When the heel of the palm went down, the airpressure under the hand pushed the hand up. That’s called lift. The airflow over/under the hand changes with the shape of the hand or airfoil. If you had little cut-outs near your wrist, there wouldn’t be as much lift.

The tail section contains control surfaces for keeping the plane stable and controllable.

1) Horizontal: The horizontal, non-moving part is called the stabilizer, and it prevents uncontrolled up-and-down motion of the nose. The small hinged sections on each side are called elevators, which work in unison. It is controlled by the cockpit control wheel/stick and increases or decreases lift. When forward pressure is applied on the wheel, the elevators move downward, which increases the length of the tail causing more lift, which forces the tail upward, causing the nose to drop. There is also a small hinged section in the elevator which is controlled by a small vertical wheel on the cockpit console which is used to finetune the elebator trim. Hense the name trim tab.

2) Vertical: The vertical non-moving part which prevents the nose from uncontrolled swinging side to side. The large hinged section is the rudder. The rudder is controlled by the foot pedals in the cockpit, and deflects the tail to the right or left.

The wings generate most of the lift to hold the plane in the air. Different models of aircraft will have wings of different shapes and in different vertical locations. On a Cessna, the wing is high, and on a Piper, it is low. On an F14, the can change from a forward angle to “swept back”.

On most small planes, the wings also carry the fuel.

There are many control surfaces on a wing:

1) The aileron is the hinged part of the back of the wing towards the tip which is used to roll the wings from side to side. There is one on each side of the plane and they work opposite of each other. When one moves up, the other moves down.

2) Flaps are the hinged sections on the back of the wing near the fuselage. Flaps are deployed downward on takeoff and landing to increase the lift produced by the wing and allows the plane to fly at slower speeds.

3) Spoilers and Slats are used on high performance/commercial aircraft and also changed the aerodynamics of the wing.

Unlike conventional airlines that use ticket agents and travel agents and require you to buy your tickets in person, the low cost airlines made everything available through a simple and comprehensive website that everyone could understand and use. The method of selling air tickets became so popular that these airlines are teaching the more traditional airlines how to act and are leading the way in innovation in the sale and marketing of these flights.

All it requires to buy them is a credit card or debit card. You go to the website, select your details, that is your destination airport and your departing airport, and tell them what dates you wish to travel. Immediately you are quoted prices for all the flights on that day. If you can be flexible about your travel dates, they will also show you the prices for alternative dates and let you book those flights, which may be far cheaper. The system is so open and transparent that it is a major refreshment for those people that are used to dealing with traditional ticket agents.

The convenience doesn’t end there either. You can also add travel insurance to your flight and you have full coverage for the entire trip. They already know where you are going and how long you will be there so it is the perfect place to see travel insurance.

If you need accommodation, most low cost airline websites will quote you various hotel prices while your buying your flights and will tell you how much it would cost to stay in the city you are arriving at. It is very convenient. You can even arrange for car rental at the same time. You can pick up and drop off at the airport and all the details are already in the system so they can give you customised and accurate offers that will match your needs.

More and more customers are discovering the convenience of booking all of their travel arrangements at the one website, and all you need to do it is a credit or debit card, and a little imagination.
