BZG-2 operation: • Establish course to target. Pilot can use the old compass/course heading plus & minus keys to set needed course to the Patin compass and “kurskreisel”. When course autopilot is engaged, the plane will turn to selected course and maintain it. This is also very convenient for navigation. • Look through the bombsight optics as bombardier. Bombardier can use the new bombsight keys “course left” and “course right” keys to make very small and accurate corrections to plane's course. “Course ahead” key is just for convenience and it will set the Patin/kurskreisel course immediately to current heading. It should be only used before engaging the course autopilot. • Eliminate wind drift with bomb sight drift keys if needed. There should be no sideways movement. • Keep steady speed and take following measurement to find correct drop angle. • Adjust bombsight elevation angle so that the dual triangle mark (1) points to correct alt reading (values at the inner ring). 30 means 3000 meters. In the screenshot below the elevation angle is set to 3000m. • Wait until a suitable fixed landmark appears at the reticle. This landmark cannot be your actual target because this procedure needs to be made well before you reach your actual target. Landmark should be selected from near sea level to have most precise measurement. For example shorelines are good landmarks. • When the center of crosshair drifts over usable landmark, turn on the bombsight automation (with the old key you should have already mapped). • When the bombsight automation is turned on, you should see the hollow triangle (4) moving clockwise. It shows the drop angle you need to use and it will keep on moving until the bombsight automation is turned off. • Start reducing the elevation angle so that the dual triangle mark (1) moves clockwise. Reduce the angle until it reaches the fixed black triangle (2) at the end of the altitude scale. Alternatively this whole process can be made at the shorter secondary scale (at 6 o'clock of the reticle) using larger elevation angles. In this case you need to reduce the elevation angle until the mark (1) meets the fixed black triangle (3). • When you have reduced the elevation angle so that triangle mark (1) is at the correct end marker (2) or (3), you just need to wait until the very same landmark you selected is under and center of the crosshair again. When this happens, turn off the bombsight automation to stop the drop angle marker (4) movement. • Now you have established the correct drop angle for your current speed & alt. Adjust the elevation angle so that markers (1) and (4) meet and your bombsight is set to the correct drop angle. • Drop bombs manually when the target appears at the center of the crosshair. |
