With the proper military equipment , a single somebody can target a plane from three miles out using a heat - seeking projectile . While such a nightmare is a rare occurrence , FedEx has hold to the FAAseeking commendation to install alaser - based , anti - missile vindication systemon its cargo plane as an add guard measure .
The basics of how heat - seek missiles oeuvre is mostly self - explanatory . They point and track a source of heat — such as the hot melodic phrase come out of a jet ’s locomotive engine — and mechanically make in - flying course adjustments so the projectile attain its target without any input from the weapon ’s manipulator . They ’ve been popularized in action flick , but the engineering is far from infallible .
Military planer channel solar flare that can be remotely ignite and boot out by a archetype to throw off a heat - seeking projectile ’s targeting system with an alternate estrus root , while the plane itself performs evasive manoeuvre in an effort to gull the incoming missile . Those countermeasures are less effective for larger aircraft , however , with large passion signatures as a result of multiple jet engines under each backstage , and well less manoeuvrability than a scrapper jet . An substitute resolution is the employment of a gadget that fires an infrared laser directly at an incoming missile in an attempt to disrupt its ability to track the aircraft ’s heat signature . It ’s not alone unlike someone struggling to get a baseball game with the sun in their eyes , but with the sun actively track and targeting the person wearing the mitt .

FedEx ’s petition to the Federal Aviation Administration , filed on Jan. 4 , did n’t come all out of left field , however . In 2008 , the troupe worked with Northrop Grumman to test its anti - missile laser - based defense systems on 12 of the transportation society ’s cargo planes for over a year . At the prison term , Northrop Grumman herald that its “ system is quick to be deployed on civilian aircraft , ” although no commercial parliamentary procedure had been locate at the time , according to a company spokesperson . That may have change , however .
FedEx’sapplication to the FAAto appropriate it to install and use anti - missile systems on its Airbus Model A321 - 200 cargo planes does n’t specifically mention Northrop Grumman ’s hardware , so the shipping companionship could now be working with another troupe , but the purpose hardware is basically the same as what was tested back in 2008 .
In theapplication papers , which is “ schedule to be published in the Federal Register on Jan. 18 , ” FedEx mention “ several incident afield ” where “ civilian aircraft were fired upon by man - portable air defense systems ” which are nearly impossible to find yield their range of process , but undoubtedly a serious terror when operating aircraft in some parts of the world .
The big job with FedEx ’s covering seems to be that the FAA ’s “ conception standard for transport category airplanes did not envisage that a design feature film could protrude infrared laser energy outside the airplane ” and that the “ FAA ’s pattern monetary standard are poor to direct this capability . ” As a result , the demurrer system is being considered a “ novel or unusual design feature of speech ” and as such will be subjected to several special safety regulations given how dangerous intense infrared light can be to the skin and eyes of “ persons on the aircraft , on the ground , and on other aircraft . ”
These regulation will include the ability to completely deactivate the system while the plane is on the dry land to forbid “ inadvertent mathematical operation , ” a intent that prevents inflight usage from ever damaging the aircraft itself or lay on the line the safety of the crew and passengers , even in the case of a system of rules failure or accidental operation . They also require extensive markings , labels , warnings , and support for everyone from criminal maintenance stave to earth crew , to pilots , admonish them of the optical maser ’s class and risks , include an addendum to the trajectory manual explaining the accomplished habit of the system .
