An inherently stable airplane is easy to fly. börja lära sig
|
|
|
|
|
It reduces pilot fatigue. börja lära sig
|
|
|
|
|
This quality is essential throughout a wide range fo flight conditions. börja lära sig
|
|
|
|
|
You will see that handling characteristics are directly related to stability. börja lära sig
|
|
|
|
|
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. börja lära sig
|
|
|
|
|
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. börja lära sig
|
|
|
|
|
Controllability is the capability of an airplane to respond to your control inputs, especially with regard to attitude and flight path. börja lära sig

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

Positive Dynamic stability It is determined by its tendency to oscillate and damp out successive oscillations. börja lära sig
|
|
|
|
|
When you consider the overall stability of an airplane. börja lära sig
|
|
|
|
|
This is accomplished during the engineering and development phase. börja lära sig

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. börja lära sig
|
|
|
|
|
The location of the center of gravity with respect to the center of lift determines the longitudinal stability of an airplane. börja lära sig
|
|
|
|
|
The nose heavy tendency is ofset by the position if the horizontal stabilizer. börja lära sig
|
|
|
|
|
börja lära sig
|
|
|
|
|
Pitching tendency occurs due to the reduction of downwash from the wings and the propeller. börja lära sig
|
|
|
|
|
The alignment of thrust in realation to the longitudinal axis. börja lära sig

A canard is a stabilizer that is located in front of the main wings. börja lära sig

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

In a light, training airplane a spin may be defined as an aggravated stall which results in autorotation. börja lära sig
