Vote here if you don’t like that big mirror: H125 Cargo Mirror Way Too Big
IMHO it would be great to get this kind of horizonal EFB mounting position. Right now it’s obscuring so much view. On some missions it’s very difficult to adjust the hovering position because you need to use EFB (fully zoomed in) but EFB is blocking the view so I need to use it in detached mode, but then it’s too big even with SMALL setting selected. At least that’s how I do it without VR

Do all H125s have a idle selection on the engine start switch. I was just in one for heli skiing and noticed there was OFF - IDLE - ON for the ENG START switch. Also it seems the rotors take a long time to spin down when turned off.
I managed to create an “improvement” package to replace the GPS with PMS50 GTN650 in this default Airbus H125 helicopter, it’s not finished, there are still some issues, but it’s already usable and really helpful.
It’s a bit too shiny, you can turn down brightness manually using the System/Backlight page on the unit.
And as an extra feature, it enables you to control the transponder, that was seriously missing in this helicopter.
See the project page on Gitlab (linked below) for some additional notes and install instructions.
Any feedback or help with the outstanding issues is very welcome.
I hope this also puts to rest the conspiracy theories, that the default streamed planes are locked and not moddable

I was thinking how we could make sling loading work assuming we can’t have working mirrors (P2P or whatever technology must be used), I came up with this idea:
I know it looks immersion breaking, but it’s no less immersion breaking at the moment in the game IMHO. The “shadow” could get sharper the closer the load gets to the ground and more blured the higher it is over the ground, the “grid” could use thicker lines over the target area (and maybe some kind of circle to indicate the borders of the area where we are supposed to put down the load). Actually, the grid can be completely invisible and only appear over the target too
For a reference here is how a commercial H125 simulator does it (it’s loftdynamics and it uses VR with a mix-reality cockpit), if we can’t have it, then we need some kind of workaround hence my concept idea

In the H125, the following sounds are missing:
- Turbine start sound, when starting the helicopter
- Horn
- System startup alerts for the helicopter such as WLT sound (warning light chime)
- Fire test
- Radar altitude
Others missing features
- Servo test is missing (we need a key biding)
- warning light test (WLT) is not key binding please add it…
- Squawk is unable, VATSIM or similar, pilots can’t fly…
After update [1.2.8.0] when turn off engine in flight, the VEMD goes all black, because aircraft battery was drained this should not happen, this is going to happen now because I/GEN goes crazy up to thousands Amp (gen off to avoid) because we are using the emergency procedure for engine fire, and this is one step…
Before this update was fine…
It needs attention…
Missing features in the VEMD (Vehicle and Engine Multifunction Display):
- Scroll should change vemd pages FLI and ARC mode, it shows torque, temperature and N1 (will be need a key biding).
- Demister and heating buttons axis option for it, to reproduce de turning on the physical knobs (hardware panel)
- The same axis options to the vemd on off buttons, bright and lightning
- Final fuel values and the calculation of usage until depletion.
- Some basic VEMD pages, such as the report page.
- Performance page, allowing the input of weight data to verify IGE
Observations regarding fuel values:
- Fuel consumption values are far too high compared to the real aircraft. The average consumption at high performance is 180 kg/h.
Issues with the VEMD needle:
- The needle is behaving unrealistically, showing the engine usage percentage (FLI - First Limit Indicator) Slow action, throttle issues, start helicopter counting twice.
- Indicator arc (engine arc) is not in the beginning it’s missing the arc monitoring (in a start for example), this part of the engine arc should be hatched the same way as its end.
Cyclic behavior:
- The cyclic is functioning with less power than the engine.
- At full engine power, the cyclic is nullified, which never occurs in the real aircraft. This should also be corrected!
Cyclic functionality:
- The cyclic is overly forced forward. Normally, you apply forward pressure, but once the aircraft reaches the desired angle, the cyclic should become subtle, returning to center. For example, at 130 knots during a cruise flight, the cyclic should be centered because the mass is already adjusted. It should not remain forward, forcing the pilot to use basic controls incorrectly.
Performance issues:
- Maximum speed and maximum altitude are incorrect: they should be 155 knots and FL230, respectively.
These are my suggestions to improve this wonderful aircraft, enhancing immersion for more experienced pilots and providing better performance in flight for beginners.
Before Sebastian says this isn’t possible, these calculations should be refined. As a computer engineer and pilot, I am providing a more detailed opinion on processes already known by Asobo, but with subtle adjustments that could benefit all helicopters on the platform.
To improve the dynamics of the cyclic in MSFS 2024, it is essential to adjust the rotor’s aerodynamic model and the control interactions to more accurately represent the physical effects and real behavior of a helicopter. Here are some technical suggestions that could enhance the level of precision:
- Detailed Blade Element Theory (BET) Calculations
• Strengthen the segmented calculations of rotor blades to ensure each section responds accurately to changes in the angle of attack and variations in airflow during acceleration and cruise flight.
• Incorporate modeling for induced flow distortion, especially in high-speed flight regimes. - Torque-Motor-Rotor Integration
• Recalibrate the relationship between motor torque, rotor RPM, and cyclic limits to prevent the engine from excessively compensating for a lack of rotor disk angulation.
• Simulate progressive collective pitch adjustments to avoid efficiency loss in high-performance scenarios. - Rotor Disk Modeling and Gyroscopic Dynamics
• Incorporate the gyroscopic effect of the rotor disk more robustly, ensuring cyclic movements reflect the helicopter’s physical behavior.
• Simulate rotor disk deformation during translational flight, especially when the cyclic is pushed forward for cruise. - Airflow and Downwash Dynamics
• Expand the simulation of airflow around the helicopter, including downwash and recirculated aerodynamic effects.
• Better model the behavior of rotor blades in uneven airflow, such as during crosswinds or rapid descents. - Physical Simulation of the Cyclic
• Implement an inertia and resistance model for the cyclic to ensure it responds more naturally, returning to neutral proportionally to aerodynamic forces depending on flight conditions. - Ground Effect and Lift at Altitude
• Adjust the ground effect to vary based on altitude, surface type, and aircraft weight.
• Include a gradual reduction in lift due to air density changes at different altitudes and temperatures.
These technical improvements can provide more accurate and natural cyclic control, eliminating the need for excessive pilot compensation and delivering a more immersive and precise experience consistent with the expectations of an advanced simulator.

