According to the FAA, most aircrafts can safely fly over thunderstorms, but sometimes a thunderstorm can block a flight path. In that case, the plane will be rerouted to nearby airspace, and in extreme cases, to a neighboring airport.
Jet aircraft can safely fly over thunderstorms only if their flight altitude is well above the turbulent cloud tops. The most intense and turbulent storms are often the tallest storms, so en route flights always seek to go around them.
All planes are designed to fly through thunderstorms and have to comply with safety regulations. A rainstorm is unlikely to cause damage to the aircraft. The only danger of flying during bad weather is the risk of freezing rain, but in this case, your plane will most likely be delayed until the storm passes.
On August 2, 1985, strong and sudden wind gusts cause a plane crash at the Dallas/Fort Worth Airport in Texas that kills 135 people. The rapid and unexpected formation of a supercell, an extremely violent form of thunderstorm, led to the tragedy.
Rain is just water, no matter the pressure. Modern aircraft can generate lift regardless of the heaviness of the rain. Planes can and will take off and land in the rain. The only real problem with heavy rainfall is the decrease in visibility for the pilots.
Crosswinds greater than 50-60 km/h may cause airlines to delay or cancel flights. Even lower gusts can trigger flight delays or cancellations if the runways are wet or icy, as stiff winds can reduce a plane's ability to brake on the runway.
Flights may be canceled due to wind, precipitation, fog or low visibility, lightning, low clouds, or storms. Outside temperature does not always affect flights. Pilots make the final determination as to whether a flight will occur or whether one in progress will be diverted to another airport.
Numerous accidents have occurred in the vicinity of thunderstorms due to the density of clouds. It is often said that the turbulence can be extreme enough inside a cumulonimbus to tear an aircraft into pieces, and even strong enough to hold a skydiver. However, this kind of accident is relatively rare.
Pilots should observe the following rules for any flight routed even potentially near actual or possible thunder- storm activity: Avoid all thunderstorms. Never go closer than 5 miles to any visible storm cloud with overhanging areas, and strongly consider increas- ing that distance to 20 miles or more.
Turbulence, associated with thunderstorms, can be extremely hazardous, having the potential to cause overstressing of the aircraft or loss of control. Thunderstorm vertical currents may be strong enough to displace an aircraft up or down vertically as much as 2000 to 6000 feet.
Can a Plane Fly in a Thunderstorm? So, do planes fly in thunderstorms? Well, the simple answer is yes, they do. In fact, statistics show that thunderstorms have very little impact on flight schedules and are not likely to cause too many issues like delays or flight cancellations.
"Accidents are rare in aviation. There were five fatal accidents among 32.2 million flights in 2022," Willie Walsh, director general of the International Air Transport Association (IATA), said in a statement. "That tells us that flying is among the safest activities in which a person can engage."
Is it safe to fly in high winds? In general, the answer is yes. In addition to the fact that modern aircraft are designed to perform well in very high winds, pilots around the world must be able to demonstrate skill at flying in windy conditions in order to become licensed.
A leading reason for avoiding storms is simply to make the flight smoother. Strong winds can seriously affect aircraft movement. Most of this is due to clear air turbulence - caused by variations in wind velocity.
According to a 2018 TIME Magazine article, the last commercial plane crash directly caused by lightning occurred in 1967. Aircraft undergo specific lightning tests to ensure they can withstand hits as part of their certification.
What does IATA say about airport lightning rules? The International Air Transport Association (IATA) says to issue lightning alerts at 5 miles (8 km) and stop operations at 3 miles (5 km). They suggest using a 3-mile critical radius and resuming operations once the lightning activity has moved beyond this radius.
As a pilot, however, thunderstorms are one of the most hazardous conditions you can encounter. All thunderstorms can produce severe turbulence, low level wind shear, low ceilings and visibilities, hail and lightning.
During harsh weather, pilots will determine what control inputs they will require during takeoff. The crosswind might attempt to "lift" a wing and force the aircraft to move away from the runway heading. Preventing this situation is usually achieved by using the rudder input to keep the plane from rolling.
During inclement weather, the autopilot is normally used. In cases of significant turbulence, a pilot may disengage the autopilot to help ease the vertical loads on the airplane by reducing the corrective control inputs. All takeoffs and most landing are done manually.
The disruption in the air current which helps a plane to fly results in shakes and it is referred to as turbulence. Also known as air pockets, turbulence can cause a sudden loss of altitude temporarily.
Winter and summer are the most turbulent months to fly. During winter, there are strong winds and blizzards. During the peak of summer when it is very hot, convection turbulence occurs, especially when flying over cities and mountains during midday.
Question: How do pilots avoid anvil-head clouds and other signs of thunderstorms while flying at night? Answer: Pilots use onboard weather radar to remain clear of thunderstorms during day and night operations.
Call the Airline or Check Its Website Often
When you have an upcoming flight, you can typically get information on any potential delays or cancellations by calling the airline often or checking its website. Airlines usually update flight status last minute, posting official delays only when they're sure they'll happen.
Fog, snow, ice and crosswinds mean that air traffic controllers have to increase the gap between planes that are landing, reducing the number of aircraft that an airport can manage. The same weather can make it slower and more difficult for the planes to taxi between runway and terminal building.
Flight tracking apps and websites — FlightAware, Flightstats, and Flight Radar all track the departure and arrival of most commercial flights and are, without doubt, the best websites to check if your flight has been delayed, cancelled or diverted.
