M-346 MASTER Beta Test and To-do List

IMPORTANT! All Beta test slots have been assigned. NO NEW APPLICATIONS WILL BE ACCEPTED.

BETA 1 of the Aermacchi M-346 Project is finally here! The build is not really feature complete but it is completely flyable and ready for test.


To apply as a Beta tester for this project, please send me and email at with the following information:
- Real world and simulation experience (Note - Beta is open to ALL levels of experience...I ask the question just to know what is your level of aeronautical knowledge)
- Your system CPU, GPU, RAM and OS
- The simulator you intend to test the M-346 on (exact version of P3D, and if it is with or without VRSTP)
- Any special reason why you think you should get the Beta (be honest, no flattery please)

The subject of the email shall be: M-346 Beta Test Application

Please DO NOT apply if you do not think you have the time to test it (consider 3-4 hours minimum).
Also, just to make it clear, this is NOT a paid position - in any form. I will decide to provide or not complimentary copies to testers at the end of the Beta stage.


The package embraces the "Add-on" approach available in P3Dv4 or v5 - therefore package shall be installed in your Prepar3D Add-ons folder in your Documents folder.


A WIP manual that includes operational checklists is available for download by clickling HERE. The checklists are close to the real world one, but have been (partially) amended to reflect changes in the simulation. Testers are encouraged to go through the checklists and report discrepancies.

The aicraft embraces a COLD AND DARK approach.
If you start your scenario on the ground, the aircraft will shut down all its systems forcing you to a full start.
While you are encouraged to follow the checklist and report any major inconsistency, AT MINIMUM, to start the aircraft you must follow these steps:




- APU MASTER/STOP PUSHBUTTON (left console, close to the MFD) -> PUSH (the APU START button lights up and shows "RDY")

- APU START PUSHBUTTON ->  PUSH (the caption becomes RUN and blinks, indicating that the APU is starting up...when the blinking stops the APU is running)

- RIGHT ENGINE MODE SELECTOR KNOB -> Set to START/IDLE (the START pushbutton illuminates)

- RIGHT ENGINE START -> PUSH (the button starts to blink, when the blinking stops it means that the engine is running and APU can be turned off).



NOTE: To arm the ejection seats, you must remove the safety pin AND set the arm switch to ARM. The procedure must be repeated for both seats, unless the ejection sequence lever in the backseat has been set for solo flight.

NOTE: Checklist would request you to perform the EGI Alignment procedure...which is however entirely optional. Despite the IN/GPS page readings, navigation accuracy is not affected by the procedure, which has been included only for users who want to perform it.


The aircraft is fully flyable and should not have glaring omissions. However, at present, the following features are missing or incomplete.
- Electronic Warfare (note: in the real world, the vanilla and the FT versions do not have it...addition is planned for the FA version)
- HMD support (still TBD)
- Special Alert system
- Voice alert system (it's in there...but needs improvement)
- UFCP steering point, waypoint and flight plan management
- Pre-Planned A/S Targeting
- Targeting Pod


The preferred way to report bugs is to add a comment to this post, specifying what is the experienced malfunction and when it happens. Pics are welcome.
Alternatively, an email is good to. Comments are preferred so that other users can see them.
It is not a race, so take your time. The simulation is quite complex, so it may take some time to get acquainted with the plane… I'd suggest you log at least a couple of hours before submitting any feedback.
Also, PLEASE, before posting a bug make sure it is not already in the list below.


Red - Higher priority: a severe bug that may hamper the usage of the aircraft
Yellow - Lower priority: definitely a defect, but not a high priority to solve it
Green - Problem solved, o mitigated to the level that it is acceptable.Dark Green - Problem solved or mitigated before the Beta 1 release.
Blue - Comment, nice-to-have features or suggestions

Hi Dino,
I also did my first short training flights with some touch and go's.
First of all it handles really well and it seems realistic as a trainer. Followed are my first observations:
The airbrake has a graphical issue: the piston rod is not centered when extended and retracted (will send you a Email with 2 pictures of it);
The Master Caution Reset Switch does not work (no reaction on push / should reset the light, shouldn't it?);
The Take Of Trim Indication on the CSD (is this the name of this small display left of the MFD) is behaving weard. It shows up and disappears for no obvious reason. It is not related to the Take Off Indication on the MFD FCS Page;
Also with the parking or normal brake engaged the airplane moves forward very very slowly (like it had been on old FS days on many planes);

Overall I'm really pleased by this very good work...

