Level bombing help

[Nicob]

Already read almost every guide out there, i am having problems with level bombing. My bombs always fall long of target (by 20/70 mts) I take a long time configuring all the input data right, set the altimeter to nearest friendly airfield and no luck idk what i am doing wrong

anyone has any idea?

Keep in mind, the point of aim with the bombsight is the start of the bomb train and you have to subtract the height of the land from the altitude you set.

Oh i drop the bomb one by one manually, do i have to press the drop key after the target is on the crosshair? 

 

I thought the "set altimeter on the nearest army" taked care of the altitude difference, what is a good solution? subtract 100 or 200 mts?

Supposing everything else is set correctly, you are higher above the ground than what you set in the bombsight, if your bombs fall long. Use the altitude you read from the pilots gauge, after setting it to nearest friendly field, not the one you read in the bomb sight. Just a guess. Wind is dialed in correctly?

Dude, you are gonna love the ripple and interval feature the more you get used to bombing!

 

Like Nocke said, set altimeter to nearest airfield is usually a good idea as long as your target isnt in the mountains.

Edit: Just keep in mind, the bombsigts altimeter shows sea level regardless of setting, you have to use the cockpit gauge.

Blanked-ly subtracting 100-200 meters has served me well over Stalingrad.

What alt are you bombing from?  If you haven't already, go into Quick Mission, spawn yourself at 3k on NORMAL difficulty settings.  This enables the HUD to display your exact alt above current area, input that alt, set up your sights ofc, and then see where you go from there.  It also helps to have the bomb assists aimer enabled so you can see if you are setting your sights off.

 

The higher the less accurate, but also the safer you are from AAA.

 

Based off my experience, small bombs will generally have greater spread than say a 1800kg bomb but this may also just be that on smaller bombs its easier to identify where your bombs landed from 5k.

Just did a test with a He 111/6 on the Kuban map. I took 16 50kg bombs and subsequently bombed points at different ground levels i.e. on hills and valleys. When I dialed in the values given in the bomb sight's upper left I got the highest precision.

My conclusion from this is that the true altitude conversion and also the true airspeed conversion is not shown on the bombsights dials, but nevertheless is actually done in the background.

 

This of course is very confusing and does not make sence since one expects the bombardier to feed in the already converted values. In respect to the wind calculation it is consistent though.

 

"Set altimeter to nearest friendly airfield" is for landing purposes only.

For setting up the bombsight just use the altitude above sea level and indicated airspeed shown on the left hand side of the bombsight GUI.

I disagree.

Here's a video I did some time ago. For unknown reason it shows in shitty quality now, but I believe it still shows my point.

I also just did some more tests in the Kuban mountains, with higher terrain, which proove that the bombsight altimeter does not do any conversion, but I am now too lazy to make another video from that.

Tested with the Pe2 100kg and 250kg with height above sea level as shown in bombsight. 100kg is dead on aiming point while 250s fall long. Aiming with 10° mark just above the central mark instead of central mark 250s hit.

I still have to test with "nearest airfield". Will report later. If altitude is actual lower than dialed in the bombsight should bombs not fall short instead of long?

@Nocke BTW we are flying tonight.

[Nocke]

no, if altitude is lower than dialed in they definitely fall long, maybe I make a drawing later. But you also see that clearly if you dial in grossly wrong values.

[Nocke]

Coconut convinced me some time ago why they fall long if you dial in a too high altitude, using this artistic scheme made by him:

I went to the mountains and it seems you are right.
