To the point: Is anyone still using this aircraft? And does anyone have a REAL paint they would like to see. I'm open to offers. Just don't ask for personal registrations!

Fed up with the magneto bar not functioning properly ? Like, you can't even switch off all the magnetos at once...

Proceed as follows :

1/ Please add the following line in the panel.cfg file for the C421, in the [VCockpit04] section

gaugexx=GAUGE_C421!Gauge_UPDATE_DIG_GP,            0,  0, 1,  1

where you will replace xx by the number immediately after the last gauge of the section (most probably xx=06)

If you are not sure of what you are doing, please keep a backup of your panel.cfg before making any change here.

2/ create a GAUGE_C421 folder in the panel folder for the C421

3/ create a GAUGE_UPDATE_DIG_GP.xml file in that new folder and edit it with Notepad

4/ insert following code in the newly created xml file :

<?xml version="1.0" encoding="UTF-8"?>

 5/ save

6/ reload your aircraft in the sim

7/ enjoy !

If that does not work for you or if I speak Chinese, let me know in a message and I'll send you the files.

Have fun and contribute to the community !

Pros:

• The sound is amazing and IMO one of the best out of the box. Engine start and panning around the Airplane is such a soundpleasure.
   
• I am not a real pilot but with the "advanced physics" by Andi it brings so much fun flying the Golden Eagle.
   
• Like i sad, good looking with great system variety.
   
• They paid attation to details (taxi light pans, working cabin signs and clock, etc)

Contras:

• No user manual for all the switches, gauges and systems! Even freeware-airplans have a manual!
   
• VC panel lights are not seperatly switchable. To read the gauges at night you have to light up the hole cabin!
  That bothers me most.
   

Issues:

• The "AL421fuel_pump.wav" is missing in the sound-folder so i copied a file from one of my other airplanes into the folder.
   
• The "cold and dark" and "ready for taxi" start option lets miss many settings. The "StartWindowsAircraft.xml" file has so many wrong and useless entries (like PA44 or Malibu) so i corrected it to make it a little better functioning.
   
• The gauge "M877 Chronometer" is poorly modeled, so i corrected the look and made "LT" 24hrs and "FT" starting with 00:00 (instead of lokal time !!!). In this context i also made the cabin clock 24hrs.
   
• The gauge "Shadin Avionics DIGIFLO" is poorly modeled and the switches and mode-selections are messed up. I corrected it for myselfe so it works now (not totally realistic but) better.
  BTW i can not understand the developers! If they coded it one time correctly, they can use the gauge in all there planes and they never have to worry about it again.
   
• With Bert's solution in his first post (Title "Yaw Damper") the yaw-damper-switch is now working.
   
• I'm not sure if the weather-radar works properly. I had in rainy-conditions no radar reflection and in best-weather-conditions i had one! (under observation 😉
   
• The gauge-reflections on the VC right hand side are a little heavy so i customized a few textures to my liking.

My conclusion:
Not perfect but one of the best plane implementation from Alabeo/Carenado by now IMHO. I do not regret the purchase in any way and can really recommend this plane. One little step to get closer to A2A or Milviz...

Best regards
Raller

1. Why I developed the advanced physics version

I was asked via this forum, via PMs and also by e-mails to provide a modified version of the Alabeo C421C which can be used for serious multi-engine training. It should have accurate type specific performance for both AEO (all engine operative) and OEI (one engine inoperative), the latter for either a windmilling prop at various speeds and for a feathered engine. Feathering should work as realistic as possible.

Thus, I developed an advanced physics version of the Alabeo C421C. It shows realistic physics for negative thrust (prop drives engine). This is necessary for OEI training and more realistic idle power simulation.

2. Where to download

The modifications to the “c421.air” and “aircraft.cfg” files,
aircraft data, equipment list, checklist and other documents for N100L,
as well as some images of C421C, registration N100L, can be found here:

https://www.dropbox.com/sh/9fbvh4w0lpkv3zk/AACFtH_FhttbtkGkuZB8iTB-a?dl=0

Unfortunately, due to copyrights, I can’t upload the full files and can’t provide the AFM and other copyright protected documents.

3. How to install

To update “c421.air”:
- Copy the original Alabeo C421 to another aircraft folder, e.g. “C421C advanced physics”.
- Use AirEd (freeware) and open the original “c421.air”.
   Open AirEd a second time and open “modifications advanced physics c421.air”.
   Copy the modified tables 511 and 512 to the original .air file
   (right click in modification file -> copy -> right click on original file -> replace from clipboard)

To update “aircraft.cfg”:
Just copy the modifications to the corresponding position in the original file.

4. Legend of modifications

Modifications in aircraft.cfg:
- Basic Empty Mass (actual mass for N100L 5,154 lbs inserted; most C421C are more heavy, ours is on diet)
- correct basic data for engines + props
- engine friction included (necessary for all negative thrust scenarios)
- flaps lift + drag scalar adjusted (split flaps)
- 2 vacuum pumps
- VMO = 151 KIAS; VNE= 240 KIAS
- cabin: max. differential pressure: 5.0 psi

Modifications in c421.air:
- implemented negative thrust scenarios in prop thrust and efficiency curves (tables 511 + 512); adjusted thrust curves for high TAS at high ALT

5. Side effects of modifications:

- more realistic engine starting:
starting the engine needs the throttle to be 2 cm above idle (see checklist) for the first 15 seconds

- if you start the engine and don’t retard the prop to medium RPMs immediately, you will overstress engine and prop. So be careful when doing an air start, you might lose the prop and the aircraft. (In the real aircraft, these effects are less severe, but you have to avoid high RPMs until the engine is warmed up and have to avoid rapid change of RPM.)

