The NTSB cautioned that “circling approaches can be riskier than other types of approaches,” noting that they “often require maneuvering at low altitude and low airspeed during the final segment of the approach, increasing the opportunity for loss of control or collision with terrain.” It further stated that the risks are “heightened when conducting circling approaches in marginal or reduced visibility conditions.” The NTSB noted that there have been 10 accidents involving circling approaches between 2008 and 2023, resulting in the publication of a Safety Alert last March titled “Circling Approaches: Know the Risks” (PDF).
