What are the primary considerations when selecting electric cable size?

Length and weight

Color and texture

Current carrying capacity and allowable voltage drop

When selecting electric cable size for aircraft applications, the primary considerations are current carrying capacity and allowable voltage drop. This is crucial to ensure that the cable can safely conduct the required current without overheating or voltage drop beyond acceptable limits. Considering the length of the cable is important to account for resistance, which affects current carrying capacity and voltage drop. The weight of the cable is also a factor but not as critical as current carrying capacity and voltage drop. Options B and D, color, texture, flexibility, and durability, are not primary considerations when selecting electric cable size for aircraft applications.
