Airbus A350 software bug forces airlines to turn planes off and on every 149 hours • The Register
"Some models of Airbus A350 airliners still need to be hard rebooted after exactly 149 hours, despite warnings from the EU Aviation Safety Agency (EASA) first issued two years ago."

"Airbus' rival Boeing very publicly suffered from a similar time-related problem with its 787 Dreamliner: back in 2015 a memory overflow bug was discovered that caused the 787's generators to shut themselves down after 248 days of continual power-on operation. A software counter in the generators' firmware, it was found, would overflow after that precise length of time"

Russia denies role in Israeli airport GPS jamming - BBC News | RNTF
Blog Editor’s Note: Interesting follow-on report below from the BBC. Now we know it is spoofing vice jamming. Some of our thoughts:

The below article posits that this could be a spill over from Russian operations next door in Syria. Quite possible. It is the most likely explanation. At the same time, much of Russian operations in Syria involve “smart jamming,” or transmitting what seem to be valid GPS signals but with information that does not allow a receiver to calculate a position. According to the BBC, Israeli pilots have been reporting their receivers showing incorrect positions. This is not something you would see with smart jamming.
Russia is not the only actor in the region capable of spoofing. Virtually any nation or extra-governmental [OK, terrorist] organization would be capable of pulling this off.
It is also interesting to note that many of the approaches to the Tel Aviv airport are over the water. The interfering signal may be from a boat, a small buoy, or even a sub-surface device with only a small antenna showing above the water. Any of these would be very difficult to locate.

The radio navigation planes use to land safely is insecure and can be hacked | Ars Technica May 2019
Radios that sell for $600 can spoof signals planes use to find runways.

"Like many technologies built in earlier decades, the ILS was never designed to be secure from hacking. Radio signals, for instance, aren’t encrypted or authenticated. Instead, pilots simply assume that the tones their radio-based navigation systems receive on a runway’s publicly assigned frequency are legitimate signals broadcast by the airport operator. This lack of security hasn’t been much of a concern over the years, largely because the cost and difficulty of spoofing malicious radio signals made attacks infeasible.

Now, researchers have devised a low-cost hack that raises questions about the security of ILS, which is used at virtually every civilian airport throughout the industrialized world. Using a $600 software defined radio, the researchers can spoof airport signals in a way that causes a pilot’s navigation instruments to falsely indicate a plane is off course. "

"... all are careful to note that this kind of spoofing isn't likely to cause a plane to crash in most cases. ILS malfunctions are a known threat to aviation safety, and experienced pilots receive extensive training in how to react to them"

How a 50-year-old design came back to haunt Boeing with its troubled 737 Max jet - Los Angeles Times Mar 2019
"That low-to-the-ground design was a plus in 1968, but it has proved to be a constraint that engineers modernizing the 737 have had to work around ever since. The compromises required to push forward a more fuel-efficient version of the plane — with larger engines and altered aerodynamics — led to the complex flight control software system that is now under investigation in two fatal crashes over the last five months."

"The crisis comes after 50 years of remarkable success in making the 737 a profitable workhorse. Today, the aerospace giant has a massive backlog of more than 4,700 orders for the jetliner and its sales account for nearly a third of Boeing’s profit."

"The crisis comes after 50 years of remarkable success in making the 737 a profitable workhorse. Today, the aerospace giant has a massive backlog of more than 4,700 orders for the jetliner and its sales account for nearly a third of Boeing’s profit. But the decision to continue modernizing the jet, rather than starting at some point with a clean design, resulted in engineering challenges that created unforeseen risks."

"Over the years, the FAA has implemented new and tougher design requirements, but a derivative gets many of the designs grandfathered in, . . ."

"If the results of the investigation do not undermine the fundamental design of the aircraft, then the 737 Max’s future may not be in peril, aviation experts said. It may turn out all that’s needed is a software fix or additional pilot training."

Sorry LEOs, but FPAs Have No Incentive to Go Low-Cost - NSR Dec 2018
"According to NSR’s Commercial Satellite Ground Segment, 3rd Edition report, antennas will generate $44.9 billion cumulative revenues in the next 10 years. Requirements are wide and varied, from low-cost, fixed parabolic dishes for DTH (can be as cheap as $10 USD), to highly sophisticated antennas for mobility or Earth Stations that can cost several $100k USD. Consequently, antenna vendors adapt their products to the most lucrative markets. LEO constellations have a particular set of requirements that favor FPAs, especially in the low-end markets, but are FPA incentives aligned with LEO Constellations?"

