Flight Test Safety Fact, 21-09
Ever wonder what life is like as a hang glider test pilot? (I’m not sure I had that particular thought, but I’ve often imagined what it would be like to fly a hang glider.) This month’s feature article is written

Flight Test Safety Fact, 21-03
If you could travel back in time (something Turbo discusses inside this month’s edition) to continue your work as a flight test professional, but you can’t tell anyone that you are from the future, and further suppose that all you
EASA issues VTOL Means of Compliance Proposal
On 25 May, EASA published document number MOC SC-VTOL Issue 1, “Proposed Means of Compliance with the Special Condition VTOL” on their website. Comments are due by July 24, and I hope our readers will take time to look it
counting is hard, part 2
In the previous post on this topic, we suggested that counting is hard and used the example of counting words in a book. There are three heuristics for communicating uncertainty (3Q) that we will use to help us organize our
counting is hard
On my desk is a novel written by one of my favorite authors. It has a black cover with an image that appears to be the x-ray of a starfish. There are two-hundred and forty three pages in the book,
Machine Learning Techniques Applied to Flight Test Data Evaluation
I mentioned this paper in the Flight Test Safety Fact 19-12 in the limited survey of AI in Flight Test. The authors have generously agreed to share it here. From the authors: This paper proposes an application of machine-learning methods
examples of the build-up approach
The build-up approach is the fundamental safety principle in flight test. Build up from the safest conditions: start from the middle of the envelope in airspeed, altitude, weight & cg. Build-up approach: Take smaller steps as you get closer to
the build-up approach
Ben Luther, a Flight Test Engineer at Gulfstream provides this definition of the Build-up Approach. What is an incremental approach in flight test? I have defined it as being: The creation of cumulative sub-steps within a test program so as
Educating Graduate Engineers on Safety through Flight Testing
Dr. Lorenzo Trainelli The Flight Testing graduate course at the Politecnico di Milano University (PoliMI) is an elective taken in the second (last) year of the Master of Science in Aeronautical Engineering. The aim of the course is to provide
Three Heuristics for Communicating Uncertainty in Flight Test
In Flight Test Safety Fact, 19-09, the Chairman’s column and Rod’s letter raised many questions, but I would like to single in on the question that came to my mind as I read Rod’s email: is Steady Heading Side Slip
