Mixing And Matching VFR and IFR Plans

Key Takeaways:

  • Pilots navigating complex airspaces often face a dilemma: endure cumbersome IFR departures in clear weather or fly VFR with the risk of encountering adverse weather later in the flight.
  • The Aeronautical Information Manual (AIM) provides guidance for "composite flight plans," which allow pilots to combine both VFR and IFR segments within a single flight.
  • For a VFR-first composite plan, pilots must report departure, close the VFR portion, and obtain their IFR clearance at the planned transition point, ensuring visual meteorological conditions until operating on the IFR clearance.
  • For an IFR-first composite, pilots can cancel IFR for the VFR segment or file a formal VFR plan; extending an IFR clearance beyond its limit requires advising ATC at least five minutes prior.

Pilots at my airport in New Jersey sometimes face a dilemma over whether or not to file IFR or go VFR. With the airport nestled just west of New York’s massive Class B airspace, the choreography we need to dance through on an IFR departure can be frustrating — especially when the weather is clear. For example, we often find ourselves pointing the nose in the wrong direction for several miles before finally being funneled toward the infamous Brezy intersection through which almost all northeast-bound IFR flights must pass. So if the weather cooperates, a lot of folks just file VFR and trust to luck for a clearance through the Class B airspace (or fly over it).

The problem is that sometimes weather on the other side can be questionable. And it would be comforting to be on an IFR flight plan, especially when the destination is coastal Cape Cod or the off shore islands Martha’s Vineyard or Nantucket. The Aeronautical Information Manual (section 5-1-7) has guidance on composite flight plans; that is a combination VFR/IFR flight. It says such flight plans will be accepted by the Flight Service Station (FSS) of the departure point. If the VFR portion is first, the pilot should report the time of departure to the FSS with whom the flight plan was filed, then close the VFR portion and request the IFR clearance with the FSS nearest the point where the two flight plans change over. The AIM stresses that it is the pilot’s responsibility to ensure that the VFR flight plan is closed, and that visual meteorological conditions prevail until operating on the IFR clearance.
