UAS Mishaps and Accidents

 

Like many swiftly advancing technologies, such as unmanned aircraft systems (UAS), the rate of mishaps and accidents can seem relatively elevated. Research indicates that various factors play a role in these drone-related accidents. These encompass human errors, technological anomalies leading to system glitches, and the loss of communication links (affected by environmental factors like interference, signal propagation, and ionosphere energy absorption), among others. Each of these challenges poses substantial risks not only to other aircraft operating in national airspace (NAS) but also to public safety at large.


Byond Visual Line of Sight (BVLOS)

During Beyond Visual Line of Sight (BVLOS) operations, unmanned aircraft systems (UAS) rely on radio frequencies for navigation, connecting to wireless networks. The human operator (HO) needs detailed data on the UAS's bearing, speed, altitude, and position. Additionally, the HO should be able to adjust mission parameters on the go and send ad-hoc commands to the system from either a ground control station (GCS) or a remote station (RS).

With respect to mitigating BVLOS in high-risk situations, there are two tools that can be helpful:

1.    1.0 Automated Collision Avoidance Systems: There are systems on the market (commercial of the shelves (COTS)) that can integrated in to UAS. These devices or systems utilize sensors and algorithms to detect and avoid potential collisions by analyzing the environment around the UAS in real time. This method can significantly reduce the risk of accidents during BVLOS flights.

2.     2.0 Advanced Communication Technologies: By implementing robust and redundant communication systems, such as satellite-based or mesh networks, this method can enhance connectivity and data transfer between the UAS and the ground control station. This ensures more reliable communication during BVLOS operations, reducing the risk of signal loss or disruption.

Automation in Aircraft Systems

Image
 Automation Over the past few decades, automation has transcended its initial applications in manufacturing and extended its reach into sectors like healthcare, transportation, and agriculture. Robotics and autonomy have taken center stage in the development of automated and semi-automated systems, sparking concerns about the replacement of humans in the workforce and the symbiotic relationship between humans and machines in achieving shared objectives. Yet, the extensive use of autonomous functions in both crewed and uncrewed aircraft raises concerns about human operators' reliance on these systems. This dependency often leads to limited understanding of the system functions and reduced control over intervention points for human operators during certain processes.

The ERAU Hub and Configuration Experience

Image
 Introduction This week's project aimed to delve into the aircraft configuration section of the ERAU Virtual Hub to assess the functionalities of prevalent uncrewed aerial systems (UAS) platforms. The Hub simulation demonstrated remarkable user-friendliness, owing much to the detailed tutorial provided. It provides an extensive range of choices for assembling both the uncrewed aerial system (UAS) and the ground control system (GCS), even allowing for the creation of flight plans. This enables a seamless simulation of UAS integration and mission execution. The image below depicts the HUB simulation environment, with the right column offering assembly options for aircraft type and ground control station (GCS).
