第四级(Level IV)
Level IV is an advanced level of proficiency and completion of this level takes the pilot to the level of a pilot capable of performing the beyond the basics of Inverted 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.
第四级属於高级程度,使操控者有能力执行基础的倒飞动作。第四级的本质是要能成功地完成前三级的所有动作,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。
