The landing patterns have not changed. However, the FAA recently updated arrival and departure routes to most airports in South Florida through a process called the Metroplex, despite the Airport Authority’s objections and requests for additional review and public outreach.
The routes that were redesigned due to the Metroplex are generally further away from the airport as the aircraft makes its way toward the final approach path or after initial departure. During these phases of flight, the aircraft is normally higher than when on the final approach or initial departure paths which have remained unchanged.
