Flight planning traditionally relies on classic algorithms that struggle to incorporate flexible human preferences.  \nWe present FRAMe, an End-to-End Large Language Model (LLM) Flight Planning tool with RAG-based Memory and Multi-modal Coach Agent. Our system integrates a planner LLM with a multi-modal coach agent and retrieval augmented generation (RAG)-based memory to generate flight plans that satisfy mission constraints while aligning with human flight operator preferences. We demonstrate the system ina range of real-world-inspired scenarios of varying difficulty levels. Across four LLMs, the full FRAMe system (RAG and coach) yields the highest validity for every planner (up to 93.8% aggregate, 99% on Easy scenarios for the strongest planner) and shifts preference-relevant metrics in the operator-favored direction where the metric has headroom. FRAMe signifies how advanced LLMs can be deployed for human-centric mission planning, translating natural language instructions into safe, efficient, and flexible flight routes.

Maintaining safe and efficient flight planning within such dense and complex airspace presents a major challenge. Flight restrictions, coupled with the often subjective and context-dependent nature of mission-specific requirements, make it difficult to define rigid, mathematical objectives that fully capture operational intent.  \nClassical path planning algorithms, such as A∗ and rapidlyexploring random trees (RRT, RRT∗ ) (Kuffner & LaValle, 2000 ; LaValle, 2006), can compute optimal, obstacle-free trajectories; however, they depend on explicitly defined mathematical objectives and constraints, which limits their ability to capture nuanced human pilot preferences, such as trading off flight duration against waypoint complexity. Asthe scale and complexity of eVTOL operations continue to grow, there is an increasing need for automated planning systems capable of interpreting such nuanced mission intent.  \nOne promising technology to bridge this gap is to use LLMs for planning. For instance, in robotics and navigation, the SayCan framework (ichter et al., 2023) demonstrated the capability of LLMs to guide robots using natural language to do feasible and contextually appropriate actions. In planning, hybrid approaches have leveraged LLMs to generate subgoals for classical planners (Meng et al., 2024 ; Liu et al., 2023 ; Dagan et al., 2024), while other methods integrate solver heuristics to better guide LLM generated plans (Wu & Mitra, 2024 ; Hirsch et al., 2024) . Researchers have also explored combining LLMs with reinforcement learning (RL) to enhance reasoning capabilities. For instance, S2RCQL (Deng et al., 2025) augments prompts using information derived through Q-learning, and another approach employs LLMs to generate semantic hints for contextual RL in motion