You are aware that MSFS2024 has CFD, right? It has some issues (what does not in MSFS2024…) as detailed here: SU1 Beta Helicopter ground effect is still wrong
This is the only point I can’t agree with- AFAIK the cyclic remains displaced forward compared to how it’s placed on hover (helicopter will pitch up when entering ETL). I would agree that it seems that at the moment H125 is lacking pitch authority on cyclic because sometimes you will have to push it forward to the max deflection and it will still pitch up in certain conditions, but I would not agree that the cyclic should return to center in cruise.
Yes it is centralized it is the Airbus systems…
Yes I know… this is very buggy
There is no AFCS in H125 if that’s what you are referring to when you say “Airbus systems”, and even in H145 AFAIK SEMA doesn’t have enough displacement authority to nullify the need of the forward cyclic displacement in cruise.
Agreed.
I don’t know about the H145, but the default H125 in game needs too much forward cyclic for cruise. It’s slower than it should be for the amount of forward cyclic needed.
In the real helicopter, the cyclic does not return to center for cruise. You still need forward input applied, but it’s excessive as currently modeled.
The hydraulic boosted controls in the real thing are so well rigged and balanced, that they don’t need trim. There is not much force in the controls to fatigue the pilot. The cyclic pretty much stays where you put it.

In the Airbus H125 (AS350), the cyclic tends to stay near the center even in cruise flight due to the helicopter’s aerodynamics and stability. With 15 years of experience as a pilot, I’ve noticed that the rotor system naturally balances itself once in level flight, reducing the need for constant cyclic inputs.
The main rotor has a built-in damping system that helps maintain stability, preventing excessive oscillations. Additionally, the horizontal stabilizer on the tail plays a key role by generating aerodynamic forces that counteract the forward tilt typically caused by the main rotor. This means I don’t have to push the cyclic far forward to maintain cruise flight.
When the helicopter is properly loaded and the center of gravity is within limits, it naturally maintains a neutral flight attitude, requiring only minor cyclic corrections. Unlike some more advanced helicopters with force-trim systems, the H125 doesn’t have an automatic hold on the cyclic, but its design allows it to remain stable without excessive input.
In practice, once I establish cruise flight, the aircraft tends to hold its attitude with minimal cyclic pressure. I may need to make small adjustments for wind variations or weight distribution, but overall, the cyclic remains near the center, making the H125 a well-balanced and predictable machine in cruise conditions.

When I flew the H125, the cyclic didn’t feel positioned any differently than any other helicopter that I have flown. It was just lighter, and easier to keep steady than Robinsons.
Where have you flown Astar’s? There are quite a few operators in my area.

when selecting the passenger version of the h-125 and choosing the livery, it flies to the desktop.
I cant get the H125 to work. I tried to take the Turbine certification and the Heli would never warm up and Power on
the HUD says 0 and RPM never gets over 24. In addition I see Fuel P in Yellow, ENG P, MGB P and HYDR all in red. I have checked all fuses and rotor brake is Off. I have spawned on runway or ramp and I cant get this H125 to work at all. I have followed check list or told it to autostart using Cntr +E and the result is the same. Any help is greatly appreciated
Fuel pump on? IIRC it has to be for the H125 to fire up.
Yes Fuel Pump was on. I flipped it off and back on and no change on the Yellow Pump message
I determined this was an issue with default TCA mappings which had the fuel valves tied to a switch I was unaware of. after disabling all devices I added them one at a time until I found the issue.
