Yeah, but I don't understand why you'd cancel the flight instead of just reduce takeoff weight. Perhaps it just becomes uneconomic to run the flight if they can

  These planes were tested/certified for a certain temperature range. If higher temps become more common, they could potentially be re-certified with more stringent weight restrictions.

  Because if you exceed the designed operating range enough something bad will happen, expected or not. Yeah, it's probably fine but nobody wants to blow up a space shuttle.

  Part of the preflight that pilots have to do is calculate how much runway is needed for takeoff given the planes loading and current conditions. If the plane doesn't include data for the current temp, they can't run their calculations and fly. It's not that the plane itself can't fly in the heat, but they often aren't tested at very high temps due to lack of need.

  what I find strange is that big airport hubs like Abu Dhabi/Dubai in middle east get to 45-50 degrees quite frequently even outside of summer, there are tons of European/Asian companies flying there and I haven't seen/heard anything about any grounding. it's generally pretty harsh environment - pretty humid due to proximity to sea, and even in night temperatures stay high (been through there recently, after midnight it was still 40 Celzius)
