Vision Jet won't slow down for landing

Hi there,

I am rushing with throttle management on the Vision Jet. Even if I put in manual at 85kt the plane looks like it is accelerating while close to the touch down.

The only alert I notice since taxing is this “Stall high speed” message on the PFD

Can u tip me somehow?

Thanks

The VJ approach speed is 100knts and touchdown around 80knts. How slow do you want to go?

It accelerates. I have seen a real life flight and the pilot says that on landing the vision set speed accordong to flaps…i will give it a try

Are you using auto throttle? Maybe check you don’t have flaps bound to another command? If anything the vision jet is quite draggy and slows down drastically with the throttles pulled back even while clean.

In the sim the vision jet won’t set speed according to flaps. The real plane will but it’s a feature that is missing on the default 2024 vision jet

The stall speed high CAS message is because you turned on “wing and stab anti ice” there s a button to clear it in a menu on the G3000 but it’s inop in 2024. So if you activate “wing stab anti ice” you’ll just have to live with the message for the rest of your flight

The Cirrus Curriculum teaches the “Cirrus Stabilized Approach” where you come out of 250 knots into the Terminal Area, slow down to 140, then down to 120 with flaps 50 percent before the Approach. With about 1 dot to go before Glide Slope/Glide Path intercept, gear down and slow to 100. In the Final Approach, slow to Vref +10 to Minimums, maintain stabilized. At Decision Height, disconnect AP and complete landing by handflying and reducing power as required until wheels contact.

A couple of things to note about the above that the MS-Asobo Vision Jet makes a little more difficult:

  1. Flaps Speed Schedule is missing.
  2. Gear is SAFELY DEPLOYABLE below 210 knots - if you want to throw out a boat anchor, you can if you’re below that speed, but you shouldn’t have to until it’s actually time to put gear down - please see below.
  3. AP will force a disconnect automatically below 400’ - that is absolutely incorrect avionics behavior. The AP will fly you to the ground if you let it. If you are above 400’ it will stay on. If you are below 400’ then it will NOT turn ON if it’s OFF. That’s the correct behavior.
  4. All those Speeds can be easily managed by hand - but the aircraft literally knows where you are in the flight phases right up to the Final Approach Fix - so it should do it for you automatically - so keep AutoThrottle in FMS mode.
  5. After the FAF you can take throttle over - what we do in the FFX Vision Jet is to remain in AutoThrottle, but switch to MAN mode - I can then use my IAS knob to manually dial in speeds like 100, 90, 85. Once I need to cut throttle, I simply pull on my throttle axis which programatically forces AT to disconnect.

Is it normal that even if you never turned on AT, it turns itself on while on landing approach if you go too slow? In one status screen in the plane I found, it said VREF 79kts so thats what I was trying to slow down to but the plane kept fighting me, enabling AT and accelerating. Also it kept warning me about having flaps 100% with anti ice even though I had turned anti ice off.

No, AT should not come on unless you command it.

well it is coming on automatically, seems like a pretty huge bug

The warning about the flaps is cautionary for landing with possible ice.on the plane. Landing at 50% flaps in that case.

But like I said above, if you enable wing and stab anti ice you’ll get the CAS message about stall speed high and it’ll also warn you when going full flaps. The button to clear that is inop so you just have to deal with it for the flight.

If you’re not in icing conditions just leave wing and stab off for the flight. Pitot heat and engine anti ice are all I fly with unless in icing conditions and picking up visible ice.

Make sure you don’t have any binding conflicts. It shouldn’t just turn AT on for no reason, especially if the autopilot is off. The vision jet has underapeed protection but I believe it just pitches the nose down I do t believe it activates auto throttles

I have flown the Vision Jet quite a bit in 2024. What I noticed and believe I read some confirmation somewhere on the forum, is if you get close to stall speed, the plane will accelerate on its own to prevent stall. With lots of practice, I have gotten much better at power management and now love flying around in the Vision Jet. It was very frustrating in the beginning.
