There is considerable

In

the

United

Kingdom where gliding conditio

ns

re

usually

only moderate, ave

rage speeds rarely exceed

65

m.p.h.

but in

those

parts of

the world where gl

iding

conditions

can be

really good, speeds of

over

1 0 0 m.p.h.

are

being

achieved

and

both

straight line and closed circuit distance

flights only

just

fall

short

of

1 0 0 0

miles.

Naturally

not

everybody

feels

the

need

or has

the

temperament

for

cross-country

fl

ying. Many pilots re perfectly happy flying

about

well

within range of

their

hom

e sites,

c

arrying pasengers,

instructing

or getting involved with

glider

mainten

ance,

construction or

repair.

Whatever

your

in c

lination,

gliding ho

lds

m u c h of

interest and

excitement

and you

will

be

left to find

your o w n level of

amusement without any

pressure

being ap

plied to you.



B S IC

P R I N C

IP L E S

Most

people view

gliding

as

being one

of

the more te

chnical

sp o

rts. S

ince

not everybody

is

particu

la rly technically inclined

m a n y dismiss

th e

sport

on the grounds that

they

will

not

be equal

to the

considerabl

e amount of

th eory

wh ich they

assume they will

have

to learn. But

desirable as theory may be, gliding can

be

taught

perfectly safely on

a ca

use and

effect

basis, in m u c h

the

sam e w

ay

that

you can be taught to dri

ve a car without

understanding

w h at

goes

on

under

the

bonnet .

Grasping the

basic

principles

is

simplicity

itself

i f

we use

analogies

w ith

which we

re familiar in everyday l i f e ; which is

what

we

sha

ll

do.

The glider (bette

r

perfo

rmance machines are

sometimes

referred to as sailplanes) is noth ing m o

re nor less than a re

fined

p per dart.

In still

air conditions

having

been

launched

t o

a

given

height

i t

will m ove

forward horizontally relatively

rapidly

and

descend

vertically relatively

slo wly,

behaving

exactly as our

p per da

rt

w ou

ld

i f launched across

an empty ro om. t can be

turned

during

its descending

flight, or

its

glide path can be

steepened,

bu

t

its

glide path remains

essentially downwards.



The

beha

vio ur of the g

lider is

exactly

s im

ilar to

that of

a

cy

clist

freewh

dow

So

all our glider

pilo

t has to

do is

to find so

m e air

going

up

fast

er

th

an he is

g

oing

d

own and

h

e wil

l rise.

The

p

rinciple

is

exactly

t

he s a m e

as a

m

an t

rying to

walk

down a

n

up

gomg

escala

to r.

I

f the esca

lator is

going up

fast

enou

gh, th e

n

i

n

spite

of

his

efforts,

the m an

will

be

carried

to

the

top.



N o w where and how does

the

glider pilot find

rising

air

known

simply

as LIFT)? H e

or she

cannot see

what is

invisible

so

how

is

i t

done?

I t

would be

nice

to say

i t

was easy

but

i t takes

quite

a lot of

practice before

a glider pilot

learns to find

and use

l i f t

successfully.

S O U R E S O F

L I T

There

re

three

main

sources

of

l i f t

which the

glider

pilot

can

use.

The strength

and extent of

the

l i f t will

vary

considerably,

as will its

character,

such

as whether i t is

rough

or

smooth.

i l l l i f t

I f there is a wind blowing and there is an obstruction to the

wind such as a mountain or

range

of hills, since the

w ind cannot

go through the obstruction, most of

i t

is forced over the

top

and

in

doing

so

a

band

of

rising air

is

formed immediately

in

front

of

the

hill. Provided

the

glider

pilot

keeps flying within this band

of

l i f t he can

stay up all

day and

all night

in theory) i f he

wishes,

so

long

as the

wind keeps blowing strongly enough

and

in

the right direction.

OMP TITIONS

M a n y glider pilots

re

quite happy just flying

about

locally

or

doing cross-country flying primarily

for the pleasure of vie wing

the

landscape

from a m

ore

interesting

vantage

point .

B u t there

re

inevitably

some

pilots

of

a

more

competitive

frame

of

mind

w h o

have the

ur

ge to compare their

performances against those

of

other pilots.

Such an attitude will eventually

lead them

into th e



compet

ition struct

ure of the

B

ritish

gliding

m ovement and i f

they

re

ex

ceptionally good

into

internationa
