Varon Vehicles’ fifth think tank on Urban Air Mobility in Latin America continues to cover key industry topics
Another great panel of speakers came together for Varon Vehicles’ latest think tank about the implementation of Urban Air Mobility in Latin America, which this time focused on Latin American cities.
Since the first session was held at the start of August, each one-hour session aims to bring stakeholders from across the industry into conversations on a range of topics, including vertiports, airspace integration, regulations and public adoption.
Joining the discussion for this think tank was James Sherman, Director of Strategic Development at the Vertical Flight Society, Luis Alonso, Research Scientist in the City Science group at the Massachusetts Institute of Technology (MIT), David Russell, Co-Founder and CTO of Airio, Jared Esselman, Principal of Aerial Transportation Solutions, and Simon Briceno, Head of Advanced Air Mobility at Jaunt Air Mobility.
During the hour, the panel talked about Urban Geodesics, Users Fear Barrier / Safety Perception, Impacts on General Mobility, Air Vehicles Density Expectation and Electric Grid Sourcing Availability.
Moderating the session, Felipe Varon, Founder and CEO of Varon Vehicles, said: “We want to talk about the overall reason why we are implementing Urban Air Mobility in the first place. What are we trying achieve? We have to take in an urban perspective, a city point of view, to answer that question. What types of problems are we trying to tackle and what are the impacts we expect to see, be them both positive and negative in our cities.”
Varon also started off the conversation by introducing Urban Geodesics, which is defined as the shortest path between two vertiports in the urban or mobility scenario.
“When we design these airspace volumes between vertiports, we have to take into account no-fly zones, weather conditions, topography and other known variables low-altitude aerospace over a city to design these lanes. The urban geodesic is a tool that helps us organise traffic as we design urban air mobility for the city.”
Talking first about urban geodesics was Russell, who said: “This is a fairly well understood problem that can be handled in two different ways. When we’re dealing with one vehicle and its particular flight path, we generally build a three-dimensional models of the area where it is going to pass, and then we define that particular variable.
“In this case, we’re defining a more permanent structure so we can take more time to do that. There can be optimisation routes which can be brought to bear and there are auto-routing types of routines, but they are all based on cost function. That’s where you define the variables that are going to impact whether it’s good or bad.
“In terms of good, you want to minimise distance, but that might come at the cost of how many times I have to change directions or altitudes. Do I want to avoid flying over schools, or enhance flying over railroads, cars or other items.
“By creating the entire list of variables, we can measure in a 10 metre grid throughout the area we can then do either an optimisation sweep use a simple metric search — which asks if you want the best solution, or getting one of maybe a hundred good solutions. It’s fairly easy to solve this problem, especially since you’re only looking for one real track with a lot of definitions.”
Briceno expanded on Russell’s points about the urban geodesic, adding that he mentioned all the key inputs to designing these routes.
“It’s definitely very critical from an operator’s or aircraft standpoint. Some of those points will include the flight profile that is specific in some ways to the aircraft from a performance standpoint, the approach and departure procedures. As you fly lower to the ground, there’s going to be a really important need to understand all the topography and obstacles.
“It’s not just about having a good understanding of what to avoid on the ground, but to ensure that over time we know that the model is updated and we now that quite well with helicopter operations and powerlines, that it’s a big concern with them flying low to the ground. As we design these geodesics in cities that are constantly growing and building new buildings, it’s important we take into account the beginning and throughout the whole operating life cycle as well.”
Next to speak was Esselman, who in his role at Aerial Transportation Solutions, is leading an eco-system in Utah. Varon asked his what his point of view was in terms of the impact we are expecting from Urban Air Mobility in cities.
Esselman said: “I love the idea of geodesics. For Utah, we took our virtual lanes and said what’s politically pallatable? How do we connect these intermodal points, what’s feasible and what is politically accepted by the people?
“We found taking the road map and elevating it by 4, 6, 800ft. They already accept transportation along these routes, and accept that as a noise and pollution conduit. But one of the things we know that has to evolve is as buildings and cities grow, we have to take into account for FAA purposes, the Part 77 Services of those intermodal landing takeoff operation points.
“As an ecosystem, we don’t want to prevent new buildings coming in, but want to design new approach and departure paths into those geodesics to allow for that new construction to continue, and still operate a seamless Urban Air Mobility environment.”
Alonso agreed with the points Esselmann said about inter-modal connections between different mobility choices, and that he thinks flying cars will be another option.
“I think as city planners, we always think about different ‘what if’ scenarios and have the same issues with autonomous vehicles. If we look into the next 100 years, maybe all of the vehicles will be autonomous. It doesn’t matter if they are flying or in the middle of the road.
But I’d like to look into the other extreme scenario where maybe in less than 100 years — perhaps 50 — cars are going to be flying and how is that going to shape the city. We are going to have what architects call ‘Vertical Cities’ and this kind of multi-modal infrastructure is going to be needed in a way that is also vertical, because when you shift from a bus to a tier station you have to move in a vertical direction, and that’s already a challenge in some cities.
“I’m also very interested in privacy issues as well, depending on how high the flight is. So maybe they could fly at the same height as the buildings. As a city planner, the idea of thinking how these vertical cities are going to be is amazing, what are the streets going to look like if we remove the cars. Will they be just for humans, or are we going to have different levels in the city? It’s very exciting and opens up a long conversation.”
Giving his thoughts, Sherman agreed that defining specific routes is a great idea and allows metrics to be taken along the way to see how the first aircrafts introduced are doing. But he advised that caution needs to be met as not all of the aircraft will be travelling at the same speed.
“You’ve got the Jaunt Air Mobility vehicle which will travel at a certain envelope at a certain speed, and then the Joby one travelling alongside it might be a bit faster, so we need to monitor how those routes are defined. I like the idea of defining routes along pre-defined transportation network, which is a good thing.
“We have a lot of community issues to deal with and noise is one of them, so if we start off where there is a fair amount of ambient noise, we kind of fall into the background noise so that’s going to key for getting public acceptance. That also helps to reduce some of the risk on the ground too.
“As much as we want to put 10 to the minus 9 safety on these vehicles themselves, there are some additional risks and there will be the likelihood of some crashes. Putting these vehicle routes over areas where we limit the risk is going to be a key aspect.
“And it’s also how we manage these routes from other unintended consequences — we have a significant number of drones flying, how do we keep them out of our space or at least avoid them along the way. There’s a lot of good things we need to talk about, and also a lot of risks that need to be addressed, and starting with defined routes is a very good way to do that.”
The next think tank will be on Friday, 2nd October from 12noon to 1pm EDT, and focus on Innovations in Insurance. To register for this session, and watch the full recordings of previous think tanks, visit www.varonvehicles.com/skyscraper.
