In non-radar operations, what is the required departure divergence angle?

In non-radar operations, the required departure divergence angle is 45 degrees. This angle is essential for ensuring sufficient lateral separation between departing aircraft, especially when they are taking off from the same airport. By using a 45-degree divergence angle, air traffic control can help to minimize the risk of collisions and ensure that the aircraft are safely spaced apart as they climb out. When aircraft are departing close together, a divergence angle of this size allows for a safe separation distance that accounts for the performance capabilities of different aircraft and atmospheric conditions. It supports effective separation in the absence of radar surveillance, necessitating more precise calculations and planning to maintain safety. A divergence angle of 30 degrees would not provide sufficient lateral distance, particularly in the early stages of flight when aircraft are still within proximity of the airport. Similarly, larger divergence angles, such as 60 or 90 degrees, would result in inefficient airspace usage, leading to a waste of air traffic capacity. Thus, 45 degrees strikes an optimal balance between safety and efficiency in non-radar environments.
