Can someone please tell me what the "Wing Flow" ant-ice button does? Options are from left, normal and from the right. Is this bleed air flow direction? The actual IRLmanual is no help as it just states the obvious.

AI is now our friend:

"On the HondaJet, the anti-ice system prevents ice buildup on critical surfaces, while "Natural Laminar Flow" (NLF) technology is designed into the wing structure itself to reduce drag

. The anti-ice system utilizes electrical impulses to vibrate wing leading edges, shedding ice rather than using engine bleed air. 

• Anti-Ice System: The HondaJet uses a sophisticated electrical system, where actuators in the leading-edge erosion shields create high-frequency, rapid vibrations to break off accumulated ice.
• Wing Flow (Natural Laminar Flow): This is not a "button" but a structural design feature where the wing and fuselage shape allows smooth, undisturbed air to flow over a larger portion of the wing (44% on top, 60% below), minimizing drag for better fuel efficiency and speed.
• System Operation: The ice detection system often operates automatically, allowing the pilot to focus on other tasks, while providing warnings in the cockpit. 

It is important to note that the anti-ice system is designed to prevent ice buildup rather than remove it once it has heavily accumulated."

There is a switch on the anti-ice panel though that says Wing Flow.

Maybe we will get a POH for the sim version soon.

 

AI Overview:

 

The

wing flow switch on the HondaJet (specifically, thermal switches in the hydraulic system) monitors, manages, and regulates hydraulic fluid temperature to ensure proper operation of wing surfaces and systems, such as flight controls. This contributes to the aircraft’s specialized "Natural Laminar Flow" (NLF) wing design, maintaining efficient airflow. 

Key Aspects of HondaJet Wing Flow/Control Systems:

• Thermal Regulation: The system uses CPI M2146 thermal switches to manage temperatures in the hydraulic system, which powers surface controls, ensuring they operate within designed tolerances.
• Over-the-Wing Engine Mount (OTWEM): The unique engine placement, combined with specialized wing shaping, minimizes aerodynamic drag, enhances fuel efficiency, and allows for higher cruise speeds.
• Laminar Flow Optimization: The wing design maintains smooth, laminar airflow over a larger portion of the wing surface, reducing skin friction drag.
• Vortex Generators: While not a "switch," small vortex generators on the engine cowlings help keep airflow attached to the wing, preventing premature stall in that area. 

In summary, these components work together to optimize the aerodynamic efficiency of the HondaJet's wings by managing heat in the control systems and maintaining smooth, high-speed airflow over the wing structure.

I will just make the MFD full screen then.

I came here for an answer to this. I would like to see a full-screen PFD.

I got the answer. It is to manually select which engine provides the bleed air for wing anti-ice.

The PFD is unable to go full screen. Only the MFD can.

Here is a video on how to fix bad landings. You have to fly this plane differenty from what you are used to:

Marwan has said over on the FlightFX Discord that he has grudgingly decided to add full screen PFD capability, even though the real HA420 does not have it. So, coming soon…

Sad, I think. Not sure why he caved.

Since users are requesting it, I don't see any harm by adding the option.

So if enough people asked, he should make it a biplane?

Only if it's hidden. 😀

I'm assuming he wants to make his customers happy.

Just seems odd to work so hard and for so long to make a faithful copy of the real thing to then offer an inaccurate version just because a few users couldn't get used to something slightly different to what they are used to. I know it will only be there as an option but I can't help feeling disappointed.
