Cargo air jets are typically pressurized to about 75 kPa, which is normal atmo- spheric pressure at an altitude of 2438 m. Temperature is maintained at approximately 20–23 °C.

According to estimates released by the Department of Transportation, less than 1 in 10,000 animals were injured, lost, or killed from flying. That said, the general safety of flying your pet as cargo doesn't discount the gravity of the fact that animals are sometimes harmed by flying in the cargo hold.
Yes, the luggage compartments of an airplane are pressurized and temperature controlled. This is to ensure that all items stored in the compartment remain safe during flight.
Commercial aeroplanes, both freight and passenger do not fly at a particular altitude without the support of pressurisation. For commercial aircraft, pressurisation provides shipping comfort, temperature control, and structural support of the consignments.
If asked in one word, it's yes. Most commercial air freighters predominantly use pressurised fleets. The majority of cargo that is shipped requires temperature and pressure controls. The temperature of the cargo is controlled via the pressurisation system.
Many are surprised to hear that the cargo hold in the belly of an airliner is pressurized. Conditioned air is directed from the cabin, so the air tends to be a little cooler by the time it reaches the cargo areas, which are also less insulated than the cabin. Cargo temperatures vary in our fleet.
Flying in the cargo can be a harrowing experience for any animal. It's loud; it's turbulent; and it's full of bizarre sites, sounds, and smells. It's not uncommon for animals to injure themselves by trying to claw or chew their way through a carrier.
The cargo hold is climate-controlled and will not be colder or hotter than cabin temperature. A pet-friendly airline will make sure your pet is comfortable at all times. Many airlines have temperature embargoes to deal with extreme temperatures.
Actually, it's fairly often that you can hear dogs barking in cargo when you're seated in first class. Usually you can hear them during the boarding process and soon after landing.
Undeniably, cargo is the more dangerous option for pet travel. The safest way for any animal to fly is in the cabin as carry-on luggage, provided that's an option.
If it's a passenger aircraft with frieght and baggage underneath, it will be at about the same temperature as the passenger cabin. The same pressurised air goes through both compartments. You would not want a frozen pet dog brought out of the baggage area would you?
Typically, cargo fire suppression systems have an initial high-rate knockdown discharge, followed by a low-rate metered discharge of Halon 1301, designed to keep the fire suppressed for continued safe flight and landing at the nearest suitable airport. Halon can be discharged into the forward or aft cargo compartment.
The Cabin Altitude of a pressurised aircraft is normally maintained at and altitude of 8,000 ft or less as a compromise between the physiological needs of the crew and passengers and the structural limitations of the aircraft. At 8,000 ft the use of supplemental oxygen is not required.
This valve controls the cabin pressure and also acts as a safety relief valve, in addition to other safety relief valves. If the automatic pressure controllers fail, the pilot can manually control the cabin pressure valve, according to the backup emergency procedure checklist.
Federal Aviation Regulations say that without pressurization, pilots begin to need oxygen when they fly above 12,500 feet for more than 30 minutes, and passengers have to use it continuously above 15,000.
Most planes flying today use a cabin pressure control system that ensures safe and normal breathing for everyone onboard during flight. The general rule is that planes should have cabin pressurization when they go above 10,000 to 14,000 feet.
Today all airliners are pressurized, and although the details vary among them, the basic elements of cabin pressurization systems are almost universal. Air is pressurized by the engines. Turbofan engines compress intake air with a series of vaned rotors right behind the fan.
