Imagine yourself sitting in a plane, all set to take off, when suddenly you hear the engines powering down and the aircraft coming to a sudden stop on the runway. What just happened? Well, it’s likely that the pilots decided to abort the takeoff for safety reasons.
Takeoffs are one of the most critical phases of any flight. They require a significant amount of skill, precision, and attention to detail from the pilots. But what happens when something goes wrong during takeoff, and the pilots decide to abort the takeoff? In this blog post, we will discuss the reasons why pilots abort a takeoff and the importance of safety in aviation.
First, it’s essential to understand what an aborted takeoff is. An aborted takeoff, also known as a rejected takeoff, is when the pilots decide to stop the aircraft before it takes off.
Understanding a Takeoff
During the takeoff, the aircraft is accelerating to gain enough speed to lift off the ground. However, there are situations where a pilot might need to abort a takeoff. In fact, there are three distinct phases of a takeoff where a pilot might choose to abort the takeoff.
The first phase of a takeoff is the low-speed regime, which is typically below 80 knots. During this phase, even minor failures can cause a pilot to reject the takeoff. This is done to avoid any potential accidents or issues that could arise from continuing the takeoff.
In the second phase of a takeoff, known as the high-speed regime, the aircraft is usually accelerating above 80 knots but still below V1. During this phase, minor problems may be ignored, but if there are serious problems, such as engine failures, the pilot will still choose to abort the takeoff.
The third and final phase of a takeoff is above V1, which is the takeoff decision speed. V1 is calculated before each flight for larger multi-engine airplanes. Above the decision speed, the aircraft may overshoot the runway if the takeoff is aborted. Therefore, a rejected takeoff is not normally performed above this speed unless there is reason to doubt the aircraft’s ability to fly.
However, if a serious failure occurs or is suspected above V1, but the aircraft’s ability to fly is not in doubt, the takeoff will continue despite the suspected failure. The aircraft will attempt to land again as soon as possible. On the other hand, if the aircraft’s ability to fly is in doubt, such as in the event of a major flight-control failure, the best option may be to reject the takeoff, even if after V1, accepting the likelihood of a runway overrun.
Some Reasons Why Pilots Abort a Takeoff
Technical Issues: One of the most common reasons for an aborted takeoff is technical issues with the aircraft. These issues can range from a warning light indicating a malfunction to a more serious problem that could jeopardize the safety of the flight. Pilots are trained to detect and respond to these issues quickly, and if they deem it necessary, they will abort the takeoff.
Weather Conditions: Weather conditions can also be a reason for an aborted takeoff. Strong winds, heavy rain, or low visibility can make takeoff unsafe. Pilots have access to weather reports and will assess the conditions before takeoff. If they determine that the weather is not suitable for takeoff, they will abort.
Windshear: Windshear is a sudden and drastic change in wind speed or direction that can cause a dangerous condition for aircraft during takeoff, landing, or in-flight. When an aircraft encounters windshear during takeoff, it can result in a sudden loss of lift or airspeed, which can cause the aircraft to stall or descend rapidly. In such cases, the pilot may have to abort the takeoff to avoid a potential crash.
Bird strike: If the plane collides with birds on the runway or during takeoff, it can cause significant damage to the aircraft. In such a scenario, the pilot may decide to abort the takeoff and return to the gate for a safety inspection.
Runway Incursions: Another reason for an aborted takeoff is a runway incursion. A runway incursion is when an aircraft, vehicle, or person enters a runway without authorization. This can cause a collision with the aircraft taking off or landing, which could be catastrophic. Pilots are trained to be aware of runway incursions and will abort the takeoff if they see a potential danger.
Unsecured Cargo: If the cargo onboard the aircraft is not secured correctly, it can shift during takeoff, causing an imbalance in the aircraft’s weight distribution. This can lead to loss of control, which could result in a crash. Pilots will abort the takeoff if they suspect that the cargo is not secured properly.
Pilot Error: Pilot error is another reason why a takeoff may be aborted. If the pilots make a mistake during the takeoff, such as applying too much or too little power, they may decide to abort. It’s better to stop the aircraft on the ground and reassess the situation than to continue with a potentially dangerous takeoff.
When it comes to taking off, safety is the top priority for pilots. That’s why there are several reasons why they might choose to abort a takeoff, all of which are designed to ensure the safety of everyone on board. While the specific procedures for aborting a takeoff may vary depending on factors like the type of aircraft, airline, and country, the decision to abort is always made with safety in mind.
Aborted takeoffs are not common, but they do happen. Pilots are trained to handle these situations and prioritize safety over everything else. The decision to abort a takeoff is never taken lightly and is based on a careful assessment of the situation. As passengers, we should trust the pilots’ expertise and appreciate their commitment to safety. By understanding the reasons behind aborted takeoffs, we can appreciate the importance of safety in aviation and have a greater appreciation for the pilots who keep us safe in the skies.
