XM weather in Europe

Availability of weather info in the cockpit should be a must.

It is a pitty that European goverments have a commercial approach to this instead of the safety approach that the US government has.
The US government publishes weather info for FREE to companies like XM Sattellite weather that distribute it to airplane cockpits.

I recently had a long conversation with a top executive at XM. I asked him whether they would be offering cockpit weather info for Europe, and my conclusion was that it does not make business sense to them due to the prices that european weather agencies charge for the info.

Avidyne’s solution

Recently, Avidyne has started selling cockpit weather (through its new MLX770) via the Iridium Satellite Network to those having Avidyne’s Entegra and EX500/EX5000-series multi-function displays.

I heard that there is quite a delay from the moment information is published to the moment it is available in the cockpit. To some, that would render the information obsolete. But… How true is that?

I would like to know, first hand, if that is the case.
So far, though, I have not had the chance to fly an airplane featuring such a solution. Have you?

If so, please comment so all of us have a better opinion about this system.

  1. I am flying with the MLX770 / EX500. The delay of radar pictures can be neglected, however keep in mind that there are new pictures only every 15 minutes available from the national weather services. Metars and Tafs come much more frequently.
    That is good for strategic decisions, but for realtime infos I am using additionally the TWX670 3rd generation Stormscope which gives me coloured contours like radar, even in the range from 0 to 20NM and up to 200NM.

  2. Very interesting topic indeed. I don’t think that politics allow another position of the weather data providers than the “commercial approach”.

    For my curiosity: Do you know how the TWX670 can produce this: “up to 1024 strikes are displayed for up to 3 minutes. Each transmitted strike includes range, bearing, and weight (color)”? How specifically can they differentiate between weight and range? I thought intensity has to be interpreted as closeness, as e.g. with passive collision avoidance.
