We just finished our NC-UT migration using our Android tab. I always use the runway extensions as another means of verifying that what I'm doing is what I'm supposed to be doing....
The extensions are shown with red/white shading, which to be honest I thought related to the left/right pattern for that particular runway, but I found that isn't the case. The runway left/right pattern is shown with a green directional leg extending from the red/white extension marking. IMHO, the green marking is much harder to see than the red/white shading.
Two easy to find examples are CNY and HSD.
Would it be possible to use the red/white shading for pattern markings as well as the green directional leg?
