什么是 FOD，为什么它对机场是致命的

What is FOD and why it is critical to airports

FOD（Foreign Object Debris，外来物）指跑道、滑行道、机坪上一切不属于航空器的物体——螺栓、垫圈、维修工具、砂石、塑料碎片、甚至鸟类残骸。高速吸入发动机可导致叶片打伤、空中停车；卷入起落架或轮胎可引发爆胎与偏出跑道。行业普遍引用的经验数据是：FOD 每年给全球航空业造成数十亿美元的直接维修、延误与航班取消损失。因此 FOD 管理被 FAA 与 ICAO 列为机场安全运行的核心闭环之一。

FOD (Foreign Object Debris) means any object on runways, taxiways and aprons that does not belong to an aircraft—bolts, washers, maintenance tools, sand, plastic fragments, even bird remains. Ingested at high speed it can damage engine blades and cause in-flight shutdowns; caught in landing gear or tires it can trigger blowouts and runway excursions. Widely cited industry figures put the annual direct cost of FOD to global aviation at billions of dollars in repair, delay and cancellation. That is why FOD management is treated by FAA and ICAO as a core safety loop.

FAA 与 ICAO 对清扫的硬性要求

Hard requirements from FAA and ICAO

美国联邦航空管理局的咨询通告 AC 150/5210-24A《Airport Foreign Object Debris (FOD) Management》给出了 FOD 管理的完整框架，明确将“定期清扫（sweeping）”与“磁吸除铁（magnetic pickup）”列为标准控制措施，并对清扫设备提出性能规格，例如清扫宽度、垃圾箱容量、边刷对墙角/道肩的覆盖能力。国际民航组织的 Annex 14《机场设计与运行》则要求对跑道、滑行道实施规定的巡视与清扫频次，确保道面无可能损伤航空器的异物。两者的共同点是：不能只靠人工目检，必须有机械化、可记录的清扫能力。

The FAA advisory circular AC 150/5210-24A 'Airport Foreign Object Debris (FOD) Management' provides a full framework, listing periodic sweeping and magnetic pickup as standard controls and specifying equipment performance—sweep width, hopper capacity, and edge-brush coverage of shoulders and corners. ICAO Annex 14 (Aerodrome Design and Operations) requires defined inspection and sweeping frequencies for runways and taxiways so the surface is free of debris that could damage aircraft. Both agree on one point: visual check alone is not enough—mechanized, recordable sweeping is required.

跑道与机坪的清扫频率、作业窗口

Sweeping frequency and operational windows

机场道面清扫高度依赖“天窗窗口”——通常在航班间隙、夜间停航或低流量时段进行，避免干扰运行。大型枢纽普遍在每日首班前、末班后各安排一次全面清扫，并在施工、除冰、除雪或大风扬尘后即时补扫。FOD 巡检（FOD walk）仍由人员按计划进行，但机械化扫地车承担了大面积的连续清除任务，显著降低人工巡检的盲区与体力消耗。

Airfield sweeping depends heavily on the 'window' between flights—usually at night, before the first departure or after the last arrival, to avoid disrupting operations. Major hubs typically schedule a full sweep before first flights and after last flights, plus immediate re-sweeping after construction, de-icing, snow removal or windy dust events. FOD walks by personnel still run on plan, but mechanized sweepers carry the bulk of continuous clearance and sharply cut blind spots and fatigue of manual patrols.

磁吸除铁与封闭式控尘

Magnetic pickup and enclosed dust control

金属类 FOD（螺栓、垫片、钢丝）占跑道异物的很大比例，磁吸装置可在清扫主刷之外额外回收铁磁性碎片，是 FAA 框架推荐的补充手段。与此同时，干式清扫若不加控尘，二次扬尘反而会把细小颗粒重新分布到道面与设备区。机场场景优先选用全封闭、带洒水降尘与高效过滤的扫地车，避免清扫过程本身成为新的污染来源。

Metallic FOD (bolts, washers, wire) makes up a large share of runway debris; magnetic bars recover ferrous fragments beyond the main brush and are a recommended supplement under the FAA framework. At the same time, dry sweeping without dust control re-scatters fine particles across the surface and equipment areas. Airside operators favor fully enclosed sweepers with water spray and high-efficiency filtration so the sweeping process itself does not become a new source of contamination.

扫地车 vs 人工巡检：机场如何组合

Sweeper vs manual patrol: how airports combine them

人工 FOD 巡检擅长发现零散小件与目视异常，但覆盖慢、易疲劳、夜间效率低；机械化扫地车清洁宽度大（大型驾驶式可达 2 米以上）、垃圾箱容量高、可连续作业，是跑道与机坪的主体清除力量。成熟做法是“磁吸+机扫+人工补检”三位一体：扫地车主扫大面，磁吸回收金属件，人员按计划巡检盲区与边角。相比纯人工，机扫可替代约 20–30 名清洁工的连续作业量（经验值），且作业记录可追溯。

Manual FOD patrols are good at spotting scattered small items and visual anomalies but are slow, tiring and weak at night. Mechanized sweepers offer wide cleaning paths (large ride-on units exceed 2 m), high hopper capacity and continuous operation—the main clearing force for runways and aprons. The mature setup is 'magnetic + machine + manual': the sweeper clears the broad area, magnets recover metal, and personnel inspect blind corners on schedule. Versus pure manual work, machine sweeping can replace the continuous output of roughly 20–30 cleaners (experience-based) with traceable records.

ApexClean offers a sweeper matrix for airside surfaces: the large ride-on sweeper YLBA320 and large ride-on road sweeper YLBA091 suit continuous wide-area cleaning of runways, taxiways and aprons; the fully enclosed sweeper YLBA5300 controls dust via sealed cabin and filtration for dust-sensitive zones; the all-weather sweeper YLBA085 handles night-shift low temperatures and outdoor duty. These are mature configurations, combinable by sweep width, hopper capacity and magnetic attachment needs.

维护与合规要点

Maintenance and compliance notes

机场扫地车维护重点在边刷/主刷磨损、垃圾箱密封、过滤系统与磁吸条清洁。建议建立每班的清扫里程与垃圾重量记录，作为 FAA/ICAO 合规与保险可追溯的依据。采购时向厂家确认清扫宽度、水箱与过滤等级、磁吸附件与防爆（加油/除冰区）配置，确保设备能力与机场运行标准匹配。

Key maintenance for airside sweepers is edge/main brush wear, hopper sealing, filtration and magnetic-bar cleaning. We recommend a per-shift log of sweeping distance and debris weight as traceable evidence for FAA/ICAO compliance and insurance. When procuring, confirm with the manufacturer the sweep width, water-tank and filtration grade, magnetic attachment and (for fueling/de-icing zones) explosion-proof configuration so capability matches airfield standards.
