Figure 1 shows the emissions of CO2 per person since 1900 and the rise of the world temperature. The increase in world temperature changes the weather, with increased weather-related emergencies in recent years.
January 7, 2021, ©. Leeham News: We finished a 34 article series before Christmas about the enormous work involved to get a new aircraft certified for passenger transport.
It was a background article series to the one we start now, a deeper series on what’s involved in designing air transport vehicles that are less polluting for our environment. We have seen a landslide of such projects in the last years, and from an experienced aircraft designer’s desk, most of these are doomed for failure.
December 17, 2021, ©. Leeham News: As we wrap up the series where we look at the monumental work you have to do to get a new aircraft type certified, we will discuss how we need several aircraft variants, addressing different markets, if we shall survive as an aircraft manufacturer.
All successful aircraft manufacturers produce and market a family of aircraft. If you stay with only one variant, you will find it hard to keep good people as the development work ends.
December 10, 2021, ©. Leeham News: Our aircraft has now achieved its first deliveries and is Entering Into Service (EIS) with our launch customer.
This covers one customer and one jurisdiction. As each country is sovereign in Airworthiness certification, we have work to do for each market we want to address.

Dec. 6, 2021, © Leeham News: Long ago, aircraft were simple, made of steel tubing, wood, and fabric. Engineering staffs were small, and the craftsmen building them had little need for specific production planning instructions because they were very simple. This was the work environment
when CAM4B and CAM 18, the Civil Aeronautics Board Manual 4b and 18, described how aircraft were designed, certified, built, and maintained. Think of Ford Trimotors, Fokker F10, Boeing Model 40s and 80s, and Lockheed Vegas. It was the golden age of air transport.
December 3, 2021, ©. Leeham News: Last week, we went through typical problems by the start of serial production, such as weight creep and traveled work.
Now we discuss the ins and outs of delivering the aircraft to the customer airline and how we support the aircraft’s entry into service.
November 26, 2021, ©. Leeham News: Last week, we started our analysis of the serial production phase. If development is filled with revelations and problems to solve, production has it as well.
We start this week by looking at the beginning of serial production, where several issues are overhangs from development. There are areas of the aircraft, though we have achieved our Type Certificate, that are not quite to the maturity level we want for long-term serial production.
November 12, 2021, ©. Leeham News: Last week, we looked at our role in creating comprehensive crew training so the aircraft can be safely operated during its lifetime.
With maintenance and crew training docs and curriculums well underway we can return to our Flight tests and describe how we finish up the testing and get our Type Certificate.
November 5, 2021, ©. Leeham News: Last week, we looked at our role in creating a competent maintenance activity so our aircraft can be kept airworthy throughout its operational life. The other important part of operational safety is crew training.
We learned that these two parts, keeping the aircraft airworthy with its maintenance and providing adequate training and information to the crews operating the airplane, have a major influence on flight safety. In fact, FAA has found that these parts have a larger influence on flight safety than the aircraft certification regulations.
We, as the OEM, must therefore develop the documentation, curriculum, and training tools so that crews working in the aircraft can fly it safely. This encompasses not only initial training but a continued refresh and check training throughout the crew’s life with the aircraft.
October 29, 2021, ©. Leeham News: Last week, we looked into Instructions for Continued Airworthiness (ICAs), and what roles it plays in air safety.
Equally important for air safety is the qualification and training programs we design for the organizations and people that shall carry out the work with our Instructions for Continued Airworthiness.
