The trim on the horizontalstabilizer – the rear wing of the aircraft – was not working. Then the tone indicating the movement of the horizontalstabilizer sounded. The aircrafts horizontalstabilizer had pitched to 3.6 As such, Tansky had to rely on elevators alone to climb to 31,000 feet.
Parts that have been salvaged in the last 48 hours include the right wing, center fuselage, part of the left wing and left fuselage, significant portions of the forward cabin and cockpit, vertical and horizontalstabilizers, tail cone, rudder, elevators, TCAS computer and quick access recorder.
(image via AirCorps Aviation) The larger, freshly painted parts shown here include the brake cylinders (lower left center), brake pedals above them, the vertical stabilizer fairing on the near right center, and the horizontalstabilizers center tube on the far right. The landing gear components were test-fitted before painting.
The restoration team removed, refurbished (or remade) and reinstalled each component from the original vertical stabilizer, one-at-a-time, so everything stayed in alignment, negating the need for a fixture. AirCorps Aviation’s CAD department has produced a rendering of the AT-10’s horizontalstabilizer.
However, the wooden rudder and elevators need repairs due to warpage and tears, respectively. The wings, horizontalstabilizer, and elevators will be removable in 30 minutes, as the museum plans on using the original trailer, which it received with the project, to transport it to schools and airshows as part of a STEM program.
(image via AirCorps Aviation) The fuselage has been moved to another area of the workshop to make room in the woodworking area for restoring the wing center section and the horizontalstabilizer. The rudder hinges have been installed. image via AirCorps Aviation) Here is the vertical with the rudder frame attached.
D-558-2 Skyrocket take off using JATO assist in 1949 NACA engineers improved the rockets performance by adding nozzle extensions to its combustion chambers, reducing exhaust interference with the rudders and increasing thrust at altitude. They also chilled the alcohol fuel and waxed the aircrafts fuselage to reduce drag for a record attempt.
The most significant visual differences were the T-46’s high wing and the “H” tail, with twin vertical stabilizers mounted to the ends of the horizontalstabilizer that strongly resembled those of the company’s previous jet, the A-10 Thunderbolt II.
A short 18 months later, on August 13, 1937, the XPB2Y-1 took to the skies for the first time, revealing plenty of room for improvement lateral instability was a major problem for the deep-hulled boat, so the single tail fin was augmented by two smaller fins on the horizontalstabilizers.
Photo by NASA The impetus for the program came from issues the Navy had encountered with inadvertent spin entries, which were traced back to the aircrafts aileron rudder interconnect system. In response, the NASA/Navy/Grumman team developed and tested four different configurations of the system to mitigate the problem.
Noting that the application of fertilizer and other chemicals often corroded a conventional tail, Pellarini simply attached two tail booms that each carried its own horizontalstabilizer and elevator. The fuselage is 9 feet tall, just about even with the top of the twin rudders.

Clear and straight grain is necessary in this application.
All of these primary control surfaces serve as a horizontalstabilizer for the plane. You’ll find a horizontalstabilizer, vertical stabilizer, elevator, and rudder pedals here. Trim tab: The aileron and trim tab work together to counteract any aerodynamic force the plane encounters.
However, if you take a close look at the inboard upper wing surface of the B-52, you will see a neat row of vortex generators that correspond to the width of the horizontalstabilizer. These were added to manage the low speed air flow over the wings, stabilizer and elevators.
The X-4 had no horizontalstabilizer 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.
Contemporary postcard showing Louis Bleriot flying the Bleriot VIII, a forerunner to the Bleriot XI (Wikimedia Commons) By 1908, Blriot developed the Blriot VIII, the first airplane to combine a hand-operated joystick for the aircraft’s pitch and roll axis and foot-operated rudder controls for the yaw axis.
Short-coupled with a large horizontalstabilizer, the aircraft was practically a staggered biplane. Pitch was controlled by varying the angle of incidence of the upper wing (forward and aft motions of the stick) and roll was initiated by the oversize rudder (left-right motion of the stick).
PARE: Power idle, Ailerons neutral, Rudder opposite, Elevator forward. Rudder: Full opposite input to the spin direction. The problem is that the airflow from the propeller goes over the horizontalstabilizer, which produces a downward force (and causes the nose to pitch up). Ready to become a safer pilot?
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.
9” on its rudder. Albree accepted the proposal, and work began on what would become the Model PG Pursuit (alternatively called the Model U-2), which was marked as the “Albree No.9” Timson had designed nearly ten years prior.
Alongside a nearby highway, some recognizable bits of airplane, the vertical stabilizer and rudder, a horizontalstabilizer and elevator, fell separately to Earth. The breakup started with rudder flutter. The pilot died instantly. This sequence of events was confirmed by further review of security camera footage.

Placing the center of gravity ahead of the aircraft’s center of lift improves longitudinal stability. The aircraft’s horizontalstabilizer (tailplane) creates a downward lift to counterbalance pitching moments. Directional Stability Directional stability decides how stable the aircraft is about the yaw axis.
The turbulent air hits the horizontalstabilizer, which causes a vibration that can be felt throughout the aircraft. This requires rudder input to maintain directional control. You should always test the stall warning system on the ground to ensure it works. Buffeting is like flying in rough, choppy air.
The previous CTs had a stabilator for pitch, where the new F2 uses a more conventional elevator and fixed horizontalstabilizer. With the F2, the rudder and vertical stabilizer are changed, with the rudder becoming a much smaller surface than before. Well see about that. In this case, nothing.
An elegantly simple rope system inside the fuselage raises and lowers the Gweduck’s water rudder mounted inside the base of the main rudder (right). From the pilot’s seat it cruises near effortlessly and handles nimbly on land or water with a great combination of stability and modest control pressures. So what would I fix?
Both the vertical and horizontalstabilizers were made of wood and fabric, while the construction of the wing involved wooden spars and ribs, with metal leading edges inboard of the engine nacelles, plywood leading edges on the outer panels, and doped fabric on the trailing section.
The panel showed a Rudder Limiter Fault advisory but rather than consult the corresponding checklist, which identified it as a No-Go item, the crew elected to troubleshoot it themselves after takeoff. Instead, they stopped on a taxiway, the SIC retrieved the pitot cover and prepared to take off again.
