A PRE-VIEW OF THE DETROIT SHOW

FROM the plans of the group of exhibitors at the Detroit Aircraft Show it is possible to glean some impression of the ideas of the manufacturers, if not of the actual trend of the industry. Of prime importance is the indication that the light airplane has ceased to be a curiosity and become an integral part of the industry.

SERVICING AIRCRAFT INSTRUMENTS

THE maintenance and servicing of aircraft instruments is one of the newer phases of aircraft operation. With one or two notable exceptions, it is only within a comparatively recent time that those charged with the upkeep of flying euipment have realized that periodic attention is required by the instruments as with the engine and other parts of an airplane.

IN the "Dolphin," the Douglas Aircraft Company of Santa Monica, Cal., offers for the first time in its history an airplane designed primarily for commercial use. The machine is a twinengined amphibion monoplane designed to fill the requirements of the private owner, but also readily adaptable for use on commercial airlines and for certain requirements of the Army, Navy or Coast Guard.

EDITORIALS

THE personnel of the aircraft industry are in the habit of thinking of themselves as a special case, to which no previous experience applies. Many of them men whose business life has been limited to the aeronautical field, and who are still under the spell of the spectacular and violent changes of the last thirteen years, they feel themselves to be apart from the general body of industrial history.

TOURING EUROPE BY PRIVATE PLANE

THE American pilot, flying from state to state within his own country, does not realize how fortunate his position is with regard to freedom from governmental control and interference. He may be asked when he lands at an American airport, to sign the register, stating his name, arrival and departure, etc., although even this is sometimes overlooked.

THE NATIONAL AIRCRAFT SHOW OF 1931

THE National Aircraft Show has become one of the important fixtures of the American aeronautical year. Coming as it does during the second week of April it might well be considered the opening of "the flying season." Always important as a meeting place for the industry, this year’s Detroit show, the only one of major dimensions scheduled for 1931.

Transport and Engineering

THE use of cowlings of the N.A.C.A. or Townend type on radial aircooled engines driving tractor propellers has been well established, and there is no lack of published test data to indicate the improvement in performance to be gained by their application.

THE SHOW FROM THE SALES MANAGERS' VIEWPOINT

IN THE long run national exhibitions in any industrial field can justify themselves only as they are successful in effecting sales of the products exhibited. As individuals primarily responsible for sales policy, the sales managers of exhibiting organizations have a very direct interest in the conduct of any show.
