For many nervous flyers, the most terrifying part of the flight isn’t cruising at 38,000 feet—it’s take-off and landing. These are the moments when the aircraft is closest to the ground, manoeuvring at lower speeds and relying heavily on precision. This proximity to terrain makes it easier for passengers to imagine worst-case scenarios, particularly if the aircraft encounters sudden motion or unexpected changes in direction. Among the most misunderstood phenomena in this context are windshear and microbursts—two types of rapidly shifting wind patterns that can feel jarring from the cabin and are sometimes discussed in the media as factors in older aviation incidents. But what do these terms really mean? Can they cause crashes? And more importantly, what do today’s pilots know—and do—to protect against them?
Let’s break it down in full. Because like many aspects of flight that cause anxiety, windshear and microbursts sound far scarier than they are, especially when taken out of their real-world context. The truth is that aviation’s understanding of these phenomena is now so advanced—and pilot training so rigorous—that these once-dangerous weather effects are now routinely detected, avoided, and managed with high precision. You’re not flying on hope. You’re flying inside a system that plans for this.
Windshear is defined as a sudden change in wind speed and/or direction over a short distance in the atmosphere. It can occur at any altitude but is most critical during take-off or landing, when the aircraft has less vertical space to recover. A microburst is a type of low-level windshear associated with severe thunderstorms, where a powerful downward column of air strikes the ground and spreads outward in all directions. These are particularly strong and can rapidly change the wind environment around an aircraft that’s climbing or descending.
But here’s the most important thing to understand: modern commercial aviation doesn’t simply react to these events. It anticipates them. Through a combination of onboard technology, airport weather systems, flight planning tools, pilot training, and strict operational rules, windshear and microburst threats are identified early and either completely avoided or handled with precise, practiced manoeuvres.
Let’s start with detection. In decades past, one of the reasons windshear was so dangerous was that pilots didn’t know it was coming. Today, that’s changed entirely. At most major airports, especially those prone to convective weather, dedicated ground-based windshear detection systems are installed. These include Doppler radar and Low-Level Wind Shear Alert Systems (LLWAS) that monitor wind flow across different points on the airfield. If a sudden shear is detected—say, a drop in headwind or a shift in direction—an automated warning is issued to air traffic controllers, who immediately pass that information to inbound or departing aircraft. In many cases, pilots are advised to delay take-off or enter a holding pattern until the conditions pass.
But the protection doesn’t stop at the ground. Modern aircraft themselves are equipped with predictive windshear detection systems, often integrated into the weather radar. These systems can scan the air ahead of the aircraft’s flight path and identify signatures of shear-inducing air movement, such as microburst outflows or downdrafts. If a potential threat is detected, visual and audio alerts warn the crew well in advance. In fact, one of the most common messages in simulator training and real-world operations is “Windshear ahead—windshear ahead,” which gives pilots the time to change course, delay descent, or execute a go-around long before entering the affected zone.
And then there’s the training. One of the most reassuring aspects of commercial aviation is just how much preparation goes into handling rare but critical scenarios. Windshear escape manoeuvres are a mandatory component of every commercial pilot’s simulator training—and not just once, but repeatedly throughout their career. Pilots learn and rehearse the exact pitch, power, and aircraft configuration needed to safely exit windshear conditions during climb-out or approach. These drills are performed under simulated conditions more extreme than anything they’re likely to see in the real world. If windshear is encountered, the response is muscle memory. There’s no guessing. No experimentation. The procedure is clear, immediate, and highly effective.
Let’s go even further into what actually happens during a windshear encounter. Imagine an aircraft on final approach. The wind is steady from the front, helping slow the plane and improve lift. Suddenly, the aircraft enters a microburst. First, there’s an increase in headwind—lift and airspeed momentarily increase. Then, a sudden downdraft pushes the aircraft downward. Immediately after, the headwind turns into a tailwind, reducing lift and airspeed quickly. Without correction, the aircraft could descend faster than intended.
