When is Type 1 control used in air strikes?

Type 1 control is utilized in air strikes specifically when the attacking aircraft must be visually acquired alongside the target. This form of control is implemented to ensure that the pilot can visually confirm both the target and the aircraft's positioning before executing an attack. This creates a high level of situational awareness and safety, as it allows the pilot to confirm the target's identity and ensure that there are no friendlies in the area before striking.

The requirement for visual acquisition means that this control method is typically applied in situations where precision is critical, and the risk of collateral damage must be minimized. It reflects a higher level of control and scrutiny over the engagement process, thus facilitating a more accurate and deliberate attack on the target.

In contrast, the other options involve conditions that do not align with the requirements of Type 1 control—such as scenarios where targets might be engaged without visual confirmation or when visual acquisition is not feasible, such as in low-visibility conditions or when multiple attacks are planned that do not necessitate visual oversight.
