Everyday small aircraft and business jets fly safely and effectively with a single pilot behind the control stick in the flight deck.  But, currently large aircraft (e.g., those with a maximum takeoff weight (MTOW) greater than 12,500 lbs), must have at least two pilots in the flight deck to fly the plane.  So, what would it take to be able to certify large Transport Category Aircraft for Single Pilot Operations (SPO)? Well, we’ve just begun a research project for NASA to begin to contribute to answering this question.  In our project, we will explore the processes used to evaluate and certify an airplane design and operations for a particular minimum flight crew (single pilot or crew of two or more).  We will use this information to build an understanding of certification issues and regulatory challenges that would be related to gaining FAA approval for Single Pilot Operations in categories of … Continue reading

Organization of EASA Airworthiness Specifications EASA’s … Continue reading
