Answer: Flight Characteristics

The aspect ratio of GlobalFlyer is 32.5. The aspect ratio of a wing is defined as the square of the span divided by the wing area. A higher aspect ratio gives a lower drag and a better glide angle. This is a relatively high aspect ratio.

The most efficient angle of attack for best range varies throughout the flight as the aircraft weight changes. It is about 3 degrees at the beginning of the cruise segment and 1 degree at the end.

The wings and tails use custom airfoils designed by aerodynamicist John Ronczof, Gemini Technologies. John also designed the airfoils for the Rutan Voyager and Beech Starship.

GREAT questions, don't stop now!
