Yes, there are most temperature listed in the efficiency charts. If the temperature exceeds the flight can’t depart.
In some instances it might be doable for the operator to contact the producer and procure the wanted efficiency data. I had this occur one hot summer time afternoon in Phoenix. The most temperature was 110F and whereas we have been on the floor it exceeded that. Our dispatch workplace obtained efficiency data from Boeing for our particular flight and that was despatched to me permitting us to depart after a slight delay.
At very excessive temperatures, the quantity of payload an plane can carry could be restricted. Offloading cargo and/or passengers is typically vital as the hot air is not as dense decreasing obtainable raise.
You recently wrote that it is possible to overfly a hurricane whereas staying away from the storm. Do many flights really do this?

There are contingencies thought-about corresponding to diversion airports, in the above instance, Bermuda might be a good risk together with home cities not predicted to be within the storm’s path like Jacksonville, Florida.
Normally, flights keep away from the path of the storm however in some instances it is sensible to overfly them.
It’s laborious to say how a lot time is added to flight time by going over or round a storm. In some instances, the extra flying time is nominal whereas in others, it might might be up to an hour.
