Which of the following are key responsibilities of an Aircraft Dispatcher during flight planning?

An Aircraft Dispatcher's key responsibilities during flight planning include calculating weight and balance and optimizing routes, which are essential tasks that ensure the safety and efficiency of the flight.

Weight and balance calculations are critical for flight safety, as they help determine the aircraft's load distribution. An improperly balanced aircraft can lead to difficult handling characteristics and increase the risk of accidents. By accurately calculating weight and balance, the dispatcher ensures the aircraft operates within its specified limits, thereby maintaining safety.

Optimizing routes involves analyzing weather conditions, air traffic, and available airways to formulate the most efficient flight path. This not only improves fuel efficiency and reduces costs but also ensures that the flight adheres to air traffic regulations and navigational constraints. Dispatchers use various tools and resources to make informed decisions that enhance operational efficiency while prioritizing safety.

The other responsibilities listed, while important in their own contexts, are not typically within the scope of an Aircraft Dispatcher's duties during flight planning.
