Like a huge cloud of volcanic dust stay here high above the clouds drift in the UK, a new "no fly" was imposed embargo. Today the sky is strangely empty and silent, never before in this country, we lived as a total ban on flights. NATS, the air traffic control, has made the decision Thursday, April 15. The volcanic cloud is a double-ended threat to the aviation industry. Not only reduced pilot visibility of millions of microscopicThe particles of volcanic ash can, vacuumed the dirt in the engines of aircraft and have them arrested. As I write this, Friday, 16, is the ban still in force and frustrated people are unlikely to be able to fly into or out of the country today.
All of this comes in the wake of recent travel chaos caused by a combination of natural causes and labor unrest. Commuter So far this year, pressures and travelers have suffered from excessive snow, strikesAviation and Cabin Crew rail, and now the fallout of an erupting volcano in Iceland. Who could have predicted that the geological events could be based on a small island far across the sea a devastating impact on daily life here in the UK? Flights were suspended even further with the arrest imposed in other European countries, including France, Sweden, Finland, Denmark and Holland.
Well, we could not predict a volcanic eruption of MountEyjafjallajökull perhaps, but the fact is that travel arrangements are subject to constant danger of a break from all types of events, both natural and man-made. Each company is worthy of a contingency plan is in place in order to deal with them, whether its employees are not able to get to work. By virtue of careful preparation and planning, and benefit from the use of modern web-based technology to your advantage, does not travel chaos spell financial chaos for the company.
ManyThe companies are now encouraging their employees to work from home instead of wasting time fighting for the office in adverse conditions. A (software as a service SaaS) solution could work from home much more efficient and productive than ever to help. Good service SaaS offers a wide range of useful features, the most popular include document management and file sharing, planning and resource management, time recording and business intelligenceReporting.
Some SaaS services can be expensive, but I managed, That one at the features I need for just € 7 a month to find. So I want to get a service that can access from my home, my office from my office clients, from a hotel room - where I always wanted to be. Forget the hassle of storing your files and folders on your corporate network, tie a geographical location. With my service SaaS can I organize all my files and folders, read and update and sharewith colleagues and customers, whether at home, at work or away.
transport problems are not the only reason you think should be working on your staff. You need to stay at home if your child is sick Minder out? No problem. Want to work quietly alone, away from the distractions of an office? Stay home and work in peace and at peace with SaaS. Do you have a cold and do not want to spread everything in the office? For God's sake, be sensible and stay home. WhyStruggle to find work, if you could do a lot more from the comfort of your home? Is your business really fall apart if you lose one day in the office? If the answer is "Yes" would suggest that you request to reconsider the plans for a matter of urgency.
For now we are back at the mercy of the elements. When the wind Iceland from the United Kingdom and Europe strike who knows how long flights are grounded? One thing I can guarantee, thoughthe volcano erupts and stops the wind direction changes, we are always on the go, the problems of one kind or another. Perhaps we are to live a blisteringly hot British summer, perhaps the asphalt starts to melt in the heat and prevent us from using our cars! Fat chance. It is very likely that we are another great block in the middle may have. But yes, seriously, your company continues to operate when the traffic stops, Get Right organizedhours.
Preparation and planning, as always, the key to financial survival. And now is the perfect time for the uninitiated, try to take advantage of SaaS for you: Get in the Internet, read the offer and there are many good deals and free trial versions. I can not wait to hold the next crisis, now!

The aircraft structures are the main wings, fuselage, tail e. The primary flight control surfaces are on the wings and tail, ailerons, rudder and elevators. These parts are sutures, articulations calls are connected.
All joints made with rivets, bolts or screws are special lap joints. Fasteners can not, joints which combines the materials used do not overlap - for example, Butt, tea and EDGE connections. Aboard Fayed is a type of lap jointwhen two metal surfaces to overlap so thick.
aircraft parts are realized in four ways: milling, cutting, bending and extrusion. The metal part is machined to a form of votes from the first and then either chemical etching or grinding is transformed into wrought iron. One part is stamped on, place in a press, and then heat treated.
Bent sheet metal parts are made by turning around the bend allowance, and the layoutProcedures. Extrusion is part of an aircraft, dies formed by forcing metal through a pre-formed. The resulting forms of wrought iron are used as trees, stringers, beams, or channels. To be folded metal foil, or must first be made and flexible heating. After forming the metal is still subjected to heat treatment and care.
Here in the UK and in particular to the site of Airbus in North Wales, is our expertiseManufacture of wings. wing aircraft must be strong enough to survive the flight positive forces and negative forces landing. metal wings are of two types: cantilever and Semicantilever complete. Semicantilever or braced wing aircraft are used to light. Are tolerated by struts or wires connecting the spar into the fuselage supports. Full cantilever wing is usually more than metal. It requires no external reinforcementor support. The skin has its wing stress. The shares, which are designs for both wings spars, ribs, compression, former ribs, stringers, stress plates, wedges. Wing tips and wing skins.
Airbus in Broughton employs over 5,000 people, mostly in manufacturing but also in engineering and support functions such as purchasing and finance.
