Definition
A structured discussion conducted before a flight in which the pilot in command reviews the planned operation, including route, weather, fuel, performance, expected procedures, emergency actions, and crew or passenger responsibilities, so that everyone on board knows what to expect and what to do if something goes wrong.
Plain English
A talk-through before takeoff that covers what the flight will look like, what could go wrong, and who does what if it does.
Context Anchor
You will encounter this before a training flight, especially when an instructor explains the lesson plan, safety items, and responsibilities before going to the airplane.
Derivation
Pre- means before, and 'briefing' comes from the military sense of giving someone a short, focused set of instructions before a mission. The aviation use carries that same idea: a short, deliberate review before action.
Why Pilots Care
Ensures all occupants know how to respond in an emergency, fulfilling regulatory requirements and reducing risk during critical phases of flight.
Intuition Check
Do not think of a preflight briefing as only paperwork or a quick reminder. In aviation, it is a deliberate safety discussion before the flight so the plan and responses are clear before the airplane moves.
Example Sentence 1
During the preflight briefing, the instructor reviewed what each pilot would do if an engine failed before reaching liftoff speed.
Example Sentence 2
In multiengine training, the instructor evaluated the student’s preflight briefing for completeness and clarity.
