Gust

Aviation  Gull-wing  Gust lock

gust conditions
A gust or bump increases the load on the wings. The speed of the airplane should therefore be reduced when flying in gusty air.


Gust. A sudden local fluctuation in velocity of the wind.
Gyroplane. A mechanically-driven aeroplane deriving its lift from the reaction of the air on one or more rotors freely rotating in a horizontal plane.

Log gust spreads and sock activity
While practicing crosswinds, keep a mental record of the gust spreads and how they made the sock behave to develop an understanding of what the sock is actually telling you.

Remove the gust lock and tail tiedown if any. Take a good look at the underside of the stabilizer and elevator. Make sure to inspect the hinges for any extra movement or unusual play.

If the air current is well defined and travels at a significant rate of speed upward (15 to 30 feet per second), a sharp vertical gust is produced which will have the same effect on the wing as applying sudden sharp back pressure on the elevator ...

This means that if a gust during the “skimming” phase (after the roundout) causes you to touch down a little sooner than you intended, you will still touch down on the main wheels.

Will a kite return to a designed or desired flight mode or position after being disturbed by a gust or kite operator control action? How large of a gust can be tolerated?

Just after touchdown, a gust of wind lifted the left wing and the right wing struck the water. The airplane nosed over abruptly, and the cabin immediately filled with cold lake water.

When an aircraft is given a symmetric disturbance as may be caused by a sudden up-gust or step elevator movement, the incidence of the aircraft will change and the aircraft will begin to pitch. The resulting motion consists of two modes.

Le Bris was hoping for a gust which should enable him to rise; he thought it had come, pulled on his levers, and thus threw his wings to the most favourable angle, but he only ascended a dozen yards, glided scarcely twice that distance, ...

Suppose that the airplane balancing at an angle of 2degrees so that the center gravity coincides with the center of lift for this angle; now if a gust of wind causes the angle increase for an instant to 2 degrees, ...

Take the gust "factor" and add it to your approach speed. If, for example, the wind is at 20 knots with gusts to 30 knots, add the gust factor of 10 knots to your normal approach speed of 100 knots for a final speed of 110 knots.

The tail fin determines the directional stability.
If a gust of wind strikes the aircraft from the right it will be in a slip and the fin
will get an angle of attack causing the aircraft to yaw until the slip is eliminated.

This can be detected by installing the control wheel gust lock and then attempting to move the elevator's trailing edge — if it moves more than an inch or two, inspect the bracket, which is below the floor under the front seats.

For instance, if an aircraft is traveling north, and a gust of wind comes from the northwest side of the aircraft, the pilot will need to steer the airplane a little towards the northwest in order to maintain his straight northerly course.

TURBULENCE MODE
Flight control system mode in which a "softer" response to gust upsets is programmed.
TVOR
very high frequency terminal omni range station.

If a disturbance occurs (a gust or a short push or pull on the control), the aircraft is said to be stable if it returns to its original speed (this is associated to the aircraft's nose position with respect to the horizon).

TDWR- Terminal Doppler Weather Radar. TDWR provides information on windshear, microburst, and gust front activity in the vicinity of the airport.

VB Design speed for maximum gust intensity.
VC Design cruising speed.
VD Design diving speed.
