Level bombing help
« on: January 20, 2010, 09:56:06 AM »
Ive noticed that the bombsights now do not show your speed and ive been needing help with level bombing,
Usually either my speed is 20MPH up or 20MPH down and my bombs fly around 500 100FT from where im aiming

im gonna need some help because not blowing things up is getting to me   :D

Open the E6B on your clipboard and drag it into a place that allows you to see your speed even when zoomed fully in while being in bombsight:

Watch the climb on e6b too. Just as important for precision bombing. Your can tell right away if your accelerating/decelerating because you have a + or - climb. Watch the speed alone and you have to wait and see if it changes. When climb is at 0, you're golden.
 If you havent done this try Leveling out and settling at constant speed at 95% throttle. Time your calibration to finish with 20 sec till drop. After calibration immediately fine tune your throttle if there is any speed discrepency then fine tune your alignment on your target. Guaranteed accuracy! I only use salvo 1 and 1k lbs bombs with a set of bombers when dropping hangers.

Just to expand a little on what Lushe and Stran said -- after calibration, compare the bombsite calibration speed (in the upper left corner of the screen) with the ground speed shown on the E6B.  (NOTE: Since we do not have wind, ground speed will be the same as true air speed.)  If the deference in bomb calibration speed and E6B speed is off by more than 5 mph, either recalibrate or adjust throttle so the E6B ground speed is within 1 or 2 mph of the bomb calibration speed -- be carful not to over correct and chase the correct speed.  If there is not enough time before the drop to get this done, you can adjust your aim point.  If ground speed is greater then calibration, bombs are going to hit past your aim point at release so you will want to release before the cross hairs reach the target.  (NOTE: The higher your altitude, the greater the impact a speed error will have on bomb accuracy.)   At 15,000 feet above ground level, a 5 mph difference in speeds will result in a 224 foot error.  This is about the width of a fighter hanger.  Naturally, if ground speed is less then calibration, drop bombs after the cross hairs pass the target.

Minor tip, instead of trying to juggle throttle, try hitting the keypad - + keys to change  RPM instead of throttle. Easier to make small changes, and less likely to bump it screwing up your approach.

Also design your flight plan so that your last turn is as far from the target as possible.
This gives you time to stabilize your speed. Open doors early, use either external view, or nose gunner view to line up the plane so that it will overfly the center of the target. I do this before I calibrate, just as the target comes into view.

Then calibrate, note calibrated speed, exit calibration, pull up E6b, make the calibrated speed my ground speed.
Then zoom in to target and drop.

It will seem to happen real fast at first, but if your speed is constant going in, it won't take a long calibration.
And it won't take much to bring ground speed to calibrated speed.

A very good one.

I always try not to fiddle with my throttle again after initial calibration, until I have dropped all bombs and am otw back home. I adjust differences in speed by using throttle and the bomb bay door (yes, you read that right). When I really get considerably slower after a hard turn ( I try to avoid that), I even give up some alt to get back to speed ("recalibrating" alt only takes a split second, entering & leaving calibration mode without hitting Y is all you need). I rarely calibrate my bombsight more than once during a sortie.

I like to calibrate to 1-2 mph faster than my drop speed to account for course corrections on the final approach.  If I'm perfectly alligned then I'll use left and right rudder trim to "walk" my plane to the target burning off that extra speed.
I edit a lot of my posts.  Get used to it.

I like to calibrate at the same time im adjusting throttle. If its done right, under 15seconds you can have perfect calibration, steady speed/attitude along with correct alignment to target.

One thing we've noticed, when your lining up, sometimes people are in zoom when they calibrate. I used to do this because I would always calibrate at the last second, and I would be zoomed in to line up. Whenever we did that tho, we were always falling short, I'd drop late to compensate. Everything would be golden, speed, alt, whole nine yards, but still we would drop short. Moral of story, don't calibrate zoomed in. Anyone got theories on why this is?
