Insights from recent industry conversations on airfield productivity, sweeping efficiency and the operational cost of time on the ground.
The conversation airports keep having
At a recent industry gathering of the American Association of Airport Executives (AAAE), one theme surfaced again and again in conversations with airport operators: time. Specifically, the hours quietly consumed by Foreign Object Debris (FOD) sweeping and the operational compromises that come with it. The pain point is rarely the act of sweeping itself. It is the trade-off: runway occupancy that delays movements, ramp closures that disrupt turnarounds, and maintenance windows that stretch longer than they should. For airports under pressure to grow throughput without growing capital budgets, the question is no longer whether to sweep, but how to sweep faster, more reliably, and without compromising coverage. This is the question we want to address in this month’s edition: how can airfield operators boost FOD sweeping productivity without significant new investment?
Why the existing model is straining
The traditional approach, sweeper trucks paired with rotating-broom systems supplemented by FOD walks, has served the industry well, but it is showing its age. Three structural issues stand out.
Speed limits the technology, not the airfield. Most mechanical sweepers operate well below posted airside speed limits. On a long runway, the difference between sweeping at 10 mph and sweeping at 40 mph is measured in tens of minutes of occupancy per pass, and tens of minutes that the runway is unavailable for revenue movements.
First-pass efficiency is inconsistent. Rotating brooms tend to redistribute fine particulates as much as they collect them. That means repeat passes, longer cycles, and an open question every time a runway reopens: did we actually get it all?
FOD walks have their place, but they are not a substitute. Their genuine value lies in reinforcing a culture of vigilance, particularly in military and high-discipline operating environments where the walk itself is part of the safety ritual. As an inspection method, however, visual human sweeping is inherently unreliable. It is limited to coarse, visible debris and to whatever the team’s focus, fatigue and field of view allow on the day. The fine, granular FOD that quietly damages engines and tires is rarely what a walk picks up. The cumulative effect is straightforward: operators are spending more time sweeping than they should, with less confidence in the outcome than they want.
The financial weight of the problem
FOD is not a small line item. The U.S. Federal Aviation Administration cites estimates that place the global annual cost of FOD at up to USD $22.7 billion, accounting for both direct damage and indirect operational impacts.
The FAA’s own guidance is unambiguous on prevention as well: under Advisory Circular 150/5210-24A, airports are expected to maintain active FOD management programs that include systematic removal, not just inspection. The International Civil Aviation Organization defines FOD plainly as “an inanimate object within the movement area which has no operational or aeronautical function and which has the potential to be a hazard to aircraft operations”. It is a definition that captures both the bolt on the runway and the sand on the ramp.
In short: the regulatory framework expects sweeping. The economics demand efficiency. The remaining variable is how operators choose to do it.
Where the time actually goes
Looking at a representative major commercial airport, FOD does not distribute evenly across the airfield. Roughly 55% of FOD accumulates in apron and ramp areas, 35% on taxiways, and 15% on runways. Yet runway sweeping consumes a disproportionate share of operational attention because every minute the runway is closed has a movement cost attached to it.
This asymmetry, where the ramp is the highest-risk zone but the runway is the highest-cost zone to sweep, is precisely where productivity gains live. Solve the runway speed problem and the ramp coverage problem at the same time, and total sweeping time drops without any change in coverage standards.
The case for a tiered sweeping deployment
The FOD*BOSS sweeper-mat is a towed system, deployed behind any suitable airside vehicle: a tug, a truck, a utility vehicle, even an EV. It is multi-patented, requires no special licensing, and operates at speeds of up to 40 mph (65 kph), with documented pick-up rates exceeding 99% and 100% retention of debris within the sweeper. Crucially, it scales, and that is where the productivity argument becomes interesting.
Rather than treating the airfield as one undifferentiated surface, operators can match the FOD*BOSS configuration to the Airside Operating Area (AOA) they are sweeping:
• Triplex on the runway. A three-mat configuration sweeps the full runway width in a single pass, turning what is typically an hours-long task into one measured in minutes. The runway reopens faster, and movements resume sooner.
• Duplex on the taxiway. A two-mat configuration handles taxiway widths efficiently while leaving the runway capacity untouched.
• Single on the ramp. Concurrent sweeping in the apron, the most FOD-prone zone, runs in parallel without competing for the same equipment.
For airfields where the ramp is the dominant risk surface, an alternative deployment uses three single units across multiple ramp areas simultaneously, dramatically reducing total sweep time in the zone where 55% of FOD originates. The investment profile is what makes this work: a tiered FOD*BOSS deployment costs a fraction of a single capital sweeper truck program and avoids the multi-year depreciation, fuel burn, licensing, and maintenance overhead that comes with diesel-engine equipment.
Getting more done with the same resources
The phrase that came up repeatedly in those AAAE conversations was getting more done with the same resources. It is a useful frame, because it shifts the discussion away from headcount or capital budgets and toward outcomes: first-pass effectiveness, AOA occupancy time, and confidence in the result.
When sweeping speed is no longer the limiting factor, when first-pass coverage is reliable, and when ramps, taxiways and runways can be addressed concurrently rather than sequentially, the productivity gains compound. The same crew, the same shift, the same budget, and meaningfully more airfield covered to a higher standard.
