Wireless Power FOD

Can a stray coin stop your cell phone from charging? Texas Instruments explains how FOD lodged between the transmitter and receptor can prevent wireless devices from receiving an electrical power, in two videos: Wireless Power 101: FOD Introduction and Wireless Power 101: FOD Lab Session.

Is the F-18 Safer than the F-35?

The fighter wars are raging again, only this time in the press room instead of the skies. Boeing’s chief F/A-18 Super Hornet test pilot makes his case for the two-engine fighter being less vulnerable to catastrophic FOD incidents than the single-engine F-35 Lightning.

News Report: Airport Remains Open Despite FOD

January 24, 2016: The runway at Bauerfield International Airport (IATA: VLI, ICAO: NVVV) in the South Pacific island nation of Vanuatu has deteriorated to the point that some airlines have halted flights, according to a report by Newshub. Airport authorities have commenced short-term solutions, such as daily sweeping, to collect debris formed from loose pieces of tarmac. Read more…

White Paper: Comparing Airport Sweeper Technologies

January 4, 2016: There is no “one size fits all” single best technology for sweeping foreign object debris (FOD) from broad airport surface areas such as runways, taxiways, ramps and aprons, in all circumstances. So, instead of looking for the best sweeper available, focus instead on acquiring the most appropriate solution for your specific FOD control program. Read more…

News Report: Dead Deer vs. Aircraft

February 1, 2016: Hunters kill deer for food. Deer remains wash ashore near Sitka Rock Gutierrez Airport (SIT). Birds flock to the airport to dine on the remains. You can imagine how this can affect runway safety, so airport officials need to be extra vigilant during subsistence hunting season in Alaska, according to this article by KTOO Public Media. (Warning: graphic images) Read more…

News Report: Automated Detection System

December 8, 2015: Seattle-Tacoma International Airport (SEA) has installed a new FOD detection system for its recently-reconstructed center runway, according to a public statement by the Port of Seattle. Developed by the Israeli firm Xsight Systems, it utilizes image and radar processing algorithms to scan for debris and birds. Read more…

When does an airborne aircraft resemble FOD? When it’s smaller than practically everything else in the sky.

Drones — basically any unmanned, remotely-controlled aircraft — populate our nation’s airspace in greater and greater numbers. Depending upon design, they are also described by various acronyns, such as UAV (Unmanned Aerial Vehicles), UAS (Unmanned Aircraft Systems), sUAS (small Unmanned Aircraft Systems) or mUA (micro Unmanned Aircraft).

Military and law enforcement agencies already use them extensively. Long banned for commercial purposes, the FAA has recently proposed a set of regulations that would allow the routine use small drones. So, it is only a matter of time before all manner of little machines start buzzing over your community, ranging in size from a small plane to a large insect.

It is the miniature drones that concern manned aircraft pilots and industry officials, because in size and behavior they often resemble a bird in flight. They can collide with manned aircraft before pilots have the opportunity to take evasive action. Their relatively fragile construction can cause FOD issues on the ground during a forced landing or airborne break-up.

The FAA receives approximately two dozen reports per month of either near misses between UAV’s and manned aircraft, or of UAV’s flying close to airports. In 2013 a four-foot-long unmanned helicopter came within 200 feet of a Boeing 777 during a landing approach at JFK International Airport. An analysis of possible consequences, had a collision occurred, includes many of the same results of a bird strike, such as a fodded-out engine or cockpit intrusion.

Of course, in most cases, a bird strike will more likely to bring down the bird instead of the aircraft. With small UAV’s, it’s just the opposite, as this video of a hawk attacking and crashing a quad-copter will attest. Now you have the potential for FOD debris on the ground.

So many UAV’s have taken to the skies so quickly, including private craft making low-altitude flights (which are not usually regulated by the FAA), that government officials struggle just to keep up with the pace of events. For instance, a local videographer caused a stir when his camera-mounted drone buzzed a suburb of Chicago one night to make a promotional video. Confusion abounded over whether or not he had created a safety hazard, invaded people’s privacy and followed FAA regulations.

A drone strike would also create a more complex knot of insurance and court cases. Unlike a FOD incident caused by a generic piece of debris (such as a small bolt) of unknown origin, or a bird strike where the perpetrator is a natural object, after a drone strike it would not be difficult to trace the ownership and manufacturer of the offending craft. You would know exactly who to sue or prosecute.

One way to unclog the traffic, at least during takeoff and landing operations, is to give drones their own dedicated airport. The U.S. Army is doing just that, building a launch and recovery complex specifically for its military UAV’s. Located at Fort Bliss, Texas, it will include two runways, taxiways, a hangar, aprons and maintenance assets.

Military aviation faces some of its greatest FOD challenges when deploying to forward locations with no airfields or improved surfaces. To help solve this problem, a British manufacturer of portable runways developed an aluminum UAV Landing Mat for the Australian Armed Forces.

A partnership between the FAA, the UAV industry and model aircraft enthusiasts has put up a website, Know Before You Fly, that encourages responsible behavior by private drone operators.
