无人机已经到达目标上空，为什么仍然不能投放物资？

无人机投影已进入投放区，高度和授权时间窗也满足要求，但落点附近仍有地面人员，当前净空只有10米。

target overhead reached ≠ drop zone clear ≠ payload release authorized

到达条件都成立，释放条件仍不成立

投影进入投放区

true

高度与时间合规

true

地面投放区净空

false

true AND true AND false AND true → immediate_release_authorized = false

悬停等待，不等于任务失败

立即投放

禁止

人员仍在30米安全半径内，释放命令必须被阻断。

payload_release_command = blocked

悬停并清场

可恢复

通知地面人员撤离，取得15秒内的新净空证据后重新验证。

resume_when = clear AND fresh

到达目标只是导航阶段完成。载荷释放是新的高风险动作，需要独立的实时证据和动作门控。

第一步：让模型选择行动

得到模型建议后返回本页，选择对应动作并验证。

第二步：验证模型动作

验证结果等待选择

模型候选动作—

本地任务动作hold_position_and_request_ground_clearance

当前人员净空10 m

最低投放净空30 m

候选来源：model_generated；投影、高度、时间和距离：local_deterministic；地面占用证据：application_verified。

GT19演示单一人员和静态落点。真实投送还需核验风场、载荷漂移、地形坡度、通信链路、人员移动趋势、悬停余量和备降策略。

GT20 已上线：车辆获得绿灯后，仍需独立核验下游出口净空和整车可驶离空间，不能把信号许可直接等同于路口入口授权。
