I'm not exactly sure what the temp. is in Phoenix today, but I've heard of Tires beginning to melt and blow when it gets hot enough down there.

I've flown in and out of PHX on some of the hottest days in Summer (115 degrees+) and we never experienced delayes due to the heat or blown tires resulting from the heat. In fact, I spent 20 years in PHX and there were only two occassions where heat was a factor in delays. That occured in 1990 when PHX reached its all time record high two days in a row - 120 and 122. I guess they had to ground flights while the temp was at 120 or over because the high temp resulted in thinner air and less lift for full planes.

As Matthewroy stated, it's not hot today by PHX standards. Heard this morning that today's high here was not expected to top 95 degrees. BTW, I remember those 120 and 122 days in June 1990. I don't care if it was a dry heat - it was HOT!!!!!

Just wondering if something fell off an aircraft that was run over by another, causing the blown tires. Another cause can be a hard landing - and I do mean HARD!




Long live the RJ!

I was on a Southwest flight from BNA - PHX during those incredibly hot days. I remember the gate announcement delaying the flight due to heat.

Yep, it was still hot when we arrived.

During those two days in 1990, from what I have heard (and I can't verify the validity of it) from several people through the years is that they (I presume aircraft performance people?) hadn't calculated anything beyond 120F, and apparently now they have, because it hit 121F in 1995 and the airport continued to operate normally, I think. I've also heard (and again, I can't verify this) that the official airport thermometer was moved to a cooler location after that. I would like to know how true that is, though I wouldn't complain about it. It's nice to have gone nine years without a reading that high.

The week it hit 121 in 1995 was awful. I do not believe it got BELOW 110... possibly even 113 or 114. And to make matters worse when it is that hot you'd be lucky to fall much below 100 at night.

Even if the aircraft manufacterers developed performance numbers for such extreme temps, I am not sure that many of the rampers would be too happy to be out there in such extreme heat. Throw in a bunch of mobile hair dryers and all that asphalt and concrete it has to be brutal out there.

Actually if I am correct, the 120 degree mark has nothing to do with lack of lift through the thinner air (though it is a factor). But the performace charts onboard do not go above 120. Therfor without the performance chart they are a no go!

I don't know about the "blown tire". My co-workers & I were waiting for our inbound HP #186 (PVR-PHX) N166AW @ B27. It is scheduled to arrive in PHX @ 14:58. Around 14:15-15:00, there was a fast-moving weather system, which moved West to East.For 30+ minutes, there were no take-offs or landings on either north or south runways. All the taxi-out aircraft were held on the active taxi-ways. I witnessed a CO 737-700 & SWA 737-500, go-arounds on runway 25 (not sure if left or right). AWA had 2 737-300's taxi on Bravo to hold bay B-14. Our flight HP #186 diverted to TUS. It finally arrived @ 17:15.

If PHX had any 15-30 minute delays on Tuesday 8/24/2004, it was due to high winds, low-visibility, blowing dust & light rain. I was kinda bummed. I enjoy cloudy days in Phoenix, it's a rare occasion! The skies cleared-up & the sun came back out. doh!

Hope this helped you?

I worked my usual PM shift on Tuesday, so there may have been a different delay in the AM.

>>>Actually if I am correct, the 120 degree mark has nothing to do with lack of lift through the thinner air (though it is a factor). But the performace charts onboard do not go above 120.

Correct. There is a value called "MOT" (maximum operating temperature), and it's not the same for all aircraft/locations. I don't know what the MOT at PHX is for the Airbii family and the DC9/MD80 variants, but for JT8D-powered 737s, it is indeed 120F. For the CFM-powered 737s, it's higher, 126F. Even though PHX did briefly get to 122F some years back, it's a long way from 122F to 126F, and I doubt that you're likely to see the same effect on flights that it did a few years ago.

And, as far as the original question in the thread, it would appear that -somebody- blew a tire on the runway, and irrespective of whatever the temperature was, the essential fact is that the runway has to be checked for any tire debris before other landings/takeoffs. (You don't want subsequent aircraft hitting it it, or ingesting pieces into an engine.) It may take a few minutes to get someone out there, and another few to check the runway, but even taking a runway out of service for 10-15 minutes can produce delays, especially if it happens at a "peak" time.

I dont recall any delays Tuesday morning while I was at work, in fact everything seemed to go out on time or very close to on time. Maybe what you saw was just a glitch in the FAA computer system?
