Answer |
An inherently stable airplane is easy to fly. start learning
|
|
|
|
|
It reduces pilot fatigue. start learning
|
|
|
|
|
This quality is essential throughout a wide range fo flight conditions. start learning
|
|
|
|
|
You will see that handling characteristics are directly related to stability. start learning
|
|
|
|
|
Stability is a characteristic of an airplane in flight that causes it to return to a condition of equilibrium, or steady flight, after it is disurbed. start learning
|
|
|
|
|
Maneuverability is the characteristic of an airplane that permits you to maneuver it easily and allows it to withstand the stress resulting from the maneuvers. start learning
|
|
|
|
|
Controllability is the capability of an airplane to respond to your control inputs, especially with regard to attitude and flight path. start learning

|
|
|
|
It tends to return to its original attitude after displacement. start learning
|
|
|
|
|
A tendency to move farher away from the original attitude following a disturbance is negative static stability. start learning

|
Positive Dynamic stability It is determined by its tendency to oscillate and damp out successive oscillations. start learning
|
|
|
|
|
When you consider the overall stability of an airplane. start learning
|
|
|
|
|
This is accomplished during the engineering and development phase. start learning
|
|
|
|
|
center of pressure/center of lift The center of pressure is a point along the wing chord line where lift is considered to be concentrated. For this reason, the center of pressure is often referred to as the center of lift. start learning
|
|
|
|
|
The location of the center of gravity with respect to the center of lift determines the longitudinal stability of an airplane. start learning
|
|
|
|
|
The nose heavy tendency is ofset by the position if the horizontal stabilizer. start learning
|
|
|
|
|
start learning
|
|
|
|
|
Pitching tendency occurs due to the reduction of downwash from the wings and the propeller. start learning
|
|
|
|
|
The alignment of thrust in realation to the longitudinal axis. start learning
|

|
A canard is a stabilizer that is located in front of the main wings. start learning

Dihedral is the upward angle of the airplane’s wings with respect to the horizontal. start learning
|
|
|
|
|
When you look at an airplane, dihedral makes the wings appear to form a spread out V. start learning
|
|
|
|
|
This causes an immediate side slip downward toward the low wing. start learning
|
|
|
|
|
This keel effect is the steadying influnce exerted by the side area of the fuselage and vertical stabilizer. start learning
|
|
|
|
|
The wings taper backward from the root of the wing to the wingtips. This is called sweepback. start learning
|
|
|
|
|
start learning
|
|
|
|
|
If an airplane with sweepback inadvertently rolls about its logitudinal axis and side slip occurs. start learning
|
|
|
|
|
Essentially, an airplane in flight is much like a weather vane. start learning
|
|
|
|
|
This arrangment helps keep the airplane aligned with the relative wind. start learning
|
|
|
|
|
Dutch roll is a combination of rolling/yawing oscillations caused either by control input or by wind gusts. start learning
|
|
|
|
|
start learning
|
|
|
|
|
If the Dutch roll tendecy is not effectively dampened, it is considered objectionable. start learning
|
|
|
|
|
start learning
|
|
|
|
|
The dutch roll motion is adequately suppressed. start learning
|
|
|
|
|
In a light, training airplane a spin may be defined as an aggravated stall which results in autorotation. start learning
