目前，设计用于执行以有效载荷为中心的机动的飞行系统需要预先构建的程序和特殊的手动调整制导模式。为了通过有效载荷引导飞行的目标和自动驾驶功能之间的强耦合来实现智能机动，需要重新思考传统的自动驾驶设计和功能。有效载荷制导飞行研究研究以传感器和有效载荷为中心的自动驾驶模式、体系结构和算法，这些模式、体系结构和算法为飞行器提供多层智能制导、导航和控制，以实现与有效载荷传感器相关的任务目标，并考虑各种约束，如飞机的性能限制、目标跟踪和估计、障碍物回避和约束满足。有效载荷定向飞行需要一种精确的轨迹规划方法，使系统能够预期来自机载传感器套件的预期回报。本文对文献中使用的现有技术进行了扩展，以快速准确地规划飞行轨迹，以预测和优化机载有效载荷传感器的预期回报。
Presently, flight systems designed to perform payload-centric maneuvers require preconstructed procedures and special hand-tuned guidance modes. To enable intelligent maneuvering via strong coupling between the goals of payload-directed flight and the autopilot functions, there exists a need to rethink traditional autopilot design and function. Research into payload directed flight examines sensor and payload-centric autopilot modes, architectures, and algorithms that provide layers of intelligent guidance, navigation and control for flight vehicles to achieve mission goals related to the payload sensors, taking into account various constraints such as the performance limitations of the aircraft, target tracking and estimation, obstacle avoidance, and constraint satisfaction. Payload directed flight requires a methodology for accurate trajectory planning that lets the system anticipate expected return from a suite of onboard sensors. This paper presents an extension to the existing techniques used in the literature to quickly and accurately plan flight trajectories that predict and optimize the expected return of onboard payload sensors.
