lift
drag
weight
What is critical angle of attack?
That angle of attack at which a wing stalls but only at certain airspeeds or weights
That angle of attack at which a wing stalls at any airspeed, attitude or weight
That angle of attack at which a wing stalls but only a certain flight attitudes
What is used to reduce wingtip vortices
winglets
flaps
elevator
What is winglets advantage?
Reduces induced drag caused by vortices
Creates an offsetting thrust
All of the above
What is ground effect?
Increased efficiency of a wing when flying within a wing's length of the ground
An increase in drag by as much as 50% when flying within a wing's length of the ground
Condition of reduced lift when flying within a wing's length of the ground
What happens when an airplane is turned?
Loss of airspeed, unless additional power is added
Loss of altitude, unless additional lift is created
Increase in altitude, unless excess lift is reduced
What is the danger of a steeply banked turn?
Increased stall speed
Increased pitch
Decreased stall speed
What is defined as computing intermediate values between a series of given values?
Approximation
Interpolation
Estimation
What is load factor?
Ratio of the load supported by the wings as compared to the actual weight of the aircraft
Center-seeking force directed inward created by the horizontal component of lift
Amount of G's that an airplane should be capable of withstanding without failure
If a pilot has improperly loaded or balanced an airplane, during which phase of flight will poor or unsafe performance normally occur?
Takeoff
Cruise
Landing
Which of the following in NOT a primary flight control?
Elevator
Flap
Aileron
Which of the following is NOT a secondary flight control?
Rudder
Flap
Spoiler
Near stall, how should flight controls feel?
No different than at cruise speeds
Soft and sluggish
Firm and responsive
What does the checklist item "Flight Controls - FREE and CORRECT" mean?
During the outside preflight, inspect the flight control surfaces hinges for corrosion, etc.
Just before takeoff, verify that the flight controls move freely and the flight control surfaces move in the correct direction
During the outside preflight, inspect the flight control surfaces rods and pulleys
Hydraulic flight controls system
Fluids used to transmit stick forces to control surfaces
Electronic signals used to tranmit stick forces to control surfaces
Rods and pulleys used to transmit stick forces to control surfaces
Fly-by-wire flight control systems are
Rods and pulleys used to transmit stick forces to control surfaces
Fluids used to transmit stick forces to control surfaces
Electronic signals used to tranmit stick forces to control surfaces
Why are flaps, slats and slots used on aircraft?
Permit low speed characteristics for takeoff and landing
Permit high speed characteristics for cruise speeds
All of the above
In the diagram, which airplane has flaps & slats extended?
Airplane A
