Re: BVI chart/nav app

If you use the Imray-Iolare charts, note that they are not only not to NGA standards, but they are on a different datum than the US charts and your chartplotter, which is undoubtedly on WGS84. Read the fine print on the chart if you want to be precise, although there is only a very slight correction if you want to transfer a waypoint from the chart to your GPS.
