Procedure happens every day, is far from being an emergency and serves precisely to prevent a hazardous situation
The rush can happen moments before touching or during approach (Divugação)
The landing of an airplane must meet a number of criteria guided by a combination of equipment of the aircraft and control tower, calculations and the pilot's hand. If one of these steps is given before or after, or if any adversity arise along the way, like a strong gust of wind or a bird, the approach procedure is canceled and the commander rushes or, as explained Dan Guzzo, executive manager operational safety Gol company during a workshop of the company, "the landing is discontinued."
How to play in aviation, the landing is a "controlled fall." The approach procedure still get above the clouds, when the aircraft is authorized to enter the air landing, where the planes form a queue to get to the airport. During this phase the master decreasing altitude and initiates a series of commands to reduce the speed of the aircraft.
The aircraft's flight plan contains information about all procedures provided with a number of alternatives already scheduled for the event of an emergency or change of route, as well as all details about a possible rush to the final destination. "In aviation always working preventively," says Guzzo.
Visibility is one of the decisive factors for landing or missed approach. "When you're in the car and starts to rain, because the visibility conditions, we decrease the speed. On the plane, however, you can not do that, "compares the Gol security manager. "If the pilots do not see the inside track of what we call 'decision height', the landing is discontinued," he added.
When the missed approach procedure takes place, the commander drives the motors again with full force, gathering and landing gear starts to increase, following the programmed criteria when the aircraft was still on the ground at their point of origin. Then the aircraft back to the route and waits for control tower guidelines to make another attempt or move on to another airport.
"Hardly a plane will swoop twice. If this happens it will be because of very severe weather conditions. In addition, the commander already knowing the adverse conditions at the destination and having made an unsuccessful attempt, the most appropriate in this case is to land at another airport not to compromise fuel capacity, "said Guzzo.
The condition that most affect the visibility of aircraft that land in Brazil are fog and rain. In cold countries, the main challenge is the snow. "The crew should be able to see the runway within the limits set by the manufacturer or by the company even on aircraft and airports with equipment that can perform automatic landings," emphasizes Gol manager.
Wind shear
Another factor that may lead to a rush is wind. The most adequate for landing the aircraft is to fly with headwind, or against the wind. Suddenly there is a sudden change in wind direction, the approach is undermined and the plane goes back up.
A meteorological phenomenon called "Wind Shear" or "windshear" the English term used in aviation, can cause a critical reaction during landing, forcing the pilot to make sudden maneuvers compensation before swoop. The windshear is a sudden change in wind direction or intensity. "It's like stopping the treadmill where you are running from one moment to the next. Or the treadmill instead of running back starts to move aside, "says Guzzo. "A piece of equipment aboard the aircraft called" Predictive Windshear "can predict these events," reassures the operations manager and safety of Gol.
The side wind, even strong, is not an element that can affect the landing. In such cases, the plane needs to direct its beak into the wind, causing the classic effect of "next landing" when the plane aligned with the runway moments before touch.
Abort landing
When the aircraft touches the runway but must return to take off it is not considered a rush, but a "landing abort". This will happen because the speed conditions and track, which in some cases can count extent enough for a new twist. "According to recommendation of the aircraft manufacturer, after reverser be triggered are advised to take off again with the aircraft," said Guzzo.
The reverser is an engine feature that frea the aircraft to direct the flow of the jet in the opposite direction. For security, the reversers are triggered only when the aircraft is already with all the landing gear wheels on the track. The aircraft also has powerful brakes on the rear wheels, with steel or carbon discs, most suitable for short runways, and at the time of landing the crew drives all flaps and baffles wings, which act as brakes aeronodinâmicos.
You do not have to be afraid
Rush is a safe procedure that is not made may lead to a disastrous result. It is common in aviation and they happen every day everywhere and do not deserve to be treated as "emergency". How do you analyze the security director and operations Goal: "better pilot than trying to swoop landing".
