T. O. 07-1-1 , General-aircraft camouflage, markings and insignia, December 26,1943
4. STANDARD INSIGNIA.
$1. Standard insignia will be placed on all Army Air Forces aircraft. It will be applied so that in normal flight attitude at the airplane, the top star point of the insignia points upward on fuselage surfaces and forward on wing surfaces. Decalcomanias may be used when available.
(I) The standard insignia retains the five-point white star within the blue circle (as formerly). Standard sizes will have diameters of the basic blue circle in multiples of 5 inches, as 20, 25, 30, 35, etc.
(2) The straight line formed on the top edges of the two-star points that are located to the left and right of the
upper star point will be extended outward from the blue circle a distance equal to one radius (one-half of the diameter) of the circle. Draw lines at right angles to this line at each end extending downward for a distance equal to one half the radius of the circle. Draw horizontal lines parallel to the first line from the ends of the two vertical lines until they intersect the circle. The area thus created will be painted white.
(3) Using a width one-eighth the radius of the circle, place a border of insignia blue around the entire design thus formed.
b. For wing insignia, the diameter of the basic blue circle will be the standard size which is nearest to, but does not exceed 75 percent of the distance between the leading edge of the wing and the aileron cutout at the point of application. It should not be greater than 60 nor less than 30 inches in diameter. The insignia specified herein will be placed on the top surface of the left wing and on the lower surface of the right wing with the center of the insignia inboard from each wing tip one-third of the distance from the wing tip to the fuselage, and with the blue border tangent to (touching) the aileron cut-out. The insignia may be moved in a minimum distance necessary where space is not available for the minimum size specified. On biplanes, insignia will be applied only to the upper left wing and lower right wing.
c. For fuselage insignia, the diameter of the insignia will be standard size which is nearest to, but not greater than, 75 percent of height of fuselage at the point of application. The diameter of the basic blue circle should be not less than 20 inches, or greater than 50 inches. These will be placed and maintained on each side of the fuselage near midway between the trailing edge of the wing and leading edge of the horizontal stabilizer, but may be moved to the rear (or forward) of the midpoint to avoid turrets or other plastic material. The insignia may extend over doors and emergency exits, but shall not extend over windows or
openings which would change the insignia pattern. If the fuselage section, as described herein, is not large enough to accommo date the minimum size specified, the fuselage insignia may be placed on such other parts of the fuselage as will permit its being readily seen from the side. On aircraft assigned to AAF Training Command, if insufficient space is available for both insignia and Field identifying numerals, the fuselage insignia may be omitted.
T. O. 07-1-1, instructions for removal of camouflage, at the discretion of the commanders concerned, April 25, 1944.
4. STANDARD INSIGNIA.
a.GENERAL.
(1) Standard insignia will be placed on all Army Air Forces aircraft. It will be applied so that in normal flight attitude of the airplane, the top star point of the insignia points upward on fuselage surfaces and forward on wing surfaces. Decalcomanias may be used when available. Masking paste, Specification No. 14127, may be used in lieu of masking tape if paint is used.
(2) The standard insignia retains the five-point white star within the blue circle (as formerly). Standard sizes will have diameters
of the basic blue circle in multiples of 5 inches, as 20, 25, 30, 35, etc.
(3) The straight line formed on the top edges of the two-star points that are located to the left and right of the upper star point will be extended outward from the blue circle a distance equal to one half the radius of the circle (Note: this is an error-see T.O. 07-1-1B, dated May 29, 1944). Draw horizontal lines parallel to the first line from the ends of the two vertical lines until they intersect the circle. The area thus created will be painted white.
(4) Using a width one-eighth the radius of the circle, place a border of insignia blue around the entire design thus formed.
b. WING INSIGNIA. - The diameter of the basic blue circle will be the standard size which is nearest to, but does not exceed 75 percent of the distance between the leading edge of the wing and the aileron cutout at the point of application. It should not be greater than 60 nor less than 30 inches in diameter. The insignia specified herein will be placed on the top surface of the left wing and on the lower surface of the right wing with the center of the insignia inboard from each wing tip one-third of the distance from the wing tip to the fuselage, and with the blue border tangent to (touching) the aileron cut-out. The insignia may be moved in a minimum distance necessary where space is not available for the minimum size specified. On biplanes, insignia will be applied only to the upper left wing and lower right wing.
c. FUSELAGE INSIGNIA. - The diameter of the insignia will be standard size which is nearest to, but not greater than, 75 percent of height of fuselage at the point of application. The diameter of the basic blue circle should be not less than 20 inches, or greater than 50 inches. These will be placed and maintained on each side of the fuselage near midway between the trailing edge of the wing and leading edge of the horizontal stabilizer, but may be moved to the rear (or forward) of the midpoint to avoid turrets or other plastic material. The insignia may extend over doors and emergency exits, but shall not extend over windows or openings which would change the insignia pattern. If the fuselage section, as described herein, is not large enough to accommodate the minimum size specified, the fuselage insignia may be placed on such other parts of the fuselage as will permit its being readily seen from the side. On aircraft assigned to AAFTraining Command, if insufficient space is available for both insignia and Field identifying numerals, the fuselage insignia may be omitted.
