Point Inspector
Special Chart Markers
A quick tap near any chart point will select the chart point. You will then
see a flag icon in the toolbar that you can press to mark the point.
A longer hold will bring up an point inspector that displays the data
behind each point. Drag your finger to examine different points. Tap
quickly anywhere on the chart to dismiss the inspector.
There are several important marks that control how the flight is analyzed
and shared:
Flight Start and Flight End
These round markers indicate when then flight began and when it ended.
The flight duration is calculated from these points, and the chart page
will be sized to show the entire flight properly. The app tries to set these
points automatically, but sometimes you have to set them yourself.
Data Start and Data End
Sometimes you may not want to include all of the data in your
spreadsheet. These two lines mark the start and the end of the data that
you want to include in spreadsheets.

Acceleration Data
Data End
Not every mode records acceleration data. See the
Settings page for more information.
Acceleration and Direction
Acceleration data is collected using a highly sensitive,
3-axis accelerometer. This means that you can sense
the direction that acceleration occurs, and view the
acceleration that occurs in the X, Y, and Z directions. The
positive directions for each axis are shown in the diagram
Flight End
below.
Total Acceleration
Total acceleration is the non-directional combined
magnitude of acceleration, calculated using this formula:
