The sound of a plane landing is a familiar and comforting one, but have you ever stopped to think about how it actually comes to a stop? The process of braking a plane is a complex and fascinating one, involving a combination of technology, engineering, and human expertise. In this article, we’ll delve into the world of aviation and explore the different ways in which planes brake when landing.

The Importance of Braking
Braking is a critical phase of flight, as it requires the pilot to carefully control the plane’s speed and direction in order to bring it safely to a stop. This is especially important during landing, as the plane is traveling at a high speed and must be slowed down quickly and smoothly in order to avoid any potential hazards. The importance of braking cannot be overstated, as it is a crucial component of safe and successful flight.
The Different Types of Braking Systems
There are several different types of braking systems used in commercial aircraft, each with its own unique characteristics and advantages. Some of the most common types of braking systems include:
| Type | Description |
|---|---|
| Thrust Reversers | Thrust reversers are a type of braking system that use the plane’s engines to slow it down. They work by redirecting the engine’s thrust backwards, creating a braking effect. |
| Brake Pads | Brake pads are a type of braking system that use friction to slow down the plane. They are typically made of a heat-resistant material and are designed to withstand the high temperatures generated during braking. |
| Antiskid Systems | Antiskid systems are a type of braking system that use sensors and computer controls to monitor the plane’s speed and braking performance. They are designed to prevent the plane from skidding or locking up during braking. |
How Thrust Reversers Work
Thrust reversers are a type of braking system that use the plane’s engines to slow it down. They work by redirecting the engine’s thrust backwards, creating a braking effect. This is achieved through a complex system of valves, actuators, and ducting that allows the engine’s thrust to be redirected.
Here’s a step-by-step explanation of how thrust reversers work:
- The pilot activates the thrust reverser by flipping a switch.
- The switch sends an electrical signal to the engine’s electronic control unit (ECU).
- The ECU receives the signal and sends a command to the thrust reverser’s actuator.
- The actuator opens the thrust reverser’s valves, allowing the engine’s exhaust gases to flow backwards.
- The exhaust gases are then redirected through a ducting system, which channels them out of the back of the plane.
- The redirected thrust creates a braking effect, slowing down the plane.
How Brake Pads Work
Brake pads are a type of braking system that use friction to slow down the plane. They are typically made of a heat-resistant material and are designed to withstand the high temperatures generated during braking. (See Also: How to Bleed the Brake System? A Step-by-Step Guide)
Here’s a step-by-step explanation of how brake pads work:
- The pilot activates the brake by pressing the brake pedal.
- The brake pedal sends a signal to the brake master cylinder.
- The master cylinder receives the signal and sends hydraulic fluid to the brake calipers.
- The brake calipers receive the hydraulic fluid and use it to apply pressure to the brake pads.
- The brake pads then make contact with the plane’s wheels, creating friction and slowing down the plane.
How Antiskid Systems Work
Antiskid systems are a type of braking system that use sensors and computer controls to monitor the plane’s speed and braking performance. They are designed to prevent the plane from skidding or locking up during braking.
Here’s a step-by-step explanation of how antiskid systems work:
- The antiskid system uses sensors to monitor the plane’s speed and braking performance.
- The sensors send the data to the antiskid computer, which analyzes it and determines if the plane is at risk of skidding or locking up.
- If the computer detects a risk of skidding or locking up, it sends a signal to the brake calipers to adjust the braking pressure.
- The brake calipers receive the signal and adjust the braking pressure to prevent skidding or locking up.
Conclusion

FAQs
Q: How do planes brake when landing?
A: Planes use a combination of thrust reversers, brake pads, and antiskid systems to brake when landing. The specific system used depends on the type of aircraft and the conditions of the landing.
Q: What is the purpose of thrust reversers?
A: The purpose of thrust reversers is to redirect the engine’s thrust backwards, creating a braking effect. This helps to slow down the plane during landing.
Q: How do brake pads work?
A: Brake pads work by applying friction to the plane’s wheels, slowing down the plane. They are typically made of a heat-resistant material and are designed to withstand the high temperatures generated during braking.
Q: What is the purpose of antiskid systems?
A: The purpose of antiskid systems is to prevent the plane from skidding or locking up during braking. They use sensors and computer controls to monitor the plane’s speed and braking performance, adjusting the braking pressure as needed to prevent skidding or locking up.
