Hi Tim, any further consideration of a QNH input for SD to correctly reflect Flight Levels?
Yesterday (high QNH) SD showed me infringing FL defined Airspace when I wasn't!(I was at FL40 base FL45)
Thanks

Thanks Tim, I'm surprised at the lack of appetite for this, one of the key benefits of SD for me (and others I would have thought!) was the ability to avoid accidental incursions into controlled airspace.

Indeed, your home page claims "Warnings for potential incursions into controlled, dangerous or temporary airspace" and yet it can not do this for the base of airspace defined by Flight Level unless it is corrected by inputting a  QNH.

With a QNH below 1013 it's quite possible to have an incursion into the base of controlled airspace(when defined by FL) as the virtual radar is incorrect.
