Tailplane Stall; Meaning, Synonyms, Antonyms, Translation, Use Cases

Tailplane Stall

 

Have you ever had a tailplane stall scare? Of course that can be scary given the results that could be produced as an aftermath of this incident.

To help you understand tailplane stall better in this article I will tell you its meaning, synonyms, antonyms, how and when the word can be used for a better understanding.

 

Meaning

Tailplane Stall (Verb/ teɪlpleɪn stɑːl /)  is the Ice buildup on the horizontal stabilizer’s leading edge. 

 

Other Meaning

  • Tailplane stall happens When the critical angle of attack is surpassed, like with a wing.

 

  • Tailplane stall occurs when the aircraft wings experience greater air resistance and decreased lift during a stall.

 

  • The accumulation on the leading edge of the horizontal stabilizer is what is referred to tailplane lag

 

  •  In a typical wing stall, this is the loss of lift which causes the airplane to dip downward.

 

  • A tailplane stall occurs when pitching down happens, although this time due to a diminished tail-down force.

Synonyms

  • Delay in horizontal stabilization
  • Stall surface impede
  • Aerofoil arrest

      Aerofoil shelve

      Vertical tail lag

      vertical stabiliser delay

      airfoil delay

      regulating surface arrest

Antonyms

  • Uncover assist
  • natural thing
  • inside aid
  • outside assist
  • descend aid
  • disappear assist
  • Subsurface expedite

 

Translation

The origin of this term is the French verb empenner, which means “to feather an arrow.” The term “empennage” refers to the complete tail part of an aircraft.

The word can be pronounced in other world languages as:

Spanish: puesto de plano de cola

Latin: Tailplane armenti

Dutch: staartvlak kraam

Chinese: 尾翼失速 Wěiyì shīsù

Use Cases

  • The typical airflow around the tailplane will be disrupted by the buildup of ice, which will also lower the horizontal stabilizer’s critical (or stalling) negative AOA.

 

  • Depending on the configuration of the aircraft and the flap settings, increasing the power setting on a propeller-driven aircraft may result in an increase in downwash and negative tailplane AOA.

 

  • An abrupt and/or un-commanded nose-down pitching maneuver, which may be preceded or followed by a quick forward control column movement or snatch, will result from tailplane stall.

 

  • When using the autopilot, the signs of a potential tailplane stall will be concealed. In all situations, signs might not be visible until flap extension.

 

  • When a tailplane stalls, the downward thrust it generates is substantially reduced, quickly pitching the aircraft nose-down.

 

Frequently Asked Questions

How does a tailplane stall occur?

When the critical angle of attack is surpassed, like with a wing, a tailplane stall happens.

The plane will respond by tilting down when the tailplane is stalled because the horizontal stabilizer fights against the natural inclination for the nose to drop produced by the center of lift of the main wing.

 

What are the signs when entering a stall in aircraft?

The following are examples of general signs of an aerodynamic stall:

  • Activation of stall warnings that are fake.
  • Plane buffet.
  • Diminished or lost flight control authority, particularly with roll control.
  • Significant rearward movement of the control column.
  • Accelerated rate of descent
  • A tendency to pitch with the nose down when the stall happens.

 

How do you recover from a tailplane stall?

Reverse the yoke immediately if you have a tail stall. This is the reverse of the recovery from a wing stall motion that you have been taught and have practiced.

The tailplane’s angle of attack is decreased and moved away from the critical angle by pushing back on the yoke.

 

 

 Summary

Understanding what the horizontal tail of a typical airplane (i.e., one without a forward-mounted lifting surface known as a canard) performs is one of the keys to comprehending tailplane stalls and the suitable recovery technique.

As a result of the airplane’s Centre of gravity being ahead of the centre of lift, it was created to counteract the aircraft’s inclination to nose down. It accomplishes this by applying a lifting force that is opposing the wings.
