The author, who was formerly manager of the transport section of the Aeronautical Chamber of Commerce, has discovered some fundamental principles that should be of interest to those who are charged with the duty of dressing up the ticket office windows.

MENTION window displays to any group of airline traffic representatives, advertising managers or operating executives and you’ll bring out as many divergent views as you might expect to obtain through an inadvertent mention of the “commodity dollar” among a group of economists or bankers.
Controlled engine cooling through adjustable cowling
AMONG the many subjects touched upon by Messrs. Beisel, MacClain and Thomas, in their excellent paper “The Cowling and Cooling of Radial Air-Cooled Aircraft Engines” (presented at this year’s annual meeting of the Society of Automotive Engineers in Detroit), is a study of the control of cooling air by means of trailing edge flaps applied to engine cowling of N.A.C.A. type.
HIGH NOON on April 20. A private office on the fourth floor of the old Post Office Department Building in Washington. Into the room, crowded 150 people, treading on each other’s toes and poised precariously on every piece of furniture that would give a vantage-point.
The third article of a series on the definition and control of cruising conditions

CONVENTIONAL performance testing of an airplane consists essentially of the accurate determination of two sets of maxima, maximum climb-rate and maximum level velocity at all altitudes within the airplane’s range. Aside from the technical difficulties inherent in measuring true maximum values with the required precision, a further obstacle arises in the constantly shifting properties of the earth’s atmosphere.

AT A TIME when the aeronautical industry is experiencing the worst weather in its history, with showers of dead cats and low-hanging political fogs reducing operating conditions to practically zerozero, considerable encouragement can be derived from reviewing the great technical advances which have taken place during the last year or so, not only in the design of aircraft but also in general improvement in efficiency and economy in the maintenance and servicing facilites on the ground.
UPON Capitol Hill in Washington air transport is a familiar subject, and never more familiar than during the past three months. Aircraft manufacture has an accustomed ring in the ears of Congressmen who have received proposals for five-year programs and the like and have referred them to committee and debated them to and fro ever since ’way back before the War.
A question of considerable importance to the airplane pilot
THERE are few airplane prospectuses or specifications that do not contain some such words as “the vision from the pilot’s seat is practically perfect,” or at least “practically unobstructed in all essential fields.” Unfortunately such statements are virtually meaningless, for heretofore there have been few available means to analyze pilot vision quantitatively.
China becomes one of the World’s great aeronautical frontiers and one of the greatest of markets
CHINA has too long depended upon its few great rivers for contact with the outer world and its maze of canals for internal communication. With a nature not easily given over to radical change, she has been rather reluctant in availing herself of the Western automobile and locomotive.
VIEWING WITH ALARM is a distasteful pro cedure, and one which is always a pleasure to stop. Unfortunately we have had a lot of it to do in the last two or three months, and it is with profound relief that we seize on the chance to herald the end of the head-shaking period and the coming resumption of orderly development.
THE INTERNATIONAL BODY that deals with aviation as a sport and with the certification of aircraft performances recognizes today 21 records for land planes (not counting the various light-plane classes) and eighteen for seaplanes. Of that total of 39 established figures, only six stand to the credit of the United States.
VISITORS to Langley Field in the years immediately following the War will recall that for a long time a pursuit airplane stood just within the gate as a sort of trademark. Always it was a machine long obsolete and condemned as unfit for flying, but always it presented a pleasantly shiny appearance to the casual visitor.
WHEN attempts were first made to build airplanes with metal, the first disposition of designers was to put a piece of metal wherever there had been a piece of wood, and to conform as exactly as possible to the structure with which they had grown familiar.
ON MARCH 30, two days after Postmaster General Farley’s announcement that the air mail service would be returned to private contractors as soon as possible (AVIATION, April, page 118), the Post Office Department issued advertisements for temporary bids for 21 routes, and followed them with a second set of advertisements for four additional routes one week later.

[One of the minor excitements of Washington during the past three months has been the persistent attempt to put into the widest possible circulation a series of “charts” prepared by Mr. Chessborough J. H. MacKenzie-Kennedy and purporting to prove the hopeless inferiority of American aircraft and engines to those of European design.
TO many travelers, the idea of spending a night in an airplane is far from new. it has remained, however, for the Curtiss-Wright Airplane Company, working in close co-operation with American Airways and Eastern Air Transport to translate 70 years of railway sleeper experience into the air.
AFTER an extensive survey of the requirements of potential private owners, Fairchild aviation officials came to the conclusion there is a definite place in the American market for a machine between the two-place, highspeed cabin class and the more luxurious four to six-place ships.
AMONG photographs recently released by the Navy Department, are two which show the trend of latest sea-going flying equipment. In the fighter classification, the Curtiss XF11C-3 shows a number of interesting details, among which perhaps the most important is the fully retracting landing gear.
EASILY recognizable as a member of the Monocoupe family, but carrying numerous features that heretofore have been reserved for the racing classifications, the Model D, with its 145 hp. Warner Super-Scarab engine, offers a number of refinements of interest to the sportsman pilot.
<p>THE GA-43 transport is a wanderer in the far corners of the earth. The first machine delivered flies the rugged Alpine routes for Swissair, the second travels the airlines of Japan. Another shuttles back and forth over General Aviation’s Mid-continent Division, between Cheyenne and Albuquerque, and the fourth, just completed, is destined to serve the Magdalena River country in Colombia (S. A.), for Pan-American controlled Scadta Airlines.</p>
A STANDARDIZED annual of this sort must follow very much the same form year after year, and it is hardly possible to find anything to distinguish the current volume in principle from its predecessors Like them it will be accepted as a necessary tool for constant use by every engineer and constructor of aircraft and engines, by all writers on aeronautics or students of aeronautical developments, and by large-scale operators who want to compare their own activities with those of similar enterprises in other countries.
THE inspection, repair and cleaning of the upper wing panels of large biplanes is always a problem due to their relatively great height above the floor of hangars. It will be recalled (AVIATION, February, 1933, page 62) that a sort of bosun’s chair device was suspended from an overhead trolley rail in the Cheyenne shops of United Air Lines for convenience in getting at the top wing surfaces of the Boeing 80s formerly in use.
WHEN regrinding engine cylinders it is frequently difficult to get sufficient light inside the barrel to see clearly the condition of the finish. This problem has been eliminated in the engine shop of Transcontinental & Western Air at Kansas City by mounting an ordinary automobile headlamp on the spindle carriage of the Heald grinder with the beam focused into the open end of the cylinder.
OPERATING under unusually severe weather conditions in countries where hangar facilities are few and far between and where schedules may be temporarily halted on account of weather, Northwest Airways has had to develop a lightweight engine heating plant which can be carried in the ship at all times.
MECHANICAL personnel in the shops and service stations of Transcontinental & Western Air wear certain insignia on their working clothes to indicate their ratings. Overalls are white and carry in the middle of the back the company insignia, the letters T.W.A. in a circle, done in red.
