Airplanes have luggage compartments on board which are designed for simple loading. Do you ever wonder if your luggage in the compartments is pressurized or not? We've scoured the internet and discovered the top answers to this query.
Luggage compartments on planes are indeed pressurized to keep the passengers and aircrew safe at high altitudes. The compartments have the same pressure as the passenger cabin.
You might also be curious if your luggage is safe and what environment they are in. We will discuss luggage compartments on the plane, how pressurization works in the compartment, and how cold it gets in the compartments.

Luggage Compartments On The Plane
Most aircraft are built to carry hundreds of passengers in varying degrees of comfort throughout the globe. The type of luggage passengers are permitted to bring along in the passenger compartment is called hand luggage.
The aircraft's compartments are temperature controlled. The structural design of the compartment consists of frames and stringers to which sheathing sheets are fastened.
These compartments are pressurized at the same pressure as the passenger cabin. A cabin pressurization system typically maintains a cabin pressure altitude of around 8,000 feet.
Pressurization systems are a component of the life support equipment needed to keep the aircrew safe during high-altitude operations. Passengers also need suitable air pressure and an adequate oxygen concentration in the aircraft cabin to ensure comfortable breathing.
This system encloses the cabin and baggage compartments in a sealed container that can hold air at pressures greater than the atmospheric pressure outside. It also helps reduce fuel consumption for a given airspeed while avoiding bad weather and turbulence above storms.
Some aircraft have additional safety features like pressure equalization valves and blow-in panels between adjacent compartments.
Remember that airport security inspects each piece of luggage, both hand and checked. Ensure to pack only permitted items because airport security personnel won't let anything through if they deem it unsafe.
Contact your airline immediately if you're unsure what you can bring as hand luggage.
How Does Pressurization Work In the Compartment?
The compartments do indeed have pressure. They can obtain the pressurized air from the turbocharger of a turbine aircraft.
Some vents allow the pressure to equalize. When pressure is created, the floor will put stress on the area where it meets the aircraft's skin. The airplane skin can contain the air pressure and transform it into a pressure vessel.
The outflow valve controls how much air flows out of a pressurized airplane and controls the cabin pressure or cabin altitude. It releases air into the atmosphere to maintain stable air pressure inside the cabin.
The outside ambient pressure rapidly changes during ascent and descent, which can be pretty uncomfortable for passengers. The ambient pressure is less than 5 PSI at elevations greater than 30,000 feet, which is inadequate for humans.
An airplane's pressurization system maintains a constant air pressure within the cabin even when the outside pressure varies to maintain passenger comfort and safety.
Does It Get Cold In The Luggage Compartment Of A Plane?
The conditioned air is diverted from the cabin, so the air is typically a little cooler when it reaches the compartment. Your carry-on usually is colder than the main cabin.
The bags don't get cold enough to cause things to freeze.
Can You Survive In The Cargo Hold Of The Plane?
It's unlikely for you to survive in a cargo hold of a plane. The area is under pressure, but there is oxygen deprivation.
The luggage on top of you would cause you to suffocate. You could fall or get crushed when the landing gear retracts mechanically into the wheel well. Despite being pressurized, cargo compartments can still be chilly, dark, noisy, and unpleasant places to be.
You might get hearing loss, severe cold, acidosis, or losing limbs if you survive.
Are Airplane Cargo Holds Pressurized And Heated?
These cargo holds are pressurized, heated, and insulated. It pressurizes cargo holds by bleeding air from the engine compressors.
Liquid cargo freezes and could explode if not appropriately pressurized. If the cargo hold isn't pressurized, all of the liquid cargo would burst and could potentially damage the aircraft and/or passengers' belongings.
The temperature in the airline cargo hold is regulated by heating or cooling based on the specific cargo being held to set it to a particular temperature.
For cargoes that include pets and livestock, it is set to be heated and pressurized to preserve comfort and keep pets safe since the temperature outside the cargo is too low.
But cargo that needs to be preserved at a very cold temperature is only cooled and not heated. The temperature of a cargo hold is greater than 40 degrees Fahrenheit (seven degrees Celsius).
However, the temperature of the cargo rooms will vary depending on the type of aircraft and its size and other engineering considerations.
The airplane contains an interior handle for the baggage compartment door. Once the plane is pressurized, the air pressure inside would prevent anyone from opening a door.
Is The Cargo Hold Safe For Dogs?
Many flyers are worried for their pets about the atmosphere in the cargo hold of aircraft.
Live animals can be kept and are safe in the cargo hold since it is pressurized. Also, animals flying at great heights can travel more comfortably due to climate control.
The cargo hold is a temperature-controlled environment and can provide enough air pressure and oxygen for pets to breathe.
Heat is frequently the main issue, but if live animals are put incorrectly into uncontrolled cargo holds, low temperatures could harm them.
You can guarantee your pet's safety in the cabin as carry-on luggage. However, only pets that can fit under the seat are permitted. Ensure to have a pet carrier cage for your pet.

Also, pets must be at least ten weeks old and have a veterinarian's up-to-date health certificate and immunization record to travel domestically. Pets are not permitted to board aircraft without climate-controlled cargo holds.
Why Do I Feel So Bloated After Flying?
Some frequent travelers experience bloating after the flight, commonly referred to as "jet belly".
It implies that internal pressure is greater than the external pressure, which results in bloating and general discomfort. Gas begins to expand as cabin pressure decreases while you're flying. You can have pressure in your stomach as a result.
Your body constantly tries to adapt to the changes it encounters during flying, from takeoff to landing. It works as hard as possible to maintain equal air pressure inside and outside during flight.
Your digestive system is set up to release the extra gas it has built up when it's time to descend for landing. Bloating can manifest as stomach pain and trouble passing gas. You can experience discomfort and detect a small amount of abdominal edema.
You can have a light breakfast before takeoff to avoid bloating. Drinking enough water can alleviate the effects of jet lag and jet bloat.
In Closing
Both the cabin and the cargo hold are pressurized. The primary purpose of pressurizing an airplane cabin is to provide passengers and the flight crew with a secure environment.
Pressurization is accomplished by the intake of compressed, conditioned air and its controlled discharge in the atmosphere. Before you go, check out these interesting posts that we have:
