Printing of enroute chart - not to correct scale

Hi there,

I'm fairly new to SkyDemon and mainly use it on my iPhone and iPad. Recently I installed it on my PC as I wanted to print accurate (scale) enroute charts. I'm currently training for my PPL and am practicing NAV.

On screen, the charts look to scale - I've even measured distances using my 1:500000 ruler and all looks correct. Once printed, the scale is out - losing about 1NM when measured using the scale in the bottom left corner.

I've checked all my printer settings and everything looks correct.

Is this expected or am I missing something? I did try to do the same from the iPad but enroute chart printing doesn't seem to be an option!

Thanks
Rob

That wording might just be us being particularly picky. We'll give it some thought, though. It's because as you cross different latitudes the projection requires an exaggeration of the size of features in order to maintain the scale set.
