Updates all current, Community File empty. Had enjoyed near perfect landings until last update. Almost reluctant to ask for help - I hold a Private license, and have tried increased final approach speeds, flaps 3 vs. 4 , and ensured AT, AP, ALT all off before touchdown. Repeatedly - around 100 ft. above touchdown - I lose control - with over-active pitch & bank inputs. I usually make the landing after hard hit & bounces - but certainly different for me post last updates… I have checked & rechecked my flight control sensitivities and dead zones, etc. - all the same and toned way down… somewhat at a loss… Thks ! Appreciate suggestions - excuse if another repetitive subject… I fly most everyday…

Did you check your assistance options under piloting (especially assisted landing) to ensure they are off?
MSFS has a habit of changing them without notification.

Thanks - setting is off, only setting on is “auto-rudder”. Further investigation has lead me to the “Reactivity” and " Extremity Dead" Sensitivity Settings. Trying to interpret those options specifically with the Longitude. Other responses suggest I am over controlling on the final seconds of flight (from my Private flying days, (150, 172, 180, Warrior, Arrow, P210) - vs. landing a sophisticated bus. jet. Off today to fly touch / go as Sensitivity settings are adjusted, hope it works… Thanks for suggestion.
Found sensitivity profile had changed to previously trial setup - ?? – Returned (selected) my “current profile”, confirmed sensitivities, adjusted reactivity & extremity dead zone (now understood) - 1st “silk smooth” landing in weeks. Followed all default approach & ref speeds and flap settings - left AT on - basically a hands off landing… ! Did not notice profile selection had changed - will note to check in future.

I have noted something similar on final approach, being very hard to hold center line as the runway tends to slide right or left. My solution was to reduce the approach descent speed from the 140 Kts managed speed to around 125 Kts by presetting throttles and disconnecting autothrottle shrortly after Faf. It has become much more manageable. It seems the 140 Kts FMS programmed speed is a bit fast, unless a max load is onboard.

First - let’s rule out system issues. Sometimes after an update you have to switch your flight model to legacy and back to modern to get things working right. I don’t know why this is, but it’s happened before to others and myself.
Second, I too have noticed that the longitude is harder to fly since the update. Part of that is I think due to the reworked flight dynamics. The previous longitude was incredibly float happy, and almost landed like a square wing aircraft. Since the update, it takes a lot more finesse. I’ll guide you through my landing process that is getting 50-200 fpm landings reliably as best I can in a textual medium.
Starting at a 5 mile final - get established on approach to the runway at Vapp +/- 10 knots (the more precise the better, but if you can’t keep it in that range, you need more time handling the plane. Crossing approximately 100’:
- Smoothly start to reduce thrust. You should start to close the throttles about as you cross the threshold, and be at idle by 20’ off the ground.
- Start to raise the nose not to arrest descent, but to maintain the approach to the aiming bars as the power is reduced. This will seem very similar to a typical square wing roundout.
- as the nose rises and the plane slows you will actually experience a slight increase in sink rate. It’s possible to lose too much energy here, so just keep the plane moving towards the aiming bars
- Right before you touch ease off the back pressure slightly. This, counter intuitively, allows the plane to settle into the ground effect a bit, and also prevents a bounce.
I find it particularly helpful to practice an actual pattern. Even though in the real world you’ll almost never fly a pattern in this jet, there’s no reason you can’t. So take it up for a few laps around the block. Each time, make minor adjustments and see if they make things better or worse.
FWIW, this plane is down right squirrely at low speeds.
That said, I see you’ve gotten a good landing, so I wish you much luck landing this fun plane.

Did you also experiance the fixed speed settings in auto speed?
Does not allow autothrust at approach.
I also crashed my last attempts on landig - I have more than 60 landings with longitude.
Citation works fine since update.
Yeah, still struggling here. 4-5 flights, only 1 “decent” landing (both ILS and RNAV). Weight / balance all correct. Speed bugs followed to the “T”. Wait until threshold to pull power - within seconds (any input) aircraft is near out-of-control - with minimal or no input from my pedals or yoke. (Sensitivity curve way relaxed, using 100% reactivity). Have watched tutorials over & over. Wish “TheCorporateDad” would address specific landing techniques post AAU1.
Now, I’m also struggling with FMS - Speed settings. Flight Plan shows all correct restrictions. On manual mode aircraft responds perfectly. But switching to FMS on speed selector - speed setting reduces to 140 kts. Where does that setting come from ?
- yes - I’m enthused to get this right… thanks…

FMS speed is driven by the combination of the SID/STAR you are on, manual airspeed limits, your altitude, your proximity to the departure/arrival airport, and your flaps configuration.
Flaps 1 gives you 200 kias
Flaps 2 gives you 160 kias
Flaps full gives you 140 kias.

Thank you. Cold / dark start at KMSO, Touch / Go, practice - entire pre-flight & flight performance works perfectly - except FMS speed “pre-selected”. I’m at take-off runway - everything set - but switching to FMS mode (on the ground) shows 140 kts. - despite all my weight/balance, takeoff data, etc. all specifying higher (normal) TO & departure speeds. I switch back to manual - all good. I checked FMS twice on downwind, stll shows 140 kts - switch back to manual - then have to reset an appropriate “cruise” speed. Lastly - upon arrival at the 1st IAF, even on manual setting, speed and altitude adjust as planned. Captures ILS localizer & GS - perfectly. Know I am missing something (stupid) here - but trying hard … thanks again!

