What does "Cleared to Engage" allow aircraft or flight to do?

The term "Cleared to Engage" is a directive commonly used in military aviation that permits an aircraft or flight to attack a specified target. This authorization is typically issued by a command element or fire control and is based on the assessment that the target meets the engagement criteria set forth, such as rules of engagement and target identification.

In this context, the phrase indicates that the flight has the necessary clearance to conduct offensive operations against identified targets within the scope of their prescribed parameters. These parameters might include factors such as time, distance, and weapons systems to be employed, ensuring that the engagement is lawful and tactically sound.

The other choices do not represent the meaning of "Cleared to Engage." Requesting further information pertains to situational awareness but does not imply direct action. Taking evasive action relates to defensive maneuvers, not offensive engagement. Changing altitude, while a potential maneuver, does not directly correlate with the authorization to engage a target. Therefore, option B accurately captures the essence and intent behind the phrase "Cleared to Engage" in military aviation operations.
