The expression "on standby" means to be ready and waiting for something to happen. It is commonly used when referring to people or things that are prepared to take action, but have not yet been called upon to do so. For example, a pilot may be "on standby" for a flight, meaning that they are available to fly if needed, but are not currently scheduled for a specific flight. It can also be used in everyday language, such as saying "I'm on standby to help with anything you need."
