What is an abbreviated briefing?

The term "abbreviated briefing" refers to a scenario where pilots request additional information about specific aspects of their flight. This type of briefing is usually shorter than a full briefing and focuses on the specific details the pilot wants to know rather than covering all aspects of flight planning. Such a briefing can include updates on weather, airspace information, and other relevant factors that may affect the flight, but it does so in a more concise manner, allowing the pilot to efficiently obtain the details they need.

In most operational situations, pilots may already have a good understanding of the flight environment or may not need extensive information for every flight, particularly if it's routine. Hence, this fits well with the definition of an abbreviated briefing.
