Use information provided by such technologies to separate your aircraft from traffic before aggressive, evasive maneuvering is required. Often, slight changes in rate of climb or descent, altitude, or direction can significantly reduce the risk of a midair collision long before the conflicting aircraft has been seen.

The foundational concept for avoiding midair collisions in aviation is "See and Avoid." This principle mandates that regardless of whether a pilot is flying under Visual Flight Rules (VFR) or Instrument Flight Rules (IFR), they have a continuous responsibility to remain vigilant and visually scan the sky for other aircraft. In the modern 2026 airspace, this human-centric concept is heavily augmented by TCAS (Traffic Collision Avoidance System) and ADS-B (Automatic Dependent Surveillance-Broadcast) technology. These systems provide pilots with cockpit displays of surrounding traffic and "Resolution Advisories" (RA), which give automated instructions to climb or descend if a collision is imminent. Pilots are trained to use a systematic scanning technique, moving their eyes in 10-degree increments to overcome the eye's natural tendency to fixate. Even with advanced radar, "See and Avoid" remains the primary legal and practical defense against midair accidents.
