New app to analyze your flights !!

[Mar M]

Hello,

Just wanted to let you know that we developed an android app able to analyze your igc files, called xc analytics: https://xcanalytics.fr/en/
In a few words, it's statistics applied to cross country flying.

It gives you access to more than 60 statistics and 40 charts relative to your flights, an original identification of 4 different phases (prospecting, climbing, floating and gliding), and the possibility to compare your flights with others.

It is brand new, and there are many updates to come, some of them based on the feedback the pilots give us.
Let me know what you think !

Cheers,

Martin

My first impressions: nice interface, lots of data and great statistics (including weather statistics, like wind direction etc.! - and mean distance between lifts!), funny comments. I like it gives both UTC and local launch/landing times. Nice, very clean map with strong road lines and water bodies. A little glitch noticed: in the Information section the app consistently describes the flights type as 'mountain" while they were actually flown over flat lands. I also get the 'mean glide ratio' as '18:54' - I believe we are rather used to the form 'one to something' All in all: IMHO, the best app for smartphones so far and worth spending the symbolic few $$.

Many thanks for your kind words Tom BravoMike, and your interesting feedback !

It looks like we did not train the algorithm enough over US landscape. We will improve that. By the way, if that is ok with you, we would be glad to get one (or more) of the igc files that showed "mountain" where it should have been "flat lands". You can send it at

We will amend the number for the glide ratio accordingly. Look out for future updates !

Do you fly a brick?
An L/D of 18:54 means you're losing three feet/meters per one foot/meter of horizontal movement.
Maybe the intention was to indicate that the glide ratio was between 1:18 and 1:54?

I meant 18:1 to 54:1

I would like to have a Win 10 version.

This number is specific to a certain type of phase detected in the app, "gliding". It is different from "floating" phases. When you look at the glide ratio of those two types of phases combined, it is actually much higher.

Hello Tom,

We plan to make one. As you can imagine, it will take some time to develop it, as we have to entirely code the charts again. Pilots' interest will definitely help !

Of the phases - "prospecting, climbing, floating and gliding", only climbing and gliding are familiar to me for sailplane flight analysis. Are floating and prospecting hang glider and paraglider terms? I wouldn't find them useful.

Those terms apply to the 3 disciplines, and yes, they are new in flight analysis !

In a few words:
- when you look for a thermal/wave, or lose it to find it again, it is "prospecting".
- when you fly a portion of your flight better than you usually glide, it is "floating".

This can be very useful to help pilots progress during debriefing. For example, it is actually used by instructors in France to discuss the flight a posteriori with their students, so they can better understand what can be improved.

To me, 'floating' sounds like what I'd call 'running an energy line'
which can be anything from following a blue street to playing 'join the
dots' with haze caps or smallish cu, both being generally more useful if
your track is more or less parallel to the local wind direction.

Your definition of prospecting is subjective and can only be approximately inferred without knowing the pilot's mindset at the time so I would not find it helpful for an analysis program to attempt to identify it objectively.

You could replace "floating" with analysis based on "netto rising" phases.

"Floating" and "Prospecting" make perfect sense to me.

Me too. The app sounds good, but I have little interest in using it on a tiny screen.

That's great news because this is exactly the kind of IGC viewer that I have been looking for.

Is it possible to download on my iPad ? It keeps referring me to th google store and I can’t get at it from there.

Is the purpose to make something better than SeeYou, to make something cheaper than SeeYou, or something different?

Hello pilots !
Sorry for the late answer, I was away for work. Here is what I can say about your questions / comments:

> Your definition of prospecting is subjective and can only be approximately

Well, at least it is not subjective as long as you agree with it ! You don't really need to know the pilot's mindset to define the phases, as much as, for example, netto rising is polar dependent.


> "Floating" and "Prospecting" make perfect sense to me.

Good to hear Nelson !!

The app is compatible with any tablet for your information. If you are looking for a desktop / Windows version, we plan to make one (before an iOS version), but it really depends on the interest of pilots for the app.

Brilliant, thanks Tom !

Dennis, sorry, but no iOS version for the moment (as said above). The Apple store is the most demanding and restrictive platform regarding apps. As soon as the desktop version is available, I will let you know.

All of the above ? ;)
