The Airbus A350 underwent extreme environmental evaluation inside a specialized aircraft lab in Florida during its certification campaign.
It’s somewhat ironic that such a lab is located in sunny Florida, but one of its key features is a massive main test chamber where the temperature can be artificially dropped to -40°F (-40°C) or even lower.
They even have specialized equipment to simulate snow, freezing rain, and severe ice accumulation.
But there’s a very good reason why that’s the case.
The coldest and hottest places commercial jets travel to
Excluding specific remote locations that are only reachable by specialized aircraft or other means of transport, the coldest and hottest places regular airliners travel to might surprise you.
It obviously depends on several factors, but, in general, the coldest place is Yakutsk, in the Russian Federation.
On average, the yearly temperature is 17.6°F (-8°C).

In winter, temperatures can drop below -40°F (-40°C).
Several commercial airlines operate regular flights there with standard passenger jets.

By contrast, the hottest place aircraft travel to is Kuwait International Airport in Kuwait.
In the summer, you’re looking at an air temperature of 115°F to 125°F (46°C to 52°C).
It gets worse when you read the temperature on the tarmac.
It can skyrocket past 150°F to 170°F (65°C to 77°C), presenting serious challenges for aircraft performance and ground crews.

How Airbus tests the A350
A while back, an Airbus A350 test jet stayed for more than two weeks inside McKinley Climatic Laboratory, which is located in Florida, of all places.
The hangar is equipped with chambers and hangars that can simulate almost any scenario, including snow and ice.
The chamber took it from a high of 113°F (45°C) a low of minus -40°C, the one point where Celsius and Fahrenheit read the same.

This is why Airbus tests the A350 to this extent
The A350 family is relatively popular; although it may not match the sheer delivery numbers of the A320 or A330, it operates across an exceptionally wide range of countries and climates.
The list of nations whose airlines operate at least one A350 is extensive.
It includes countries known for extreme cold, countries known for intense heat, and countries featuring diverse microclimates – spanning ultra-cold ice plains, scorching dry deserts, and humid tropical forests.
This list includes Canada, China, Brazil, Finland, the UAE, Spain, India, Kuwait, Thailand, Qatar, South Africa, and Switzerland.
