MNRINF NAVIG ATI0N METHODS
WILL BE USED BY BROWN

st. Johns, n F.. June 14.-Ry hp-
plying methods Of marine navigation
to an air flight, Lieut. Arthur Written
Brown eXnects TO fly across tho At
lantic in the Nimv bomber machine
piloted by Cant. Jack Alcock. and to
make landfalr within twenty or
thirty miles of his objective in Ireland
or England.
Lieutenant Brown was an American
electrical engineer before he Joined
the British flying service in 1914. He
has described in a statement which he
has prepared for the Associated Press
an interesting description of the diff
ficulties encountered in a transact
lantic flight and the methods by which
he hopes to overcome them.
In flying an airnlane over large
bodies of water such as the Atlantic
ocean, where the pilot may be for
hours out of sight of any landmarks
by which he could judge his position,
it Is to the methods of navigation
which have been developed by the
mariners that the pilot turns to learn
where the location and the course to
his destination is" writes Lieutenant
Brown.
Wind Must he Considered.

slow albeit accurate. means of calcu-

sequence. special charts have been
devised for use with the sun or stars

This however. he Will not be able
TO do unless he keeps careful watch
on the direction and strength of the
wind which may alter between his
and without his knowl-
edge, In order 10 check this. an in
known as the drift indicator
has been devised. by means of which
the nilot can ascertain the direction
of the wind. and the speed at which
he is travelling over the ocean, so long
as he can see the ocean and the flares
or SNAKE bombs which he drops into
If for the nurnose of making his OBJ
