混合FLIGHTPLAN(VFR和IFR)

AIM 5-1-7. Composite Flight Plan (VFR/IFR Flights)
a. Flight plans which specify VFR operation for one portion of a flight, and IFR for another portion, will be accepted by the FSS at the point of departure. If VFR flight is conducted for the first portion of the flight, pilots should report their departure time to the FSS with whom the VFR/IFR flight plan was filed; and, subsequently, close the VFR portion and request ATC clearance from the FSS nearest the point at which change from VFR to IFR is proposed. Regardless of the type facility you are communicating with (FSS, center, or tower), it is the pilot’s responsibility to request that facility to “CLOSE VFR FLIGHT PLAN.” The pilot must remain in VFR weather conditions until operating in accordance with the IFR clearance.

b. When a flight plan indicates IFR for the first portion of flight and VFR for the latter portion, the pilot will normally be cleared to the point at which the change is proposed. After reporting over the clearance limit and not desiring further IFR clearance, the pilot should advise ATC to cancel the IFR portion of the flight plan. Then, the pilot should contact the nearest FSS to activate the VFR portion of the flight plan. If the pilot desires to continue the IFR flight plan beyond the clearance limit, the pilot should contact ATC at least 5 minutes prior to the clearance limit and request further IFR clearance. If the requested clearance is not received prior to reaching the clearance limit fix, the pilot will be expected to enter into a standard holding pattern on the radial or course to the fix unless a holding pattern for the clearance limit fix is depicted on a U.S. Government or commercially produced (meeting FAA requirements) low or high altitude enroute, area or STAR chart. In this case the pilot will hold according to the depicted pattern.

a. 先VFR后IFR的情况下,飞行员要求联系FSS告知起飞时间,然后再转换点联系要求关闭VFR并向ATC申请IFR。不管通过哪种途径,都是飞行员有责任要求关闭VFR。飞行员必须留在VFR的天气标准中,直到申请到IFR。

b. 先IFR后VFR的情况下,飞行员会被放行到转换点,飞行员联系ATC取消IFR部分计划,并联系最近的FSS启动VFR计划。如果飞行员想继续IFR飞行,则飞行员要在IFR结束前5分钟向ATC申请。如果申请没有得到回复则在最后一个点进入标准等待,或者这个点要求的等待方式。
