Gleim Lesson 5 NG
What is the effect of advancing the throttle in flight?
Both aircraft groundspeed and angle of attack will increase.
An airplane said to be inherently stable will
Low airspeed, high power, high angle of attack.
In what flight condition are torque effects more pronounced in a single-engine airplane?
Low airspeed, high power, high angle of attack.
What causes an airplane (except a T-tail) to pitch nosedown when power is reduced and controls are not adjusted?
The downwash on the elevators from the propeller slipstream is reduced and elevator effectiveness is reduced.
What force makes an airplane turn?
The horizontal component of lift.
What determines the longitudinal stability of an airplane?
The location of the CG with respect to the center of lift.
Which basic flight maneuver increases the load factor on an airplane as compared to straight-and-level flight?
Turns.
Structural damage or failure is more likely to occur in smooth air at speeds above
VNE.
When does P-factor cause the airplane to yaw to the left?
When at high angles of attack.
Changes in the center of pressure of a wing affect the aircraft's
aerodynamic balance and controllability.
An airplane 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
difficulty in recovering from a stalled condition.
An airplane loaded with the Center of Gravity (CG) rear of the aft CG limit could
increase the likelihood of inadvertent overstress.
Loading an airplane to the most aft CG will cause the airplane to be
less stable at all speeds.
Limit load factor is the ratio of
maximum sustainable load to the gross weight of the airplane.
The left turning tendency of an airplane caused by P-factor is the result of the
propeller blade descending on the right, producing more thrust than the ascending blade on the left.
As altitude increases, the indicated airspeed at which a given airplane stalls in a particular configuration will
remain the same regardless of altitude.
The amount of excess load that can be imposed on the wing of an airplane depends upon the
speed of the airplane.
During an approach to a stall, an increased load factor will cause the aircraft to
stall at a higher airspeed.
