What is the importance of aircraft pressurization system?

Definition. A system which ensures the comfort and safety of crew and passengers by controlling the cabin pressure and the exchange of air from the inside of the aircraft to the outside.

What will happen to a pressurized aircraft if the pressurization system fails?

Effects. Crew Incapacitation. Depending on the altitude of the aircraft when depressurisation takes place, loss of pressurisation can very quickly lead to the incapacitation of the crew and passengers unless they receive supplementary oxygen.

What is service life of aircraft?

The average life cycle of an aircraft, from purchase to retirement, is between 20 and 36 years, depending on the model.

Why do you think it’s important for aeronautical engineers to be able to determine the center of gravity for an airplane?

The center of gravity is the average location of the weight of the aircraft. The weight is actually distributed throughout the airplane, and for some problems it is important to know the distribution. The total weight of the aircraft is simply the sum of all the individual weights of the components.

What is aircraft pressurization?

Cabin pressurization is a process in which conditioned air is pumped into the cabin of an aircraft or spacecraft in order to create a safe and comfortable environment for passengers and crew flying at high altitudes.

What happens when an airplane pressurized?

When a cabin depressurizes, the percentage of oxygen in the air stays about the same, but the molecules get further and further apart, Padfield explained. Then the air expands through an expansion turbine that cools air in the same way you can cool air by blowing it out of puckered lips.

What is aircraft life cycle?

The life cycle of an aircraft consists of design, production, operation and decommissioning phases. For an airline the main focus is on the maintenance process during the operation phase. This paper presents a case study of an airline facing a challenge of increasing maintenance cost.

How is aircraft service life determined?

The lifespan of aircraft is determined by the manufacturer. The age is calculated based on pressurization cycles. As a rule of thumb, each cycle involves “takeoff/landing.” Fuselage and wings suffer stress from pressurization, including on “short hauls.”

Why is it important to understand the load factor and how it affects when a wing stalls?

If the load factor becomes so great that an increase in AOA cannot provide enough lift to support the load, the wing stalls. Since the stalling speed increases directly with the square root of the load factor, the pilot should be aware of the flight conditions during which the load factor can become critical.

Why is it important to find center of gravity?

Therefore the location of center of gravity is an essential parameter to determine the flight characteristics of an object. Controlling the flight of an object necessitates good knowledge of its center of gravity location. The lower the center of gravity is, the more stability the car or truck has.
