Parking on the Boeing 777, also known as PKG, refers to the process of securing the aircraft after it has landed and ensuring its safe storage. When an aircraft is parked, it is no longer in active use and remains stationary until it is ready for its next flight. Proper parking procedures are crucial to maintain the aircraft’s integrity, prevent damage, and ensure the safety of passengers and crew.
In this article, we will explore the importance of parking on the Boeing 777, the necessary steps involved in the process, and the specific considerations taken to ensure the aircraft’s stability and protection.

The Importance of Parking on Boeing 777
Parking is a critical aspect of aircraft operations, and it plays a significant role in maintaining the airworthiness and longevity of the Boeing 777. When an aircraft is parked, it is exposed to environmental factors that can potentially impact its structural integrity and components. By implementing proper parking procedures, such as selecting suitable parking spots and securing the aircraft correctly, potential risks and damages can be minimized.
One of the primary reasons for emphasizing proper parking on Boeing 777 is to prevent unnecessary wear and tear on the aircraft’s tires. When an aircraft is stationary, the tires can develop flat spots due to the weight exerted on them. These flat spots may cause vibrations and uneven tire wear during future takeoffs and landings. To mitigate this issue, aircraft operators ensure that the weight of the aircraft is evenly distributed on all tires during parking, reducing the likelihood of flat spots.
Selecting an Appropriate Parking Spot
Choosing the right parking spot for the Boeing 777 is crucial to ensure its safety and accessibility. Here are some factors considered when selecting a suitable parking location:
- The parking area should have adequate space to accommodate the aircraft’s dimensions, including its wingspan and length.
- The surface of the parking spot should be strong enough to support the weight of the aircraft and prevent sinking or uneven settling.
- Proximity to service areas and facilities is essential to facilitate maintenance and inspections during the aircraft’s parked state.
Moreover, the parking spot should be away from potential hazards, such as construction activities, wildlife, or other aircraft traffic. Additionally, the spot should provide easy access to essential utilities, such as power supply, fueling stations, and ground support equipment. These considerations help ensure the efficient operation and turnaround of the aircraft when it is ready to resume active service.
Securing the Aircraft During Parking
Once the Boeing 777 is in its designated parking spot, various measures are taken to secure the aircraft. These include:
- Chocking the wheels: Wheel chocks, which are wedges placed in front of and behind the aircraft’s tires, prevent any movement or rolling during parking. They play a crucial role in ensuring the aircraft remains stationary and cannot be unintentionally moved, especially during high winds or uneven ground conditions.
- Applying parking brakes: Engaging the parking brakes helps provide an additional layer of security by preventing the aircraft’s wheels from rotating. This reduces the risk of accidental movement or unintended aircraft displacement.
- Securing doors and hatches: All doors, hatches, and access panels are properly closed and latched, ensuring they remain secure during the parked state. This prevents unauthorized access and helps maintain the structural integrity of the aircraft.
Additionally, airlines and ground handling personnel perform regular inspections of the parked aircraft to ensure its overall condition and detect any signs of damage or potential issues. These inspections include visually examining the exterior and interior of the aircraft, checking for leaks, and verifying the proper functioning of essential systems.
Protection from Environmental Factors
The Boeing 777 is exposed to various environmental factors when parked, including weather conditions, temperature fluctuations, and debris. To protect the aircraft from these elements, several measures are taken:
- Shielding the aircraft: Aircraft protective covers, made from durable materials, are used to shield the parked aircraft from direct sunlight, rain, snow, and other environmental elements. These covers provide an additional layer of protection, preventing potential damage to critical exterior components and reducing the need for frequent cleaning and maintenance.
- Avoiding stagnant water: Proper drainage systems are implemented in the parking areas to prevent stagnant water from collecting around the aircraft. Stagnant water can lead to corrosion, electrical issues, and damage to various aircraft systems.
- Dust and debris management: Regular cleaning and maintenance practices are undertaken to remove dust, dirt, and debris from the parked aircraft. These foreign particles, if left unattended, can cause abrasion, clog ventilation systems, and potentially affect the aircraft’s overall performance.
By implementing protective measures, airlines ensure that the Boeing 777 remains in optimal condition during its parked state, reducing the risk of unnecessary repairs and extending its overall lifespan.
Conclusion
Parking on the Boeing 777 is a vital activity that ensures the aircraft’s safety, integrity, and proper preservation when not in active use. By selecting appropriate parking spots, securing the aircraft correctly, and implementing protective measures, potential damage and risks are minimized. The careful attention given to parking procedures contributes to the efficient operation, maintenance, and long-term performance of the Boeing 777, ensuring a safe and reliable flying experience for passengers and crew.
