Common questions about hang
gliding
|
 |
|
Most people ask the same questions when they
are thinking about taking up hang gliding. What
happens when the wind stops, etc...
Here are the answers to those
questions.
|
|
What
is a hand glider?
There's no such thing. It's a HANG GLIDER.
So called because the pilot hangs underneath the wing.
How
do you learn, do you just jump off a cliff?
No, you don't just jump off a cliff.
You would die a fairly spectacular death if you did that.
You should find a hang gliding school in your area and book
onto a course. In the UK it takes roughly 10 days to complete
your training to basic level where you are then free to join
a local club and use their sites. The first 5 days are spent
on a very slow and basic training glider. You will learn how
to rig and de-rig the glider, launch and land the glider and
then progress from flying low skims to higher flights involving
gentle 30 degree turns. Your second 5 day course will see
you moving onto a slightly higher perfomance wing and higher
flights. Your turns will be increased to the point where you
are able to do 180 degree controlled turns and land in a defined
area. You will also have to pass an exam on basic Airlaw,
Flight Theory, Navigation and Meteorology.
I should say that the chances of getting 5-10
days of good weather in the UK are probably zero. The reality
is that it will take you an average of six months to get qualified
in the UK due to bad weather. I write more about this here.
If you really want to learn to fly quickly,
go Wallaby Ranch in
Florida and forget trying to learn in the UK.
For a short introduction
to hang gliding and what might happen on
your first day as a student in the UK...go here
Can you fly in any weather, in the rain for instance?
You can't just go and fly in any weather. Hang
gliding is a weather dependant sport and the ideal conditions
for flying are fine weather with light to moderate winds,
up to 20 mph (32 kph), and no rain. Rain only makes the glider
wet and hard to handle. It makes it stall more easily and
it's miserable to fly in. You have to get used to the idea
that you can only fly when the weather allows. This is the
most frustrating part of this sport, especially if you live
in the UK where the weather changes constantly.
You can fly in snow though as long as it's not
sleet. Dry snow doesn't stick to the wing and so doesn't cause
any handling problems. I wouldn't recommend flying in a blizzard
though, you have to be able to see what you are doing. Light
snow is fine and flying over a snowy landscape is very nice,
but cold, especially on your nose.
|
Do
you fall off when your arms get tired?
No. The reason for this is that you are
suspended in the glider by a harness which is zipped
up in flight and you only use your arms to hold the
control bar. You can and should fly with a light touch,
much like driving a car.
You can see that the pilot on the right
is neatly zipped into his harness. The parachute is
visible, attached to the right side of the harness.
|
 |
How
do you steer it?
The glider is controlled by the pilot who steers
the glider by shifting his weight either left or right, back
or forward, or a combination of these. He does this by holding
what is known as the A Frame or Control Frame. Moving your
centre of gravity to the left will induce a left turn in the
glider. Similarly, moving to the right will produce a right
turn. To slow the glider down the pilot moves his weight backwards
and to increase speed, he moves his weight forward. This is
all done with subtle movements of the A-frame.
|
How
do you stop the thing?
You actually land the glider by performing
a "flare". The action of pushing the A frame forward
and upwards away from you and shifting your weight backwards
causes the glider to stall in a controlled manner and
you land neatly on your feet. This technique is an art
in itself and takes a fair bit of practice to acheive
good results, especially on higher performance gliders.
The flare is only performed at the final phase of the
landing just as the glider is running out of airspeed
and when the pilots feet are just a few inches from
the ground.
|
 |
| The pilot
performs a 'flare' and brings the glider to a stop
which lands the pilot neatly on his feet. |
|
How
long can you stay up for?
Well that depends on a few things. Hang gliders
don't have an engine to drive them through the air so the
pilot has to rely on rising air to keep them up or to gain
height. If the conditions are right the skilled pilot may
stay in the air for many hours.
A hang glider has a 'sink rate' of around 180
ft per minute. If the air that the glider is flying in is
rising faster than the sink rate of the glider then the net
result is a gain in height.
