One effect of a rotating propellor: It acts as a gyroscope. What does this mean for the pilot?

Thrust-line adjustment is a powerful tool for tailoring flying qualities, but it’s complicated.

Once designers had addressed every other drag-producing aspect of the biplane, they decided to get rid of the struts and wires bracing the wings—and the switch to the monoplane was made.
Wind Tunnel
Today, monoplanes dominate, but biplanes came first. They had their advantages—and for some of today’s missions, they still do.
Wind Tunnel
Nine simple rules, distilled from years of experience (making—and fixing—assorted mistakes), can help any aircraft designer avoid disaster.
Wind Tunnel
It’s all about lift, and knowing your airplane’s lift margin at a given airspeed tells you what the airplane is capable of.
Wind Tunnel
Contrary to popular belief, the frontal area of an airplane is not the most important determinant of drag.
Vortex Generators and STOL Performance
One way to solve the problem of flow separation—and stall—is by installing vortex generators on your kit aircraft.

While two-control airplanes were designed to make a pilot’s life simpler, they come with significant compromises.

Bob Fritz presses on! In this installment, he powers up the Grand Rapids Technologies EFIS panel, solves a curious com antenna problem, installs the Zaon PCAS, fits the door to the fuselage’s curvature, and streamlines the air flow to the oil cooler.
Mini Satcoms
The short list includes considering how, where and why you’ll use the device, plus app interfaces and data costs. SPOT and Garmin are standouts.
