meteorological capability

Postby marpdiaz » 12 Jan 2014, 13:19

Cell phone coverage is getting better. In the region I fly more often I get signal about 40% to 60% of the time. On the other hand, most meteo images that are useful in flight are small in size (~10⁴ bytes) and have local coverage (few hundred miles at most).

Here is one example of an age coded lightning map that allow us to see the movement of convective systems. It is updated in 2 min intervals at the website:

A "simple" way to implement meteorological capabilities is leave to the user the input of his/her favorite URL pointing to a meteo image (precip, lightning, cloud tops, whatever). Associated with it, the user may define a linear georef (2 points, 2 coordinates) for such images and a refresh (download attempt) time interval.
A flag can warn the user that last download attempt was unsuccessful and the map is getting old - but still better than those from preflight weather briefing. Availability of directly downloadable images may be an issue.

A fifth FIF screen with a recently dowloaded meteo image can make the difference to divert wisely and get us out of trouble.

clear skies,

I am experimenting with using an app called "Aircraft Radar" I think it is only UK but looks and feels like a big aircraft weather radar.
Uses mobile data for the Met. Great if added within FIF maybe as a 5th screen or a quick show on the map.

My experience with the weather radar sites is that the mountains false the indication. The problem is that the false negative indications causes trouble.
For exemple, a destination airport can be visualized on the radar site complete free of rain, but in reality its submerged with precipitations, because on this area, the radar detects only over 6000ft.
An other question is the wind and the cloud covering. This is normally very accurate.