An easy way to think of this is to imagine that
you are a kid who decides to walk down the up escalator in
a department store. We've all seen kids do this and you have
probably done it yourself at some point. The escalator is
coming up slightly faster than you can walk down it so what
happens is that you don't quite get to the bottom. the same
thing happens to a glider in rising air. If the air rises
faster than you are sinking through it, then you go up.
note: There is
actually a powered HG option but that takes you away from
the pure free-flight ideals of hang gliding. It is still hang
gliding but with the addition of a powered
harness
Where
can I find some rising air?
The most common sources are what we glider pilots
call 'thermals' and ridge lift.
|
Thermals:
a thermal is simply a collumn of air that rises
because it is warmer than the surrounding air. Common
thermal sources are ploughed fields, large tarmac surfaces
etc. These surfaces are darker coloured and heat up
easily in the sun. The air above these places is heated
and eventually starts to rise forming a thermal which
we can use to gain height.
Thermals can rise thousands of feet and
pilots use them to acheive cross country flight. As
they get to the top of a thermal they use the height
to glide towards the next likely thermal source and
thus acheive great distances across country.

|
| Ridge lift:
is simply air that is forced to rise up over a hill or
a cliff. To have ridge lift you need to have wind that
is blowing on to the face of the hill. Because the hill
presents an immoveable object, the wind is forced to travel
up and over the hill and therefore creates a band of rising
air in front of the hill or ridge. This is what glider
pilots use to stay up. Pilots will usually use ridge lift
while waiting for a thermal to come through to get them
really high. |
 |
|
This is my artists impression
of Ridge Lift as the air is forced upwards when
it meets the face of the hill
|
|
|
How
high can you get?
It depends on the conditions that you fly in but in
hot dry areas like Australia, America or central Spain,
flights of around 16,000 ft are possible. Pilots usually
use oxygen when flying much higher than 10,000 ft as
hypoxia can be a problem above this height.
The photo on the right was taken from
the glider at around 7,000 ft in the French Alps
|
 |
Most flights that involve cross country flying
in Britain are done at around an average of 3,000 - 5,000
ft. Our airmass is generally too damp to get really high cloudbases
but occasionally on a really good day you can get higher than
that.
How
far can you fly?

The (official) world record stands
at 435.4 miles. (700.6 k) That was set in Zapata, Texas,
by Manfred Ruhmer on a Laminar on 17/07/2001

however...
On Thursday 20th June 2002, Mike Barber flew
further than anyone else on a Hang Glider, with a total
distance of 437 miles (703kms). Mike flew the
distance on a Moyes
Litespeed 4, in Texas. For some strange reason it
has not been ratified as a new record. It is however
the longest flight ever made by any man on a hang glider.
Well done Mike Barber!

These records will probably have been broken by now, I don't
know.
What
happens when the wind stops?
It's funny how people ask that. The thing is
that the wind never really just stops. Have you ever been
out on a windy day and the wind suddenly just stopped? No,
neither have I. Hang glider pilots utilise the wind by exploiting
the rising air as it is forced over a hill or a ridge and
this forms a 'lift band' in front of the hill. The optimum
wind speed is around 10-20 mph for ridge soaring. Less than
this and it will be difficult to stay up and more than this
will make it difficult to penetrate into the wind. To answer
the question, what happens when the wind stops, the wind will
not just stop. It will decrease gradually and the ridge lift
will slowly reduce to the point where the glider will sink
to the ground at it's natural sink rate, roughly 180 ft per
minute.
What
is an Air Pocket?
It's just a laymans term for rough air. The
atmosphere is in constant motion as warm air rises and cooler
air descends, and when an aircraft passes through it, it often
gets bumped around a bit. But there's no such thing as an
'air pocket'.
I'm
scared of heights so how can I fly?
Well I'm scared of heights too. If I go up something
like the Eifell tower in Paris, I'm practically crawling on
my knees with fear and yet I can fly much higher than that
with no fear. I don't know why this is the case but I never
see anybody getting vertigo in an aeroplane so I guess it's
just the same on a glider. The way the mind perceives height
varies depending on where you are. Even going up a ladder
scares me. Fear of heights does NOT mean fear of flying!!
Do
you carry a parachute?
Yes. All hang glider pilots fly with a reserve
chute in their harness. It's the one piece of kit that you
buy and hope you never need it.
Where
can you fly a hang glider?
