A pilot can induce a flat spin once the spin is established by applying full opposite aileron to the direction of rotation—hence, the requirement to neutralize ailerons in the normal spin recovery technique. The aileron application creates a differential induced drag that raises the nose toward a level pitch attitude.
Spin Erect spin; Inverted spin; Flat spin: A family of auto-rotational maneuvers, consisting of normal or "flat" spins, either upright or inverted. Two components must exist to spin an aircraft: 1) critical angle of attack (COA), which means that the aircraft is stalled, and 2) yaw. Tailslide Bell Tailslide
The inner ear contains the vestibular system, which is also known as the organ of equilibrium.About the size of a pencil eraser, the vestibular system contains two distinct structures: the semicircular canals, which detect changes in angular acceleration, and the otolith organs (the utricle and the saccule), which detect changes in linear acceleration and gravity.
Conversely any decrease in angle of attack causes a decrease in lift coefficient which causes the wing to descend. As the wing descends, the angle of attack and lift coefficient increase which tends to restore the wing to its original angle of attack. For this reason the angle of attack is stable when it is less than the stalling angle.
The only dangerous aspect of a stall is a lack of altitude for recovery. Incipient spin & recovery. A special form of asymmetric stall in which the aircraft also rotates about its yaw axis is called a spin. A spin can occur if an aircraft is stalled and there is an asymmetric yawing moment applied to it. [17]
SAO PAULO (Reuters) -A regional turboprop plane fell into what aviation experts called a flat spin before crashing in a residential neighborhood near Sao Paulo in Brazil on Friday, killing all 61 ...
The pilot who died in a small plane crash Sept. 23 was performing an inverted flat spin before his plane crashed into the Cumberland River in Cheatham County, according to the National Safety and ...
An aircraft with a T-tail may be easier to recover from a spin, as the elevator is not in a position to block airflow over the rudder, which would make it ineffective, as can happen if the horizontal tail is directly below the fin and rudder. [2] The T-tail increases the effectiveness of the vertical tail because of "end plate" effect.
