Navigating the Unknowns: How FlightOps Revolutionizes BVLOS Flight Operations


Introduction

In the rapidly evolving world of unmanned aerial systems (UAS), Beyond Visual Line of Sight (BVLOS) operations represent the frontier of innovation and opportunity. However, venturing beyond the pilot's direct line of sight introduces a set of challenges and "Unknowns" that can complicate flight missions. From maintaining communication over long distances to navigating complex terrains and dynamic airspace, BVLOS flights require a new approach to ensure safety and efficiency. This is where FlightOps enters the scene, designed from the ground up to address these very challenges. But what exactly makes BVLOS operations so complex, and how does FlightOps mitigate these "unknowns"? Let's dive into the world of BVLOS and discover how technology is paving the way for safer, more reliable flights.


The Five Unknowns of BVLOS Flights

Before we can appreciate the innovations brought forth by FlightOps, we must first understand the fundamental challenges of BVLOS flights. These challenges, or "Unknowns," include:

  • Communication Stability: The risk of losing communication, which can leave operators blind to the UAS's status and unable to influence the mission.

  • Terrain and Surface Coverage: The need to navigate around natural and man-made obstacles without the advantage of direct sight.

  • Dynamic Nature of the Airspace: The unpredictability of encountering other aircraft, which could necessitate real-time flight adjustments.

  • Environmental Conditions: The impact of weather and other environmental factors that can change unpredictably during a flight.

  • Energy Management: The requirement to balance energy consumption with the need to complete the mission safely.


Communication Stability: Navigating the First Unknown

One of the most significant challenges in BVLOS operations is ensuring stable communication between the UAS and the operator. Traditional line-of-sight flying relies heavily on direct visual contact, which is not possible in BVLOS flights. As the distance increases, so does the risk of losing connection, whether due to terrain interference, signal degradation, or other factors. This loss of communication is not merely an inconvenience; it poses a real risk to the mission's success and the UAS's safety.

 

Terrain and Surface Coverage: Understanding the Second Unknown

Beyond the reach of the operator's eyes lies a landscape filled with potential hazards. Mountains, trees, buildings, and power lines can all threaten the safety of a UAS during a BVLOS flight. Navigating this complex terrain requires advanced planning tools capable of considering these obstacles over long distances and intricate routes. Without direct visual confirmation, the operator must rely entirely on these tools to avoid collisions and ensure a safe flight path.

 

Dynamic Nature of the Airspace: Facing the Third Unknown

The airspace is a busy, ever-changing environment. During a BVLOS flight, a UAS may encounter low-flying aircraft, helicopters, or even other drones. Each of these encounters represents a potential threat that must be avoided to maintain safety. The challenge lies in the inability to predict these encounters and the need for the UAS to adapt in real-time, altering its flight path as necessary to avoid conflicts.


Environmental Conditions: Confronting the Fourth Unknown

Environmental factors such as weather, population density, and temperature can significantly affect the performance and safety of a BVLOS flight. Conditions that were clear at takeoff can rapidly change, introducing new challenges such as reduced battery efficiency in cold weather or altered flight dynamics in strong winds. These environmental changes can occur without warning, making it critical for BVLOS operations to incorporate real-time environmental data and adapt the flight plan accordingly.

 

Energy Management: Tackling the Fifth Unknown

Energy management is a cornerstone of successful BVLOS operations. Long-distance flights require careful planning to ensure the unmanned aerial vehicle (UAV) has sufficient power to complete the mission and return safely. This becomes even more complex when considering variables such as wind resistance, payload weight, and battery health. An unexpected detour or extended flight time due to adverse conditions can drastically alter energy consumption rates, making precise and dynamic energy management essential.


 

Mitigating the Unknowns: The FlightOps Solution

FlightOps is designed to address the challenges posed by the five "Unknowns" of BVLOS operations. By equipping UAVs with advanced computational power and algorithms, FlightOps provides a comprehensive solution that enhances safety, reliability, and efficiency. Let’s explore how FlightOps tackles each unknown:

 

The Onboard "Robot-Pilot": Automating Decision Making

At the heart of the FlightOps system is the onboard "robot-pilot," a sophisticated compute platform that automates the flight planning and decision-making processes. This system reduces the reliance on constant communication by enabling the UAV to respond autonomously to various scenarios. Whether it’s recalculating a route due to a newly detected obstacle or adjusting to unexpected communication loss, the robot-pilot ensures that the UAV can continue its mission safely and effectively, even in the absence of direct operator control.

 


Automated Routing and Terrain Navigation

FlightOps simplifies the complex task of route planning, especially when navigating close to the ground and around obstacles. By automating the routing process, the system ensures precision flight paths that are continuously validated against the latest data. This means that if the terrain or obstacle information changes while the UAV is in flight, FlightOps can dynamically adjust the flight plan, enhancing safety and mission success.

 

Airspace Integration for Safer Flights

Integrating seamlessly with airspace data, FlightOps enables UAVs to react quickly to the dynamic nature of the airspace. When a potential conflict with manned aviation or another UAV is detected through ADSB, a UTM system or Radar, FlightOps rapidly recalculates the flight plan to avoid the intruder and maintain a safe distance. This capability is critical for preventing mid-air collisions and ensuring that BVLOS operations do not interfere with existing airspace users.

 

Adapting to the Ever-Changing Environment

FlightOps leverages real-time data inputs, such as micro-weather information and population density maps, to adapt flight plans on the fly. This allows the UAV to respond to changing environmental conditions, minimizing risks associated with weather changes or unexpected ground hazards. By integrating these data sources, FlightOps ensures that UAVs can operate safely and efficiently, even in rapidly changing circumstances.
