LOFT Saturday Fly for Fun Sessions
Offer coaching to less experienced flyers
Refine sailplane set ups
Learn to fly from high-starts or a winch
Encourage non-members to join the Club.
Fly for Fun (Fly what you Bring)
Set up would be done by whomever gets there first. Wind direction will dictate set up location on the field. Frequency control will be in place using a portable frequency board. Signage would be placed at key locations around the field. All sessions will start with a brief meeting and pilots sign in sheet with flying beginning at 9:30 and end around noon unless other activities are planned for that day.
High Starts – bring your own plus any Club High Starts
Winches – one will be used initially until we determine need.
Club Plane and radio – will be available to all members and non-members.
Signs – these signs would be put up at the field to attract attention to the activity. One sign will be the normal LOFT sign; the other sign will be for the Fly for Fun session including an invitation for the public to join us.
Portable Field pack – it will contain the frequency control board, clothes pins, sign-up sheets, pens, LOFT Tri-folds, etc.
All sessions will start at 9:30 am and end around noon unless we want to fly more.
Thermal: Small rising column of air due to surface heating.
Wind: Air moving (sometimes with considerable force) from an area of high pressure to an area of low pressure.
High Pressure: A mass of air that presses down strongly on the surface of the Earth because it is being cooled and is therefore more dense
Low Pressure: A system in which air pressure decreases toward the center, associated with unsettled weather, usually formed by a mass of warm air being forced up by cold air.
Wind Shear: Any sudden change in wind speed or direction.
Updrafts: The upward movement of warm air. Updrafts can be found beneath and inside all types of cumulus clouds.
Downdrafts: A small-scale column of air that rapidly sinks toward the ground, usually accompanied by precipitation as in a shower or thunderstorm. A downburst is the result of a strong downdraft.
Cloudburst: A strong downdraft of air from a cumulonimbus cloud, of limited duration and often associated with intense thunderstorms.
Convection currents: The currents caused by hot air rising and falling. Hot air expands and is therefore less dense than its cooler surroundings, thus it rises; as it cools it contracts, becomes more dense and sinks down creating a rolling motion.
Dust Devil: A small atmospheric vortex not associated with a thunderstorm, which is made visible by a rotating cloud of dust or debris Dust devils form in response to surface heating during fair, hot weather.
Orographic Lift – Lifting of air caused by its passage up and over mountains or other sloping terrain.
Ridge – An elongated area of relatively high atmospheric pressure
Squall Line – A solid or nearly solid line or band of active thunderstorms.
Virga – Streaks or wisps of precipitation falling from a cloud but evaporating before reaching the ground.
Wave – In meteorology, the intersection of warm and cold fronts.
