35 years ago: How a United Airlines crew landed an ‘unflyable’ DC-10

Aerotime

The primary flight controls on the DC-10 (ailerons, rudder, elevators, spoilers) were all operated by hydraulic pressure and the first officer was quick to realize that his controls were unresponsive to his inputs. On checking the hydraulic fluid pressure and quantity gauges, he noticed that they all read zero.

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.

Today In Aviation History: First Flight of the Northrop X-4 Bantam

Vintage Aviation News

The X-4 had no horizontal stabilizer in order to avoid interaction of shockwaves between the wings but had a vertical stabilizer and rudder. For better maintenance access, the small tail of the aircraft could be removed to work on or remove the engines.

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.
