Answer :
Answer: Aircraft need to be pressurized primarily for the comfort and safety of passengers and crew at high altitudes where the air pressure is low. Here are the key reasons:
Breathable Air: At cruising altitudes, the air pressure outside the aircraft is significantly lower than at sea level. Without pressurization, the air inside the cabin would also become thin, making it difficult for passengers and crew to breathe comfortably. Pressurization allows for the maintenance of a breathable atmosphere inside the cabin, similar to what passengers experience at lower altitudes.
Preventing Hypoxia: Hypoxia is a condition caused by insufficient oxygen in the body's tissues. At high altitudes, where the air is thin, there is less oxygen available per breath. Pressurizing the cabin helps to maintain a sufficient oxygen concentration, reducing the risk of hypoxia among passengers and crew.
Temperature Control: Pressurization systems also help to regulate cabin temperature. At high altitudes, temperatures can drop significantly, posing risks of discomfort and even cold-related health issues for passengers and crew. By pressurizing the cabin, aircraft can maintain a comfortable temperature throughout the flight.
Preventing Structural Damage: Another reason for pressurizing aircraft cabins is to prevent structural damage to the airframe. Modern aircraft are designed to operate within specific pressure differentials between the interior and exterior of the cabin. Without pressurization, the pressure difference at cruising altitudes could lead to stress on the aircraft's structure, potentially causing damage or failure.
In summary, pressurizing aircraft cabins is essential for ensuring passenger comfort, safety, and the structural integrity of the aircraft, especially during flights at high altitudes where the air pressure is significantly lower.
