Roll
Roll is the up and down movement of these.
What are the wings?
Pitch moves the aircraft in this direction.
What is up and down (nose movement)?
Yaw moves the aircraft’s nose in this direction.
The aircraft rotates about this point.
What is the center of gravity?
Fixed-wing aircraft use these for roll, pitch, and yaw control.
What are control surfaces (ailerons, elevators, rudder)?
Roll is controlled by this surface.
What are the ailerons?
Pitch is controlled by this part of the aircraft.
What are the elevators?
Yaw is controlled by this surface.
What is the rudder?
The CG is the average location of this.
What is the mass of the aircraft?
Multirotors control motion by changing the speed of these.
What are motors or propellers?
When the right aileron goes up, the left one goes this direction.
What is down?
The elevators are located on this stabilizer.
What is the horizontal stabilizer?
The rudder is attached to this stabilizer.
What is the vertical stabilizer?
Proper balance around the CG is essential for this kind of flight.
What is stable flight?
Fixed-wing aircraft rely on airspeed and this to stay aloft.
What is lift from the wings?
The Wright brothers used this early technique instead of ailerons.
What is wing warping?
Both elevators move in this way.
What is together or in pairs?
Yaw control helps coordinate turns with this other motion.
DAILY DOUBLE
What is roll?
The CG can shift in an airplane as this is consumed.
What is fuel?
A quadcopter can hover in place because of this.
What is vertical thrust balance?
Modern airliners often use these devices instead of ailerons for roll control.
What are spoilers?
Pitch control changes the aircraft’s climb and this.
What is descent or dive angle?
In a quadcopter, yaw is achieved by changing the speed of these.
What are opposing motor pairs?
If weight isn’t balanced at the CG, this type of control issue can occur.
What is unwanted rotation or instability?
Understanding roll, pitch, and yaw helps pilots complete these safely.
What are UAS missions?
