Après Sky

You’ve arrived at a new airport. The flight has been a pleasure and you definitely want to celebrate it with your flying buddies.

Where to go for a drink?

If you’re lucky you’ll find welcoming local pilots that will tell you where to go. But unfortunately that’s not always the case…

Or say you’re planning a trip to a distant location and want to plan the car rental or hotel in advance.

Which one is closer to the airport?

You just got to a city famous for its beautiful venues (like Barcelona)

What to visit?

Till today, these were not easy to answer questions.

Now, you’ll also be able to visualize information about: Continue reading “Après Sky” »

We’re excited with Flight condition Statistics

By now, you should know we’ve been working on metar statistics (there are 3 other posts, or so)

The fact  is that lots of information can be gathered from METARs through time (temperature, wind, dew point and cloud base profiles…)
At one point, we were even asked to evaluate forecast reliability (through METAR-TAF difference)

But for now, we elected to keep it simple and monitor how much an aiport is in VFR conditions.

My initial intention was for the stranger pilot to be able to get an idea of how ‘bad’ an airport could be in a particular month, or time of day.
So we started saving flight condition statistics back on Dec the 1st, 2008. So far, we’ve stored over 30 Million flight condition reports !!!

Well, let me tell you that we’ve found database and server load challenges… But we’ve kept up.

And recenlty, we’ve started to analyze whether all of that storage made any sense. Let me show you…

Below we have a chart for LELL flight condition statistics from Dec’08 to Jun’09:

Here you can easily see what a nice airport LELL (Sabadell in Spain) is to fly to in VFR conditions:
The percentage represents the number of VFR, MVFR, IFR or LIFR METAR reports (according to this flight conditions definition)
On the horizontal axis you have each month (with time of day inside). So we can see that back in February, the morning and night METAR reports had less VFR conditions than those around noon. You can also see that the closer you get to the summer months, the more VFR conditions existing at LELL.

Let’s see what this looks like at the famous low visibility LIMC (Milano Malpensa in Italy):

What a difference!

Here, we can see that back in the December-January period on average only about 40% of the METARs where reporting VFR conditions.
Here too, the closer we get to summer time, the better it gets.

What we see seems now worth the time and effort we put into gathering statistics.

We’re not quite ready to share this sort of reports with the general public, but have started working on it.

As usual, please let us know how you like it.
