What must pilots report regarding turbulence?

Pilots are required to report turbulence to help maintain safety and provide valuable information to air traffic control and other pilots. The information that needs to be conveyed includes the pilot's current position, the time of the observation, the altitude at which the turbulence is experienced, and the type of turbulence encountered (e.g., light, moderate, severe). This information is crucial in enabling air traffic controllers to manage air traffic effectively, alert other pilots to potentially hazardous conditions, and make necessary adjustments to flight paths.

Reporting only the altitude would not provide sufficient context for safety, as it doesn't communicate the location or severity of the turbulence, leaving other aircraft unaware of the potential hazard. Reporting weather conditions in the area is also important but does not specifically address turbulence types or their exact impact on flight operations. Discussing the type of aircraft and crew experience might be useful in some contexts, but it does not directly provide actionable information about turbulence that would benefit other aircraft in the vicinity. Therefore, the comprehensive reporting mandated by option B is essential in maintaining safe flight operations amidst varying turbulence conditions.
