Is a 737 cargo hold pressurized?

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.

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.

You should have no concerns about temperatures in the cargo hold. According to a 1996 New York Times story, Federal Aviation Administration tests showed that temperatures inside pressurized luggage compartments ranged from 65 to 70 degrees, comparable to passenger compartments.

Mechanical ventilation systems actively blow air across or through the cargo hold to remove hazardous gases or vapours. If the cargo is prone to self-heating in the presence of moisture, mechanical ventilation should be applied in specific circumstances only.

Rules on when to ventilate Dew-point rule Ventilate when the dew point of the outside air is lower than the dew point of the air in the hold. Three-degree rule Ventilate a hygroscopic cargo if the temperature of the outside air is at least 3°C below that of the cargo temperature (taken at loading).

Air pressures on FedEx Express aircraft vary from as low as 8.3 psi at cruise altitude to as much as 14.7 psi on the ground.

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.

The whole process of flying can be stressful for a dog, but those levels of stress can be greatly reduced with a few simple home comforts and reassurances. Ensuring your flight is a non-stop flight rather than one with changeovers can be a huge benefit to your dog, as can looking to travel at a suitable time.

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.

MORE DETAILS

Most aircraft cabins are pressurized to an altitude of 8,000 feet, called cabin altitude. Aircraft pilots have access to the mode controls of a cabin pressure control system and – if needed – can command the cabin to depressurize.

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. But only animals small enough to fit beneath the seat are allowed: A cat, a rabbit, or a Maltese is fine; a full-grown Labrador isn't.

Hold preparation may include several steps including dry sweep, removal of previous cargo residues, freshwater rinse as well as final inspection. Ventilation is often overlooked but in fact, it the easiest and most effective way to ensure your cargo's integrity throughout the voyage.

MORE DETAILS

Baggage and cargo go either held in place by netting or stored in containers (bulk holds) or on pallets (palletised holds). In bulk holds, the standard technique for loading and unloading is for one or two operators to enter the hold to place or remove the containers.

MORE DETAILS

For ship sweat to occur, the dew point in the cargo hold must exceed the temperature of the ship's structure. To eliminate ship sweat, the cargo should be ventilated if the ship is moving from a warm to a cold climate.

The co2 is released by opening appropriate valve for the hold after confirmation and discussion with the captain of the vessel or ship.

MORE DETAILS

The cargo hold is pressurized and temperature controlled, with the temp usually at about 20 degrees colder than the cabin (at altitude).
