View Full Version : Is there a trick to using the Level Stabilizer?

11-17-2004, 06:41 AM
Hi All,

I've been practicing using the Bombsight lately in the B-25. I'm using the level stabilizer on the bomb run, setting my speed and altitude and then setting the bobmsight on the target. My problem is that the level stabilizer doesn't do a very good job at keeping it's altitude. I notice the altitude keeps decreasing with the use of the level stabilizer as your on the bomb run, making it impossible to accurately set the altitude and hit the target. Is there a workaroud to this or do I just need to keep my spped and altitude manually?

Thanks in advance

When I hit the level stabilizer I usually drop to combat flaps as well and end up getting the plane level. You may also still have to make some fine adjustments with elevator trim.

It's a little bit of an art but just keep practicing it.

Ahh, ok. Makes sense. So the level stabilizer is not so much of an autopilot, but more like an aid in keeping a level altitude.

I find that raising and lowering combat flaps i can keep my altitude within a reasonable range to allow accurate bombing.

Hi guys.. The level Stab works more as a wing leveler than anything else, because of its inability to maintain altitude...

As others my workaround is to use it in conjuction with combat flaps, It is pretty consistent and these numbers may help you...

3000 lb loadout and 50% fuel
Combat flaps + level stab
73% throttle will stabilise at 290kmh at 3000m
altitude change is + or - 10m over a 30 minute span.

Hope it helps

I've used the flaps with the B-25 but right after I engage the bombsight automation the flaps will straighten out and cause the plane to continue its shallow dive, which messes up my bomb run. I've noticed it does that once in a while but not all the time.

The flaps and the toggle bombsight automation aren't using the same keys, so I was careful about that. Any of you seeing the problem?

Snazzy sig, RedSpar.

I loadout full fuel and a 3,000lb bombload (prefer the 6 500lb). Run it to 5000 meters or so set level stabilizer, then set combat flaps then trim her all the way up, till she starts climbing, then i use the throttle to meter my altitude, usuallly 80% or so will keep you level (at 100% prop pitch) , and give you a speed of roughly 270 kmph.

the level stabalizer works great in He111

But in B25 its a bug imo & needs to be fixed

If you maintain a higher speed, your altitude will stabilize sooner.

In the B-25 I usually floor it, then dive a little, to get speed up to about 350kmh.

Then engage the stab and pull trim all the way back. It will only take a few seconds for the plane to stabilize, then start climbing a bit. Then I can trim it level.

If you go below 300km/h, it will take much longer.