"Today, SAC in Consumer Broadband is around $700-1,000 USD where the modem might be in the $300 range, antenna itself around $50, installation contributing $100 and the rest being marketing, credit validation and others. Consequently, an FPA priced in the $200-300 range could compete with traditional parabolics considering lower installation and marketing costs (product placement). Even considering these factors, prices for FPAs are still far from this benchmark, and only the architectures that have no other option (LEOs, Aero) will choose FPAs in the short to medium term."

"It will be impossible to see FPAs beating low-end parabolics in a direct cost comparison but, when including other elements of SAC, the equation is not so unfavorable. With continuous technology development, greater traction from LEOs and stagnation in verticals like Aero, we could see consumer-grade FPAs by the mid-2020s, at the earliest."

FAA Mulls Recommendations For Planned GPS Interference | Aviation Week Aug 2018
"The FAA says it is studying the recommendations a special committee issued earlier this year to better notify aircraft operators of planned GPS signal interference events caused by Defense Department testing."

"Loss of GPS in an aircraft equipped to report its position by automatic dependent surveillance-broadcast (ADS-B) “Out,” a capability the FAA requires by 2020, causes that aircraft to be lost as a target for onboard ADS-B “In” systems, affects aircraft depending on satellite-based augmentation systems for precision approaches and presents a problem for the FAA’s strategy to decommission some secondary surveillance radars (SSR) as ADS-B becomes its primary means of surveillance. The FAA is considering decommissioning 80% of terminal radars as ADS-B equipage by aircraft operators increases, the TOC says."

"In May 2017, the FAA asked the TOC, a committee managed by standards organization RTCA, to provide recommendations on improving practices related to “intentional” GPS interference caused by military testing events. The committee did not consider other sources of GPS interference such as solar weather, illegal jamming or signal spoofing."

Airlines to Take IFC Controls - Northern Sky Research Jul 2018
"NSR forecasts in its Aeronautical Satcom Markets, 6th Edition that the total satellite connectivity opportunity for IFC will reach $4.7 B in retail revenues annually by 2027 and most of it, roughly $3.8 B, will be generated from commercial passenger markets"

"To ‘share the load’ of IFC, airlines are taking more control over the interface where passengers (and sometimes 3rd party third-party payers in the hybrid model) are increasingly tapped to generate revenues. As service providers look to retreat from the expenses of paying for IFC in order to become more profitable, it is likely that the burden of costs will shift to airlines. "

"Following seven years of development, Phasor’s electronically steered antennas began testing in commercial use cases this year. These antennas are barely 2.5 centimeters thick, and are designed to be conformal in order to look at a wider angle 180 degrees, with dual-beam technology making them LEO and GEO interoperable."

"LeoSat, for example, sees itself as a disruptor in the defense market — which has traditionally relied upon GEO systems."

"By their own admission, Phasor will never be at the bottom of the food chain. And, while the super yachts of the world number in the thousands, fishing boats number in the millions"

"Isotropic Systems aims to be one of the leaders working to connect smaller maritime vessels and flight routes in India, Africa and Latin America. One way to achieve that, they believe, is by reducing the price point of terminal systems by 70 to 90 percent."

NextGen Reality Check: Problems Persist As FAA Installs Framework | Aviation Week, May 2018
"The infrastructure piece of the FAA’s NextGen air traffic control (ATC) modernization is “nearly complete,” Acting Assistant Administrator Pamela Whitley told an Air Traffic Control Association (ATCA) conference in Atlantic City, New Jersey. Other speakers described a U.S. national airspace system that has ongoing traffic-flow and congestion problems."

"Deployment of the nationwide ground infrastructure for automatic dependent surveillance-broadcast (ADS-B) is complete. DataComm, a capability that enables controllers and pilots to communicate by text messages, is operational at 57 airport towers; it now is being deployed to en route centers. SWIM (system-wide information management)—a data-sharing backbone the FAA uses to make flight, traffic flow, weather and other information available to subscribers—continues to add services, Whitley notes."

Will supersonic air travel's return be another white elephant? | New Scientist - issue 3159, Jan 2018
" SpaceX said its BFR rocket – ostensibly for Mars and moon missions – could provide anywhere-on-Earth, city-to-city transport in under an hour. And Virgin Galactic, focused on suborbital tourist trips with its rocket plane, also has city-to-city travel on its radar. So a supersonic future is a done deal? One barrier to a spaceplane route is that the US may deem landing a rocket abroad as breaching a ban on exporting this technology."

