Ground school- basic aerodynamics

The term “angle of attack” is defined as the angle

• Between the wing chord line in the relative wind

• Between the airplanes, climb angle, and the horizon

• Formed by the longitudinal axis of the airplane and the chord line of the wing

Wingtip vortices, created by large aircraft tend to

• Sink below the aircraft generating turbulence

• Rise into the traffic pattern

• Rise into the takeoff, or landing path of a crossing runway

If an airplane weighs 2300 pounds, what approximate weight would the airplane structure be required to support during a 60° banked turn while maintaining altitude

• 2300 pounds

• 3400 pounds

• 4600 pounds

While practicing S turns, a consistently smaller, half circle is made on one side of the road than the other, and this turn is not completed before crossing the road or reference line. This would most likely occur in turn.

• 1-2-3 because the bank is decreased to rapidly during the later part of the turn

• 4-5-6 because the bank is increased to rapidly during the early part of the turn

• 4-5-6 because the bank is increased, too slowly during the later part of the turn

Which statement relates to Bernoulli’s principal

• For every action, there is an equal and opposite reaction

• An additional upward force is generated as the lower surface of the airfoil deflects air downward

• Air traveling faster over the curved upper surface of an airfoil causes lower pressure on the top surface

What is one purpose of wingflaps

• To enable the pilot to make steeper approaches to a landing, without increasing the airspeed

• To relieve the pilot of maintaining continuous pressure on the controls

• To decrease wing area to vary the lift

During an approach to a stall, an increased load factor will cause the airplane to

• Stall at a higher airspeed

• Have a tendency to spin

• Be more difficult to control

Loading an airplane to the most aft CG will cause the airplane to be

• Less stable at all speeds

• Less stable at slow speeds, but more stable at high speeds

• Less stable at high speeds, but more stable at low speeds

The wind condition that requires maximum caution when avoiding wake turbulence on the landing, is a

• Light, quartering headwind

• Light, quartering tailwind

• strong headwind

An airplane that has been loaded in such a manner that the CG is located aft of the aft CG limit. One undesirable flight characteristic a pilot might experience with this airplane would be.

• A longer take off run

• Difficulty in recovering from a stalled condition

• Stalling at higher than normal air speed
