COMMANDING OFFICER Signal Corps Aviation School Hazelhurst Field MlNEOLA, L. I. 320741 PREFACE - As there are numerous young men training in this country, both in ground schools and at flying fields for the aviation service, and as much of this will probably be performed in France, it seems desirable to compile a brief glossary of commonly used aviation terms in both French and English to facilitate intercourse between the pilots and mechanics speaking different languages who work together in the present emergency. These lists are enlarged from a briefer series prepared originally for use in teaching classes at the Signal Corps Aviation School, Miûeola, L. I. The illustrations accom- panying the text should make everything clear about which any doubt could exist. As no definitions are given, the booklet is more in the nature of a glossary or list of words than a dictionary, and is intended only for use of those already familiar with aviation. Some of the equivalents may not be literally correct, but are selected with a view to listing only terms in common, everyday usage. The painstaking work of Lieut. Paul Montariol, of the French Flying Corps, assigned as instruction officer at Mineola, L. I., has been of great value in furnishing French equivalents and insures that these will conform to the accepted practice abroad. It is believed that this 9 10 PREFACE compilation will be of some value in securing closer co- operation and more intelligent discussion of aviation subjects between members of our oversea aviation forces and our non-English speaking allies.

The Metric System is based on the Meter which was designed to be one ten-millionth (rcroWa) Pf rt of the earth's meridian, passing through Dunkirk and Pormentera. Cater investigations, however, have shown that the Meter exceeds one ten-millionth part by almost one part in 6400. The value of the Meter, as authorized by the U. S. Government is 39.37 inches. The Metric system was legalized by the U-S. Government in 1866. The three principal units are the meter, the unit of length, the liter, thtf unit of capacity, ana the gram, the unit of weight. Multiples of these are obtained by prefixing the Greek words : deka (10), hekto (LOO), and kilo (1000). Divisions are obtained by prefixing the Latin words: deci (fV). centi ( T lta)» ancl. milli (nfrç). Abbreviations of the multiples begin with a capital letter, and. of the divisions with a small letter, as in.the following tables : Measures of Length 10 millimeters (mm.) — 1 centimeter (cm.) —.3937 in. 10 centimeters....'. = 1 decimeter (am.) 10 decimeters — 1 meter (m.) =3.28083 ft.— 39.37 ins. 10 meters ; -. = 1 dekameter (Dm.) 10 dekameters = 1 hektometer (Hm.) 10 hektometers — 1 kilometer (Km.) . ...... . .—0.62137 mile lfoot =- .3048meter linch — 25.4 millimeters Measures of Surface (not Land) 100 square millimeters (mm. 2) = 1 square centimeter (cm. 2)=- 0.155 sq. in. 100 square centimeters = 1 square decimeter (dm. 2) 100 square decimeters = 1 square meter (m. 2) — 10.764 sq. ft 1 square yard = .836 square meter 1 square foot = .0929 square meter 1 square inch = 645.2 square millimeters Measures of Volume 1000 cubic millimeters (mm. 3) «1 cubic centimeter (cm. 3) — .061 cu.in. lOdOcubic centimeters =1 cubic decimeter (dm. 3) =1 liter— 61 .023 cu.ins.
