Air allows the visualization and analysis of the thermals and
transitions that you performed during your flight. For a good visualization use
de 3D viewer and press the button
to see the thermals.
You can make a detailed analysis of the variables that define your thermals and transitions going to the Thermals and transitions window. To open it, select Thermals and transitions at the context menu of that flight (right click on it). In this window you can find the next information:
•Icon: Graphic representation of the element type (thermal or transition) for its fast identification.
•Type: Thermal or transition. This clasification is made by an algorithm that, basically, separates the climbing stages from the descending ones. When calculating this statistic, some errors may happen. We recommend verifying, with numeric and graphic data (3D viewer), the accuracy of this classification.
•Mean vario: Shows the mean vertical speed in this section. A negative value indicates a loss of altitude while a positive one indicates a climb.
•Number of turns: It only apperars with the thermals, when you are usually drawing circles.
•Glide ratio (linear): This value indicates the covered distance, with the actual descending angle, to go one meter down. Therefore, a high glide ratio value means a light descent while a small one indicates that you plummet.
•Duration: Time between the start and the end of the section (thermal or transition).
•Projected distance: Distance projected to a flat ground, that is not counting with altitude variations. Therefore, a completely vertical climb would have Projected distance = 0.
•Mean speed: Arithmetic mean of the speeds of that stage.
•Maximum height difference: Substracts the lower point of that stage to the higher one.
•Track bearing: Mean bearing in that stage.
•Thermal radium average: The radium that would have a circle that was a mean of all the turns made in that thermal.
•Drift direction: Orientation where you have been moved during the thermal.
•Drift speed: Velocity with wich you have been moved away from the vertical line when making that thermal.
•Drift angle: Detected inclination in that thermal. A 0 value would indicate a completely vertical climb. If this angle rises, the ascention is smoother.
•Max. Vario: Maximum climbing vertical speed.
•Min. Vario: Maximum descending vertical speed.
•Number of right turns: Right turns during this thermal.
•Number of left turns: Left turns during this thermal.
