when downloading the file welt2000.txt.new.

The looping is happening every

Download can't be stopped, need to use taskmanager to terminate application.

KFLog uses two different items for a control zone. These items should be replaced by one common item because the airspace file format description do not differ between different control zones.

currently no license terms are available within the range of the user interface.

There should be added support for configuration, download, parsing and loading of openAIP airfield data.

see screenshot:

(we should also supply complete meta data for the package (license/update information).

The date of a flight is not set in the flight data points of a read IGC flight.

KFLog should be ported to Qt5 to be useable in the future. The effort is not so much. Cumulus can be used as an example for that.

When changing the selection Flight - Show Flight Data from Altitude to something else nothing changes in the visualization of the flight path.

I looks very much like the current visualization only supports Altitude, indication for that is:
changing the value of Flight Path width for the altitude in Settings - Kflog Setup... Flight Display the flight path is shown with the selected with - regardless the selection of Flight - Show Flight Data.

Other Flight Path Width values are not used, the colors in the settings dialogs are not used at all. The colors used for the path are somewhat depending on the heigth (you can see that the color changes after a thermal), but there is no legent (color - heigth) shown anywhere.

without doing any changes.

I am not very familiar with Qt and mingw but I think we are facing an overwritten stack.
The crash happens after the Settings Dialog has been close at the end of the reload (progress bar is close to 100%).

Any idea what I should look for?

According to IGC Code Sportive Section 3 / Class D, 4.2 it is not necessary to specify the airfield you are starting and landing during a task.

Currently KFLog requires Startfield / Startpoint / Taskpoint 1...n / Endpoint / Endfield.

The first and the last are not necessary for an IGC Badge or Record Flight.

This should be fixed in the Task Editor and the Task-Validation routines.

when selecting the Homesite in Settings - KFLog Setup - Identity, the list of shown airfields is filtered according the Airfields specifications in Airfields Dialog.

This looks like a chicken-egg-problem.

At this point I would expect the unfiltered Airfields list - but that is a minor enhancement

At the moment the task editor opens a message box with hints to the selected task type, if the task editor is opened. The popup message boxes can not be switched off even if the related checkbox is checked.

The lower end of a flag map icon (e.g. waypoint, hotspot) points not directly to the related position at the map. That is irritating for the user.

The QNH handling of a flight must be improved.

1. Do not ask during read in of a flight for the QNH. That prevents batch jobs. Set always the QNH to 1013 hPa.
2. The set QHN should not be stored in every read flight point. That makes no sense. Put it in the statistics of a flight.
3. Show the set QNH in the airspace item of a flight in the object tree. Here is the right place, if the user must adapt it due to airspace violations.
4. Add the duration of an airspace violation to the text.
5. Add a mouse popup menu to the airspace item in the object tree for QNH setting and airspace violation check.
6. Move all QNH actions from the flight loader into the flight class because every flight can have its own QNH.

currently the reset scope of the Default button is global.
If I am working on the forrest element and hit the default button the settings of all other map elements (Airspace A...Trail) are also resetted to the programs defaults.

The default button should only reset the current map element back to default.

Place 1:
Settings - KFLog Setup... - Waypoint Catalog - File Open Dialog - supported WC types:

Place 2:
Settings - Show Waypoint Catalog - File Open Dialog, Supported WC types:

There should be only one source where we can open the waypoint catalog files.

we should show the number and unit of the single threshold instead of the abstract name Threshold #1, Threshold#2...

It should be possible to navigate to a waypoint list entry via a search function in the task editor.

Currently KFLog uses two different Helpsystems,

1. Help -> What's this is only working over the map area, other dialogs are not using this helpsystem
2. Windows --> Show Help Window. This Windows is only working for the Evaluation Window.

If the Evaluation is part of the KFLog Window the Help Window seems to be a part of the Evaluation Windows (additional Tab in this Window). If the Evaluation Window is used as a separate dialog (Window with Windows Manager decoration) the help Windows stays inside the KFLog application and is no longer a TAB of Evaluation.

Following enhancements are proposed:

1. We should use none unique mechanism to implement online help
2. All KFLog-dialogs/windows should implement their help into this mechanism.

An up-to-date KFLog user guide is currently not available. There exists only an old German user guide from release 3.x, which is not more up-to-date. At first an English user guide should be setup.

The KFLog flight recorder plugins are currently not yet ported to Windows.

KFLog crashes, if the main window is resized and a message box is opened to ask the user for data downloads. That was observed on a 64bit XUbuntu OS in a virtual box from Oracle. Analysing that, I found out the following facts:

1. Main window is resized by the user
2. That generates a resize event by Qt and implies a redraw of the KFLog map
3. During the redraw of the map is detected, that map data are missing.
4. That implies to ask the user to allow the downloads of the missing data in a Qt message box
5. The Qt message box goes into the GUI event loop and waits for an answer from the user. The resize event call is not yet finished at this moment.
6. The user generates further resize events, which will overrun the previous resize event.
7. If the user answers to the message box and the first resize event is finished, the application is crashing.

I could fix that, by introducing a single shot timer in the resize event call, so that the resize event is immediately finished and the further processing is done in the generated timer event.