6. Additional Notes:

- Basic aircraft data as published by the manufacturer, like range and service ceilings, especially OEI, are based on MTOM.

- The use of high payloads close to MTOM and higher ambient temperatures are making for a more challenging OEI training.

- In the sim, climb power is too low compared to full power (about 65 % instead of 75 %). I have to find a way to adjust that. 

- I have buttons for engine failure under the mixture (see images)

- Seat Position is, like in many Aircraft, higher than as per Default by the sim. For the C421C and me being 5 ft 7 in, that's about 7 clicks arrow up.

Stay sharp!
Enjoy the training!

Best regards,

Andi

Don't know if I have corrupted installation or not. 

What trim setting do some of you use and at what speed do you rotate the 421.

Now she does not like to bleed off speed. Approaches are very tricky.

That FDE is optimized for Prepar3d isn't it?

Thanks

I am aware that there is no official installer for this aircraft for P3D5. So I simply redirected the installer to my P3D5 directory. I can load the plane but have issues with the graphics as shown in the file attached. Some planes I used in P3D4 could simply be used in P3D5 even though they also should not have been compatible so I thought maybe I can also make this one work but it seems I cannot fic those graphic issues. My system runs the new Geforce RTX 3080 as is a relatively new machine.

Do you have any advice on how to fix it? Unfortunately I have deleted P3D4 as i wanted to move onto P3D5.

Thanks for your time.

• The amber cabin altitude light now advises that cabin altitude is above 10,000 feet
• The amber left and right hydraulic flow light is now lit when the associated engine is off
• The green air conditioning hydraulic pressure light now advises that the a/c compressor is in operation (a/c switch to cool)
• The white courtesy light now advises that the overhead flight deck flood light are illuminated (unfortunately together with the panel light)
• The amber hydraulic pressure light now advises that hydraulic pressure is being applied to the landing gear retraction and extension system (during gear operation)

Send me a PM with your email address. Hope you'll like it and please leave a feedback.

Can someone please enlighten me.

Thank you.

Picked up the Golden Eagle yesterday.  Installed fine into P3D v5.  But I had a problem when I tried to depart for my first flight.  This was pretty much my first ever attempt at flying a light twin, and I'm pretty new to flying prop aircraft in general.  So I went though the start up procedure...engines started fine.  I then started to taxi and could do so no problem, but I remembered I hadn't checked my flight controls.  So I stopped and looked at my ailerons and elevators as I moved my stick and they basically didn't move.  I thought ok, maybe they'll respond normally once I'm airborne.  But as I took the runway and attempted to take off, it was pretty much dead stick.  I could steer down the runway, but pulling all the way back on the stick did nothing.  Eventually the aircraft got airborne just from sheer speed, but I still had no control over pitch, and I also couldn't turn. 

I'm sure I missed something during the start up.  Are there hydraulic switches I didn't see, and if so where?  I see something in the normal procedures checklist about removing control locks?  I couldn't find anything in the VC about that, and manipulating the stick did move the yokes in the VC.  So if anyone could shed light on what I did wrong, I appreciate it.  I'm sure it's just my unfamiliarity with this type of aircraft and it's normal procedures.

Thanks.

I think that the engine start (now you have to give a little thrust), the climb rate and the corresponding speed have changed positively.

PS: But now I need much more time at the start to accelerate to 100 Kts. The runway in EDHK is almost not enough anymore 😬

But perhaps that's just me. The Beech C90 GTX seems to have a functioning pressure system so why wouldn't Car-Ala use the same code and make every aircraft pressure system functional. 

I'll submit a ticket but I'm sure I'll just have to live with it. 

Head wind 14kts. Aircraft at MTOW.

manifold pressure: 30.2 in Hg | 1703 RPM| 

Throttle at 77% | Props at 52% | Mixture at 30%

Using Bernt’s FDE.

Running very smooth but certainly cannot get max cruising speed.

How are the results above?

I cannot after many attempts climb any higher after reaching around 11000 feet.

The vertical speed levels off because the c421 cannot maintain enough forward momentum as the speed bleeds off. Even after having the throttle at max, it has no affect. AP pitch setting functions intermittently.

Can anyone advise how I can fix the issues?

I’ve reverted back to my trusty F1 B200 Super King Air for the time being.

On eBay and some other sites you can fine various copies of C421C manuals. Typically you can choose a year of make. Hence before investing $30+ I would like to make sure I buy the one I have in my hangar 😉

I know there's one version circulating online but it's poor quality xerox.

Cheers,

Andrzej

Also one for the PC-12 but I think Bernt made one available earlier for the Pilatus. I don't want to swap these in and inadvertently lose possible mods e.g. from Bert and others.

Just purchased the Alabeo C421 Golden Eagle, and looking to perform the install. Can this aircraft be installed using the newer P3D XML-method (P3D Add-on Aircraft folder), or must it be installed via the more classical method, i.e. directly into the P3D/SimObjects/Airplanes folder?? 

Thanks for any help you can provide.