On Perception and Reality in Wireless Air Traffic Communication Security - IEEE Transactions on Intelligent Transportation Systems ( Volume: 18, Issue: 6, June 2017 )
Via Dale Hatfield

More than a dozen wireless technologies are used by air traffic communication systems during different flight phases. From a conceptual perspective, all of them are insecure, as security was never part of their design. Recent contributions from academic and hacking communities have exploited this inherent vulnerability to demonstrate attacks on some of these technologies. However, not all of these contributions have resonated widely within aviation circles. At the same time, the security community lacks certain aviation domain knowledge, preventing aviation authorities from giving credence to their findings. In this survey, we aim to reconcile the view of the security community and the perspective of aviation professionals concerning the safety of air traffic communication technologies. To achieve this, we first provide a systematization of the applications of wireless technologies upon which civil aviation relies. Based on these applications, we comprehensively analyze vulnerabilities and existing attacks. We further survey the existing research on countermeasures and categorize it into approaches that are applicable in the short term and research of secure new technologies deployable in the long term. Since not all of the required aviation knowledge is codified in academic publications, we additionally examine the existing aviation standards and survey 242 international aviation experts. Besides their domain knowledge, we also analyze the awareness of members of the aviation community concerning the security of wireless systems and collect their expert opinions on the potential impact of concrete attack scenarios using these technologies.

ADS-B Out ‘Non-Complying Emitters’ Occupy FAA | Commercial Aviation content from Aviation Week
"Two years out from its 2020 mandate to equip for automatic dependent surveillance-broadcast “Out” (ADS-B Out) position reporting, the FAA is grappling with a significant number of avionics that were installed improperly. And aircraft operators are lagging in equipping for the requirement, presaging a rush on repair stations as the mandate nears."

"By Jan. 1, 2020, aircraft flying above 18,000 ft. or internationally must be equipped with GPS and Mode S Extended Squitter (1,090 MHz) transponders and lower-flying airplanes in domestic airspace must have GPS and 978 MHz universal access transceivers to regularly broadcast their position—the function called ADS-B Out. Thus far, the FAA has not mandated ADS-B In, the ability to display air traffic on the flight deck, which requires costly software and display modifications."

"In response to a petition by trade group Airlines for America on behalf of its member carriers, the FAA in August 2015 issued Exemption 12555, which allows airlines to operate through 2024 using GPS receivers that do not meet required navigation accuracy and integrity performance standards. But they still must install Version 2 ADS-B Out transponders by the 2020 deadline. "

Aerospace Cybersecurity Challenges Need To Be Identified, Addressed | Connected Aerospace content from Aviation Week
via Dale Hatfield

"The situation illustrates the level of reliance that integral parts of the aviation ecosystem are placing on network connectivity, and the importance of ensuring those networks are both reliable and secure as the industry’s digitalization gains momentum."

"Aviation’s emphasis on systems safety through risk identification and mitigation is well-established."

Pete Cooper, Atlantic Council senior fellow: “Previously, aviation systems were relatively secure due to the bespoke nature of their design, isolation from other systems, and little in the way of communication protocols.”

"Among the [Atlantic Council] study’s key takeaways: Aviation’s march toward an increasingly digital future is opening it up to significant cybersecurity threats, and the industry must move purposefully and quickly to ensure that systemic challenges do not increase an already formidable risk."

"But the consensus among cybersecurity experts and aviation IT specialists is that, while secure systems are the goal, breaches are inevitable. That places the onus on recovery."

November/December 2017 - Inmarsat CEO and the $1 Billion Target | Via Satellite Nov 2017
"Can Inmarsat create a $1 billion dollar revenue stream in aviation? Inmarsat CEO Rupert Pearce is confident the company can do this in around 10 years’ time. It is an ambitious projection, but recent deals with the likes of Qatar Airways and Avianca underline there is still huge potential in this business for Inmarsat and others."

"But aviation is more than just In-Flight Connectivity (IFC) for Inmarsat. The company has three other aviation businesses — government, business and general aviation — and its safety business. What matters to Inmarsat in the medium term is free cash flow generation, meaning that gross margin, net profit margin and capital expenditure levels are vital to the trajectory of its business."

IOT: “The utility for satellite is that you can put connectivity through a very small device on your car or on your train and the applications are many and various. For trains, you are looking at next generation signaling, safety management and operation of the cargo. For cars, you are looking at Over-the-Air (OTA) updates to patch software and protect the vehicle,” he says. “You are also looking at a new era of telematics and treating cars as a large community that you can track and draw situational awareness from.”

