Which factors primarily determine the weight of textile fabric used in aircraft covering?

The weight of textile fabric used in aircraft covering is primarily influenced by the speed of the aircraft and the maximum wing loading. Aircraft are designed to endure specific aerodynamic forces and loads during flight, which directly affects the choice of materials used for covering.

For faster aircraft, the fabric must possess qualities that can withstand higher stresses and strains due to increased air resistance and lift forces. This necessitates the use of heavier or more durable materials to ensure structural integrity and safety. Similarly, maximum wing loading is a critical factor in determining the strength requirements of the fabric. High wing loading typically means the wings need to support more weight relative to their area, thus requiring fabric that not only meets strength requirements but also maintains a low overall weight to enhance performance and efficiency.

In contrast, factors such as cost, availability, color, texture, manufacturer, and model type may influence material selection but do not fundamentally determine the weight of the fabric in relation to structural and aerodynamic needs.