But here’s the reality today: pilots are watching for this. If any part of the wind profile looks unstable, they will initiate a go-around before even getting close. And if the event occurs too suddenly for avoidance, the aircraft’s systems alert them, and they execute the escape manoeuvre. The engines are pushed to maximum power. The pitch is increased. Configuration is optimised for climb. And because these jets have significant thrust margins—even when fully loaded—they can climb out of a windshear zone safely and effectively. All of this can happen in seconds. It’s what the aircraft is designed to do.
Now let’s address a more difficult question: have windshear and microbursts caused crashes in the past? Yes—but almost exclusively in the 1970s and 1980s, before the technology and training we now take for granted existed. The most cited case is the 1985 crash of Delta Flight 191 in Dallas, where a microburst during landing led to a loss of control. That tragedy, and a few others in that era, served as the turning point. In response, aviation authorities worldwide implemented a complete overhaul of windshear detection, training, and response procedures. The result? Wind shear-related accidents have dropped to near-zero levels in commercial aviation over the last three decades. It’s not that windshear stopped happening—it’s that aviation learned how to predict and beat it.
You may also wonder about how much warning time pilots really get. After all, the idea of a sudden burst of wind doesn’t sound like something that allows for much reaction. But because aircraft performance is now fully modelled for all phases of flight—including how much climb performance is available at maximum weight, maximum thrust, and in abnormal wind conditions—pilots always have a buffer. Minimum climb gradients, terrain clearance, and missed approach procedures are all designed with windshear risk in mind. In other words, your flight isn’t simply hoping for good weather. It’s built to handle the edge cases, and then some.
Also worth noting is that windshear escape procedures are standardised globally. Whether you’re flying in Tokyo, Johannesburg, London, or São Paulo, the principles are the same. This uniformity means that pilots can fly with confidence no matter the region or weather variability. And because aircraft types share similar escape logic—apply full thrust, optimise pitch, maintain control—pilots transition smoothly between simulators and aircraft models while carrying this training throughout.
Another thing passengers often don’t realise is that go-arounds or delayed landings due to windshear are not unusual, and they are not emergencies. They are considered safe, expected, and fully briefed operational decisions. If a storm cell moves close to an airport and causes shifting winds or downdrafts, ATC will notify the pilots, who may decide to wait in a holding pattern or land elsewhere. You may not know why your flight diverted to another city or circled for 20 minutes, but the reason is usually weather-related, and the delay reflects caution—not crisis.
Even if a gust causes a brief bump or motion during landing, this is not a sign of trouble. Aircraft are designed to touch down at speed, absorb vertical forces, and correct small deviations in flight path. The sensations may feel more dramatic than they are, especially when you can see the runway from the window. But the flight deck sees the wind trend, the radar return, and the escape routes—and they are always several steps ahead of what you feel.
Let’s talk briefly about automation. Some passengers fear that windshear conditions require split-second decisions that a pilot might not have time to make. But the truth is, modern aircraft are full of safeguards. While windshear avoidance is a human-piloted manoeuvre, the aircraft’s sensors, warnings, and flight envelope protections are all in place to prevent pilot error. And because the escape manoeuvre is practised so frequently, the pilot’s response is fast, decisive, and often pre-emptive. The systems and the human work together—not against each other.
The final piece of reassurance lies in how often this topic is reviewed behind the scenes. Airlines track weather data continuously. Aircraft automatically report windshear events to maintenance control and airline operations. Airports log and analyse shear events to improve local forecasting. Meteorological tools generate high-resolution models of wind patterns near terrain. In short, windshear is not a mysterious or forgotten threat. It is one of the most studied, prepared-for phenomena in aviation today.
So, can windshear or microbursts cause crashes? The answer is this: they did, decades ago. But today, they are events that pilots and aircraft are actively designed to overcome. The skies haven’t changed much. But aviation has. You’re flying in an era where what once posed a serious threat is now neutralised by awareness, technology, and decades of experience.
You may still feel nervous when the plane shifts slightly near the ground. That’s normal. But beneath your feet is an aircraft that’s been tested for these very conditions. At the front of the plane are pilots who’ve trained for them. And around your flight are systems designed to ensure no decision is left to chance.
You’re not flying blind into unpredictable wind. You’re flying through a known atmosphere, with known responses, and a known outcome—safe arrival.
