Category 1: Axes, Forces & Motion
This axis runs wingtip to wingtip and controls pitch.
What is the lateral axis?
Stability around the lateral axis is called this.
What is longitudinal stability?
A stall occurs when this exceeds its critical value.
What is angle of attack?
This effect increases lift and reduces drag when flying close to the ground.
What is ground effect?
This system mixes fuel and air before entering the engine.
What is the fuel induction system?
Rotation about this axis is called yaw.
What is the vertical axis?
This type of stability refers to the aircraft’s initial tendency to return to equilibrium.
What is static stability?
Increasing load factor causes stall speed to do this.
What is increase?
Wingtip vortices are strongest under this flight condition.
What is high lift at low speed (takeoff/landing)?
This device vaporizes fuel using a venturi effect.
What is a carburetor?
This axis runs nose to tail and controls roll.
What is the longitudinal axis?
Stability around the vertical axis.
What is directional stability?
A spin is a stalled condition combined with this type of motion.
What is autorotation?
This type of drag is caused by lift production.
What is induced drag?
This hazard occurs when moisture freezes in the carburetor throat.
What is carburetor icing?
The total aerodynamic force perpendicular to the relative wind.
What is lift?
The control surface primarily responsible for pitch.
What is the elevator?
This type of stall occurs when one wing stalls before the other.
What is an asymmetric stall?
Wake turbulence is primarily caused by these rotating air masses.
What are vortices?
Fuel-injected engines reduce the risk of this compared to carbureted engines.
What is carburetor icing?
The ratio of total lift to the aircraft’s weight.
What is load factor?
This stability describes long-term oscillations after a disturbance.
What is dynamic stability?
In a coordinated level turn, load factor increases due to this tilted force.
What is lift?
Downwash alters the effective angle of attack in this direction.
What is downward?
This control adjusts the fuel-air mixture for altitude.
What is the mixture control?
