unobstructed. Remember you will cover far more ground if you fly down wind.
 
−
 
 
−
2. By 1500 FT. Pick an area with 2 or 3 potentially suitable fields: consider the surrounding
 
−
terrain.
 
−
 
 
−
a. Are there hills to create turbulence or surface wind problems?
 
−
 
 
−
b. Are there TV cables, TV masts or other large obstacles?
 
−
 
 
−
c. Does the ground slope visibly? If so is it to steep?
 
−
 
 
−
d. Stay orientated with wind direction experienced during the cross-country – relate to
 
−
sun position.
 
−
 
 
−
3. By 1000 FT. Select your field considering the following:
 
−
 
 
−
a. Surface Wind – assess the wind by means of your drift or by smoke. Always aim to
 
−
land in a direction, which will give you a substantial headwind component.
 
−
 
 
−
b. Field Length – remember the apparent size of any field is seen relative to the size of
 
−
those surrounding it. Know the topography of the country over which you are flying. A
 
−
good field for a modern glider would be 500 – 600 yards long with relatively
 
−
unobstructed boundaries.
 
−
 
 
−
c. Obstructions – obstructions reduce the useable field length by at least 10 times the
 
−
height at which you clear them. Trees and buildings will also create turbulence.
 
−
d. Slope – any visible down slope in the field is unacceptable. A similar upslope would be
 
−
acceptable (the wheel brake will be needed). Examine surrounding fields for slope
 
−
indications. Fields at the bottom of a valley often suffer from excessive slope.
 
−
 
 
−
e. Surface – look for fields in the following order of priority:
 
−
 
 
−
(1) Stubble
 
−
 
 
−
(2) Grass – but beware of strip grazing indicating electric fences – any shading in
 
−
the grass surface almost certainly indicates the presence of fencing.
 
−
 
 
−
(3) Short Crop – the surface should appear more brown than green.
 
−
 
 
−
(4) Other cropped fields may present a hazard on landing – remember half-ripe
 
−
crops may look like stubble – consider the season!
 
−
 
 
−
f. Stock – Sheep panic, run and sometimes jump up. Cows are curios, horses bolt. A
 
−
solitary cow is probably a bull! Try to avoid fields with stock in them.
 
−
 
 
−
4. By 800 ft AGL – Position the glider well upwind and well to one side of your field – visualise
 
−
the length of the downwind leg at your home airfield. Use pre-selected ground reference
 
−
points to maintain orientation and positioning. Be conscious of the tendency to cramp your
 
−
circuit and plan to avoid doing so.
 
−
 
 
−
5. Base Leg Position – Plan to be abeam your touchdown by 400 to 500 ft. resist the common
 
−
tendency to position the base leg to close – plan for a half airbrake approach. Select a safe
 
−
approach speed. Excessive speed will usually result in overshooting the field. Allow an
 
−
adequate margin of height over obstructions. Once you are certain you can safely clear them
 
−
use full airbrake to achieve an early touch down. Aim for minimum touch down speed on
 
−
rough surfaces. Ground looping is common when landing in crop. Concentrate on keeping
 
−
the wings level and retract flaps if necessary.
 
−
In addition to the mandatory Bronze badge field landing requirement, the BGA recommends periodic
 
−
field landing refresher training in an SLMG.

==Guidance for Pilots Following a Field Landing==
 
−
 
 
−
Glider pilots almost always set off on a flight that will result in a landing back at the base airfield.
 
−
Occasionally a flight does not quite go to plan and can result in a field landing. So glider pilots need
 
−
the co-operation of farmers and landowners. Their assistance and goodwill is imperative for the
 
−
future of our sport. What follows is set of guidelines, based on a document produced by Lasham, to
 
−
assist glider pilots in their interaction with farmers and landowners after a field landing. Field selection
 
−
and how to land in a field are separate topics not covered by this document.
 
−
 
 
−
 
 
−
'''Trespass'''
 
−
By landing in a field without first gaining the landowners permission, a pilot is committing an
 
−
actionable civil wrong. In the eyes of the law the pilot is trespassing. With this in mind, it is clearly
 
−
appropriate to be humble, polite and apologetic having landed uninvited on someone’s land. Think
 
−
about how you would feel if someone appeared uninvited in your back garden.
 
