American Airlines Cancelling Fifty Flights

AA has cancelled fifty flights in Phoenix. Why? It's too hot! Their planes can operate safely at up to 118°. The forecast today is 120°. Wow!

Well, when you live in a desert you can expect there to be some heat. The humidity is only around 8% so it only feels like 115. LOL

Exactly! Think about how a turkey looks after spending time in that dry heat.

Picked the gf up at JFK just last night, and she flew in from Phoenix, and boy are her arms tired...sorry....Yeah, she told me that some flights were cancelled due to the heat because SOME planes can't fly in extreme heat. Obviously, the plane she flew back to NYC on was fine.

Santa Fe, New Mexico has the same problem. Severe heat coupled with the higher altitude of 6,000 ft thins the air so much some planes can't get the lift they need.

Hey Jerry, we're having a cooling down day today, only getting 117.

I doubt it will get above 80° here. A friend from Gilbert, AZ sent a picture from her home: 120°!

I transited Death Valley back in 2009 and it was 124 with a 20 mile sand filled wind blowing at 9:00 p.m. So, I drove enough to get thru it as I did not want to try to sleep in the motor home at that heat as the air conditioning does not work well at that temp. Will never forget it.

My brother-in-law and his wife from Phoenix are visiting us now, and they say this is a common occurrence, and it has to do with the size and power of the planes. Commuter-sized and smaller planes have problems, but the big boys keep coming in and out. Their son-in-law is a flight instructor there, and their planes don't fly when the temperature reaches 117 degrees.

Temperature is an FAA required certification limit set by the airplane manufacturer. Takeoffs above that limit are quite possible, but would be illegal. The most common number is 118 degrees but higher limits can often be had if the operator wants to pay the manufacturer to calculate and provide them. But it's expensive and airlines generally feel over-the-limit temps don't occur often enough to justify the extra cost.

I remembera time there where the temperature was over 120 for fourteen days in a row..