In theory, you could fly anywhere that you can
launch from. BUT.... in reality you really can't just go and
fly anywhere that you please. As with everything in life,
there are rules and regulations. The sky is divided up into
'Airspace' and the reason for this is that both civil and
military aircraft both have use of this space. They need to
know where they can fly, and at what altitude in order not
to collide with each other. As glider pilots we can use some
of this airspace but other parts are no-go for us. In order
to understand just where we can fly you need have a current
airspace map. These are a bit daunting at first but with a
little bit of tuition you can easily understand what they
mean. Any good hang gliding school or club will have access
to these maps and will offer tuition in the use of them.
The other consideration is land use. I live
in the UK and all the land is owned by somebody, whether it's
a farmer or the National Trust or whoever and they don't take
kindly to people using their land for recreational purposes.
For this reason we have hang gliding clubs all over the country
and these clubs negotiate the use of the land for hang glider
pilots to use. This usually involves payment for the use of
the take-off and landing areas and club membership fees are
used to pay for this.
Can girls do it too?
| Yes they can do it just as well as guys.
They may be put off initially by the weight of the glider
and feel that they can't lift it but it's not strength
that's needed to fly a hang glider, it's technique. Girls
actually tend to do better in the beginning than guys
because they don't try to muscle the glider around. They
have a lighter touch and they allow the glider to fly.
Guys tend to try to 'make' the glider fly in their first
few days of tuition and I have to always get them to be
more 'girlie' about it and be more sensitive to the wing
and the feedback that it gives to the pilot. |

Where
do I go to learn?
Look in your yellow pages, trawl the internet
etc and find a school in your area.
If you live in the UK, take this link
to the BHPA
web site and click on schools. You will find however that
it will be a long and frustrating road. Learning to fly in
the UK is not easy. There are very few schools and only a
few that are any good.
For those of you who are interested in tow-launching
or learning to fly in sunny Spain under a British Instructor
why not visit the Lejair
web site where you will find a school run by Tony and Rona
Webb. Tony and Rona are probably the most experienced tow-launch
instructors in the UK. I did my tandem aerotow course with
them and they were excellent.
If you really want to learn quickly and have
good weather to do it, go to Wallaby
Ranch in Florida
How
much does it cost?
I can only speak for the UK. To learn to hang
glide will cost around £750- £800 depending on
the school. This will give you around 10 days of instruction.
This is split into two courses, Elementary Pilot and Club
Pilot. You will then need a glider, a harness, a reserve parachute
and a helmet.
A beginners glider can cost from £500
upwards for a reasonable second hand machine to around £2,000
for a new model. A harness will cost around £250 - £300
for a good beginners model. A helmet is around £100
and a reserve chute is around £350. You may be lucky
to get a whole second-hand package from a dealer but ask around
first. Talk to pilots on the hill, ask them for some advice
on which glider is best for you, how much you should expect
to pay etc. Don't just buy the first thing that you are offered
by your school, they might just sell you the glider that happens
to be there that day, and it might not be the best deal out
there. There are plenty of dealers with lots of equipment
that they want to sell. Call them all and get the best deal
for your hard earned money. Naming no names but there are
some schools/dealers who will sell you any old crap for lots
of cash. So beware!!!! And remember where you heard it first.
Good gliders for beginners are:
Second Hand: Calypso, Target, Moyes XT.
- these gliders can be bought from around £500 to about
£1,200 depending on the condition. The Calypso will
probably be the cheapest option as they are older gliders,
but if in good condition, they are an excellent buy. Dealers
will have a stock of S/H gliders and you will also find ads
in Skywings which is the BHPA monthly magazine. You will receive
a copy of this mag if you become a member of the BHPA
New: Target,
Sting,
Fun, Rio.
- these gliders cost in the region of £2,200 - ish.
What
does it cost for an advanced glider?
New, advanced, high performance gliders will
cost around £4,000 for a flexwing and up to £7,000
for a rigid wing model. These are not to be considered unless
you have a lot of experience and skill. Don't even think of
moving up to these models before you are ready. You might
not live to regret it.
And now for the BIG QUESTION................Is
it dangerous?
|
Yes of course it is - relatively.
So is driving a car or crossing the street.
Life is full of dangerous stuff. Face
it! If you want to be totally safe, stay in bed. And
don't turn your electric blanket on - it could be dangerous.
BUT...
