In aviation, "ad hoc" refers to a situation or task that is created or arranged for a specific purpose, usually in response to an unexpected circumstance or request. For example, an ad hoc flight may be arranged to transport urgent medical supplies or personnel to a remote location, or an ad hoc meeting may be called to discuss an unexpected issue related to a flight or aircraft. The term "ad hoc" is used to emphasize the temporary or impromptu nature of the situation or task.
