| Inc alruneS WHICH now are DelIlB
forced to replace equipment find avail
able a number of new transport planes
incomparably better than those of three
year ago. Higher speeds, greater pas
senger comfort, increased safety and
augmented efficiency have been at
tanned in the new models.
Cruising speeds have mounted past
$50 miles per hour and now are ap-
preaching the ITS and 180 mile per
hour class. Reduction Of coaSt-to-co ast
schedules to less than a day Of travel
now Is possible, with corresponding
time saving on all the Nations main
airlines.
Forerunners Of a great fleet of &c
new Boeing high-speed, twin-engined
monoplanes have gone into service on
the transcontinental system OF United
Air Lines. making possible a prelim-
mary revision downward of fying-time
schedules. The effect has been felt in
the National Capital, Pennsylvania Air
lines having been forced to revise its
schedules out of Washington Hoover
Airport to conform to the United sched-
ules at connecting points.
Fast new Curtiss CondorS OF the type
which recently went into service on the
Eastern Air Transport line through
Washington have been put on duty on
the American Anyways New York-Ch1-
cago line, in preparation for the eStab-
lishment Of a f1ve-hour schedule be-
tween the two great cities by way OF
Buffalo and Detroit.
Transcontinental and Western Air Is
studying the new models and Col
Charles A. Iindbergh, technical adviser
to the line, had as one of the main pur-
poses behind his recent transconttnental
trip the inspection Of new twin-en-
gined Douglas transport comparable to
| the new Boeing and single-motorec
Northrop with a reputed cruising speed
of more than 180 miles per hour.
| Cord interests are beginning tests o.
a single-engined monoplane which Il
expected to have a cruising speed ol
better than 100 miles per hour with g
pay load of 5000 pounds. The nrs'
multi-motored Lockheed airplane evel
built, embodying many innovations, Il
approaching the production stage, VI

whose racing planes have been SEN

Races for three years, are coming ou'
with an exceedingly fast eight-plact

Blind Landing Need Stressed.
The Importance of recent develop
ments in the fields of instrument flying
a.; blind landing as contributions to
safe, reliable air transport operations
has been stressed strongly by the De-
partment OF Commences Liaison Com
mittee on Aeronautic Radio Research in
the third report which it has made
since its creation four years ago.
The committee declared that the
value of these methods Of progress
toward emancipation from weather
conditions cannot be emphasized too
strongly" It was pointed out in the
report that hundreds of completely
blind landings have been made by
means of the system installed by the
Department of Commerce aeronautics
branch at College Park, Md, and, more
recently, at Newark Airport, New York
transport terminal. At Newark land
ings have been made with the aid Of
the radio blind landing system during
conditions of fog which kept all reg
ular air traffic on the ground.
The committee reported that during
the interval since its second report was
issued on October is, 1881, there has
been a marked increase in instruments
possible. This was made possible by
availability Of improved instruments,
such as the artificial horizon and gyro-
compass and the increasing use and de-