Actually to be serious for a minute, it's really only
as dangerous as you make it. So as long as you don't
do something really stupid then it's quite a safe sport.
I've seen a few accidents but all of them could have
been avoided. Most, if not all accidents are pilot induced.
They are usually a result of non-use-of-brain by the
pilot. The same way as car accidents are usually driver
induced. The thing you have to realise is that things
don't just happen to you out of the blue. You are
usually to blame for your own accident.
Take note - all you ambulance
chasing lawyers out there. In hang
gliding you have to learn to take responsibility for
your own actions and make your own decisions about the
conditions that you fly in. Dont try to blame someone
else for your own stupidity !!
Hindsite is a great thing but foresight is an even greater
thing. Looking ahead to what might happen is often the
best way to avoid an accident.
Hang gliders are very safe aircraft. They
are very stable, slow to takeoff and land and very responsive
in pitch and roll. They are constructed from very strong
materials and tested to 6G positive and 4G negative.
(a jumbo jet is only tested to 1.5G positive). Hang
gliders are in short, very safe. It's the pilot who
is dangerous, usually to himself.
ps. With regard
to the latest fad in the UK for suing someone if you
happen to be stupid enough to fall over.
if anyone comes
to me for hang gliding tuition and I find that they
are in anyway connected to these 'no-win, no-fee' ambulance-chasing,
blood-sucking leeches who call themselves lawyers, then
I will refuse to teach them. Even if they are just the
secretary or the cleaner who works for those companies.

What's the difference between a hang glider and a paraglider?
 |
 |
| Hang Glider |
Paraglider |
The obvious difference is the wing shape. A
hang glider has an aluminium frame which supports the sailcloth
and uses internal battens in the wing to define the aerofoil
shape. You can clearly see the aluminium frame and battens
in the hang glider (above), whereas, in the paraglider there
is no internal structure. The wing is simply 'inflated' by
air pressure in the cells.
The main differences are ::
Hang gliders are faster in the air and have a much superior
glide.
Hang gliders weigh around 35 kilos and pack down to around
13 feet long. (2meters -ish)
Hang gliders take a fair bit of skill to fly and it takes
a couple of weeks to learn the basics.
They require the development of good co-ordination skills.
Hang gliders do not collapse or break up, unless subjected
to extreme conditions such as tumbling due to unsuccessful
aerobatics or from collision with another glider.
Paragliders are slower in the air than hang
gliders and have an inferior glide.
Paragliders weigh about 15 kilos and pack into a large bag.
Paragliders are very easy to fly and this makes them very
popular.
Paragliders collapse in rough air and you will fall very quickly
to the ground.
Surely paragliders are safer than hang gliders aren't they?
NO. NO. NO. Repeat these words until you
understand completely that they are NOT.
A paraglider looks similar to a parachute to the untrained
eye and people assume that they are inherently safe. They
are not. They will collapse in rough air and you will fall
very quickly to the ground. This will usually result in either
serious injury or death. Anyone who tells you that they are
safe is lying. Schools make a lot of easy money from teaching
people to paraglide but don't properly explain to them just
how dangerous it really is. Our club, the Southern Hang Gliding
Club, lost a member very recently - 27/07/03. She died of
multiple injuries after her paraglider collapsed at Devils
Dyke. She was a very good pilot with many years experience
but her wing collapsed in rough air and gave her no chance
of survival. She will be very sadly missed by many people.
If any other form of aircraft was prone to collapsing
and killing it's pilot it would be permanently grounded. I
believe that people should only fly paragliders in very smooth
and benign conditions. Anything other than that and the pilot
is at serious risk of losing his or her life. Paragliders
are very, very dangerous aircraft. When things go wrong, they
usually go wrong very quickly. Unfortunately with serious
consequences.
On a final note about the dangers of paragliding.
Schools will tell you that you can take avoiding action when
your paraglider collapses. They will take you on SIV courses
where you will fly off a mountain and learn to deal with tucks,
spins and collapses, all at around 3 thousand feet above the
ground where you can't hurt yourself. The thing is that when
it happens in real life you are usually around 100 feet above
the ground and it's the ground that hurts you. You don't have
time to react at this height. I know too many good people
who have died or suffered awful injuries on paragliders and
I will never ever fly one.
I do admit to being very biased on this subject but not without good reason.