How can airlines stop hackers pwning planes over the air? And don't say 'regular patches' • The Register
Via Dale Hatfield

See discussion thread:

"A plane was compromised as it sat on the tarmac at a New Jersey airport by a team of boffins from the worlds of government, industry and academia, we're told. During the hack – the details of which are classified – experts accessed systems on the Boeing 757 via radio-frequency communications."

"A couple of years ago, security researcher Chris Roberts was accused of hacking into the controls of a United Airlines plane in midair via the inflight entertainment system. Roberts tweeted about airplane network security during the flight to Syracuse, New York. He was questioned on arrival by the Feds. However, there is no evidence he accessed flight control systems, and no charges were ever brought.

In 2014, Brad Haines poked air traffic control and ADS-B security, and found various threats to installations."

"Recently designed commercial aircraft – such as Boeing’s 787 and the Airbus Group A350 – were drafted with computer security in mind, we're told, but resisting or preventing cyber-attacks were not on the design criteria list for older aircraft, which still make up the vast majority of airline fleets."

High-Altitude Platforms — Present Situation and Technology Trends, J. Aerosp. Technol. Manag. vol.8 no.3 , Jul/Sep 2016

High-altitude platforms (HAPs) are aircraft, usually unmanned airships or airplanes positioned above 20 km, in the stratosphere, in order to compose a telecommunications network or perform remote sensing. In the 1990 and 2000 decades, several projects were launched, but very few had continued. In 2014, 2 major Internet companies (Google and Facebook) announced investments in new HAP projects to provide Internet access in regions without communication infrastructure (terrestrial or satellite), bringing back attention to the development of HAP. This article aims to survey the history of HAPs, the current state-of-the-art (April 2016), technology trends and challenges. The main focus of this review will be on technologies directly related to the aerial platform, inserted in the aeronautical engineering field of knowledge, not detailing aspects of the telecommunications area.

ANALYSIS: Administration's sloppy ATC rhetoric hurts chance for reform | Opinions content from ATWOnline, Sep 2017
"The ATC entity would be independent, like the US Postal Service (certainly no one’s idea of a private corporation), and be removed from the federal government’s annual appropriations process. That way, it could make large investments in modernization that may not necessarily pay off immediately, but would generate huge benefits down the line. And it could make course corrections along the way as technology evolved and changed without cumbersome legislative alternations. It is not turning ATC over to a private, for-profit corporation. And FAA would become the regulator of the ATC entity and no longer be in the odd position of regulating itself managing ATC. This is basically how ATC works in most of the industrialized world."

"There are two main groups opposed to spinning off ATC from FAA: 1) good-government liberals who are against “privatizing” what they see as key government functions and 2) the general aviation community, given voice by the National Business Aviation Association (NBAA)."

"Current situation is that wind tunnel has been replaced by numerical simulation in the area where turbulence modelling is not highly demanded by accuracy demands or physics complexity.

However, for being able to model some part of the physics the industry can only go hardware testing (wind tunnel)."

In 1973 the Federal Aviation Administration (FAA), worried about loud sonic booms, banned civil aircraft from flying at supersonic speeds above America. But planes are now lighter, more aerodynamic, and contain more efficient engines, explains Eli Dourado of Mercatus. That makes them quieter. With start-ups trying to build commercially viable supersonic jets, Mr Dourado thinks the FAA should replace the ban with a maximum permissible noise level. "

[1610.06754] A Localization Approach for Crowdsourced Air Traffic Communication Networks
In this work, we argue that current state-of-the-art methods of aircraft localization such as multilateration are insufficient, in particular for modern crowdsourced air traffic networks with random, unplanned deployment geometry. We propose an alternative, a grid-based localization approach using the k-Nearest Neighbor algorithm, to deal with the identified shortcomings. Our proposal does not require any changes to the existing air traffic protocols and transmitters, and is easily implemented using only low-cost, commercial-off-the-shelf hardware.

FAA issues GPS interference flight advisory : GPS World June 2016
[[Editor’s note: After this story was posted, and after the Navigate! enewsletter containing it was sent out to 27,128 subscribers, GPS World received notice that in fact the U.S. Navy canceled plans to jam GPS signals in the vicinity of the China Lake, California, Naval Air Weapons Station. The Aircraft Owners and Pilots Association (AOPA) had raised concerns about the impact on civilian air traffic and the size of the affected area. The Navy did not reveal the cause of the cancellation, other than to say the reason was “internal.”]]

