INSTI R1 - FINAL QUIZ

In steady, level, unaccelerated flight, what is the relationship between the four fundamental forces?

• Lift > Weight and Thrust > Drag

• Lift = Weight and Thrust = Drag

• Lift < Weight and Thrust < Drag

• Lift = Drag and Thrust = Weight

What is considered the pilot's primary tool for controlling the aircraft's lift?

• Speed

• Angle of Attack (Wing Tilt)

• Air Density

• Wing Size

What is the main purpose of deploying flaps on the trailing edge of a wing?

• To decrease drag during high-speed cruise

• To increase the wing's curvature (camber) and lift for slower speeds

• To control the roll of the aircraft

• To act as the primary means of braking

Which type of drag is a direct byproduct of generating lift and decreases as airspeed increases?

• Parasite Drag

• Form Drag

• Induced Drag

• Skin Friction Drag

The upward angle of the wings, known as dihedral, is a design feature that primarily contributes to which type of stability?

• Longitudinal Stability (Pitch)

• Lateral Stability (Roll)

• Directional Stability (Yaw)

• Dynamic Stability

Which layer of the atmosphere contains all weather and the jet stream?

• Stratosphere

• Mesosphere

• Thermosphere

• Troposphere

Movement of the aircraft around its longitudinal (nose-to-tail) axis is called what?

• Pitch

• Roll

• Yaw

• Sway

Which aircraft component controls pitch by moving on the horizontal stabilizer?

• Rudder

• Aileron

• Elevator

• Flap

The "weathervane" effect of the vertical stabilizer helps maintain which type of stability?

• Longitudinal

• Lateral

• Directional

• Static

Which control surfaces are used to control roll?

• Elevator

• Rudder

• Flaps

• Ailerons
