Best jetliner for hot and high airports?

Sat Jul 17, 2021 1:58 pm

I live in Albuquerque New Mexico which is over a mile above sea level and can get 100 degree + [F] days in the summer. In July I have seen many jetliners use up a lot of runway getting airborne.

Looking at Boeing takeoff performance charts it looks like the Boeing 737-600 has the best performance for hot and high conditions if it has the right engines. Looks like the old Boeing 720B was pretty good too. On many of the Boeing performance charts it appears that a lot of aircraft need to sacrifice weight to get performance at hot and high airports. The 737-600 seems less affected.

What about Airbus aircraft?

The smaller jetliners used by regional carriers seem to do better. But I don't have their performance data.

What do you know about this or what is your opinion? Thanks in advance to anyone responding to this question.

My vote is and always will be with the 757-200. When equipped with the right engines, this plane is an over-powered sled rocket that almost never flew out of PHX in summer weight restricted.

The length of the flight matters as well. Aloha Airlines tried using 737-300's inter-island, but the engines couldn't handle the short stage lengths in a hot climate. 737-200's, however, proved just right, and as we saw recently, there are many still there flying cargo. The 717 is doing quite well inter-island; however, what's next for inter-Hawaii flights?

757. some planes have better thrust to weight, but nothing is as lively as a 757. Power off of any runway one can find, plenty of climb performance, and with RB211s, that incredible sound. A319 and 73G can overpower a 752, but they cant recreate the 757 magic

Waiting for somebody to say that Boeing should restart the 757 production line...

An Airbus A319 will have no problem operating in those conditions. It should be able to take off at max structural weight up approximately 116 deg F.

I have heard that the 757-200 has second highest thrust to weight ratio of any commercial jet, behind concorde only. What is the comparison of the 752 vs the 73G/319 in a hot and high airport?

If airliners.net as a site had one signature/motto, this would be it.

Obv the 757.

Unfortunate there was no true replacement for it. The a319 and a321 both split up its mission; either large payload or takeoff performance, but not both.

I wonder how the MD-90 does in hot/high... I may have heard from somewhere that at its time, it had the most powerful rear mounted engines on any commercial airliner except for like Concorde or something. I wonder how the V2500-D5 does in the climate, even though this fact should not matter because they are all retired :(

757 was quite a ride.
I also love the WN 73G takeoffs out of BUR, also like a rocket ship.

DC-10-15, was a "hot & high" version of the DC-10 that both Mexicana and Aeromexico ordered for full capacity medium range operations out of MEX, such as JFK, LAX and ORD.

Correct me if I'm wrong, wasn't the VC-10 designed to operate from hot and high airports for BOAC to destinations in Africa / Asia?

Yes, in particular the original 'Standard' model. One of which later used by the Omani government routinely used an airfield in country where the largest aircraft prior to the VC-10 to have operated there was a Vickers Viscount.

Though range and a desire to not have customers like PA buy a tri-jet steered it's development, the Boeing 747SP as you can imagine was good for hot and high, hence SAA buying some in the 70's.

*Sarcasm font* We need to go a step further... Boeing should slap the GEnX on it and create a 757neo! Best field performance and long & thin capability ever!

While we're at it, does Boeing still have the tooling for the DC5? New engines and avionics... the perfect plane for regionals. To the moderators: Yes, I will stop now.

The BAC-146 was great for hot and high!

DL based the MD-90s at SLC for the hot/high performance that MD-88s lacked -- but then moved many to MSP post-merger because the mid-con location meant they could get anywhere in the US-48.

The A321NEO actually has a slightly higher Thrust/MTOW ratio than the 757. It also has 1.2x the wing loading, but for getting off a runway, I think T/W is more important.