Two or more trees for the construction of a wing are used. Carry the football longitudinal edge - the reactions of the sail.Both savings and a rib compression connecting the wing to the fuselage.
Compression ribs support the heaviest burden in the direction of flight, from leading edge to trailing edge. Some aircraft rib compression tube is a structural separation of two pillars. The main function of chest compression flight to absorb the force on the leg when an airplane.
A former rib, which is made of light,gives the stringers and skins, wings give the wing its aerodynamic shape. Former ribs can be classified as a rib nose, ribs and trailing edge rib halfway back and forth between the front and the rear wing spar. The ribs are not as primary structural members.
Stringers are extruded from thin sheets of aluminum alloy shaped by hand or formats. Running from front to back along the fuselage and wing to the rear wing tip. Riveting the wing, both the skinStringers and veins of gives extra strength.
Stress plates are used on the wings to support the weight of fuel tanks. Some plates of metal stress are thick and some are made of thin layers of corrugated metal. Stress-plates are usually held in place by rows of machine screws, with nuts, this thread channels specially fitted. The plate stress is channeled to the spars and ribs riveted compression.
Envelopes orGusset plates are used planes to join and strengthen the components intersect. The envelopes are used to load from one Member State to another place where members join.
The wing tip is the end outboard of the wing, two purposes: to regulate the flow of air from the tip of the wings and aerodynamic wing a're damage done.
Wing skins cover the inside and provides a flow of air over the surface of the wing.A full cantilever wing, stress skins. However, all the wing skins to be treated as primary structures, whether they are blocked or completely self-sufficient areas.
The largest aircraft structural components, there are two types of metal fuselages: Full monocoque and semimonocoque. The full monocoque fuselage used fewer internal parts, and one more than semimonocoque stressed-skin fuselage, internal reinforcementsto achieve its compactness.
Full monocoque hull is usually used on smaller aircraft, because the stressed-skin eliminates the need for Stringer, the former rings, and other types of internal bracing, so as to lighten the airframe.
Earnings semimonocoque hull its strength from the following parts: bulkheads, longitudinal, keel beam, drag struts, supports the body, ex-rings and stringers.
A bulkhead is a structuralPartition usually removes the hull, which is normally perpendicular to the keel beam and side guides. Some examples of places where the wing spars are Schott in the fuselage, where the domes are mounted pressure on the structure of the fuselage built, and for cockpit and passenger or cargo doors.
Longitudinal beams and keel
Longitudinal keel beam and the same function in a fuselage. Whether most of the load in the front and Travel. The stern and keel beam side, most sections of the cell, bind to their weight on the parts of other aircraft, such as power plants, fuel cells, and suspensions.
Drag Struts, and other accessories
Drag the body support struts and accessories are other primary structural members. Drag struts are used in jet aircraft wide section to bind the wings to the fuselage away. support the body and fittings are used for the structures that make up the bulkhead or mast support planSections.
Former fuselage stringers and rings are not the primary structural elements. Former rings are used to shape the hull. Hull Stringer runs to the front and rear are used for bulkheads and tie
Aircraft empennage section
The tail is the tail of the aircraft. It is a horizontal stabilizer, elevator, vertical stabilizer and rudder. The conventional tail section contains the same type of parts used inthe construction of a wing. The internal parts of the stabilizers and flight control with spars, ribs, stringers and skins produced.
In addition, rear sections such as wings, can be taken internally or externally.
Horizontal stabilizer and elevator
The lift is a primary control surface, which is connected to the elevator. The elevator leads to the nose to pitch up or down. Together, the horizontal stabilizer and elevator stabilitythe horizontal axis of the aircraft. In some aircraft the elevator is moving to a jack assembly allows pilots during the flight from the plane to be cut.
Vertical stabilizer and rudder
The rudder is connected to the rear of the fuselage and provides stability to the vertical axis. Connected to the vertical tail and rudder, which serves aircraft goits vertical axis.
Elevators and rudder are the primary flight controls in the tail section. Ailerons are the primary flight control system connected to the wings. In the outer part of the wing, allowing the aircraft axis to rotate about the longitudinal axis.
When the right aileron will move up to, go down to the left, making the plane roll to the right to open the file. Because this action generates an immense force to the ailerons are builtthereby, to resist.
Flight control other than the primary three planes, which are necessary for high performance. On the wings of a jet wide-body, for instance, there is so much a pm flight controls including aileron high and low speed, flaps and spoilers.
Flaps and spoilers
Flaps increase lift for takeoff and landing. inner and outer flaps on the trailing edge of the wing, at full speed from the top, which is neutral airflowThe position to be filled, so that air can accumulate and produce a thrust. Staves - they Krueger and variable - increasing the size of the wings and rope allows the airplane to launch or land on a runway shorter. Spoiler in the center section span-wise, located two purposes. They support high-speed ailerons in turning the aircraft during flight, landing and kill to lift the spread open during touchdown.
Connected to the primary flight control units are called flaps. Are used for airplanes with fine adjustments to the flight path of a. Flaps are like wings or ailerons built, but
