DCS P-51D QUESTIONS


Peyoteros

Recommended Posts

I recall reading that the mags switch actually turns a boost on the mags, and that they actually work any time the engine is turning over. In other words, with a little luck, and maybe coaxing, you could start the engine without mags turned on.

 

Beyond that, I wouldn't take sputtering, or any other sounds the engine makes outside normal SOP too seriously. Much of the way it works is programmed for you to follow the manual, and if you don't it is more coincidence than plan if it works at all.

 

For example, leaving the mags off, turn the engine over for 5 seconds. The propeller turns like the engine had zero compression spinning at like 200 - 400 RPM simply off the starter motor. If you've ever watched a startups video of an actual P-51 where it takes a few revolutions for it to fire, the propeller should NEVER turn faster than that until starting because the compression is slowing it down that much. You won't see that here, sadly.

it makes sense with the B-29s with the beacon, kind of the precursor to Tacan A/A mode to guide the Fighters. :thumbup:

Yes you are right, even Ucle Dog was much simpler, it only gave tone to pilot`s headphones. It did not give to pilot any information about real course (means in degrees).

technicians from 506th FG (458th FS) made pretty "full mission simulator" for pilot familiarization with new equipment :smartass:

I hope, one day ED give us proper radio communication and some from radio navigation for WWII planes :)

Yup, booster coil. Pretty cool stuff. Engine will run with mags off, as long as the starter switch is held. The engine timing from the booster coil is retarded so you'll have low power....and probably kill the starter pretty quickly if you tried it on a real engine.

 

The booster coil supplies spark during cranking to get the engine started. The RPM of the engine during cranking is too low for the mags to generate a spark so the booster coil provides the initial spark needed for ignition. The booster coil is powered from the battery, thru the starter switch. The distributor rotor has two "fingers", the trailing finger is connected to the booster coil. It's behind the primary finger so the spark is retarded, I can't find this spec, but I'd guess it's at or very near TDC.

 

I'd really like to see a pic of a distributor rotor with this arrangement, if anyone has one.

 

Here's a great little article that explains how a booster coil works.

Hi,

every fighter units involved in VLR had assigned navigation B-29. They met them after take off from Iwo, just North of island and followed them until they joined the bomber formation which they should cover over Japan. This meeting with bomber formation happened just few miles from Japan shore.

 

Way home started at Rally Point, south of Tokyo Bay where all fighters (and lost, damaged bombers) flew first to met others and put together before flight home. Fighters met their navigation B-29s here. From this point they started flight home.

Navigation B-29s circling above Rally Point had own fighter escort and they waited there as long as possible.

Fighters pilots in trouble just asked any B-29 for help (and all helped) with travel home and they led them home in that case.

 

Fighter pilots did not always find any B-29 for some reason and then they had to flight home alone, and they did it! 660 miles from Tokyo to Iwo only with magnetic compass above endless sea!

 

Rules was when fuselage tank was empty, they immediately headed to Rally Point and search for way home to Iwo. Yes, they fought against IJA a IJN with fuel in fuselage tank!

 

Several destroyers and submarines were along route, plus P-61 from Iwo helped during return to find the last part of their way.

 

After UncleDog was introduced several B-29 was equipped with beacon and one was installed at top of Suribatchi on Iwo. But it was useful only with range up to 150 miles.

This was only radio aid used for navigation.

 

The most dangerous enemy was weather, it caused the majority of all loses, include the 1 June 1945 Black Friday disaster.

 

Navigation chart was generally simply, North to target and South to home...

Noob question......

How do you know what angle you are climbing or diving at?

Climb rate indicator, artificial horizon, look out over your wing tip.

Hey Captain,

I really did not make myself very clear.....sorry.

1. I got the look out over the wing tip

2. How does the climb indicator tell me what angle my climb or dive is at?

3. How do I use the artificial horizon? Mainly, I can't seem to find in the manual how to properly use this indicator. For instance, what the tick marks indicate as far as degrees of bank and are there any tick marks for climb or dive angle? What degrees are these tick marks?

