Which factor is essential when selecting the correct weight of textile fabric for aircraft covering?

The essential factor when selecting the correct weight of textile fabric for aircraft covering is the manufacturer's recommendation. Each aircraft has specific requirements based on its design, intended use, and performance characteristics. The manufacturer specifies the appropriate fabric weight to ensure that the covering provides the necessary strength, durability, and aerodynamic properties.

While factors like the aircraft's Vne (never exceed speed) may influence the overall design and safety considerations, it is ultimately the manufacturer's guidelines that will ensure compliance with safety standards and performance expectations. The color of the fabric and its cost are secondary considerations that do not impact the fabric's structural integrity or suitability for covering. Considering only the manufacturer's recommendations helps ensure safe and effective aircraft operation.
