This article presents the development of a fixed-wing UAV flight controller using a complete parallelism embedded system as a FPGA. Many solutions for UAVs flight controllers are based on embedded sequential systems. However, these systems are not perfect. The greater number of processes and tasks being executed simultaneously, the more variables such as precision, speed of response and synchronism may suffer. Our proposed flight controller solves this problem because it is based on a concurrent system and can therefore, execute many processes at the same time. The development of this flight controller represents just one part of the “Drone Bosco” project, where university students from Universidad Don Bosco are constructing the first UAV designed completely in El Salvador. The solution was designed and implemented taking into consideration specific characteristics of other areas of the project such as Radio Control Systems, Power Generation Systems and Aerodynamics. These considerations are outlined in this article. The flight controller is based on a state machine system that migrates from state to state depending on the stimulus received from sensors like accelerometers, tachometers, compass, pitot, GPS, etc. Another feature developed in this project is an emergency system that provides enough intelligence and robustness to secure the integrity of the aircraft in case a problem occurs during missions. Features like high speed of response, adaptable calibration and parallelism are achieved with our solution. Moreover, given that many parameters are generic, it has the flexibility to migrate to other fixed-wing UAVs with different characteristics. A similar approach could be applied in the future for the development of other devices that need navigation controllers with these characteristics, for example rockets or rovers. The results obtained in the simulations and tests of the flight controller system are described in detail in this article.

The ACAS Xu program has developed both a horizontal and vertical collision avoidance logic to enable unmanned aircraft to avoid manned aircraft. Each logic supports a variety of surveillance sources and is individually capable of providing a significant safety benefit. This paper proposes a logic selection function that can effectively arbitrate between the horizontal and vertical logics to achieve an overall safety benefit without requiring the use of simultaneous horizontal and vertical maneuvers. Monte Carlo simulations show that the logic selection function can provide a performance benefit for a variety of surveillance sources.

NASA is developing the Flight Awareness Collaboration Tool (FACT) to support airline and airport operations during winter storms. The goal is to reduce flight delays and cancellations due to winter weather. FACT concentrates relevant information from the Internet and Federal Aviation Administration on one screen for easy access. It provides collaboration tools for those managing the winter weather event including the airline operations center, airport authority, the air traffic control tower, and de-icing operators. We have formed a user team from an affected airport to guide the design and evaluate the Web-based prototype. Future work includes adding predictive capabilities, conducting a simulation to test FACT in a realistic environment, and evaluating the tool in an operational environment.

DO-331 is the supplement of DO-178C for model-based development. DO-331 is an objective-based guidance, which defines a set of objectives that have to be achieved for the model-based development of aeronautical software. The guidance also recommends the evidence in terms of activities and work products that should respectively be carried out and produced to meet the objectives. To explain why the evidence collected supports the claims concerning objectives achievement, manufacturers could adopt a safety case-based approach. Fail-SafeMBT is an academic, recently proposed, and potentially innovative model-based testing process, which needs compelling arguments to be adopted for the development of aeronautical software. To reduce the gap between industrial settings and academic settings, in this paper, we adopt the safety case-based approach and we explain how to semi-automatically derive means for compliance, aimed at arguing Fail-SafeMBT's compliance. Our focus is limited to the Verification Planning Process and we contribute to partially justify the adequacy of Fail-SafeMBT to act as process evidence by creating fragments of compelling arguments. To do that, we first manually check if Fail-SafeMBT includes DO-178C/DO-331-compliant process elements, then we model Fail-SafeMBT in compliance with Software Process Engineering Meta-model 2.0, then, we derive process-based arguments from the Fail-SafeMBT process model by using MDSafeCer, the recently introduced Model Driven Safety Certification method. By doing so, we provide a threefold contribution: we pioneer the interpretation of DO-331 in academic settings, we validate MDSafeCer in the avionics domain and we strengthen Fail-SafeMBT by providing suggestions aimed at increasing its maturity level.
DO-331是DO-178C的补充，用于基于模型的开发。DO-331是一个基于目标的指南，它定义了一组必须实现的航空软件基于模型开发的目标。该指南还就为实现这些目标而应分别开展和产生的活动和工作产品提出了证据。为了解释为什么收集的证据支持有关目标实现的声明，制造商可以采用基于安全案例的方法。Fail-SafeMBT是一个学术性的，最近被提出的，具有潜在创新性的基于模型的测试过程，需要在航空软件的开发中采用令人信服的论据。为了减少工业环境和学术环境之间的差距，在本文中，我们采用了基于安全案例的方法，并解释了如何半自动地推导合规手段，旨在论证Fail-SafeMBT的合规性。我们的重点仅限于验证计划过程，我们通过创建令人信服的论据片段来部分证明Fail-SafeMBT作为过程证据的充分性。为此，我们首先手动检查Fail-SafeMBT是否包含符合do - 178c / do -331的过程元素，然后根据软件过程工程元模型2.0对Fail-SafeMBT进行建模，然后，我们使用MDSafeCer(最近引入的模型驱动安全认证方法)从Fail-SafeMBT过程模型中导出基于过程的参数。通过这样做，我们提供了三方面的贡献:我们在学术环境中率先解释了DO-331，我们在航空电子领域验证了MDSafeCer，我们通过提供旨在提高其成熟度的建议来加强Fail-SafeMBT。

