Fence

03/09 - Don't Fear the Imaginary Fence
By Steve Krog
Almost from the time he was born, Romy Baus, a 52-year-young design engineer, has had the urge to go fast and do things others haven't done.

wing fences
Wing fences are fin-like vertical surfaces attached to the upper surface of the wing, that are used to control the airflow.

Blast Fence: A barrier used to divert or dissipate jet blast or propeller wash.

BLAST FENCE- A barrier that is used to divert or dissipate jet or propeller blast.

A wingtip fence is a winglet variant, with surfaces extending both above and below the wingtip. Both surfaces are shorter than or equivalent to a winglet possessing similar aerodynamic benefits.

An airport fence need not be a barrier. Student pilots are welcomed into the rewarding world of general aviation flying.
With the help of an instructor, student pilots quickly learn the basics of regulations and aerodynamics.

* Winglets, Fences, “Lateral” Flow, etc.
It is a common misconception that the wingtip vortices are somehow associated with unnecessary spanwise flow (sometimes called “lateral” flow), ...

ADIZ - Air Defence Identification Zone. An area of airspace extending upwards from the surface, usually along a national boundary, within which identification of all aircraft is required in the interests of national security.

IADS - Integrated Air Defence System - an air defence system where many different systems are integrated so that commanders may get a 'big picture' and information verification.

After a short distance aloft, perhaps 50 yards, he crashed on top of his own gorse fence. No details were recorded, by Pearse or onlookers, of this tentative flight.

There was, as yet, no effective defence against air attacks. Having achieved command of the air, pilots would then destroy the enemy's will to resist by conducting aerial bombing on his cities, industrial centres and civilian population.

VORTILONS - Small fencelike surfaces extending in front of the wing and attached to the undersurface. They are particularly useful in preventing spanwise flow at high angles of attack, by shedding a vortex, similar to that of a wing fence.

The visibility had to be 100 miles and check points were lined up out front like fence posts. A real no-brainer cross country.

GPS (Global Positioning System) Satellite-based navigation system operated by Department of Defence, providing extremely accurate position, time, and speed information to civilian and military users. Based on a "constellation" of 24 satellites.

Some aircraft have a stall fence on top of the wing, others employ a discontinuous leading edge (Kodiak from Quest Aircraft) creating a vortex over the wing at high angles of attack.

Using 85 knots around the pattern and as little as 75 knots across the fence (roughly the same numbers you'd use in the old Columbias), the Evolution can easily handle 2,000-foot strips.

AWACS - Airborne warning and control system; an advanced AEW aircraft, with additional facilities for deployment and control of defence, interception, and counter-strike forces.

or so, a field of this length is of course not big enough for frequent use, especially if bordered by trees, telegraph lines, fences, and so forth. A field for temporary use should be at least 200 by 200 yd., about 9 acres.

maintain control of the aircraft in spite of the fact that he would like to land as slow as possible to minimize the contact energy and reduce the ground run distance for a decent landing on an unknown spot which may have hidden ditches or a fence ...
