The Small Airliner problem, Part 2
Subscription required
By Bjorn Fehrm
April 27, 2023, © Leeham News: We started a series about the viability of the business plans for small airliners (nine to 50 seats) last week in the light of a continuing decline of regional airlines in the US and Europe.
To understand whether fundamentals are stacked against small airliners, we look at operational cost factors and how these scale with aircraft size. Then we add the revenue and yield and discuss the conditions for viable business plans for different size aircraft.
This week we use the Leeham airliner performance and cost model to compare the airframe energy and fuel consumptions for airliners spanning nine to 200 seats.

Summary:
- On an airframe energy level, a smaller airliner consumes more energy per transported passenger than a larger one.
- If we change the metric to propulsion energy consumption, the trend is augmented as small propulsion solutions are less efficient than larger ones.
Embraer deliveries surge; executives proclaim rebound from Covid, failed merger

March 13, 2023, © Leeham News — Embraer executives said last week that the company is on a flight path to growth after weathering two major storms in 2020.
“As we have said, since 2020, the 2021 and 2022 years would be dedicated to the business recovery after two simultaneous crises – the pandemic and the end of the Boeing deal – and the focus will be on growth from 2023,” Embraer CEO Francisco Gomes Neto said Friday.
“We can now state we have fulfilled what was promised,” he continued. “The business turnaround was completed in 2022, and we are ready to start a new growth phase.”
Embraer still faces “supply chain challenges this year,” he acknowledged, “but we are optimistic about the company’s future in terms of revenue growth and profitability.”
Neto made the declaration as his company reported delivering 80 regional and executive jets in the fourth quarter of 2022, which was roughly half of the total deliveries for the year.
The company reported earnings before interest and taxes of US $166.2 million for the quarter, which was 196% better than its earnings in the same quarter of 2021.
- Embraer sees orders recovery
- China is one of two promising markets
- Business jet market ‘very robust’
- Continued investment in decarbonization

Bjorn’s Corner: Sustainable Air Transport. Part 58. Summary Part 2.
By Bjorn Fehrm
February 17, 2023, ©. Leeham News: Last week, we summarized that SAF is the short-term solution for GreenHouse Gas (GHG) reduction for Air Transport, and hydrogen is the longer-term solution for up to medium-haul flights.
What about battery and hybrid aircraft? It’s the go-to solution for ground transport (except for long-haul trucks, which are going hydrogen, Figure 1)?

What is the ticket price influence of SAF? Part 2

By Bjorn Fehrm
Feb. 16, 2023, © Leeham News: Last week, we looked at the ticket price influence if airline fuel costs would increase going forward, either through increased use of Sustainable Aviation Fuel, SAF, or higher environmental emission fees.
We realized that ticket prices have other parts than fuel and aircraft-related costs. For instance, an airline has sales and marketing, administration, and airport ground staff. We got an overview of such cost parts depending on whether the airline was a mainline carrier or a Low-Cost Carrier (LCC).
Now we use this knowledge and our airliner performance and cost model to check the influence of varying fuel and emission costs on ticket prices going forward.

Summary:
- We check the influence of SAF blends and EU emission permits on end-of-decade energy costs.
- Then we discuss how increased flight energy costs can influence ticket pricing.
What would be the ticket price influence of SAF?

Feb. 9, 2023, © Leeham News: I have the last weeks described the difference between Jet fuel and SAF, or Sustainable Aviation Fuel, in my Friday Corners. We could see it has emission advantages compared with fossil Jet fuel that goes beyond the CO2 reductions it offers.
It’s a cleaner fuel where the production methods can avoid the troublesome aromatic carbon molecules that causes soot to form in jet engine exhaust. With reduced soot, the generation of contrails reduces, which is beneficial for reducing global warming.
But we could also see that SAF should be costlier to produce as the production cycle is complete. Our fossil fuel’s raw material had their CO2-absorbing plant growth millions of years ago.
So, if we mix SAF into Jet fuel at different ratios, what will be the effect on ticket prices? How much more expensive would flying be when we use SAF or other measures like CO2 emission taxes are introduced? We use our airliner performance and cost model to find out.

Summary:
- In addition to the aircraft operating costs, we must add other airline costs to understand ticket prices.
- Then we must look at the effects of revenue management and the type of flight, domestic or long-range.
Bjorn’s Corner: Sustainable Air Transport. Part 56. SAF non-CO2 effects
By Bjorn Fehrm
February 3, 2023, ©. Leeham News: We’ve gone through the composition of Sustainable Aviation Fuel, SAF, its production, and its cost. We’ve also discussed its effect on CO2 emissions from Air Transport.
An important part of SAF’s advantages is its effect on non-CO2 emissions. It stems from its low content of Sulphur and Aromatic hydrocarbons.

Bjorn’s Corner: Sustainable Air Transport. Part 55. Sustainable Aviation Fuel feedstocks
By Bjorn Fehrm
January 27, 2023, ©. Leeham News: Last week, we learned the main pathways to Sustainable Aviation Fuel and their production volumes for the next years.
Now we look at the feedstocks, what output we get from these, and how to safeguard the pathway is ethical and sustainable. Finally, we look at the cost of SAF until 2050.

Bjorn’s Corner: Sustainable Air Transport. Part 54. Sustainable Aviation Fuel Production
By Bjorn Fehrm
January 20, 2023, ©. Leeham News: Having introduced Sustainable Aviation Fuel, SAF, as essential for reducing Green House Gases (GHG) until 2050, we now look at how SAF is produced, what pathways from feedstock to SAF are the main ones, and what are the short and long-term potentials of the different pathways.
I was helped to grasp the area by Neste’s EVP of Renewable Aviation fuel, Thorsten Lange, who, after we met when he presented at the Airbus Summit in November (Neste is a leading SAF producer), took the time to explain the subject to me last week. He also recommended a report we use to understand SAF.

2023 outlook for Sustainable Aviation
Subscription required
By Bjorn Fehrm
Jan. 16, 2023, © Leeham News: In the years from 2015, Sustainable Aviation awareness has grown from “something interesting, but will it be needed?” to “how do we fix the environmental issues we have fast enough.” Scientists saw what happened 20 years ago, but the general public didn’t react until it affected everyday life.
The development of more Sustainable Aviation solutions has taken a similar route. Until 2015 the changes to morph aviation into a more sustainable path were a scientific discussion. At Le Bourget Air Show 2015, Airbus presented the E-Fan (Figure 1) that would cross the English Channel the following month. It started an intense debate about sustainable propulsion concepts for aircraft.
Eight years later, where are we today, and what will happen in 2023?

Summary:
- The year will witness the “separation of the wheat from the chaff.” Viable concepts will prove themselves, and thin concepts, technically or funding-wise, will fail.
- We have a number of first flights from interesting projects. Several are in the “wheat” category.
Bjorn’s Corner: Sustainable Air Transport. Part 53. Sustainable Aviation Fuel
By Bjorn Fehrm.
January 13, 2023, ©. Leeham News: Last week, we could see in an example how effective Sustainable Aviation Fuel, SAF, blended into our regular Jet fuel, would be in reducing CO2 emissions until 2050.
It’s the only technology that can substantially influence our emissions over the next 30 years, as alternate technologies like hydrogen-fueled airliners need to ramp to thousands of aircraft before it affects emissions.
To understand SAF and how it can be produced and blended into Jet fuel, we first need to understand what Jet fuel is.
