Which of the following is a function of the landing plan?

The correct answer is managing the descent of aircraft. The landing plan is a critical component of flight operations, particularly in military air assault scenarios where precision and safety are paramount. This function involves outlining the specific procedures and configurations for how aircraft will descend and land during an operation.

By detailing the descent phase, the landing plan ensures that aircraft come in safely and effectively to the designated landing zones, considering factors such as wind conditions, terrain, and potential obstacles. This meticulous management of an aircraft's descent is crucial to ensuring the safety of both personnel and equipment during the landing phase of an operation.

The other choices, while relevant to overall operations, do not specifically align with the primary functions of the landing plan as it pertains to aircraft descent. Factors like air traffic management and communication with ground teams are essential support elements but are not the direct responsibility of the landing plan itself. Additionally, strategizing cargo placement relates to load planning rather than the landing operation.
