Aerial cloud seeding

Cloud seeding, a form of intentional weather modification, is the attempt to change the amount
or type of precipitation that falls from clouds, by dispersing substances into the air that serve
as cloud condensation or ice nuclei, which alter the microphysical processes within the cloud.
The usual intent is to increase precipitation (rain or snow), but hail and fog suppression are also
widely practiced in airports.

The most common chemicals used for cloud seeding include silver iodide and dry ice
(solid carbon dioxide). Liquid propane, which expands into a gas, has also been used.
This can produce ice crystals at higher temperatures than silver iodide. The use of hygroscopic
materials, such as salt, is becoming more popular after promising research.

Seeding of clouds requires that they contain supercooled liquid water—that is, liquid water colder
than zero degrees Celsius. Introduction of a substance such as silver iodide, which has a
crystalline structure similar to that of ice, will induce freezing nucleation. Dry ice or propane
expansion cools the air to such an extent that ice crystals can nucleate spontaneously from
the vapor phase.
Unlike seeding with silver iodide, this spontaneous nucleation does not require any existing
droplets or particles because it produces extremely high vapor supersaturations near the
seeding substance.However, the existing droplets are needed for the ice crystals to grow
into large enough particles to precipitate out.

In mid-latitude clouds, the usual seeding strategy has been based on the fact that the
equilibrium
vapor pressure is lower over ice than over water. The formation of ice particles in supercooled
clouds allows those particles to grow at the expense of liquid droplets. If sufficient growth takes
place, the particles become heavy enough to fall as precipitation from clouds that otherwise
would produce no precipitation. This process is known as "static" seeding.

Nose wheel steering trouble

Maintenance

One of the questions most asked from light Cessna Pilots and Mechanics, is how
to correct nose wheel shake or shimmy. The Cessna factory also receives
numerous inquiries on this subject and has issued SE84-21 Service Information
Letter to provide some guidelines for troubleshooting shimmy problems in the field.
The following is a compilation of what Cessna suggest are the usual causes of,
and solutions for, nose wheel shimmy.

Nose Wheel Tire & Wheel Assembly Balance

Balancing the nose wheel/tire assembly is the most important point to check in
trying to solve a shimmy problem. Aircraft tire and tube manufacturers paint a red
dot on the tire for the “light” spot. A yellow stripe on the tube, or the valve stem
should be aligned with the red dot for coarse balance during tire buildup. Then
the tire/wheel assembly is balanced with a static type (bubble) balancer
