Angry Birds: eVTOLs Need a Standard to Certify Vulnerabilities from Bird Strikes
More than 90% of bird strikes occur at 3,000 feet above ground level — precisely where most eVTOLs will fly.
In Urban Air Mobility – Especially in Urban Air Mobility – Time Is Money
Your pax are onboard, you departed on-time. Your route was clear, weather was perfect and then – a geofence gets put up literally out of the clear blue sky. You want to minimize your snap trajectory and your trajectory but that’s easier said than done. Or it was, until a cohort of researchers from Cranfield…
Urban Air Mobility Will Stretch Pilot Fatigue Management in New Ways
Imagine yourself a taxi driver in New York City, London, Berlin, or Tokyo; dozens, maybe hundreds of trips in an 8-, 10-, maybe even 12-hour day. You’re doing what you can, as the movie Cabaret song said, to “earn a mark, a yen, a buck, or a pound.” Now, flash-forward to 2027 or 2030 and…
How Much Noise Will a Single Rotor Make When a Single Rotor Makes Noise?
In their paper, “Best Practices for Predicting Acoustics of a Single Rotor Using the NASA RVLT Conceptual Design Toolchain” presented at the Vertical Flight Society’s 6th Decennial Aeromechanics Specialists’ Conference held in Santa Clara, California in February 2024, NASA aerospace engineers Lauren Weist, Natasha Schatzman, and Dorsa Shirazi detailed the results of their study intended…

Urban Air Mobility: When It Comes to the Public’s eVTOL Attitudes, It’s Six of One, Half a Dozen of the Other
The March 2024 Issue of Transportation Research Interdisciplinary Perspectives published on Science Direct offers some advanced perspective on how the public-at-large will cotton to this whole ‘flying cars’ thing about to be unleashed on them (It’s kind of a ‘ready-or-not’ here we come kind of thing.). Researchers from Technische Universität Berlin, Hamid Mostofi, Tobias Biehle, Robin Kellermann, and Hans-Liudger Dienel presented their…
