Commercial Pilot Basic Aerodynamics

The L/D ratio at a 2 angke of attacj is approximately the same as the L/D ratio for a. 16.5 angle of attack. N/A. N/A.

Select the correct statement regarding stall speeds. The airplane will stall. 10 knots higher in a power-on 60 bank with gear and flaps up than with gear and flaps down. N/A. N/A.

A propeller rotating clockwise as seen from the rear, creates a spiraling slipstream. The spiraling slipstream, along with torque effect, tends to rotate the airplane to the. left around the vertical axis, and to the left around the longitudinal axis. N/A. N/A.

To avoid possible wake turbulence from a large jet aircraft that has just landed prior to your takeoff, at which point on the runway should you plan to become airborne?. Past the point where the jet touched down. N/A. N/A.

Longitudinal stability involves the motion of the airplane controlled by its. elevator. N/A. N/A.

Choose the correct statement regarding wake turbulence. The primary hazard is loss of control because of induced roll. N/A. N/A.

What is the stall speed of an airplane under a load factor of 2 Gs if the unaccelerated stall speed is 60 knots?. 84 knots. N/A. N/A.

Which is true regarding the force of lift in steady, unaccelerated flight?. There is a corresponding indicated airspeed required for every angle of attack to generate sufficient lift to maintain altitude. N/A. N/A.

An airplane leaving ground effect will. experience an increase in induced drag and require more thrust. N/A. N/A.

The angle of attack of a wing directly controls the. distribution of pressures acting on the wing. N/A. N/A.

If an airplane glides at an angle of attack of 10, how much altitude will it lose in 1 mile?. 480 feet. N/A. N/A.

The horizontal dashed line from point C to point E represents the. positive limit load factor. N/A. N/A.

Which is true regarding the use of flaps during level turns?. The raising of flaps increases the stall speed. N/A. N/A.

One of the main functions of flaps during the approach and landing is to. provide the same amount of lift at a slower airspeed. N/A. N/A.

The need to slow an aircraft below V(A) is brought about by the following weather phenomenon: Turbulence which causes an increase in stall speed. N/A. N/A.

Which is correct with respect to rate and radius of turn for an airplane flown in a coordinated turn at a constant altitude?. For a specific angle of bank and airspeed, the rate and radius of turn will not vary. N/A. N/A.

The stalling speed of an airplane is most affected by. variations in airplane loading. N/A. N/A.

If airspeed is increased during a level turn, what action would be necessary to maintain altitude? The angle of attack. must be decreased or angle of bank increased. N/A. N/A.

What is the best indicator to the pilot of the load factor on the airplane?. How firmly the pilot is pressed into the seat during a maneuver. N/A. N/A.

A rectangular wing, as compared to other wing planforms, has a tendency to stall first at the. wing root, with the stall progression toward the wing tip. N/A. N/A.
