How far should aircraft maintain separation during VFR departures?

During Visual Flight Rules (VFR) departures, aircraft are required to maintain a vertical separation of at least 1000 feet from other aircraft operating in controlled airspace. This standard helps ensure safe traffic management and reduces the risk of mid-air collisions, especially in areas where multiple aircraft may be departing or arriving in proximity to each other. The 1000-foot separation is a widely recognized and established rule in aviation to keep aircraft adequately spaced apart during their ascent or descent, fostering a safer flying environment for everyone involved.
