Digital Sectional is designed to work similarly to how you fly. In VFR, depending on the distance of your flight, you start with either a WAC or VFR Sectional chart. Then you might want view a TAC chart when in a metro area. If you’re a helicopter pilot, you might want the helicopter chart available as well.
Using a unique layered approach, Digital Sectional can actually layer all of these types of charts together and on top of a base map. Each layer can be turned on or off at your discretion and no layer (except the base map) has to actually be selected. The layering is in this order:
- Terrain Awareness
- High IFR
- Low IFR
- Helicopter Charts
- Terminal Area Charts
- VFR Sectionals
- World Area Charts
- Base map
Digital Sectional has a unique way of using IFR charts… You can optionally choose to overlay the IFR charts transparently onto any of the layers below it. This is optional and can be adjusted in the Layers Option view. For example, here’s an screen shot of a low IFR chart overlaid onto a VFR Sectional.
Digital Sectional ships with a simple base map for the entire world. It is intended to be a simple reference and to keep the app download size small, only has native support for a few zoom levels. After that it gets a little fuzzy! However, you can download one of the many fantastic basemaps that Mapbox (www.mapbox.com) provides from within the app. These downloads are free and you can download as many as you want and change them at any time in the layers list.
