What distinguishes velocity from speed?
If an airplane flies at 260 mph southwest for 10 hours, what physical quantity does this describe?
Acceleration is defined as the rate of change of which quantity?
Which of the following best represents standard atmospheric pressure at sea level in pounds per square inch (psi)?
The angle between the chord line and the resultant relative wind is increased by which action of rotor blades?
According to Bernoulli's principle, an increase in the velocity of a fluid corresponds to what change in its pressure?
What happens to the airflow around an aircraft as its speed approaches the speed of sound?
What axis does the rudder control movement around?
Which control surface is primarily responsible for rolling an aircraft?
What force counteracts weight to keep an aircraft aloft?
Which flight control surface moves the aircraft's nose up or down around the lateral axis?
At what point does increasing angle of attack cause a stall?
True or False: Speed specifies both the rate of motion and the direction.
True or False: Positive acceleration means the velocity of an object is increasing.
True or False: The horizontal stabilizer controls the longitudinal stability of the aircraft.
True or False: The rudder moves the aircraft around the longitudinal axis.
True or False: Bernoulli's principle connects fluid velocity and pressure.
True or False: Static stability means an aircraft will never return to equilibrium after disturbance.
True or False: Fowler flaps increase both wing area and camber for better lift.
True or False: An aircraft experiences no acceleration when in equilibrium.
True or False: Drag is the force that helps an aircraft move forward.
True or False: Slats help delay airflow separation at high angles of attack.
True or False: A stabilator combines the functions of the horizontal stabilizer and elevator.
True or False: The force of thrust opposes the force of drag.
What is the effect of increasing angle of attack on lift until the critical angle is reached?
Which component of an aircraft primarily affects its yaw motion?
True or False: Increasing thrust always increases an aircraft's speed.
True or False: The elevator controls the roll of the aircraft.
What is the relationship between velocity and acceleration?
True or False: An aircraft can maintain a constant speed while experiencing negative acceleration.
What happens to pressure when fluid velocity increases?
True or False: The concept of diameter is integral to understanding airflow around the wing of an aircraft.
Which of the following best describes the role of slats on aircraft wings?
What is the primary factor affecting lift produced by an aircraft wing at different angles of attack?
True or False: An increase in angle of attack always results in increased lift until the stall point is reached.
True or False: The thrust produced by an aircraft is primarily responsible for overcoming the force of drag during flight.
