aircharts.org charts not loading in Charts, Navigation and Flightplanning Help Posted April 28, 2017 Right, I've got it now. Turning on "Display PDF in browser" allows ECR to show the chart within the ECR window. I'll throw the feedback out there and I may be the only one. It's not as nice to use as LEROY although it is more visually pleasing. The chart size limitation is too small. It would be nice to have the option to open the chart directly into adobe reader or acrobat. I understand that the website allows me to download each chart individually and open them as I desire. The reason I say that it's handy to have that functionality is that we generally work more airports simultaneously than RW facilities. Switching back and forth between 2 or more airports within the same app can get comebersome. I still appreciate the work on the product.
