What is the recommended action if the brake temperature exceeds the limit?

The recommended action when brake temperature exceeds the limit is to wait for it to cool down. This is important because high brake temperatures can lead to reduced effectiveness, potential brake failure, or even fire hazards. By allowing the brakes to cool, you can ensure that they return to a safe operating temperature, which is critical for maintaining safe operation during subsequent taxi or landing phases.

In practice, when operating an aircraft like the Falcon 7X, pilots are trained to monitor brake temperatures closely. If any signs of overheating are observed, the prudent course of action is to cease operations so that the brakes can cool naturally. It's preferable to wait rather than continue operation with the potential risk of brake malfunction, as doing so can compromise safety.

The other options, such as activating cooling systems or requiring an immediate landing, may not be appropriate or feasible in all situations. Depending on the malfunction or issue at hand, activating cooling systems might not be available or effective enough, while an immediate landing could lead to unnecessary risks if the situation doesn't warrant such a drastic response. Thus, letting the brakes cool is often the most effective and safest approach.
