) stays off. Once the set altitude is reached the VSI re-sets itself to 000, and the ALT HOLD LED switches off.The A/T works quite well - less accurately and slower than PMDG but the LED, if there is one, does not illuminate. I am not sure if there is an LED for this switch in this plane - if not I would like one!All the other MCP controls have LEDs which light up when the control is on. Can anyone advise, please? John

Hello Jonh!I'm not familiar whit the panel you're talking about, but looks like it is coded to simulate the V/S armed mode only: The V/S is armed if the ALT HOLD is already engaged and a new altitude is selected. The V/S can be used independently from the ALT HOLD mode but you have to code for it if it isn't included in the panel you are usisng as well for the V/S and A/T P/B lights, but read the documentation included whit the panel first to make sure you have the permision to modify it, other wise you must code your own MCP.BTW, as far as I know the ALT HLD P/B light goes off to indicate the mode cannot be deselected (at selected altitude) and is on when it can be manually deselected.Javier

Thanks. Not sure what you mean by A/T P/B lights and ALT HLD P/B light. I read P/B as push back - maybe I am flying too much IVAO. I guess I am missing something obvious.

P/B stands for "Push Buttons", at least in my Avionics jargon :(, so I meant P/B Lights the two green/yellow lights tha turn on and off upon the buttons when a mode is selected/deselected.Javier

:( By coding, do you mean xml coding. Xml is not my strong point. I've done a little with airfield approaches - not with gauges.

Then I suggest to look for anothger panel. Sorry I don't know of one but you may serch the File Library. Javier
