I'd be interested for someone to make that same flight or test and flip from Sectional to Vector to see if there is a discrepancy between modes. Vector Mode is rendering airports, towers, airspaces precisely based on the FAA's database.
If someone will report back their findings, I've personally seen this on many sectional charts... My waypoint or position over the sectional being slight off, up to a mile in cases. That's why I use Vector Mode more around critical airspaces. I hope this helps.
Hi Shane,
Well I tried your experiment today (switching between Sectional mode and Vector mode while approaching the class-D airspace perimeter.)
In fact I also had iFly iPad open and had it in Vector mode while in Sectional mode on the720.
Both the perimeter shown in vector mode and the perimeter shown in sectional mode are (according to ATC and the distance to airport readout on iFly) at about 1.0 to 0.7 miles INSIDE the 5 nautical mile radius.
In short, whether I have Sectional or Vector view on if I trust the lines shown on the moving map I could be about a mile into their airspace and not know it.
At least I can make that statment for the current Klamath sectional area map and the airport MFR.
