News of the Month

NEW AIRLINE SCHEDULES HOURLY passenger service at minimum rates, approximating those of the railroads, is planned for the middle west for the coming summer. Plans have been announced for a group of lines, with the same general characteristics as the New York-Philadelphia and Washington Airway, to link Lincoln, Detroit, Chicago, Cleveland, and probably St. Louis, Kansas City, and various other cities.

ORGANIZING AIRLINE MAINTENANCE

TO GAIN public acceptance of air transport equipment must be kept in a condition which is no perceptible degree short of perfection. If the equipment of a transport system, air or otherwise, is properly maintained it is possible to operate to schedule, to gain public confidence and build up patronage, to hold costs to a minimum, and to earn a profit.

EVERY HOUR ON THE HOUR THE rule of frequent departures, inaugurated by the New York-Washington Airline and now to be emulated in the Middle West, has brought into air transport a change far more fundamental than is commonly realized. The running of an hourly plane does not meruly increase the volume of operation.

Transport and Engineering

WIND channel and other tests show that the resistance of two bodies in close proximity to one another is rarely equal to the sum of the resistances of the two bodies when isolated one from the other, and yet performance estimates for new planes must necessarily be based on the complex summation of the resistances of a large number of parts.

THE PLACE OF PRESSURE DISTRIBUTION TESTS IN STRUCTURAL DESIGN

A GLANCE at any of the more recent surveys of the causes of airplane accidents will disclose that structural failures have been responsible for hut a small proportion of such accidents. This immediately suggests that the structural design rests upon fairly solid foundations and implies that considerable improvement must have been made, since the earlier days of the airplane, in our knowledge of the external loads coming into play on aircraft structures and of the properties of the materials used therein.

ENGINE SERVICING AND SERVICE ORGANIZATIONS

ACTUAL servicing of aircraft engines begins at the factory, for every engine is subjected to a period of running of from four to six hours at gradually increasing power, the last two hours being run at ninetenths rated load, which is well in excess of the normal load at cruising speed.

THE 1930 PARIS SHOW . . . EUROPEAN AND AMERICAN PRACTISES

HELD once more in the Grand Palais des Champs Elysees, the Paris Aero Show, twelfth of the series, attracted, between Nov. 28 and Dec. 14, much bigger crowds than ever before. Notable representation of eight nations gave it unusual interest: the coming of the first International Congress for Air Safety added a note which was favourably commented upon by the general public.

AVIATION CLUBS IN THE COLLEGES

COLLEGIATE interest in aviation, at present demonstrated at 34 colleges in the form of engineering study, ground school courses, and flying and gliding clubs, is by no means a novelty. There were eighteen college clubs in 1910, resembling each other in their sporting interest in flying, and technical interest in experimental designing.
