"My experience, and it seems it is the same as some of the other posters on this thread, is that the common conditions in which large OAT rises have been seen are:
- tropics
- over water
- nearby or recent convective activity
- flying in stratform cloud (appears as widespread speckled green wx radar returns)"
Bleve,
Thanks for the information. So you don't think I haven't flown much around the world, I can state I have flown across every line of longitude, as far north as Fairbanks and as far south as Perth. I just have never met the conditions you described after over 30 years of flying (US Navy, TWA, ATA, etc). I will say I have never operated in the South Atlantic area.
One learns something new every day in this business.
I do hope they find the "boxes" so we have a clearer picture and less conjecture.
