Trajectory Based Operations – TBO: The Next Frontier in Flight Operations


By Dana Knight, Product Director at eTT Aviation


In the continuously evolving world of aviation, staying ahead means not only adapting to changes but also paving the way for them. As we explore the next frontier in flight operations, Trajectory Based Operations emerges as a pivotal innovation, set to revolutionize how we approach the skies. This concept, while complex, promises to enhance efficiency, safety, and environmental sustainability in airline operations.



Understanding TBO


At its core, trajectory management involves the precise planning and control of the flight path of an aircraft from takeoff to landing. Unlike traditional methods, which often involve a more segmented approach to navigation and flight adjustment, trajectory management seeks to create a seamless and optimized flight trajectory that considers various factors such as weather, airspace restrictions, and aircraft performance capabilities.Gate to Gate trajectories are created prior to departure and include all four dimensions of the flight – position (latitude/longitude), altitude and time.  Given this information for all flights that plan to operate, Air Traffic Management can better forecast demand and plan accordingly.


This holistic approach that accounts  for real-time adjustments and more accurate predictions, making it possible to optimize each phase of the flight. The benefits of such a system are multifold: from reducing fuel burn and emissions to improving flight punctuality and decreasing airspace congestion.


The push for TBO comes at a critical time. As air traffic continues to grow, the global aviation community faces pressing challenges related to environmental impact, airspace capacity, and operational efficiency. Here, trajectory management is not just beneficial but necessary.


Why TBO Matters Now

  1. Environmental Sustainability: Aviation is a significant contributor to global carbon emissions. Efficient trajectory management can minimize unnecessary fuel consumption, substantially reducing an aircraft’s environmental footprint.

  2. Enhanced Safety: By improving the predictability of flight paths, trajectory management also enhances the safety of air travel. More predictable and optimized routes reduce the potential for conflicts and allow for better airspace management.

  3. Increased Efficiency: For airlines, operational efficiency is directly tied to cost savings. Trajectory management enables flights to operate on the most efficient routes in real-time, considering unexpected factors like sudden weather changes or airspace congestion. This leads to less fuel usage, fewer delays, and lower operational costs.


eTT Aviation’s Role in Shaping the Future


At eTT Aviation, we are committed to leading the charge in adopting and refining trajectory management technologies. Our flight planning and management systems are designed to integrate advanced trajectory management capabilities, providing our airline partners with the tools they need to provide the TBO information needed to provide Air Traffic Management.

We are also closely engaged with regulatory bodies and international aviation communities to standardize trajectory management practices and ensure they can be adopted seamlessly worldwide. This collaborative approach not only enhances our systems but also contributes to the global advancement of aviation technology.


Looking Ahead


The journey towards widespread adoption of TBO is just beginning. As we continue to develop and refine these technologies, the cooperation of the entire aviation ecosystem — from technology providers like eTT Aviation to airlines, airports, and regulatory authorities — will be crucial.  The amount of airspace that we have to operate in is fixed, we have to find more efficient ways to utilize the scarce resource.


Innovation in trajectory management represents a step toward smarter, more responsible air travel. It’s an exciting time to be part of this industry, as we work together to ensure that the future of aviation is as bright as it is boundless.


At eTT Aviation, we’re not just adapting to changes in the world of flight operations — we’re driving them. As we look to the horizon, trajectory management stands out as a key area where we can make a significant impact, promising a future where air travel is safer, cleaner, and more efficient. Let’s navigate this next frontier together, optimizing the skies for generations to come.
