[In another thread discussing trip planning and fuel consumption allowances, the topic of the] Garmin Bluechart Mobile app [was introduced and has now been move to this separate discussion--jimh].

Does that Garmin Bluechart Mobile app do fuel estimation of best combination of two rates to cover a certain distance with a certain fuel reserve? I am not familiar with it. Could you explain how it would help in fuel planning?

I already have detailed charts and trip planning software, so I don't need any other applications for that. I developed the algorithms to help myself (and perhaps others) understand how to cover a distance that can't be done at a planing speed.

The Garmin app allows for route planning with simple fuel consumption awareness. The route is built by touching, sequentially, points on the chart, similar to a modern chartplotter that uses either a cursor control device or touching points on a touch screen. The app "connects the dots" you put on the chart.

Using user inputs of speed, fuel consumption rate and fuel capacity for planning a route, the application displays the route as it is being built in a color variation beginning with green (indicating full fuel capacity) at the beginning of the route that gradually changes towards red (indicating fuel capacity exhausted) as the route grows in length. So one can quickly get a visual that a route at a predetermined speed and fuel consumption rate is getting into the risky zone regarding remaining fuel capacity. It also displays how much fuel is expected to be used and remaining.

Now if one stops the first fast, but less efficient route segment when the color of the end of the route turns to orange, for example, one can then start a second route using the new slower speed, lower fuel consumption rate and remaining fuel parameters. Again, one can see how far that route can be stretched before the fuel capacity is exhausted quite quickly by the observing the color change from green to red.

I think this functionality may work even if you don't buy a $30 chart. The app is free.

The Garmin Bluechart mobile app sounds like it has nicely integrated fuel consumption into the route planning. Thanks for the details on its capabilities. I was not aware of it before you mentioned it.

Here is a link to a thorough review and summary of the rather recently released Garmin Bluechart mobile app:

It appears to be an iOS application. I don't have any iOS devices except a rather old iPhone, and its screen is too small for real use with this application. Maybe this is the must-have application that will drive boaters to buy a new iPad.

The fuel consumption estimating is not new functionality in the Garmin world. It was previously available on Garmin chartplotters when route planning. The difference when route planning on an iOS machine versus the chartplotter is that the iOS machine will display the route with the varying color graphic while in the planning mode.

Unfortunately, there is no indication that an Android version of this App is coming. It seems odd that Garmin would not make an Android version given that there are far more new Android machines being born everyday than iOS machines.
