If you can't get through your CPL test without a VNC, you're deep in it!
Fair call, the larger scale & more info on the vnc is nice esp when at 500' agl, found it a little more challenging when the ground features in veiw couldn't be related to the wac because they weren't on there
the 'what the' moment came when the instructor pulled out his vnc to find a derversion & then kept a close eye on his hand held gps
