Jeppesen Private Pilot Handbook,
Chapter 3, Section C Questions
Identify the aerodynamic force that opposes the rearward component of weight in a
climb. - answer Thrust
What relative airspeed, power, and angle of attack conditions produce the most
noticeable left-turning tendencies common to single-engine, propeller-driven aircraft? -
answer1. Low airspeed
2. High power settings
3. High angles of attack
Name three design elements that can be used to help offset left-turning tendencies. -
answerLeft turning tendencies can be corrected for, in part, through the employment an
offset vertical stabilizer and/or a rudder trim tab, and horizontally canted engines.
All else being equal, will two aerodynamically identical aircraft with different weights be
able to glide the same distance over the ground? If so, how can this be accomplished
and why? - answerYes. Variations in weight do not affect the glide ratio of an airplane,
but the heavier aircraft will sink faster, and reach the ground sooner. To travel the same
distance as the lighter aircraft, a higher airspeed will need to be maintained by the
heavier airplane. This higher airspeed, which corresponds to the best glide airspeed at
that weight, increases ground speed and allows the heavier aircraft to cover the same
horizontal distance even though its rate of descent is higher.
What causes an airplane to turn? - answerWhen an airplane is banked, lift is comprised
of two components. The airplane turns because the horizontal component of lift creates
a force directed inward toward the center of rotation.
If angle of bank and altitude are held constant, what can be done to increase the rate of
turn? - answerDecrease airspeed
Given a 1 G (maintaining level-flight) stall speed of 55 knots, use the chart provided to
determine the stall speed under the following conditions:
1. Bank angle, 30°
2. Bank angle, 45°
3. Bank angle, 75° - answer1. 59 knots
2. 66 knots
3. 110 knots
True/False. Maneuvering speed increases with a decrease in weight. - answerFalse
