I fly a paramotor using winds aloft to do triangles at different altitudes with 3 tailwind legs. The following video shows ideal conditions

My biggest triangle so far is 313 km triangle

Below is a mock up using iframes to show winds at 4 different altitudes.

Is anyone interested in working on this to develop a way to synchronise these views to browse forward and back through time (and ideally pan to different locations)?

Thanks in advance for any assistance,
Peter Evans

I'm looking at the airogram and I notice these black holes. What are they?

I've looked at the temperature in the map at the relevant height and time and nothing is shown.

Hi @rittels

This is a fantastic tool. Thanks for your excellent work.

I am now using this to optimise FAI triangles for maximum length using Winds aloft predictions ... my longest foot launched PPG FAI triangle is 313 km.

Can I suggest you output the GPX file as a GPX ROUTE rather than a GPX TRACK or allow the user to select this as an option. A GPX ROUTE can be imported into most flight instruments to be used during the flight ... I use LK8000. GPX files can encode 3 types of data...

• wptType are individual WAYPOINTS
• rteType are a ordered set of waypoints (lat and long) generally used to represent a planned ROUTE
• trkType are a ordered set of waypoints (lat, long and time) generally used to represent an achieved TRACK

The only changes need to convert a GPX TRACK to a GPX ROUTE are:

• replace "trkpt" by "rtept"
• replace "trk" by "rte"
• remove
• remove

I would be VERY HAPPY to provide you with detailed feedback on any of your developments.

Once again, thanks for your excellent work.

@dzuremar Thanks for your quick and informative reply. The airgram is important to me as a fly a foot launched powered paraglider and use winds at different altitudes to extend my range. Often on the east coast of Australia in summer there is a lower eastly with an upper westerly. My main fuel tank is 14 litres and while I can use an aux fuel tank (in Australia) it significantly increases the weight I have to carry and the risks.
Thanks for your EXCELLENT weather visualisation tool.

@mhaberler
I am REALLY interested in this. I fly a paramotor and am currently working on flying large FAI triangles (shortest side has to be at least 28% of the total triangle). I use different direction winds at different heights to improve my speed and thus distance I can do using the 22 litres of fuel I carry.

Current favourite site is take off at Yass (Australia) in remnants of the easterly sea breese (up to 1500AGL) and fly NE then NW and then climb into the upper synoptic westerly (up to 8500 where there is controlled airspace) to do a W leg to return to Yass. Longest flight so far is 313km at average speed of 74kph.

Are you a JS developer? I have a developer background.

I'd be REALLY keen to incrementally develop a plugin. e.g. for a given location find times when there is a wind direction difference of more than 150 degrees in wind layers from surface to 10000 feet. And then add functionality

MANY people would be interested (aviation, balloons), nothing similar is available and the excellent people at Windy provide access to the best datasets.

Is anyone else interested in this? I'm happy to provide use cases if ant developer is interested in a project.

Hello,
First thanks for your EXCELLENT site!

I fly a paramotor to a max height of 10000 feet and would like to only see the lower part of the airogram to 700h (Surface to 10000 feet). Is this possible?

Thanks in advance,
Peter Evans

I updated Chrome and reset it to factor original settings... but still showed as black.

I did a complete uninstall and then clean install and the airgram is now displayed correctly.

Thanks for your help

It displays correctly in Internet Explorer Microsoft Edge, and Firefox.

@ivo, Thanks for your reply.
I just looked at the airgram for several locations. It no longer displays the stripes but it always displays a black box where the airgram should be (see image). I'm using Chrome Version 61.0.3163.100 (Official Build) (64-bit) with Windows 10

I tested it in IE and the airgram is displayed correctly.

Hello,

First, thanks for your excellent app and visualisations.

Unfortunately the Airgram no longer displays (all black or has stripes all over it) or takes a long time in Google Chrome. Does anyone have any suggestions for fixing this?

Thanks in anticipation,
Peter Evans