May have ID’d my FMS Speed Select issue - FMS speed dictated on the VNAV “Profile” page “Active Speed Target Destination Terminal Area” - doing T/Go for landing practice - looks like my short Right Traffic Pattern is in the Terminal area for awhile… try again…

It’s a tricky beast to land. Made even harder when the framerate drops on you as happened to me last night. Still, I managed a pretty decent landing.
One thing to be aware of, in a swept wing jet, 5 knots can make or break your landing. You want to be on vApp coming across the threshold on a 3 degree descent. You want to be on vRef at the bars, and you want to then just hold that attitude as the aircraft settles onto the runway (that part is much the same as you are used to with straight wings) If you try to pitch up to arrest the descent, you’re going to actually increase your descent most often as you can actually reduce ground effect.

Not much success here. I am “super” conscious of Vapp & VRef speeds - and close to ‘spot-on". As soon as I touch AP off, or ‘’’ forbid, turn AT off before 50 ft of touchdown - controls go berserk. ILS and /or RNav approaches (and departures) are perfectly followed. AT / FMS follows speed constraints to “T”. Only the last few seconds of flight (landing) that things go bad. Honestly - IMO, flight dynamics introduced this last update not truly realistic to the Longitude. This aircraft has to have more stability in landing configuration, with good weather / wind conditions - that is currently being portrayed. Almost ready to give up on the Longitude. I’ve watched & re-watched a dozen ++ flights YouTube Tutorials - and yet, my experience remains the same. Trying again, now - but maybe best time for me to move on to another aircraft.

I mentioned this before, but have you tried switching to legacy flight model and back to modern?
What you are describing doesn’t sound at all like the Longitude I’ve been flying since AAU1 dropped.
Also, are you 100% sure that your not getting phantom control inputs from your controllers? What control input system do you have (yoke, joystick, gamepad?)

I switched to Legacy this AM, let Sim reset and settle, then exited. Started again, showed Legacy, switched back to Modern and let it settle. Now flying a 2nd trial flight KHAF - KJAC after these resets. Thank you for suggestion.
I have recalibrated (via Windows) controlling joystick, which is dated (MS Sidewinder) - (and I have a new spare - - i like the simplicity with <10 buttons… etc.) - According to Microsoft calibrations, all working ok. I have also checked & rechecked all sensitivity settings and preferred reaction curves in MSFS Control Options to try to dampen the last seconds of landing input reactions. All input (joystick) inputs work 150% while in take-off, climb, cruise, decent. It is a serious issue just before touch-down - where controls go wild…
Yes, I knw, need to invest n a new joystick.
I’m on MFG pedals ( $$ great ), dual screen, frames are great. It is just the loss of stability upon approaching the last 50 ft before touchdown - I then land hard, out of control, with gear now in the cabin aisle… flight is 100% perfect - landing instability is beyond uncontrolled, for me…
… no good… same result…
Assuming anyone helping - replace my controller. I’ll need to research best option - I like simplicity, and LOVE my MFG’s - but seems after weeks of testing - something happening with “SideWinder” inputs in final landing phase e - which I do not understand.

Ok, the way you describe it this time makes me think you are ending up in a partial stall causing your sinkrate and lateral control to drop off.
I wonder if you should try to land a bit faster. Maybe grab a super long runway and try landing with just a bit of power in, touch and go style and see if the control is a bit better.

Wow - " Just Read The Release Notes" - as suggested MSFS… suggest read update notes… !!
After all these posts - searching update issues - yup - I overlooked removing “panel.FDEFix”
Just managed great flight - everything worked 100% (except weather was off-line). Weeks long effort to resolve Longitude instability landing - appears to have been caused by (my) conflicting file - which MSFS advised (yes, I overlooked) remove that MOD.
Grateful for all replies. Don’t intend I’m a “great” pilot. Licensed, this glitch stumped me for sure. My error 100% Wow - happy sim time now ! Hope this helps someone else encountering same unexpected issue.

Issue caused by “me” not deleting FDEFix file - as instructed in update notes. All working well - - - - knew I was not that bad of a pilot 
can you better explain to me where this fix is located? Is this one of the fixes that was downloadable through the marketplace?
Not a marketplace mod - as I recall. Su update following explained the mod no loner needed, was incorporated. Best of my recollection. I’m still struggling w/Longitude issues - current effort focusing on my MFG Pedals vs. MSFS Sensitivity settings… trying… MFG suggests use there “configurator” alone - leave MSFS setting at default. My approaches are 100% fine - but upon close to threshold - sensitivity and aircraft instability goes haywire. End up bouncing 2-3 times before I can get settled on runway… ouch…
Way expired (time) answer - to my Longitude landing control issues. Hopes it helps someone else. I use MFG Pedals. The MFG Configurator is the “ruler” - as their instructions have (always) said. I had set both sensitivity settings (rudder) on MSFS, and MFG Configurator - and it destroyed stability upon landing. I reduced MSFS settings to -0- sensitivity (default) then went back to MFG Configurator and checked null zones,and sensitivity from there. Works a charm… I’m now hearing light touch-down screeches again…
