Aircraft Icing

Summary Aircraft icing is a common and serious danger in the aviation industry. Depending on the condition, icing may have little or no effect on the performance of the aircraft. We will explain the types of ice formation, the variables of each icing form, and the severity level that form and aircraft the aircraft. There are various prevention and treatment methods, and all pilots should be proficient in flight rules and regulations concerning avoidance and icing response. Aircraft icing It is troublesome for aircraft to freeze, which is a great risk for the aviation industry.

Flying icing From 1989 to the beginning of 1997 NTSB stated that about 11% of all weather related accidents of general aircraft were caused or caused by flight arrival ice. In air taxis / commuting and agricultural aircraft, about 6% of weather-related accidents point to freezing. Civil air transport accident rate is 3%. The ATR-72 accident occurred in the vicinity of Rose Lawn in Indiana in 1994 and 68 people died in freezing condition. Ice icing during flight is not only dangerous but also greatly affects the efficiency of flight operation. Rerouting and delay by commercial telecommunications carriers (especially regional telecommunication carriers and commuting airlines) to avoid icing conditions leading to delayed arrivals and chain reactions throughout the NAS. Changes in the way will incur additional fuel and other expenses for all types of aircraft

Aircraft icing can be overcome in a number of ways, and these methods can be categorized into two sub-themes: anti-icing and anti-ice protection. De-icing is a measure taken to remove ice formed on the structure of the aircraft. This deicing procedure can be accomplished with a mechanical or pneumatic tool or with a heated deicing fluid. Mechanically the de-icing shoe is mounted along the leading edge portion of the wing and along the horizontal and vertical stabilizers. Boots are made of natural rubber and rubber cloth, between which there is an inflatable tube. Next connect the tube to the air supply. During operation, use a pipe to push air into the boot, thereby increasing the pressure, resulting in weakening of the connection between the ice and the aircraft and the ice falling.

De-ice Boots - Rubber boots are attached to the front edge of aircraft wings. The aircraft inflates the boots with air and removes the accumulated ice with ice. The unacceptable danger of using this method in MSP is that the system must be started just before the formation of a large ice layer and it hits the rest of the aircraft when the aircraft falls. Employees push ice out of the plane using a brush or cloth. This method can be easily executed by MSP because necessary equipment is very inexpensive. However, when employees scrape ice, maintenance costs for the aircraft may be very high as they are more likely to damage the aircraft.
