Thunderstorm weather will cause great inconvenience to people's travel, especially for aircraft, which is more easily affected by the weather. Thunderstorm days will directly lead to flight delays. What problems should we pay attention to when we travel by plane in thunderstorm days? What impact will thunderstorm weather have on flight safety? Let's see.
Plan early, start early
Lightning weather is one of the weather that directly endangers flight safety. If an aircraft takes off, lands and flies in the lightning, the accumulated lightning in the air will cause damage to the fuselage and equipment, and in serious cases, it will cause the disintegration of the aircraft and cause major safety accidents. Compared with thunder and lightning, the impact of rainfall on the airport is relatively small, but heavy rainfall is easy to cause low visibility, obvious undercurrent, and most of the heavy rainfall is accompanied by lightning weather, so it is very easy to cause flight delay in thunderstorm weather.
For passengers, in Thunderstorm Weather travel must do two 'early' -- travel early plan, go out early start. Early planning means that passengers should pay more attention to the weather forecast of the departure and destination airports in the next few days before they are ready to travel, so as to understand the weather conditions and avoid thunderstorms as much as possible. Once the itinerary is determined, more attention should be paid to the flight dynamics. Although the airlines will inform the passengers through various channels in case of large-scale flight delays, it is generally difficult for airlines to inform the passengers of some temporary flight cancellations and delays in a short time, so it is very necessary for passengers to actively inquire and understand the flight dynamics.
Early departure means that passengers should take full account of the traffic congestion and poor information easily encountered in thunderstorm weather, and travel early to avoid missed flights due to the above reasons. Before going out, you can dial the consulting telephone number of the airline you take, or directly dial the civil aviation information inquiry telephone number. You can also know the latest trend of the flight and the time of departure and arrival through the microblog, wechat and other new media of airlines and airports, so as to arrange your own itinerary.
Select the early transfer time
Although thunderstorms occur frequently in summer, generally speaking, thunderstorms rarely occur in the morning, mostly in the afternoon, which makes morning flights less affected by the weather. It is suggested that passengers book tickets as early as possible, and it is better to choose the morning flight. In addition, if the weather of the route is not suck, passengers can choose the way of the curve to choose the route, and choose different airports to stop and make sure the journey is safe and smooth.
For passengers who choose transit flights, they should also fully consider the impact of weather factors on flights, and reserve sufficient transit time when purchasing connecting tickets, so as to avoid the delay of previous flights leading to serial delays, thus disrupting the travel plan. The reporter learned that according to the relevant regulations of civil aviation, there must be more than 4 hours of connection time for international flights and more than 2 hours for domestic flights. The airline does not bear any indirect responsibility for the connecting flights other than the airline.
In addition, in order to minimize the loss of flight delay, passengers can buy a flight delay insurance. At present, a number of airlines have launched this kind of insurance. Passengers only need to spend 20 yuan more when buying tickets. When the insured takes a flight with a valid ticket purchased by himself, due to natural disasters, bad weather, mechanical failure, hijacking, strike or temporary protest of the carrier's employees, terrorist acts, air traffic control or overbooking of the airline tickets, and other non-profit insurance If a passenger's flight is later than the scheduled departure time or cancelled due to his own reasons, he can get a certain amount of compensation, ranging from 200 yuan to 400 yuan.
Delay can be signed to protect rights
In case of flight delay due to thunderstorm weather, passengers should not be too anxious. Airlines and airports will start the plan and do a good job in relevant explanation and resettlement, such as information notification, distribution of free meals and handling of refund and change procedures. At this time, what passengers need to do is to pay close attention to the update of flight dynamics, and pay attention to the adjustment of gate, boarding time and other information.
In addition, according to the regulations, most airlines can refund or change tickets for passengers in full for flight delays caused by weather. It is worth noting that when handling the ticket change and refund procedures, passengers should also understand two points: first, passengers need to refund at the original purchase point; second, they should pay attention to the restrictions on some special tickets. Under the promotion of various airlines, many passengers buy tickets with 30% discount, 40% discount or even lower discount. However, these cheap tickets often have more restrictions on passengers, such as not being able to sign or change flights. Therefore, passengers who buy low price tickets must have a clear understanding of their flight restrictions to avoid unnecessary losses.
