THIS paper deals primarily with the considerations affecting the airplane design, leaving discussion of operations to the operators. The big probable field for air cargo lies in the transportation of perishable and relatively high valued classes of goods. The structural design of floors, tie-down equipment, and the like, is shown to be basically dependent only on the maximum allowable cargo load and the maximum available cargo volume. Analysis shows that the actual operations of the cargo airplane determine the relative importance of speed of loading and weight. Speed is essential in short-range operation, but minimum weight is essential in long-range operation. In conclusion, the author suggests that reduction of rates can make air cargo a really big business, capable of affecting the prosperity of our country and the rest of the world.

JAMES B. KENDRICK
MR. KENDRICK here shows ways in which improved engineering and better cooperation between engineering and operations personnel may serve to reduce the air cargo rates. This investigation of air cargo planes consists of the following general topics: 1. Some fundamentals of cargo plane design and economics, to permit an evaluation of the relative importance of various factors. 2. The engineering aspects of some of the problems of operation that must be considered by the maintenance and operations personnel. The first step toward providing good service at low cost will be accomplished automatically by the establishment of regular cargo service. The next step is to bring about greater cooperation between the operators and engineers, to inoculate the engineers with the importance of convenience in handling and maintenance.

KARL O. LARSON
THE handling of the three classes of cargo - unpackaged light pieces, unpackaged heavy units, and packaged goods in different shapes - requires, Mr. Larson says, greater simplification and standardization. Containers used for surface-shipped goods are generally too heavy for air cargo shipping, and lighter paper or fabric covers or containers are desirable. New materials for this purpose, he says, are being tested. Mr. Larson discusses the advantages of pallet loading with a lift truck. The pallet may be bolted to the floor, thus eliminating strain of lashing. Parking space requirements for a medium-sized cargo plane are about 150 ft square. A terminal of 10,000 sq ft to handle cargo from this size ship would require a 70-ft wide building one-story high, and 150-ft along one edge of the berth. These figures are based on 12 loadings per day. For each additional berth, the terminal must be extended accordingly.

⋆ ⋆ ⋆ IN the enormous increase in air-cargo transportation predicted for the near future, good schedule reliability is an absolute need. If schedule reliability is not maintained, it will be impossible to make close connections with other air carriers and time thus wasted would overcome many of the advantages of shipment by air. To attain such schedule reliability, cargo airplanes must be equipped with all the facilities needed for operation under adverse conditions, including anti-icing equipment and a full complement of radio and other necessary instruments. The purpose of this paper is to indicate probable design and performance trends and to outline some of the specific problems of carrying air cargo. The conclusions drawn are based upon an actual research study of cargo airplane performance and design criteria, and upon present airline cargo handling experience. These conclusions indicate that present methods and equipment are wholly inadequate for any great extension.

THIS paper shows that the growth of electrical demands on planes is due mainly to the problems encountered in operating the planes and, hence, electrical systems are the chief concern of the plane operators. Existing electrical systems are discussed from the standpoint of the operator, under the headings of “trouble,” “weight,” and “facilities.” A new system is described for the plane of the future, which is assumed to have a gross weight of about 100,000 lb, and a power demand of 30 kw. By means of variable-frequency systems a considerable weight saving is forecast.

THE information given in this paper was obtained principally from trip icing logs and test flights conducted on a major transport system. A copy of a trip icing log is included to show the type of information obtained from normally scheduled flights. The different types of ice formed are explained and the general effect upon the performance on the airplane for each type of ice is stated. Airplane ice accumulations are divided into two major classes: (1) Those producing a loss of flight performance and (2) those which serve as an annoyance to the crew. The main portion of the paper deals with these two classes, explaining when, how, and why they are of importance. Numerous pictures are shown depicting the various conditions which were found to exist in scheduled airline operations and the shortcomings of the present anti-icing equipment is explained. Consideration is given to ice accumulations on the wings, empennage, propeller, pitot mast, radio loops, windshield, and so on.
