What Is a Flat Spin?

Pilot Institute

PARE: Power idle, Ailerons neutral, Rudder opposite, Elevator forward. Ailerons: Neutral. The problem is that the airflow from the propeller goes over the horizontal stabilizer, which produces a downward force (and causes the nose to pitch up). The movement of the ailerons will change the angle of attack of both wings.

Split-S Decision

Plane and Pilot

Alongside a nearby highway, some recognizable bits of airplane, the vertical stabilizer and rudder, a horizontal stabilizer and elevator, fell separately to Earth. I did my first aileron roll in an RV-4. The pilot died instantly. Nevertheless, the NTSB is clear.

What Is a Dutch Roll, and Is It Dangerous?

Pilot Institute

Placing the center of gravity ahead of the aircraft’s center of lift improves longitudinal stability. The aircraft’s horizontal stabilizer (tailplane) creates a downward lift to counterbalance pitching moments. Directional Stability Directional stability decides how stable the aircraft is about the yaw axis.

Nothing Small About It

Plane and Pilot

The wing’s dead-smooth surface plus the tight-fitting aileron and flap brackets plus aileron gap seals give the build a professional factory look (left). Just recognizable in the background is a horizontal stabilizer and one-piece elevator. The old Grummans are, sadly, near extinction in workable form today.

Return to Form

Plane and Pilot

General aviation is driven by myriad forces. Planespotters note the F2’s separate ailerons and flaps, conventional tail. The previous CTs had a stabilator for pitch, where the new F2 uses a more conventional elevator and fixed horizontal stabilizer. Then theres the sales and marketing footprint.
