Climbing Fast, Sustainably

Just before the monthly Washington Aero Club luncheon—hosted by the National Business Aviation Association (NBAA)—kicked off on Thursday, I was chatting with two members of of the general media whom I had not yet met. One represented Bloomberg’s tax-related publications and was relatively new to the beat. The other reported for the Wall Street Journal’s general business coverage, and had not delved much into private aviation (aside from a stint sitting next to Jon Ostrower while he was still at the WSJ, from whom he said he soaked up aerospace insight like a sponge).

The pair each echoed in their own words the fact they had been invited to a panel on sustainability in business aviation—yet before that moment, had no idea that those flying BA had any desire to act sustainably. “I had no idea anyone flying private jets cared,” was the consensus.

I know in theory how true it is that we often preach to our own choir in BA/GA, but once more I was slapped in the face with proof.

First, kudos to NBAA for bringing these two reporters from the general media (among others) into a room where they would hear an up-to-date and frank accounting from three leaders in our space that sit at the tip of the sustainability spear: Michael Amalfitano, president and CEO of Embraer Executive Jets, Billy Nolen, former deputy FAA Administrator and chief regulatory affairs officer for Archer Aviation, and Scott Lewis, president of World Energy (WE) SupplyZero, one of the largest producers of sustainable aviation fuel in the United States and globally.

In summary, here’s where we are in terms of the three pillars remarked upon by Amalfitano, Nolen, and Lewis—and underlined by moderator Ed Bolen of NBAA:

Commitment from the Manufacturers: Embraer now uptakes weekly the volume of SAF it had delivered quarterly in 2023. Amalfitano noted the Brazilian OEM had tested to 100 percent—”neat”—SAF in its Phenom 300 and Praetor 600, and that it uses the fuel in various blends for test flight, demos, and customer deliveries. “That will allow us to increase what was a low mid-single-digit consumption of SAF to 20 to 25 percent of what we do out of Melbourne” in 2024, he said. Embraer has cooperated with its engine OEM partners, including Honeywell, through the process.

Legislative Synergy for Sourcing and Distribution: Lewis outlined how WE SupplyZero is growing volume at the best rate possible, producing SAF derived from animal fats and used cooking oil. “We are employing latest technology that’s available right now in order to take that up from where we are today,” said Lewis. “About 4,000 barrels a day, of which about 1,000 barrels is sustainable aviation fuel, up to 25,000 barrels a day, of which 20,000 barrels is sustainable aviation fuel.” WE is also working on a pipeline that will deliver from its main terminal in the Los Angeles area (and soon to come in Houston), in order to reduce the overall carbon footprint of the SAF, so that its benefit is not just zero emissions from aircraft exhaust, but through the entire chain. Leaders in the audience noted the passing of the most recent agriculture funding bill in synergy with the last infrastructure funding bills and FAA Reauthorization Act to support biodiesel production in the U.S. The Biden Administration has challenged the industry to produce 3 billion gallons per year of SAF by 2030.

Advanced Air Mobility Goes Electric: Along with Amalfitano, who outlined Embraer’s electric push with its stake in Eve (an electric VTOL), Nolen reported on Archer’s leadership in bringing a viable eVTOL to market, with the regulatory basis established, airline partnerships in play, and a roadmap to infrastructure to support the accelerated development. He brought up another key feature of moving eventually to electric power: the quiet needed to fly within residential communities. “How have we gotten to this point?” said Nolen. “Three critical things have happened. Number one, battery cell technology has gotten us to the point that we have…the carrying capacity. Number two, the FAA has given us a regulatory path to get there. And number three, we’ve had the level of federal investment which, in turn, has unlocked the financial investment.”

All three areas will be required to maintain at least the current pace—and accelerate—in order to continue what BA has managed to accomplish in increased efficiency over the course of the last 40 years. Because the 30 percent greater efficiency gains that we have seen with each new bizjet model over that timeframe aren’t going to be enough to cover the spread in the future.

AERO Takes on Innovation, Part 2

AERO filled its 12 halls with an electric energy, notable on the light end of the market.

And this makes sense, because the show’s DNA lies in ultralights, gliders, balloons, training airplanes—even remote-control models.

Now it has logged 30 “flights,” so to speak, running back to 1977 when it was part of a regional motorsports exhibition, and happening every other year until it became an annual event in a few years back, with a pause for two years for COVID.

