Interesting, I’ve got a theory, but I’m a Garmin Pilot guy, not Foreflight. VP590 doesn’t exist in GP.
Some Visual waypoints are assigned a VP*** name on the TAC or sectional charts and some aren’t. In the example below, SLAC/Linear accelerator is assigned VPSLA. I can enter VPSLA into my 430 and also Garmin Pilot. However, Stanford Stadium, which is also marked with a flag thingie, does not have a VP name assigned. Can’t enter it into either my 430 or GP. My theory is that Foreflight has assigned the VPnumber name to the visual waypoints like Stanford Stadium which don’t already have a name. Since I don’t have Foreflight, I can’t test the theory. Maybe one of you Foreflight users can check and report back?
