Can you help me with proper aircraft operations for my next vid? Bf-109 manual pitch

[Freycinet]

Hi all,

The biggest difficulty of making tutorial vids like the Spitfire Mk. I movie I just did is to get a list of the correct aircraft operations. A script for the videos, in short.

I got lots of help from Flea's very comprehensive pdf, and based on that one I made my own "quick guide" (see below).

What I need is a SIMILAR check list for the Bf-109E (manual prop pitch), because that is the one that will star in my next video. Do you think you can help me out? Not necessarily with the whole thing, but maybe just with bits and pieces of the complete list.

Importantly, I don't want just "educated guesses". I'd like it to be the proper historical procedure as amended for Il-2 CoD. What do I mean by that? Well, for instance in the case of the Spit it is not necessary to flick the magnetos on before ignition. It is done automatically in this sim when you press ignition, which I think is a good compromise between realism and playability (Basically, pressing "i" is short for "throwing the magneto switches and then engaging the starter".

Many arcane and superfluous steps have been omitted from the sim, and I'd like to weed them out of the "quick guide" too.

So, do you think you can help me with something like this, but for the 109?:

SPITFIRE Mk. I

Start-up:
Fuel cock Open
Mixture lever Rich
Throttle Idle
Prop pitch Fine
Radiator Fully open

Take-off:
RPM ~2800
Boost Not above +6.25
Take-off +85 mph
Climb speed 160 mph

Landing:
Mixture lever Rich
Prop pitch Fine
Gear down Below 160 mph
Flaps down Below 140 mph
Landing speed 90 mph

- What aditionally would be really great is to also have the explanation for (for instance) the dials and why a particular ATA boost level is correct. In the Bf-110 for example, the ATA has "d", "15" and "30" on the dial, meaning the boost that is acceptable for (infinite) "duration", and for 15 and for 30 minutes. It is stuff like that I need to explain in the videos.

Also settings for climb and for cruise are needed, as well as the spin recovery drill.

For the next video I would like to also include trimming the plane, which is missing from the Spittie vid, but which I should have included.

Anyway, I thank you for your contributions and I hope we can nail this!

That is easy:

Take off and climb

1. Brandhahn(Fuel cock) on

2 Magnetos to M1+M2 (happens automatically)

2 Throttle stays at idle

3 Inertia starter on

4 keep engine running below 1000 rpm for warm up (actually not necessary with actual patch)

5 set prop pitch to 12:00 o'clock

6 oil and water radiator closed for faster warm up

7 on reaching 40°C oil - temp the water is about 70°C open oil rad to 50% and water rad full

8 set flaps to about 15° (Indicator between 1 and 2)

9 trim slightly tail heavy

10 gradually increase throttle to max. (1.32 ata), when in fully loaded FB use emergency power.

11 dont force the plane to fly, keep a slight nose up attitude until the plane lifts itself at about 170 - 190 km/h

12 retract gear, when retracted gear handle to neutral

13 retract flaps

14 reduce power to about 1,25 ata, set rpm with proppitch to 2350 rpm(11:30 - 11:45)

15 adjust trim for a speed about 250 - 270 km/h

16 with increasing altitude use proppitch to keep the rpm's at 2350.

Cruising:

prop pitch at 9:30, 1,0 ata speed is about 300 km/h, CLOSE OIL COOLER almost completely rpm's will be about 1700

Landing:

During approach set proppitch to 12:00, throttle back to avoid overspeeding the engine, thereby reducing speed.

On reaching 250 km/h flaps and gear can be extended.

With trim set a approach speed of 170 km/h

HEIGHT=THROTTLE SPEED=ELEVATOR

on crossing threshhold, at about 5 m height, cut power and flare

touching down with about 140 - 150 km/h with a three pointer

careful with the brakes

Turn the engine off with the Brandhahn

Turn magnetos off

WAUW, fantastic postings guys. I'll make comments and questions on them later, just wanted to post to acknowledge your work! There is a lot to work with, together with Flea's pdf.

[Freycinet]

Next weekend I'll try to check out your procedures together with what I got from Flea's pdf, and then they hopefully coincide... And hopefully they do not stray away from the official historical manuals! That is the crucial point for me, because rather than just "what works in the sim", I want my tutorial to reflect the correct historical procedures (as amended and simplified in the sim).

Also, in addition to what you so helpfully posted I also need the "why" of the different steps. So I can string them together, according to the internal operational logic of the plane.

[ATAG_Doc]

Very good information guys. Really good to see all this put together in here for all to see.

Posted highlights from Mr.X 109 video here http://forum.1cpublishing.eu/showpos...7&postcount=23 and on SimHQ.

Hope it helps.

Thanks Ataros, very helpful.
