Where is the Flaps Indicator in the P-38?

[6./ZG26_Klaus_Mann]

I'd like to know how many Degrees I'm giving it.

no flaps indicator - only a lever. Quick tap gives combat setting (*50%). After that its just hold to extend further. I guess pilot just did it by timing otherwise.

As far as i can tell, there is just the red-indicator that pops up and down, on the very backside of the left center-wing part.

 

So you can make sure your flaps are fully retracted.

The manual says combat flaps can be deployed up to 250 mph ias, full flaps for landing and no flaps on takeoff. The red indicator on the left wing root by the nacelle indicates full up when not visible.

 

3 settings... up, combat and down. You can leave it in between, but when would you do that?

Some other P-38 models had the same Gear and Flap indication gauge like the P-40 has…..I like that one.

Do you have a reference for that? I have not seen it.

[spitfirejoe]

My reference is that old Training Video, where the Flap-Gear Gauge is shown and explained.

 

At 14:14 you can see it.

I like this Flap and Gear indication Gauge.

 

The Cockpit of our IL-2 P-38 is greatly made, I had the oportunity to climb on top of the wing of the "Skidoo" in Chino last Thursday and checked out the real Cockpit by myself.

Afaik it was present in one of the earlier variants, but then it got deleted.

I have seen two types but this version does not have either.  The cockpit panel is from a P38H and the early Js also had one but then they dropped it and just used the indicator on the wing.  I am not sure where the instrument is from but it claims to be from Dick Bongs own aircraft.

I remember seeing it now, thanks. I watched it again. Gotta love the cartoons. ?

Interesting movie  I like these combined gear/flap gauges too, but can imagine they were complex to produce, install and maintain. Did later P-40's keep them, I wonder?

 

I noticed around the 10:50 point in the movie that inverted flight was not recommended for more than 10 seconds and he said that engine bearing oil starvation due to loss of oil pressure. This critical point was reinforced around the 26:32 mark.

 

I never knew this and I'm interested to know more. Ie., did this affect later P-38 models like the P-38J-25 that we now have in BOX? Was it an issue with other Allison engined aircraft, of that time or later?

[spitfirejoe]

I also noticed the 10 second Limit for inverted flight, the Allison V-1710 engine has a dry sump lubrication system and I always thought that prevents problems for inverted flight maneuvers.

It affects most, if not all planes of that era. You'll find 10-sec limitation in P-51 manual as well, for example. Dry sump might be suitable for much longer inverted flight, but the rest of the whole oil system usually isn't :D. Not that the feature is required or designed-in anyway - in normal combat situations pilots practically never needed 10+ sec negative G maneuvers.

 

No idea how this sim's systems modelling tackles this issue, though (if it does).

Yep, dry sump was pretty much my pre-sumption too

Indeed, 10 seconds is a very long time in combat. Another good reason to avoid getting into an inverted flat spin
