A STUDY of possible economic advantages to the aircraft operator of utilizing the internal cooling potentialities of water to assist aircraft-engine cooling and increase detonation limited powers is presented here. Cost analysis is made of three methods of increasing airplane performance by water injection, namely: 1. By increasing cruising bmep's while maintaining engine cooling requirements at the value for conventional cruising bmep's. 2. By decreasing cruise power cooling requirements with the addition of water. 3. By increasing cruise powers up to meto at a constant F/A ratio while maintaining low cooling requirements and avoiding detonation with the use of water. It is concluded by the author that if the water to be used for cooling does not displace an equivalent weight of payload, a maximum saving of 7% at sea level and 18% at 25,000 ft can be realized in direct operating cost with water.

FLOYD PATRAS
THE extensive reconditioning of parts that was practiced during the war will slowly be cut down as new parts again become plentiful. Then, Mr. Patras explains, the deciding factor will be cost. The rule as he practices it is: Recondition used parts wherever satisfactory service can be obtained from the reconditioned part and the cost of reconditioning is equal to or below the cost of a new part plus freight and handling. In addition the author suggested that improvements were particularly required in certain specific items, such as steering gears, oil seals, oil pumps, and oil pressure regulating valves. He explained further that if designers were to utilize to the greatest extent possible units and parts already in volume production, the inventory problems of the modern motor bus operators would be greatly simplified, and the cost of repair parts could be just that much less. The shortage of skilled mechanics is also discussed by Mr.

MR. VANIK discusses the limiting effect of maximum stalling-speed requirements on efficient design of high-speed transport airplanes and shows that deletion of this requirement would result in no difficult operational problems. He also shows that retention of fixed stalling-speed requirements will result in placing American manufacturers and operators at a serious disadvantage in the international field.

PRESENTED here are the numerous factors which an airline must consider in choosing a new type of transport airplane. The authors show how various considerations influence this choice and how, under some conditions, certain of these factors may assume more importance than under others. They also include charts and tables showing how some of the variables may be predicted.

ANALYSIS of engine cooling failures indicates the need for a special study of the automotive cooling system from the standpoint of design and construction, as well as of maintenance. Mr. Green carries out such a study here, discussing, in turn, the factors entering into each type of failure.

THE dependability and regularity of airline service hinges, to a large extent, on the efficiency with which the job of maintaining the aircraft and their accessories in top-flight condition is accomplished. The maintenance of aircraft is now a precise and exacting science, extending from the creation of a design through the operation by the crew assigned to fly the plane - and, Mr. Stunkel shows, the maximum usefulness of any airline aircraft can't be attained unless the maintenance program is carefully tailored to fit the operations for which the aircraft is intended.

This Aerospace Standard establishes an identification system and provides design and tolerance information in describing two series of image quality indicators currently used in radiography of aerospace components, especially in electronic component evaluation and radiographic film and paper classification. Individual image quality indicators (IQIs) are classified by use of this standard number, followed by appropriate codes. Synopsis of the classification system is: AS 1613-A-XX IQI, with six tungsten wires; and AS 1613-B-XX IQI, with six tungsten wires and six lead beads.