It is necessary to remind the passengers that the flight recovery after flight delay is a complex process. Never quarrel with the staff because your flight fails to take off at the first time, or even damage the airport facilities, beat the staff, strike or occupy the plane, because these behaviors will violate or violate the civil aviation safety regulations of the people's Republic of China According to the relevant laws and regulations of the people's Republic of China, the law of the people's Republic of China on the punishment of public security administration and the criminal law of the people's Republic of China, the relevant actors will also bear the corresponding legal responsibility because of their own impulse. Therefore, when the legitimate rights and interests of passengers are violated, they should maintain rationality, safeguard their legitimate rights in a reasonable and legal way and channel, and fulfill the corresponding legal and moral obligations of citizens.
Q: What is the impact of thunderstorm weather on flight safety?
A: The influence is mainly manifested in the following aspects: first, strong electron current forms lightning strike. If the aircraft encounters strong electron current, its radome, antenna, wing and so on may be damaged, which may lead to body ablation or flight accident. Second, the aircraft aerodynamic performance is seriously reduced due to ice accretion. The icing in cumulonimbus clouds is more severe than all other clouds. According to statistics, when flying in cumulonimbus clouds below zero degrees Celsius, the occurrence rate of ice accretion is 89%, and the occurrence rate of strong ice accretion is 42%, which can easily lead to engine flameout and serious degradation of aircraft aerodynamic performance. The third is strong airflow and windshear. The strong vertical airflow movement will cause strong turbulence and disturbance. Once the aircraft enters the disturbance area, it will be difficult to be manipulated, easy to lose control and even crash due to stall. The fourth is low visibility and wet runway. The short-term heavy rainfall caused by thunderstorm is easy to make the visibility suddenly low and the runway wet and slippery, and the low visibility will affect the pilot's sight and judgment. When landing, it will lead to high, floating and jumping, which is easy to cause difficult control or body damage. When taking off and landing on the wet runway, it is easy to cause the aircraft to rush out or deviate from the runway.
Q: The weather at the departure and destination is very good. Why did you tell us that the flight was delayed due to thunderstorm?
A: This is related to the mode of flight operation. Different from ground transportation, the operation mode of civil aviation flight is not a simple point-to-point round-trip transportation from point a to point B, but a continuous multi-point transportation from point a to point B, from point B to point C, from point C to point D, and even from point d to point E. The departure and destination of different passengers are different, but the four sections from point a to point e are carried out by one aircraft. If the flight from point a to point B is delayed, the impact will affect all subsequent points.
In addition, the route is a vertical space with a certain width and height between two points and a certain navigation ability. Different flights are designated to fly in the three-dimensional 'pipeline' at different altitude levels. In case of thunderstorm and other bad weather, the flight will not be able to pass. The thunderstorm area near the airport will also produce the above complex and dangerous meteorological conditions, so for the sake of flight safety, sometimes the weather in the destination city is good, and the thunderstorm area appears on the route or around the airport, and the flight will still be delayed.
Q: After the delay, can you choose the transfer flight at will?
A: No. It is understood that flight delay transfer must follow certain rules. In the process of signing and transferring, passengers may encounter the problem that different airlines are not allowed to sign and transfer. This is because some airlines do not have signing and transferring agreements, so they can not sign and transfer each other. They can only sign and transfer passengers to the same airline or airlines with signing and transferring agreements.
The delayed passengers can only occupy the remaining seats of the subsequent flights when they sign the subsequent flights. If the flight transfer is carried out in the same airline, the staff will directly transfer the passengers who have not gone through the check-in procedures to the subsequent flights; if the flight transfer is carried out between different airlines, the staff will receive the transfer passengers with alternate instructions. For the passengers who have completed the check-in, the attendant shall organize the passengers according to the number of passengers who can be transferred according to the check-in notice, take the passengers to the boarding gate of the changed flight in advance, and notify the transferred passengers to board with the original boarding pass. When boarding, the boarding gate is scanned according to the respective flight, and the passengers who delay the flight are not seated in the right number.
When the subsequent flight can not receive all the passengers of the delayed flight, the positions of important passengers, head cabin, gold card, silver card, special passengers and international connecting passengers shall be reserved in advance, and the transfer and change of tickets shall be arranged in advance.
