Vnlch was felt a year ago. That
not be a general effort through

Authority for present use of the Los
Angeles restricts the ship to non-fiiglt
status, although she actually is in q
condition capable Of fight. It is
planned to moor the ship out for ex-
tended periods at the mooring mast
to demonstrate the ability of a moored
airship to Withstand a wide variet.
of weather conditions.
1t also is planned to install a num-
Der Of instruments for the collection
Of data as to loads imposed on an
airship structure by various wind and
weather conditions. The old airship
has not been placed in commission.
Brazilian Cut-Of Surveyed.
Announcement that a new empire
building airway" bisecting Brazil ard
cutting hundreds of miles of the in
ternational airways between the
United State and lower South America
has been surveyed. is made in a spe-
cial dispatch received from Rio de
Janiero.
The projected route, which would
eliminate flying the long coastal route
around the Brazilian hump" would
open a great interior area Of Brazil,
rich in agricultural and mineral re-
sources. 1t would bring the northern
most provinces of Brazil, now 10 days
distant from Rio de Janiero by sur
face transportation, within single
day of the Brazilian capital and at
the same time would provide a much
faster route direct to Rio and the
markets Of Southern Brazil, Eastern
Uruguay and Argentina.
The new route, according to the
Brazilian dispatch, has been surveyed
by Pan-American Always, in CO.
operation with Brazilian authorities.
The route would open to Pan-Amer-
lean an area not even remotely ap-
preached by its rival European air
lines and would give United States
foreign air transportation a decided
advantage on the South American
east coast.
The survey was made in O Pam
American Always airplane in charge
of K. M. Blotner. survey engineer,
with Capt. H. L. Turner as pilot. This
ship now is in Para after negotiating
the first inland passage by an air
transport plane between Rio and the
distant Amazon River, project which
has been given a great deal Of study
by Pan-American Anyways and the
Brazilian government since 1880. The
aerial survey followed a ground eX-
ploration trip made in 1881 by an
expedition in charge of Blotner and
Maj. Lysias Rodriguez of the Brazilian
government.
From the findings of the pioneer
ground expedition and subsequent
studies by the airline and the govern
ment. the first authoritative maps Of
the region were drawn and used as
basis for the flight survey.
The ground and flight expeditions
succeeded in exploding the time-hon-
ored belief that interior Brazil was a
maze of jungle, inhabited only by saw
ages. according to the dispatch. The
area. it was found, contains valuable
farm and pasture lands and is for the
most part rolling, open country. Great
navigable streams extend through the
area
1t is understood plans are being
made for construction of an airway
through the area by Pan-American
Anyways in cooperation with the Bra
lillian government.
Great Circle Chart Issued.
Plotting of cross country flights with
the greatest possible accuracy is made
easier with new type of great cir
Gle" chart of the United States which
has been printed by the Coast and
Geodetic Survey for the Bureau of Air
Commerce
The ordinary type of map. on the
so-called Lambert projection. is not
suitable for the easy plotting Of a
great circle course, the shortest pos
sible distance between two points on
the earth's surface. because it is not a
true representation of the curved sur
face of the earth.
"On the new map" the Bureau of
Air Commerce explained, any straight
line is a great circle on the earth. A
line between any two distant points
on the new map may be transferred to
any other type of map by means of
the places through which it passes"
The great circle chart is based on
the gnomic projection and is said to
be the solution to many problems of
the distance flyer who wishes to travel
from point to point over the shortest
path. The chart is as simple as pos
sible, showing State boundaries, the
largest rivers, principal cities and i'm
portant airports in their correct geo.
graphic positions.
This map" it was explained, will
have special appeal to airline execu-
tives planning the reduction of flying
time of air transports over the length
and breadth of the country. 1t will be
of undoubted value in the air defense
of the country, as 1t can be used to
determine quickly the proper line Of
flight for a fleet of airplanes to any
desired point when rapid mobilization
is necessary"
