A weather briefing provided for information requested 6 or more hours in advance is known as what?

An outlook briefing is the correct term for a weather briefing that is provided when information is requested six or more hours in advance of a flight. This type of briefing focuses on providing an overview of expected weather conditions over an extended period, allowing pilots to make informed decisions about their upcoming flights.

Outlook briefings often include information on significant weather phenomena, trends, and anticipated developments that may affect the flight. It differs from other types of briefings that are typically more detailed and time-sensitive, designed to provide immediate weather conditions and forecasts closer to the departure time. Thus, when a pilot seeks weather information well ahead of time, the outlook briefing helps in planning and ensuring safety relative to anticipated weather changes.
