CO 4ib The invention relates to the field of aeronautical engineering and can be used, for example, in helicopter-winding. A device is known for determining the angles of view of a pilot, consisting of a graduated limb with a sighting tube fixed in its diameter and a pointing arrow fixed to the center of the limb. The purpose of the invention is to improve the accuracy of determining viewing angles. For this, the proposed device is a frame made of rods pivotally interconnected and provided with a bracket suspended to it rotating about a vertical axis with vertical and horizontal angles installed on it with a center of lengthening the axes of these limbs on the line of sight, and on the bracket using a bracket fixedly movable mechanical reticle. Figure 1 shows the proposed device; figure 2 - upper part of the device with a mechanical reticle; on fig.Z - section aa in figure 2. The device is a frame made of tubular rods 1, 2 and 3, hinged together. The rod 3 is made of two tubes and can be adjusted to a height. At the end of the lower tube, a vidka is formed for abutment into the floor, equipped with rubber bushings to avoid sliding on the floor. A plumb line 4 is fixed to the rod 2, indicating the deflection angle of the rod on the scale 5. g vertical in the process. The clamping bracket 6, which forms the right angle with the stem 2, is suspended from the clamp 7, which embraces the operator’s head. The bracket has a limb 8 for measuring the angles vertically and a limb 9 for measuring the angles horizontally. Limbs are set in such a way that. the center of intersection of their axes is on the line of sight. A tubular bracket 12 is fixed to the horizontal axis 10 of the bracket by means of a nut 11. The tube 13 telescopically enters the bracket, on which a mechanical reticle is installed, consisting of a ring with crosshair 14 and a front sight 15. The tube 13 is fixed by a locking screw 16. To determine the viewing angles is set as follows. The ends of the rods 3 abut against the floor of the cab, the rods 1 rest on the shoulders of the operator, the rod 2 is installed vertically up the plumb line 4 and the scale-; le 5. i ..., -. . When the operator guides the mechanical viewfinder, which is pre-installed along the cabin sighting line, to arbitrary points lying on the cabin glazing light contour, arrow 17 indicates limb 8 angles of deflection of bracket 12 in a vertical plane, and arrow 18 on limb 9 - movement of the bracket in a horizontal plane . All measurements are carried out directly within the limits of possible rotations of the head of the operator with a fixed case.