QTimer::singleShot(0, this, SLOT(slotRedrawMap()));

That has prevented further crashes on a 64bit XUbuntu OS in a virtual box from Oracle.

It should be possible to download and use openAIP airspace files in KFLog

after the Airfield Option was selected and used once it is no longer possible to switch the radius to the Homesite - it stays on the formerly selected Airfiled

The setting of the home site in setup identity should be enhanced, that the home site can be selected from the loaded airfield list too.

IGC has define a shell environment allowing a common user interface to load vendor-specific DLLs providing the functionality to download and validate flights from the flight data recorders.

Check whether KFLog can use these DLLs for communication with the flight recorder.

For technical details see http://www.fai.org/igc-documents - Flight Recorders -

at the moment this information has to be collected manually.

• zooming is very slow at the moment
• every wheel-click will increase/decrease the zoom/level by one scale.
• +10 zoom events can easily happen with one time turning the wheel

very bad user experience caused by slow performance!
(maybe one should peek events from the event queue and do only one zoom operation instead of 10).

• when mouse wheel based zooming is handeled the current mouse location on the map should also be considered to move the map center towards the mouse position.

even though it exists in the airfield (?) catalog.

You can use it to create a task, but it is not shown with an airfield symbol on the map.

Don't ask me how I get to here. I don't know it.
And it is even hard to get back to germany:-)

It should be possible to setup an automatic update of airfield and airspace data, which are downloadable from the internet. The automatic update should be able to switch on/off by the user. Furthermore the user should be able to define an update period in days.

The drawing of waypoint labels on the map should be configurable by the user.

Prevent the automatic closing of KFLog settings dialog, if the return key is pressed. That is a feature of a QtDialog but not useful here.

we have the loop again.

download manager does download welt2000.txt to kflog/mapdata/airfields/wetl2000.txt.new

some later:

welt2000.cpp does following check:

get last writetime on kflog/mapdata/airfields/wetl2000.txt
if the file was alread downloaded today it will load the file - no further downloads.
if the timestamp of the file is older than today, it will trigger the download.

This check is done to avoid unnecessary downloads in the case kflog is started mutliple times.
But the check makes no sense if the file is already downloaded before the check is performed.

if kflog/mapdata/airfields/wetl2000.txt does not exist welt2000.cpp will trigger the download manager, who will again download welt2000.txt.new.

No routine is currently renaming (or copying) welt2000.txt.new to welt2000.txt.

currently we can't change the transparency (opaqueness) on forrest objects (the controls are disabled).

All map elements which cover areas should allow the selection of opaqueness.

The elevation label in the statusbar is not updated during flight animation. Furthermore it considers not the user's set unit.

Scale Limits:

1. Changing the Lower Limit seems not to have any influence on zooming.
2. Changing the Upper Limit seems to have no effect on the maximum zoom, but the smaller you choose the number, the smaller you can zoom (looks like working as lower limit)

What units are we talking about (kilometers / miles / pixels)???
The units we are working on should be shown.

The former Airspace Foxtrott is replaced by Airspace RMZ in Germany at 11.12.2014. The application should be able to handle that.

The defined action shortcuts in the temporary popup menus e.g. of map and object browser makes no sense because they can overlap with the global menu shortcuts. Therefore action shortcuts should only be used in the global tool menus.

when planing a task we have to specify takeoff Start and End location.
This three points will be identical with airfields in most cases.

They have to be part of the waypoint catalog otherwise we can't select them into a task.
On the map we will then show airfields and waypoints which are airfields in order to work with them.

this leads into double information on the map in order to work properly with tasks.

The example shows Musbach with the gilder symbol (originated in airfields) and a black rectangle (originated from the waypoint catalog).

My suggestion would be, that we should have something like a merged waypoint catalog which will contain the airfields and the elements from the waypoint catalog selected with a filter.

if I have a look at my home area, I recognize that the forrest zones (the two dark green doted areas) visible on the KFLog map do not really represent what is existing:

compare it with google maps

is there any possibility to have a look on a map generated with other software and based on the same data?

by the way:
I would prefer a different default setting for forrest - something looking like this:

with test IGC File: KFLog/testdata/391V7331.igc.

crash happens only on linux (windows has no opengl port).

The user should be able to select different vertical and horizontal speed units in the configuration of KFLog. Furthermore all unit related values (distance, altitude, speed) should be displayed in the user's selected unit.

Menu item it is always empty.
Under menu item Settings we have a lot of entries which create new dialogs/windows. most of the dialogs do not deal very much with Settings.

We should either move them to the Windows Menu Item - or delete the Windows Menu Item

Provide GUI surface translations for other languages. The KFLog default language is English. As next a German translation should be provided. Other languages are also possible, if we get the support for that. Qt uses the tr macro for strings to be translated. The KFLog code uses this macro already.

We should change in the class WaypointCatalog the usage of the xml DOM model to a xml stream reader model for reading/writing of KFLog XML waypoint files. The DOM model uses a lot of allocated memory and can therefore cause problems, if the waypoint files are very big.

Maybe the waypoint XML syntax structure should also be overworked?
