What is the significance of the 90-degree approach angle for helicopters?

The 90-degree approach angle for helicopters is significant because it represents the safest approach for landings and takeoffs. Approaching at this angle allows pilots to maintain a clear view of potential obstacles on the ground and facilitates better situational awareness. This angle also helps pilots in managing their descent and aligning with the landing zone while reducing the risk of sudden maneuvers that could compromise safety.

Using a 90-degree angle also aids in establishing a stable approach profile, essential for ensuring smooth landings. While other angles may have their advantages in specific scenarios, the 90-degree approach is designed with safety as a priority, providing the most consistent and secure framework for helicopter operations.
