When you are at least 1 sectre away from yer target, cut your throttle. Id say about 75% on b17's and lancs. Open yer bomb doors and use your nose gun position to set your course for the target. make sure you click on the target on the map to set the alt. As you approach 1/2 sectr away, you should be at the speed of the drop. Tis is important because if you calibrate at a different speed, the bombs will fall hundreds of yards away.
Now, get into calibration mode and pick a spot aabout halfway inbetween your planes and the target.
Myself, I choose not to zoom in too much. Mybe just a tad.
keep the crosshairs on the spot for as long as possible, but do not allow the crosshairs to pass under the aircraft.
Release the calibration button without moving the joystick . Now you are ready to drop.
It takes practice and patience. Dedicate 1 wqhole camp to buff driving and you will have it down pat.
Hints. Claibrate as close to the target as possible, but leave yourself enuff room to calibrate again incase you screww up the first one. I find this extrememly helpful.
Write off 30% of the bombs as waste material, you want to drop 2 salvo's infront of the target and 2 salvo's behind the target, just in case of 'long' or 'short' calibration. Dont try to pinpoint bomb, you will miss by a few yards and waste the entire load.
The airbases are poor for AH bombers since the blast radius is very small and the targets are spread out. I have killed all 4 bomber hangars at a medium airbase before, but they come right back up. In fact, fighters from the ded hangars first pass were upping to kill me as I was omw home. This makes me mad and I no longer waste my time with FH's
Towns, an the other hand, are a joy to kill with bombers. thats what ww2 buffs were built for. Killin towns and cities and factories,.