−
 
 
−
 
 
−
'''Meeting the Farmer'''
 
−
Of course you must find the farmer or a representative of the farmer – its time well spent while
 
−
waiting for your crew. First impressions count and your being there is going to cost the farmer time if
 
−
nothing else. Farmers are very busy people. Bear this in mind when introducing your self. Stress that
 
−
your landing in his field was not planned. Explain what you were trying to do. Let the farmer know
 
−
that you will try to ensure you will be as little trouble to him as possible and that with his permission
 
−
you can remove your aircraft with the minimum of fuss and trouble.
 
−
 
 
−
 
 
−
'''Retrieve'''
 
−
Almost always when landing in a field, a road retrieve is the only or best option. Aerotow retrieves
 
−
should be approached with great caution. If an aerotow retrieve is appropriate, ask the farmers
 
−
permission and explain what will happen. Understandably, most farmers will have no prior experience
 
−
of an aircraft taking off from their land, let alone two aircraft joined by a rope. So take time to explain
 
−
it clearly.
 
−
 
 
−
 
 
−
'''Damage to the Field or other Property'''
 
−
If damage has been caused to crop etc, your glider third party insurance will cover any related costs.
 
−
Do not offer to pay compensation there and then and do not admit any liability. The landowner or
 
−
farmer may quickly estimate the value of any damage and demand that you pay up. Accurately
 
−
valuing crop or other damage is a job for a professional assessor and your insurance company will
 
−
make the arrangements. Exchange addresses and insurance company names with the landowner,
 
−
and contact your insurance company as soon as possible. The insurer will assess the damage and if
 
−
appropriate, will reimburse the farmer. If possible, take photo's of any damage as this may help in the
 
−
event of a dispute.
 
−
 
 
−
 
 
−
'''Landing Fee…'''
 
−
Farmers have been known to request a landing fee for both balloons and gliders. Balloons are mostly
 
−
commercial ventures and may have up to 20 people on board all paying their way. The farmer quite
 
−
understandably expects a slice of the action. Gliders are different – we aim to get back to our base
 
−
airfield and are not commercially operated. If the farmer wants a landing fee from you;
 
−
 
 
−
- Do not dismiss him out-of-hand
 
−
 
 
−
- Ask why he thinks it is necessary
 
−
 
 
−
 
 
−
'''BGA Guidance Post Field Landing'''
 
−
 
 
−
If you have not damaged anything, and do not require his services to drag the glider out or to prevent
 
−
sightseers wandering onto his property, no landing fee should be paid. Several years ago the BGA
 
−
and the National Farmers Union agreed a code of conduct for glider pilots landing in fields (the code
 
−
is described in BGA Laws and Rules). At that time a maximum landing fee for gliders of £3.50 was
 
−
agreed. As peoples expectations and farming overheads move on over time, consider offering an
 
−
absolute maximum of £20 as a goodwill gesture for the farmers trouble and hospitality. It’s worth
 
−
noting that the balloonists (mainly commercial, remember) recommend a maximum of £80 paid when
 
−
a large passenger carrying balloon lands in a farmers field.
 
−
 
 
−
If your farmer doesn’t accept your offer and demands more, refuse politely and refer him to his local
 
−
NFU representative. You will not know who that is, but he most certainly will.
 
−
 
 
−
And in the unlikely event of the situation getting difficult…
 
−
 
 
−
Legally, you cannot be prevented from leaving a property or from taking your glider with you. You
 
−
may be expelled by force, but no more than is reasonably necessary and not before you are asked to
 
−
leave. Your aircraft may not be confiscated or impounded – that is a form of theft. If you have been
 
−
prevented from reasonably retrieving your aircraft, the person preventing you has effectively taken
 
−
charge of the safe keeping of that glider. Politely explain this to that person and point out to him or
 
−
her the value of the equipment that he or she has just impounded.
 
−
 
 
−
If anyone threatens you or if you feel threatened, call the police. They will not wish to get involved in
 
−
a case of trespass as this is a civil offence. But in cases where you have been personally threatened,
 
−
a criminal offence may have taken place and the police will get involved.
 
−
 
 
−
 
 
−
'''Finally'''
 
−
Regardless of your reception, be polite and stay calm. Always leave the farm knowing that you could
 
−
land back there again tomorrow. Always consider following up your experience with a thank you.
