Price: $24.95

Best of: Innovative chocks

The Avid Labs wheel chock system are innovative wheel chocks, which use the weight of the wheel to their advantage. The solid rubber chocks are connected by a heavy-duty polyester rope. The open side of each chock has an extra channel for the rope to slip into, which allows the user to cinch the chocks tightly to the wheel. The weight on the chock then constricts the rope, making the chocks rock solid. One pair is needed for each wheel.

When choosing aircraft chocks, several factors must be considered to ensure the safety of the aircraft and reliability of the chocks.

Different chocks are designed for specific aircraft sizes and gross vehicle operating weights.

For instance, larger aircraft with heavier weights require sturdier, more robust chocks made from materials such as rubber or aluminum, which can withstand the immense pressure exerted by the aircraft wheels.

Smaller aircraft, on the other hand, can utilize lighter chocks, such as those made from plastic, which are easier to handle and store.

When selecting aircraft chocks, it is vital to consider the size and type of wheels on the aircraft. The size of the wheels helps determine the right chock dimensions to ensure a snug and secure fit.

Different types of wheels, such as radial tires versus bias-ply tires, may also influence the choice of chock material and design. For instance, chocks with a concave surface or additional grip features can provide enhanced contact and stability for radial tires.

Lastly, for aircraft with a low wheel pant clearance, consider the height from the ground to the wheel fairing to ensure the chocks can fit snugly around each tire.

The type of ground on which the chocks will be used is a crucial factor to consider when selecting aircraft chocks.

Chocks used on soft ground should have a wider base or additional grip, preventing them from sinking into the surface and ensuring they maintain their position. While standard rubber or plastic chocks often provide sufficient grip and stability on hard or paved ramps.

Additionally, chocks with enhanced traction features or those designed with flexibility in mind can offer greater performance on uneven terrain (e.g., uphill, downhill).

Frequent use demands chocks that can withstand continuous pressure and harsh environments without deteriorating.

Look for materials such as rubber or aluminum, which are known for their long-lasting durability.

Additionally, ease of use becomes crucial as it reduces the effort and time required to secure the aircraft, particularly in high-turnover situations where quick and efficient operations are needed.

Higher-priced chocks often offer advanced features, enhanced durability, and are made from premium materials such as aluminum, which provides exceptional corrosion resistance.

However, less expensive options, such as plastic or rubber chocks, can still be highly effective for many general aviation needs, particularly if you are looking for lightweight and easily transportable solutions.

While it is important to find chocks within your budget, remember that investing in durable, high-quality chocks can save you money and prevent accidents in the long run by reducing the need for frequent replacements.

To ensure the safety and security of an aircraft, it is essential to consider the following tips for chock use.

Proper installation and usage of aircraft chocks are crucial to ensuring the safety and stability of the aircraft while it is parked.

Strictly follow the manufacturer's instructions, as different chocks may have specific requirements or best practices for optimal performance.

Position the chocks in front of and behind each wheel of the aircraft to prevent any forward or backward movement. Ensure the chocks fit snugly against the tires, making full contact with the wheel surface.

Inspecting wheel chocks regularly is crucial to ensure their effectiveness and longevity.

Check for wear, damage, or loose components that could compromise their performance. Over time, exposure to the elements, such as UV rays, moisture, and extreme temperatures, can cause material degradation.

Inspect the chocks for cracks, brittleness, and significant loss of original shape that might indicate they are no longer safe to use. Additionally, examine the ropes and fastenings for fraying, splits, or other signs of wear and tear.

For added safety, use multiple chocks to prevent the aircraft from moving, covering both front and rear wheels.

In addition to using chocks, use tiedowns or other safety devices to enhance aircraft safety. Tiedowns are essential, especially in windy conditions, as they provide extra stability by securing the aircraft to the ground.

Other complementary safety measures, such as wheel locks and brake systems, can also be employed to ensure the aircraft remains stationary.

Proper placement of chocks is crucial to ensuring the safety and stability of the aircraft.

Ensure chocks are placed correctly under the wheels to prevent movement by positioning them snugly against the forward and aft sides of the tires. This method creates a secure barrier that prevents rolling, even on sloped or uneven ground.

After placement, apply gentle pressure to verify the chocks are stable and will not dislodge easily.

When choosing aircraft chocks, it is crucial to conduct thorough research to ensure you select the most suitable option for your specific needs.

Given the diversity of aircraft types and operating environments, not all chocks are created equal. Make sure to consider factors such as the gross vehicle operating weight and type of aircraft, the typical ground conditions where the aircraft will be parked, and how often the chocks will be used before making your final selection.

We hope our comprehensive guide has helped you narrow down the wheel chocks appropriate for your specific aircraft.

How do I choose wheel chocks?

First, assess the type and weight of the vehicle (i.e. aircraft). Next, examine the wheel configuration and number of wheels on your aircraft, as this will determine whether you need multiple chocks or specific chock designs to secure your aircraft effectively. Consider the ground conditions where your aircraft will be parked and think about how often you will use the chocks. Lastly, remain mindful of your budget, as prices for aircraft chocks can vary significantly, and investing in higher-quality chocks may provide better long-term value.

What size wheel chocks do I need?

The size of wheel chocks you need is dependent on several factors, including the type and weight of your aircraft, as well as the wheel size and configuration. For light aircraft, smaller chocks such as plastic or low-profile rubber chocks are often sufficient. For heavier aircraft or those with larger wheels, there are more robust options, such as rubber or aluminum chocks.

What wheel chocks do I need?

For smaller, lightweight aircraft, plastic or low-profile rubber wheel chocks are typically sufficient due to their ease of handling and lightweight properties. Larger aircraft, on the other hand, require robust and heavy-duty options such as rubber or aluminum chocks, which can withstand the substantial weight.

What are the requirements for aircraft chocks?

Aircraft chocks must be sturdy and durable, made from materials such as rubber, plastic, aluminum, or rope. These materials should withstand various weather conditions and provide adequate grip on diverse surfaces, such as concrete, asphalt, or dirt. The size of the chocks is also critical, as it should be appropriate for the wheel size and aircraft weight specifications.
