1. Purpose and scope.-a. The purpose of this manual is to pro-

vide, in convenient form, a review of some topics of mathematics and

related material which the air crew trainee must understand.

b. Sections I through VII include the elementary operations of

arithmetic, such as addition, subtraction, multiplication, and division;

percent; ratio and proportion; algebra; angular measurements; scales;

the use of graphs and formulas; and the graphical solution of the

more common problems inv.ving the triangle of velocity.

c. Sections VIII to XIII inclusive, provide additional instruction

material for the required mathematical background of air crew trainees

who are to qualify as pilots, navigators, and bombardiers.

(1) This includes the fundamentals and application of plane, solid,

and spherical geometry, the use of logarithms, and plane and spherical

trigonometry.

*This manual supersedes TM 1-900, February 26, 1943.