When SOCATA first put its TBM 700 prototype on display in 1994, it helped introduce higher-end personal and business aviation into the show. With the presence of Pilatus, Cessna and Beechcraft (now Textron Aviation) in the 2000s, and now Gulfstream with its G500 on display this year—it indicates the importance of this growing B2B show in the marketplace for turboprops and jets.

These aircraft must also meet the industry’s commitment to net-zero emissions by 2050—and interim targets won’t likely be met by pure electric aircraft or those that run on hydrogen.

While Safran’s ENGINeUS motors gain in kWs (and equivalent horsepower) and power storage hits the 800-kW level, our brightest minds still don’t have a good way to translate that power into speed and range—and do it safely.

Case in point: Daher’s EcoPulse project, which places six Safran motors in distributed positions on its TBM-based wings powered via an Airbus storage system—but keeps a Pratt & Whitney PT6A-66D up front. Judging by the flight test profiles I talked about with Daher’s head of design, Christophe Robin, the project is working through a host of problem sets, and it won’t present as a marketable product. In SVP of aircraft Nicolas Chabbert’s update at Sun ’n Fun, and again at AERO, he noted the need to craft a salable solution that would likely look nothing like it. There are constraints and issues associated with flying around carrying that amount of battery power and distributing it safely in an airplane’s joint “cardiovascular” and “nervous” systems that still need sorting through.

Whatever they bring to the table, it won’t be flying on pure electrical power—not to make their self-imposed target date of 2027. And that makes a lot of sense. In talking with Tine Tomažič of Pipistrel, he explained that to get the speed and range you need for a good cross-country mount (such as Pipistrel’s Panthera design), you need the hybrid route for the near future. The battery tech just isn’t there yet.

So we need to keep those turbines running—and on a zero-emission fuel as soon as we can. Pressure looms larger in Europe to meet net-zero goals before 2050. While we didn’t see any protests at AERO from the general public, the specter of them loomed as we headed to Munich for our flight back across the pond. The industry is working diligently towards getting sustainable aviation fuel to the users who have vowed to adopt it—so they can keep projects like the hybrid Panthera and the EcoPulse innovating towards the future.

The way to do this is not to syphon off all the SAF to the airlines at major airports like Amsterdam’s Schipol and Paris-Orly. We can adopt book and claim practices to help offset high prices and availability of SAF to the 2,000 or so airports in the EU that business aviation uses. 

And we can support the development of alternative bio sources for SAF that help increase its volume overall. Projects like Gevo’s intrigue me as cradle-to cradle solutions for utilizing biowaste on a large enough scale to make more than a drop in the bucket. 

And biz av should have primary access to it first—because this is where the skunk works live and thrive.

Jet-A Tax on BizAv?

The recent budget proposal from the White House includes a number of positive points—but one stands to kneecap the aviation industry just as it starts to leave the chocks on sustainability.

That’s the proposed 4X increase (from 22 cents to $1.06/gallon over 5 years) in the fuel tax on Jet-A for bizav operators, a line item that surely resonates with the green set, but bodes poorly for the ability to grow capability, capacity, and jobs under the sustainable aviation umbrella. The quest to net-zero by 2050 absolutely depends on it.

Here are my quick takes:

  1. The healthy flow of sustainable aviation fuel (SAF) into the market relies upon the demand for Jet-A. While commercial aviation represents the bulk of the volume, business aviation has the flexibility and higher margins to accommodate the experimentation required to bring new sources of zero-emission fuel into play. 
  2. The infrastructure investments required to deliver SAF lean on the ability of local FBOs and governments—and distributors—to justify the cost to equip. With lower flowage into these wide-spread locations, the business case grows even more difficult than it already is in some places.
  3. Bringing aircraft production into the U.S.—and keeping what we have—is central to providing skilled labor with well-paying, satisfying work. Keeping sales and delivery volumes to what they reached in the bizav sector before and after the pandemic is vital to offering these desirable positions.
  4. And, at a time when aircraft OEMs fight hard to secure the workforce they need, the ability to appeal to the younger generation with sustainable aviation projects is critical to attracting the brightest minds to our industry. They want to be part of the solution. Raising the tax on one sector that provides some of the coolest jobs in aviation—across the board from engineers to marketers—is at best shortsighted and at worst a true crux for the industry.