Dan said...

Hi Dino, did a flew hours on both V4 and V5. One the main thing I would say for now is that the aircraft feels a bit overpowered.External lights might be a bit too bright. Other main points are already mentioned in the 2 previous posts.

It is a gorgeous looking plane you just created Dino.


Florian said...

Hello together,
one small bug which I found out today, had only time for a quick ride today :-). If you start your sim and start inside the the 346 (I mean if you select it on the welcome screen) the CSD and the EFDP doesn't power up when switching on the BATT and remain off the entire flight. I know that usually many addons require to start with a default airplane and then select the addon. But this is a observation I made. As soon as you select another variant or another aircraft and load teh 346 again both displays shows as usual.


Anonymous said...

Hello Daniele,
about your first bug: is it possible, that it is the same as mine described before? Is the EFDP on in this case? And was the CSD on before start up (on Batt)?

Best regards

ScimmiaSpaziale said...

Hi all.

First THANK YOU ALL for your enthusiastic feedback on the M-346... As you may have seen I have constantly updated the issues list, but I have changed the color code as follows:

- DARK GREEN now indicates the issues detected internally in Alpha builds. I have kept them along with the new ones for you guys to double check in case an old issue shows up again (e.g. the flickering TAKEOFF TRIM indicator... is back from the dead, and hopefully solved again)

- LIGHT GREEN are issues which have been dealt with AFTER Beta 1 release. The plan is to release a Beta 2 sometime in mid may, and release the package around the end of the month.

A couple of miscellaneous notes:

- There seems to be an exposure problem with P3Dv5. Many legacy effects are overexposed, as P3Dv5 introduced new effects rendering parameters. I am working to have something that will work well in both v4 and v5.

- Digital displays not showing up in certain circumstances... I think I have identified the bug.

- Aerodynamic performance. Unfortunately we do not have the performance manual. However the current flight envelope is very close to the ones in the aicraft manual. Roll rate is spot on to the manual figures, but I agree that the thrust is a little high and drag is a little low (probably the latter impacts the thrust).

Also... it seems that some foreign aircrafts (e.g.Israeli ones) have slightly different HUD symbology (designed to match the F-16), but this is not confirmed.

The engine cut off buttons labeled engine 2 and 3.
APU and engine start up sequence sound plays only once. so if stop the engine and then restart it you get no sound so cant judge when to switch to run.

Donald said...

The Altitude select knob is labeled right engine start

Donald said...

HUD overall size small compared to HUD glass making it harder to read which exhasperates the brightness issue.

The location of the HUD switch is not obvious and manual does not specify

Donald said...

Maybe make the HUD 10% bigger non the glass?

ScimmiaSpaziale said...


HUD frame dimensions are correct. Display area and view angles have been changed for Beta 2. HUD controls will be detailed in the documentation.

ScimmiaSpaziale said...

@Daniele Issue was already in the list code M346OT15 and was already solved

Donald said...

I find on my Projector/ dome setup I cant really read the HUD very well It would be good to have some sort of brightness setting so you can adjust it to what you need for your set up.

M346VC47 - Brightness of HUD considered not sufficient - To be checked.

Hi Dino,
I have a few observations from a few hours with the M-346. Some may be user error.
System: Xbox series X.

Heading bug reacts the opposite way (from all other aircraft) when using the Xbox controller to select heading. ie right button makes bug move left and vice versa.

Aircraft taxis with minimal throttle movement and keeps accelerating when throttle is moved back to idle. similar in nature to the King Air.

The aircraft to me seems to be way over powered with minimal throttle needed for high speed flight, when compared with similar aircraft.

Aircraft oscillates when AP is engaged in APR mode. AP was disengaged and an attempt to  re-engage AP was unsuccessful.

Clock shakes severely when flying in bad weather.

Flap/Speed Brake/Undercarriage indicator went blank during flight with flaps and undercarriage not able to be selected. (one occurrence).

UFC goes back to the COMMS page after making other selections AP selections etc (is this by design).

Are there manuals (POH) for any of your aircraft that Xbox users can access?
