第五级(Level V)
Level V is an advanced level of proficiency and completion of this level takes the pilot to the level of a pilot capable of performing beyond the basics of Backward Flight. Intrinsic to this level is successfully completing all components of the previous levels, then advancing to the ability to control the helicopter in these new orientations. Please use extreme caution when performing these advanced maneuvers, the pilots and spectators safety is of utmost importance.
第五级属於高级程度，使操控者有能力执行基础的後退飞行。第五级的本质是要能成功地完成前四级的所有动作，以及增进对於新动作的操控及定位能力。在执行这些高级的动作时，必须尽可能地注意操控者及观众的安全。
