Hello:The info on your site says it works with freeware 737s that follow a certain convention. Do any payware besides PMDG (like Wilco's)follow this convention so that they can be used with the default edition?K

Hi K,Payware aircraft usually use a large number of 'custom' variables not documented in the Microsoft Panels and Gauges SDK. These are variables that, in the absence of an custom SDK, I cannot read or write to.Most, but certainly not all, freeware aircraft conform to the Microsoft Panels and Gauges SDK to a much higher degree, meaning that I can read and control the various switches on the aircraft.Hope that helps,Bryan

Bryan: OK. I understand. Thanks so much for taking the time. Kaydub
