What is the standard aviation wood?

The standard aviation wood is Sitka spruce, and this is due to its unique combination of properties that make it particularly suitable for aircraft construction. Sitka spruce is known for its excellent strength-to-weight ratio, which is crucial in aviation as it ensures that the aircraft remains lightweight while maintaining structural integrity. This wood also has favorable acoustic properties, making it ideal for areas where vibrations and sound are a consideration.

Additionally, Sitka spruce has good workability and durability, meaning it can be easily machined and is less likely to warp or split over time, which is essential for maintaining the performance and safety standards required in aviation. Its straight grain and uniform texture further enhance its appeal for aircraft components, including wings and fuselage.

While other woods like Douglas fir, pine, and birch are also used in various applications, they do not offer the same superior qualities that Sitka spruce provides, particularly in terms of overall weight and strength for aviation purposes. Therefore, Sitka spruce is predominantly regarded as the standard wood used in aviation.
