How long should one typically wait before attempting to approach hot brakes?

Waiting before approaching hot brakes is a critical safety procedure to prevent injury from the intense heat and potential for brake failure. The correct time to wait is typically around 30 minutes. This duration allows the heat generated during a landing or a hard braking event to dissipate significantly, reducing the risk of burns or ignition of flammable materials.

During this 30-minute interval, it's important to allow the brakes to cool down adequately. Direct exposure to hot brakes can cause severe burns, and failing to wait the recommended time could result in unsafe conditions for personnel approaching the aircraft.

In aviation, understanding the specifics of brake operation and the chemistry of braking materials is essential. Different aircraft might have variations, and pilots are trained to recognize the signs of overheating and to know manufacturer guidelines and standard operating procedures, which typically recommend a 30-minute wait for safety.
