Latest news, Aug 2, 2026: I've made some improvements to how BumpySkies treats airport elevations, as well as the rate at which planes are forecast to change altitude when taking off or landing. More about it in the next newsletter. Until then, if anything seems off, please report an issue!
FLE657, YHZ to YYZ: no forecast yet
It's too early to give you a forecast. I don't yet know the flight plan for this leg of FLE657, so I can't give you an accurate forecast right now. Come check again closer to departure time. (Note that sometimes I don't know the flight plan until minutes before boarding!)
