greetings, I am currently totally befuddled on the A-20C bombsight. I have been bombardieirng now for about 3 years so im well versed in heinkle and ju88/betty but this a20 is really annoying me. I have downloaded and use the b-25 charts and will hit within half a block every time but in the a-20 using the same 180IAS 200Tas im going over 2-3 blocks. Tried a manaul drop 38deg and short by a block.
I am under the understanding that there is a knots glitch and have tried both tables with and without. Altitudes is 3100 m or after stabilized at 10000 feet. I am using 60% power supercharger 2, 100%pitch and with flaps maintaining a stable platform at least 2 grid squares out from target. Sight is set and tracking smoothly using data from tables. 180 IAS 200Tas but always missing by up to 2 blocks.

Then tried using tas corrections while on bomb run and still missing by a block or 2. Im not looking for pickle barrel accuracy but is there a tried and true formula for the A-20C?? bombing at 60% seems a bit slow. Tried using the longer tables and 225IAS with corresponding TAS and way off target.

here is the mission:

Try this:

Set the altitude accordingly. Set the speed somewhere in the neighborhood of what it should be for the set altitude.

As you approach the target get your crosshairs on the target and engage the automated site then note the drift of the crosshairs in relation to the target.

If the crosshairs seem to be drifting past the target then increase the bombsight speed until the crosshairs stop moving. Once they stop, disengage the auto bombsight, move the crosshairs back onto the target and re-engage the auto.

If the crosshairs seem to be drifting short of the target then lower the bombsight speed until they stop drifting and repeat the disengage--realign--reengage of the auto bombsight.

Using this method you never need to look at charts or worry about the input data type. I learned this from an old B-29 Bombadier and how he did the Norden.

Yup. And that's the same method I used to create my bombing tables for the PBJ. Works pretty good on the fly...HA! Get it? On the fly!

bah don;t use auto bomb release. Thats for the weak and those who don't like a challenge. Plus i find it to be widly innacurate. Google for a program called bombsight table 2 and use that. Do it manually and you will find you get better results.

Sorry, if you find auto release inaccurate the fault is yours and not the bombsight--it's bang on if you know what you are doing. The method I described works for every bomber in the game without need for any external programs or tables.
