Good point on the units, Mark. The rest of the weight gauges show kg here, so I went for kg too in the PDCS. Is yours set to lbs?

Yes, EZCA certainly helps, but a popup is different (for me), even with TrackIR and things, some gauges are better as popups in my eyes (pun intended), especially the ones with a few buttons and some data entries necessary. Same for FMCs on the 757/767 for example.
