第二级(Level II)
Level II is an intermediate level of proficiency and completion of this level takes the pilot to the level of a well rounded pilot capable of performing Basic Flight skills. Intrinsic to this level is successfully completing all components of Level I, then advancing to the ability to FLY the helicopter in circuits.
第二级属於中等程度，使操控者有能力执行基础飞行的技巧。第二级的本质是要能成功地完成第一级的所有动作，以及增进圆周飞行的能力。
