How to release bombs in Ju-88

[xpto]

Thank You.
Another question, the speed on bombsight should be ground speed or indicated air speed?

The difference of about 9° for the gyro compass is the deviation of the magnetic north to the geografic north.
The map is oriented to the geografic north, not the magnetic.
Additional is near the magnetic compass, good visible but not legible in the 109, the deviaton table for that plane, informing about the deviation between the indicated value and the real value for the magnetic compass.
Though the latter is not used ingame afaik.

Map in game Magnetic variation is 10 degrees West

I account for the magnetic declination when navigation planning (9° 16' W changing by 0° 7' E/year, for Calais in August 1940).

But the Ju 88 autopilot is probably bugged, it can't align the directional gyroscope with the autopilot heading (or it aligns but continue turning).

I tried the autopilot Mode 2 on the He-111 H2 and is really better than the course mode, for bombing. I level the plane until reach 300 kms/h to change the autopilot mode.

I'm having trouble when level bombing, introducing the TAS (true/ground air speed) on bombsight after have converted from IAS (indicated air speed) using the manual's table. If I stay at 1000m and use IAS, normally I get a shack. Above 1000m (usually above 2000m) and converting from IAS to TAS, the bombs will fall short for 100m, using a delay of 4/8m. Any thoughts on this distance error?

Edit: At 300km/h, 83m will be passed in 1s. I'll experiment using a pre-determined table height. I'll retire the target height also, when introducing height on the bombsight. The bombsight isn't a computer with radar and/or laser sensors

After align the airplane course with the target, I'll continue adjusting/correcting/aiming the bombsight to a point slighty before the target (for ripple delivery purpose), with automatic bombs delivery: is this the correct method of using the bombsight? Adjusting the bombsight after automation does it introduce some error?

Adjusting the bombsight after automation should not introduce error. Many are having trouble with the automatic release - see this thread.

Thank You.
Converting the TAS to mph and manually adjusting the bombsight after initiate bomb release automation, solved the problem. I hope this feature will be corrected to km/h soon.
