As an IFR pilot, I would like to see data on cloud tops.
It is 100% certain this data exists, from satellite imagery, but I have never found anything which is reasonably real time (less than 1hr old, say) and with usable resolution.
I have requested that the cloud tops be put back onto the 215/415 to give more granular understanding. But the cloud tops are available on the Europe SigWx charts as well juts on a wider scale.
I am expecting a response on my request prior to the next Met Office WG meeting and if as is believed it is simple enough to change we should see the data appearing again soon.
