Understanding the Statistics report

SeeYou features comprehensive statistics for the active flight.

Select View > Statistics from the main menu or use the  icon from the Flight toolbar.

There are four pages for the statistics report:

• Flight – gives you the stats for the flight from take off to landing.
• Task – gives you the stats for the declared task.
• Selection – gives you the stats for the selection you have made. This page is empty if no selection is  defined.
• Phases – gives you a list of all phases of your flight which you can sort on any available value. 

Double clicking in various sections of the Statistics report opens different windows:

• Flight properties in the General section and Flight statistics section.
• Flight properties – Task in the Declared task section and Task page.
• Selection dialog in the Selection page. 

Example of the statistics window with bars and wind vectors:

General information

This section gives you an info on:

• the pilot,
• the glider,
• take off and landing times,
• the duration of flight,
• Sunrise and Sunset times for take-off position and landing position respectively.

Declared taskThis section gives you this information about the task: Valid or invalid declaration (in the example, the task was entered after the flight making the task declaration NOT VALID).

• Date and time of the creation of task declaration,
• Take off and landing points,
• General statistics for the flown task is entered in columns representing: name of the point, Latitude/Longitudes, leg distance, altitude at the turning point, time at the turning point, leg time, achieved speed for the leg (start and finish times are interpolated to the nearest second), average wind for the leg, average wind component on the leg.

Below this section there is a section about the total result for the task:

• The information on how  turnpoints were reached. If a turnpoint was missed, but the distance to the  point was less than Near enough distance, set in the Options window, then the point will be calculated as reached, but this line will have an error message telling you that sector was not reached at that turnpoint,
• distance of the task,
• duration of the flight on task,
• speed achieved on task,
• if the task is a triangle, triangle speed is displayed last.

Double click in this section will open Flight properties in the Task page.

Flight, task, leg or selection statistics

The Flight statistics section (in the Flight page of Statistics) contains the same structure of data as the Task and Selection pages.

The data is structured into the:

• General section,
• Circling table,
• Straight flight table,
• Bar graphs and Histograms.

General section for the specified section (this is only section not included in Flight statistics of the Flight page) contains information about:

• flown distance on the task or leg,
• start and finish time of the section,
• duration,
• achieved speed for this section.

XC speed is the speed that would have been achieved if the pilot had climbed back to the start altitude with the average lift. If the finish altitude is lower than the start altitude, then XC speed is lower than  plain speed because time to climb back to the start altitude needs to be added to the time spent on task. If finish altitude is higher than the start altitude, then the time spent to climb above the start altitude is subtracted, then XC speed is higher than speed. Start and finish are always referred to the start and finish of the portion of the flight to which the statistics you are looking at at the moment is referring to.

Maximum altitude gained

This row lists the altitude gained according to FAI badge and world record rules. Details on low and high  point are listed as well.

Example for altitude gain line: 

Circling table

The data is divided into rows for:

• Total circling,
• Circling to the left,
• Circling to the right,
• Tries (<´min. time´ is entered in the Options dialog.

The columns represent:

• Time spent in the specified form of circling (percents in the brackets)
• Average vertical speed achieved,
• Altitude gained,
• Altitude lost – this is all the meters lost while circling.

Note that average Vario is calculated as (Altitude gained + altitude lost)  / (Time spent).
Example for circling statistics:

Straight table with the values for:

• Time spent flying straight,
• Distance done is the distance covered including all turns and deviations (sum of the distances between fixes),
• Altitude gained while flying straight,
• Altitude lost while flying straight,
• Average GroundSpeed (Distance done divided by the time spent),
• Average Indicated Airspeed (IAS) to see how fast the pilot was pushing the glider,
• Mean L/D is the average rate of descent or gained if negative (Distance done divided by the sum of altitude gained and lost).

Example of statistics for the straight part of the flight:

Bar graphs and Histograms represent the respective data divided into small portions ranges of values  (adjustable through Options dialog). The value representing the middle value of the range:

• Wind histogram presents the distribution of the wind in different altitude layers. The lines represent: Wind vectors. Longer arrow represents stronger wind , Altitude layer, Time spent in the altitude layer, Average wind in the altitude layer.
• Vario histogram  presents the distribution of thermal strength for the specified part of  flight. The lines represent: Red bar represents time spent in the vario range, Blue bar represents the altitude gained (or lost), Strength of thermal, Time spent in that strength of thermal, Altitude gained climbing with that climb rate.
• Altitude histogram presents the distribution of the strength of thermal in dependence  to the height above sea level. The lines represent: Red bar represents time spent in the altitude layer,  Blue bar represents the average thermal in the layer, Altitude layer (the number representing the mid value of the layer), Time spent circling in this layer, Average Vario in this layer.
• Speed histogram presents the distribution of the speeds used during flight. The lines  represent the: Red bar represents time spent in a range of speeds, Blue bar represents the distance covered in a range of speeds, Green bar represents the altitude lost in a range of speeds, Mid value of the speed range, Time spent flying straight with the respective speeds, Distance covered flying with the speed inside that range, Altitude lost (or gained if positive) flying with the speeds of this range.

Example of the Bars and Histograms:

Flight Phase statistics

On this page you can explore flight parameter values for each flight phase by ordering them on any column.

Sorting flight phases

By clicking on header of any column the data is sorted on this column. If values in the primary sorting

colum are repeated, then previous selection is used to determine how data is sorted within the repeated

value.

Example 1:

1. Sort phases on ‘Begin’ column
2. Sort phases on ‘Phase’ column 

Circling and Straight phases are separated. Phases within Circling and Straight are sorted on ascending  time. This means that in AVario column you have a chronological list of thermals used. 

Example 2:

1. Sort phases on ‘End Alt.’ column 
2. Sort phases on ‘Phase’ column 

Circling and Straight phases are again separated. Phases within Circling and Straight are sorted on  descending End Alt value.

Right click on the column section allows you to select:

• ascending sort order,
• desending sort order,
• which colums are visible. 

Using Flight phases in desktop

A great way to analyze your flight is to open a desktop with Flight phase statistics and (at least) a route

window. Double click or ‘Enter’ on a specific flight phase will move the glider symbol to the middle of that phase. 

Copying phase statistics for further evaluation

You may select any number of lines from phase statistics and copy them by Ctrl+C to clipboard. You may

paste them to Excel for example by Ctrl+V and do any further analysis you can think of there.
