The Dynamics of a Skid in Cars and Aircrafts
A skid is a kind slip practiced by drivers and pilots. The dynamics surrounding a skid are very complex and therefore any driver or pilot who tries this maneuver should be very careful since it can result in a very serious accident. However, the same principle can be employed to counter effects of a wrong turn if carried out carefully.
In order for a driver to achieve a skid he or she must skid steer the car. This is a method of steering that is achieved through the use of the braking system or engaging the wheels on one side of the car. Generally, a skid is achieved when the driver generates differential velocity at both opposite sides of the wheels. Another maneuver that can be used to achieve a skid is known as pivot steering. This is very common in tanks and involves changing the direction on the same spot, without having to go any distance forward or reverse, as is the case with a coordinated turn.
In aircrafts, a skid occurs in a more complex manner and a lot of air dynamics are involved. A skid in aircrafts often implies a kind of slip which occurs when an airplane is in a bank. This means there is uncoordinated air flowing from the side that has a raised wing. This normally happens when the pilot tries to speed up a turn by pressing the rudder pedal on the same side as the lowered wing.
Intentional skids are not advised when flying an aircraft. This occurs when the pilot is ready to make say a right turn from base to final. Instead of starting the turn smoothly, the pilot will apply a little rudder to the right. Crosswise airflow causes the aircraft to bank to the right and make a turn to the same direction. The pressure on the right rudder is maintained until the bank steepens then all of a sudden you press the left rudder. You will experience a skid that may be very dangerous.
