The Grave Digger's Armored Brigade

How to aim an Ostwind
The Ostwind was a successor to the Flakpanzer IV Mobelwagen (Armed with 37mm Flak 43 L/89) - "interim solution" produced before the introduction of real the Flakpanzer. In July of 1944, prototype of Ostwind (Eastwind) - an air defense armored vehicle build on Panzer IV's proven chassis was produced. Its design was very similar to that of Flakpanzer IV Wirbelwind (Whirlwind) which prototype was build in May of 1944 and was to become the first true Flakpanzer. Both vehicles were build on retired or battle damaged Panzer IV (mainly Ausf F/G) chassis/components returned from the front for major repairs. With regards to Aces High, when attempting to shoot down enemy aircraft with an Ostwind one will find that while in position 2 (Gunners position), the view is obstructed and very limited. This can be overcome with a few simple key strokes.

Flakpanzer IV Ostwind ("Eastwind") 1944

With the screen at normal view the gun sight is hardly practical and tends to be a hindrance more than something serving a functional purpose.	With the screen at full zoom the gun sights cross hairs tend to be obtrusive also. Also it is next to impossible to get a good lead shot in this view.
There is however a suitable medium. If you ever wondered how someone shot you down when you were 1.5 to 2k away from their Ostwind, they probably used the following technique.
1. Go to the Gunner's Position (Position 2).

2. Zoom in all the way while in Position 2.

3. Place your Mouse Cursor on the center of the gun sight cross hair.

4. Now Zoom all the way out to normal view. Then hit the PG UP Key on your keyboard. Your view should now look like this -

5. When engaging an enemy target use the Mouse Cursor as the center of your cross hair and fire away.

If you become proficient at it you eventually may no longer require the mouse cursor and just use the tracers as a targeting reference from this view.
Additional Tips
Some simple points to remember when using an Ostwind are: 1. The maximum firing range of the Ostwind’s 37mm flak cannon is 3.2k. I would recommend not even firing unless the intended target is less than 2k away. 2. The firing spread on the Ostwind’s 37mm flak cannon even when steady does not form a tight group. The shots tend to jump around slightly due to recoil. Slight adjustments may be required when firing. 3. Any aircraft armed with 20mm cannons or better can easily disable the turret. If you can have supplies readily available. 4. If you are at a base, park on a concrete surface so that if bombs are dropped on you, you can land before impact.
