Aircraft Pressurization System Airplanes‚ which do not have pressurization and air conditioning systems‚ are usually limited to the lower altitudes. They need to stay below 8‚000 feet. A cabin pressurization system accomplishes several functions in providing passengers comfort and safety. It maintains a cabin pressure altitude of approximately 8‚000 feet at the maximum designed cruising altitude of the airplane‚ and prevents rapid changes of cabin altitude‚ which may be dangerous to the passengers

Designing a Safer Passenger Aircraft Introduction to air safety: Aircrafts have become more advanced and fast‚ but they are drastically affected by ignorance and design incapability. However these structures can fly with more than 200 passengers and heavy cargo‚ but when they crash‚ they take away with them many lives and damage valuable property. To prevent such loses several aviation safety agencies like EASA(European Aviation Safety Agency) and FAA(Federal Aviation Administration) have been

Aircraft structures Abstract: The aircraft structure is an important part where the structure of an aircraft depends on the optimum requirement of the customer and the environments in which it will be going to fly for the major time. It has to go several checks at regular interval of flying hours under proper inspection. This paper contains the basic information regarding the components of an aircraft and the basic concept of its design. The main criteria of design and its philosophy is the

I. LANDING GEAR SAFETY DEVICES Most airplanes with a retractable landing gear have a gear warning horn that will sound when the airplane is configured for landing and the landing gear is not down and locked. Normally‚ the horn is linked to the throttle or flap position‚ and/or the airspeed indicator so that when the airplane is below a certain airspeed‚configuration‚ or power setting with the gear retracted‚ the warning horn will sound. Accidental retraction of a landing gear may be prevented by

New study area This week I have learned more about the interior part of the aircraft which is the cabin layout in most aircraft . Seats are frequently equipped with further amenities. Airline seats may be equipped with a reclining mechanism for increased passenger comfort‚ either reclining mechanically or electrically (usually in long-haul first class and business class). Most aircraft also feature trays for eating and reading‚ either in the seatback which folds down to form a small table

What Are Aircraft? Everyone has seen a jet streaking across the sky leaving a trail of vapor as it goes. Maybe you have heard the distinct thud‚ thud‚ thud as a helicopter slows in its descent. You have probably marveled at a plane so massive that it seems to just hang in the air by some invisible force. These wonderful marvels of human engineering have captured the hearts of many. They are known the world over as aircraft. But what is an aircraft? Aircraft’s are comprised of many different things

looking into history. Studying the airplanes of the World Wars will reveal their function‚ effectiveness‚ and inform about the pilots who flew them. The aircraft for World War I (WWI)‚ and their purpose‚ greatly differed from those in World War II (WWII). Their value was defined by the author R. G. Grant‚ who said‚ “The principle role of aircraft in World War I was to support the armies in the trenches.” Basically‚ the army on the ground was viewed as the primary fighting force of the war‚ not airplanes

Similarities and Differences between Monopolies and Oligopolies WHAT ARE SOME SIMILARITIES AND DIFFERENCES BETWEEN MONOPOLIES AND OLIGOPOLIES? According to Mankiw‚ N. G. (2004) monopolies and oligopolies can be defined as: Monopolies are based on a market where there are several buyers but only one seller of a product or service whereby the seller sets the price for products and services provided. Oligopolies are based on a market where there a few companies own or control the production of a