 

The main reason for the question is I am fairly new at flying and am trying to learn how to bomb and use rockets in the P51. When diving, I don't know what a 15 degree or a 30 degree dive should look like and I want to look at an instrument to guide me to those degrees. I assume after awhile I will just know by looking out the window but currently I don't have picture in my mind what those angles look like.

 

thanks

Even Mustang pilots during WWII did not know exactly this value.

You do not have any AoA indicator in these planes.

It was reason why they used several aids like painted lines or marks on canopy or wings.

 

It is not answer to your question, but ..

 

You can at least use "Info Bar" to gain reference where are AoA indicated and then "remember" approximate planes position against horizont line.

 

But, finaly your ability to destroy target will always depend on your actual speed, vertical speed, altitude and training not on some exact "value".

These few things may help,

in DCS manual is written about Gyro Horizon Indicator that "The horizon bar will indicate pitch up to 60°.." So, when horizon bar touches top of instrument, you are in 60° dive. pic.1

 

Not from manual but, when horizon bar touches marks for 30° bank from painted bank scale, you are in 30°dive. pic.2

 

For both you have to have precisely set horizont bar...

 

And when you are in 15°dive, outside horizon line nearly touches top of your bulletproof windshield. pic.3

P-51 Engine Quits

 

I've twice tried to fly my first campaign mission in the P-51 but I can't get more than halfway across the Channel before my engine seizes. I'm not running it out of fuel -- it is on a full tank and it stops with a bang and does not windmill. Clear weather, trying to climb between 170-200 mph. I was running at max continuous 2700rpm/45inches trying unsuccessfully to keep up with the lead 4-ship and I noticed the coolant and oil temps getting high. I thought this was lame, but I pulled it back to max cruise power top of the green rpm/mp and the temps normalized. These temps stayed good, but after a while I noticed the carb air temp was below the green (in ram air, supercharger auto) just before it went bang on me. Altitude was fairly high at this point so the air was cold but I never went through a cloud. Can anyone tell me what I'm missing? Thanks.

Coolant and oil radiator doors in auto?

 

Are you warming the engine up properly? (Idle at about 1200-1300 RPM until the oil temperature reaches 40°C and the oil pressure is steady)

1.Good take off conditions is more then 40 C oil temp and more then 60 C coolant temp.

2. Take off always at 3000 rpm at least 50" 55" will be better.

3.Just before t/o open coolant radiator fully, coolant door actuator cant keep up with rising temp it will prevent overheating at t/o especially in hot weather.

4. Make sure that you have both magnetos on, mixture is at Run position not emergency rich this is very important.

5. Once you lift off you can switch radiator to auto mode, oil radiator on auto all the time.

6. When you change power settings always remember that high MP and low rpm will damage your engine, so when reducing power MP comes first rpm goes down later, if you increasing power rpm comes first MP later.

7. Avoid idling below 1000 rpm on the ground.

Thanks much for the reply. I have done all that except opening the radiator manually, so I will try it.

P51 Mustang Buying Question

 

In my list of model aircraft I have install one is the P51D Mustang. When I look at any of the campaigns available for this aircraft while in DCS it shows "DCS: P-51D Mustang" in red like I need to buy the same plain I already have installed.

 

Can someone tell me why?

I can't believe that you are seriously asking such a rediculous question. How can you buy an airplane that you already have purchased. When you see the red text for the campaigns, it is simply warning people that they need to own the P-51 before they buy that campaign. Just to make sure that someone doesn't purchase the campaign thinking that they get the Mustang with it.

I cant seem to find any good information on formation flying with bombers on escorts. Ive messed around with trying to get some speed control but im struggling with keeping stable with B-17s without shifting left and right heavily. Does anyone know of any good resources or tutorials? Im new to warbirds in DCS so any help is appreciated.

Thanks!