GPS Interference Notam For Southwest - AVweb flash Article - June 2016
"A Notam (PDF) is warning operators of “all aircraft relying on GPS” of widespread GPS outages starting Tuesday throughout the Southwest and especially southern California. Although the FAA doesn’t go into detail, it seems the military is testing something that can disrupt GPS over a huge area, centered on China Lake, California, home of the Navy’s China Lake Naval Weapons Center. "
"Operators of Embraer Phenom 300 business jets are being urged to avoid the area entirely. “Due to GPS Interference impacts potentially affecting Embraer 300 aircraft flight stability controls, FAA recommends EMB Phenom pilots avoid the … testing area and closely monitor flight control systems,” the Notam reads."

Anti-drone system for airports passes tests : GPS World Feb 2016
"Each month, the Federal Aviation Administration (FAA) receives more than 100 reports from pilots and others who spot what appears to be an unmanned aircraft (UAS) flying close to an airport or a manned airplane. It’s become a serious safety concern for the agency, and a potential security issue for the Department of Homeland Security (DHS). In addition to the FAA’s ongoing outreach and education efforts, an additional step toward a solution is to detect and identify these “rogue drones” and their operators. Recently, the FAA partnered with DHS and CACI International to explore how the company’s prototype detection technology may help detect UAS in the vicinity of airports."

WRC-15 set to approve wireless avionics in 4.2-4.4 GHz band - PolicyTracker Sep 2015
"The band currently has a primary allocation to the Radio Navigation service, and is used for radio altimeters." "Wireless avionics intra-communication (WAIC) systems are intended to provide more wireless communications in aircraft to supplement or replace systems that are currently dependent on wires. One advantage of these is the creation of additional safety lines of communications in case the wired systems fail, known as dissimilar redundancy. Perhaps the biggest advantage of these systems is that they can substantially reduce the weight of aircraft. PolicyTracker understands that around a third of wires can be replaced through wireless avionics. The impact of this on airlines’ fuel bills could be significant. For example, in the Airbus A380 super-sized jet, the wires weigh 5700 kg and stretch for 470 km. "

In-flight Wi-Fi could potentially open up avionics controls to hackers - RCR Wireless April 2015
“The U.S. Government Accountability Office on April 14 released a report detailing the potential for in-flight Wi-Fi networks to be compromised by cyber attacks.” “Wired reports that particular safety concerns are associated with Boeing’s 787 Dreamliner and the Airbus A350 and A380 models. From that report, those models “have Wi-Fi passenger networks that use the same network as the avionics systems of the planes, raising the possibility that a hacker could hijack the navigation system or commandeer the plane through the in-plane network.” While the passenger portion of the network is separated from the avionics side, that configuration isn’t foolproof.”

Germany blocks use of MSS S-band for in-flight connectivity
Germany seems to be blocking Inmarsat's plans because DT has invested heavily in an alternative "Aero CGC services are a new initiative by Inmarsat to provide in-flight Wi-Fi using a hybrid of satellite and earth stations. Inmarsat wants to be able to roll out these services using the 2 x 15 MHz assignment of pan-European spectrum (1980-2010 MHz and 2170-2200 MHz) it gained following the 2008 EC Decision. " "Direct Air to Ground Communication (DA2GC). PolicyTracker understands that DA2GC is a big programme for Deutsche Telekom. . . .

AT&T: We're using WCS C, D Block spectrum for in-flight Wi-Fi because of interference concerns - FierceWireless Aug 2014
"In a new filing with the FCC, AT&T Mobility (NYSE: T) said that it doesn't believe it can use its WCS C and D Block spectrum for a mobile LTE network because the system would create too much interference with other operations in nearby spectrum bands. As a result, the carrier said it hopes to use the spectrum to provide in-flight Wi-Fi services because pointing the antennas up at the sky would reduce the possibility that the network would interfere with operations in adjacent bands, including Sirius XM radio." "AT&T said it has moved forward with plans to use the WCS A and B Blocks for its mobile LTE network." "The carrier said ground-to-air transmissions should occur over the D Block while air-to-ground services should occur over the C Block."

Expert Advice: The Low Cost of Protecting America : GPS World
"The U.S. National Space-Based Positioning, Navigation, and Timing (PNT) Advisory Board published a seminal white paper in 2010 on the topic, strongly recommending the establishment of an eLoran system." "A well-configured eLoran system can provide navigation accuracy to within 8 to 10 meters and timing accuracy to within 30 nanoseconds. This meets the needs of an estimated 95 percent of users in the United States." "There are also signs that the U.S. intelligence, cyber, and defense communities are becoming more and more concerned. North Korea’s repeated jamming of satellite navigation and timing signals has delivered a particularly powerful lesson. South Korea has reacted by committing to establishment of a robust eLoran system. The UK has established an eLoran system and is expanding it. Russia and China have retained their versions "
