Hi Tarbat & All,

I am running my RB with "Auto Set QNH" with Advanced Filters in use for a couple of hours now and it looks that my "advanced filters" problem is solved.

Tarbat, thank you again!

Glad that's solved for you John.

Airnav, I guess there's a bug somewhere in Radarbox that can't cope with negative altitudes.

Hi All,

For your information: EHAM is situated BELOW sea level. Maybe that could be the reason of negative altitudes with me....?

And even airports above sea level will show aircraft at negative altitudes just before touchdown on high pressure days, assuming no correction for QNH.

British military airfields do use QFE.  Most civil commercial airports use QNH.  Of course, there are exceptions.