The article deals with possibilities of utilization of modern industrial sensors for aircraft fuel quantity measurement. The purpose of the fuel quantity measurement in aircraft with either stationary or rotary wings is to provide information about the total amount of fuel and fuel variations under all aircraft attitudes and with all types of fuel. In aircraft technology, there are especially two basic methods of fuel quantity measurement used that are based on measurement of fuel level. Both methods are contact measurement methods and the fuel gauge is always in contact with fuel. The older, easier and cheaper method is based on float level sensors. Modern and more precise method is based on capacitance level sensors. The measured fuel level is then converted to volume or weight of the fuel and displayed on a fuel indicator in the cockpit. Both methods have some limitations and for that reason another fuel level measurement methods have been introduced onboard. Our practical experiments deal with possibilities of COTS ultrasonic sensors utilization for fuel gauging inside small aircraft fuel tank. Ultrasonic fuel level measurement is based on reflecting sound energy at an interface of liquid and air. Tested operating conditions include influence of aircraft attitude changes, mechanical forces changes and temperature changes on whole measuring systems. Fuel volume is also measured by reference capacitance fuel gauge during practical experiments. Experimental results lead to error quantification of COTS ultrasonic fluid level measurement and following technical measures to minimization of systematic errors.

Jeppesen GmbH is researching new communication and interaction systems for the next generation flight deck. One such opportunity is the determination of use cases for wearable technology in support of airline personnel. Key attributes of wearables, pertinent to the ongoing research efforts, include mobility, persistence, ability to be proactive, and context awareness. Wearables also enable hands-free use. The current study attempts to exploit these characteristics to determine their efficacy in the flight deck. The study used a Sony SmartWatch 3 to test two identified use-cases for wearables by delivering Air Traffic Control commands and other flight relevant information graphically and textually to pilots while conducting flights in a simulator setting. These trials were compared with the delivery of the same information via traditional voice instructions and the Controller-Pilot Data Link Communications screen as is integrated in a Boeing 787 auxiliary panel, next to the Primary Flight Display. A preliminary symbology for Air Traffic Control instructions was developed. In the first experiment, instructions depicted on the SmartWatch were evaluated for subjective usability, subjective workload, performance, and effect on pilot situation awareness. In the study, performance was determined by response time, detection of intentionally placed anomalies in, and the correct execution of Air Traffic Control instructions. Performance from instructions displayed graphically and textually on the SmartWatch was not significantly different than on the datalink communications screen. The three aforementioned methods, however, significantly improved response times in comparison with voice communication with Air Traffic Control. The study also determined that a smartwatch is not preferred by pilots for delivering textual Air Traffic Control commands due to the added workload of turning the wrist to view Air Traffic Control messages. In a second experiment, flight-relevant information was provided on the SmartWatch, such as live field winds and Minimum Equipment List items, in reduced visibility, terminal area operations to test acceptance by pilots. This information was considered useful by pilots. Further research needs to be conducted to understand the interactions between information type, information delivery method, and the effects on pilot acceptance. Additional findings of the two-part study include the preference of graphical data over textual information, and for live field winds to be displayed in field of view, when field winds affect the target threshold speed. The implications of this work are two-fold. Firstly, future research should be conducted to expand on and test the identified use cases of wearables in the aviation industry. Additionally, the representation of Air Traffic Control communications graphically should be investigated on other display areas, e.g. Multi-Functional Display, Head-Up Display, and datalink communication sections on a

Since years it is known that radio communication used by ATC can easily be intruded and is therefore subject to recurrent attacks. Nevertheless the voice communication between pilots and air traffic controllers is still the most flexible and efficient medium especially in a busy traffic environment, in non-standard situations or simply when exchanging air-ground messages in plain language is needed. As vulnerability seems not dominant compared to the number of crucial damages, voice communication is still the basic and most important communication method within the aeronautical mobile service. This motivated the development of a prototype called `Secure ATC Communications' (SACom) within the frame of the Global ATM Security Management (GAMMA) Project. The paper at hand describes the required functionalities of the prototype, the validation approach taken, using this security prototype as example, and conclusions for the results of validation, regarding the prototype itself as well as the validation methodology applied to the security context within ATM.

The move from a purely remotely piloted aerial system (RPAS) via air vehicles using automated systems up to a fully autonomous platform is a way that is being followed today. Using automatic take-off and/or landing (ATOL) or waypoint flying, the path towards more complex technologies for RPAS control is clear. Inserting such new technologies into an aerial platform requires extensive testing from an early project phase. Due to the complex nature of environment-related system inputs combined with highly complex algorithms, a pure ground testing will never be able to stimulate those new developments properly. At this point flying testbeds will be used as test vehicles for new equipment operating under real conditions. This paper describes the conceptional design and hardware realization of the datalink system of such a RPAS technology demonstrator testbed for autonomous concepts in the sub-150kg class. Designed light enough to respect certification limitations, this small scale RPAS shall be able to carry realistic avionics hardware undergoing testing in real environment for use as a cheap and flexible testbed. Driven by the concept of flight operations within a dedicated test range and pushed by flight safety a reliable communication system had to be designed to assure a secure conduction and surveillance of the flight, while still being able to interact with the experiments onboard.
