Introducing the Celera 500L.
Built. Flown. Proven.

The Celera 500L is the most fuel efficient, commercially viable aircraft in existence. With 31 successful test flights performed, Otto Aviation is ushering in a new era of aviation through paradigm shifting performance and economics.


“Innovation at its core is solving a problem without conventional bias.” – William Otto, founder and CEO of Otto Aviation.

Otto Aviation’s goal is to create a private aircraft that allows for direct flights between any city pair in the U.S. at speeds and cost comparable to commercial air travel. This takes a complete reinvention of how we fly and an unprecedented look at what private aviation can be.

When you put the best of everything into one plane

William Otto has always taken the road less traveled when it comes to approaching a new design concept. He knew that to radically change an aircraft’s performance there would have to be changes made to conventional aircraft architecture. This clean-sheet, first principles approach has led to an aircraft that not only excels in comfort, range and speed but also drastically reduces aviation’s carbon footprint.


All current test flight data supports the projected performance of the aircraft.

The full-scale prototype has over 35 hours of flight test time. The majority of these hours have been validating performance at higher altitudes in a clean flaps-up / gear-up configuration.

Production Quality Tooling complete for all major aircraft parts. Tooling built and tested to meet laminar flow tolerance requirements.

Manufacturing processes proven, certifiable materials selected and compliant documentation generated in anticipation of FAA certification.

The USPTO has granted 7 patents on the design of the Celera 500L.

Today the 500l, Tomorrow the 1000l, hybrid and drone
