Which of the following should be avoided with respect to raised webbed barriers with a T-6?

Engaging the barrier is a critical action to avoid when dealing with raised webbed barriers and T-6 aircraft. Engaging the barrier typically means making contact with it, which can lead to significant damage to the aircraft as well as potential injuries to the occupants. Raised barriers are designed to prevent unauthorized access to certain areas and to mitigate risks during operations. Contacting such barriers can cause the aircraft to become uncontrollable, potentially resulting in crashes or further accidents.

While taxiing along the barrier, landing near the barrier, and turning away from the barrier involve maneuvering in proximity to the barrier and should be done with caution, they do not inherently involve the risk of direct contact that engaging the barrier does. Therefore, it is crucial to ensure that the aircraft avoids any direct interaction with the barrier itself to maintain safety and operational integrity.
