Spins Flashcards
(22 cards)
What is a spin in aviation?
An aggravated stall resulting in autorotation, where the airplane follows a corkscrew path downward.
What happens if the nose of the airplane is allowed to yaw at the beginning of a stall?
The wing drops in the direction of the yaw.
What causes an airplane to slip toward the lowered wing during a stall?
Lack of rudder application to keep the nose from yawing.
What is the effect of the relative wind on the lowered wing during a stall?
It has an increasingly greater angle of attack (AOA), leading to loss of lift and increased drag.
What happens to the rising wing during a stall?
It develops some lift as it has a smaller angle of attack than the lowered wing.
What is required for an airplane to spin?
Both wings must be stalled, then one wing becomes less stalled than the other.
What characterizes a flat spin?
The spin axis is located near the airplane’s center of gravity (CG).
What makes recovery from spins and stalls difficult?
When the center of gravity (CG) is too far rearward.
What is the rotation of a spin always around?
The center of gravity (CG).
What is an over-the-top spin?
A slipping turn stall, often occurring in the traffic pattern.
What should a pilot do to properly compensate for overshooting the runway centerline?
Increase the rate of turn while maintaining a coordinated turn.
What happens if a pilot holds the bank constant during a turn?
The airplane may begin an uncommanded roll toward the inside wing.
What are the four phases of a spin?
- Entry phase
- Incipient phase
- Developed phase
- Recovery phase
What is the entry phase of a spin?
When the pilot provides the necessary elements for the spin, either accidentally or intentionally.
What should be done during the developed phase of a spin?
The spin is stabilized with a nearly vertical flight path and aerodynamic forces are in balance.
What is the suggested technique for spin recovery?
- Neutralize the ailerons
- Close the throttle
- Apply opposite rudder
- Apply positive forward elevator movement
- Neutralize the rudder as the spin stops
- Return to level flight
What should be avoided during spin recovery?
Excessive elevator back pressure, which could result in a secondary stall.
What is prohibited regarding intentional spinning of an airplane?
It is prohibited and extremely dangerous for airplanes not specifically approved for spins.
What must an airplane be certified for spins in the normal and utility categories?
It must be recoverable from an incipient spin, not a fully developed spin.
What should a pilot assume about an airplane placarded against spins?
That the airplane may become uncontrollable in a spin.
How can continued practice in stalls help a pilot?
It helps develop a more instinctive and prompt reaction in recognizing an approaching spin.
Fill in the blank: The recovery phase begins when controls are applied to stop the spin and ends when _______.
[level flight is attained]
