The Longitude is my favorite airplane to fly and I greatly appreciate your efforts to improve it. Thank you very much.

Sorry that im not getting back earlier. i use a community folder manager and there was something wrong with the files in it. now it works very well! thank you!
Can someone help me?
The Top Speed of the Citation Longitude seems to be 476 KT?
Why i get a overspeed Warning at Mach 0.6 (GS 382KT) at Mach 0.59 it disapears.
Did i something wrong?
Maybe because youâre at 12,000 feet. Thatâs not an optimum altitude for a jet engine. See what happens when you get to 30,000 or 43,000. Keep your indicated airspeed at 270 or 300 and climb until your and your true airspeed will increase while you decrease your indicated airspeed. It might even decrease all the way to 234 or close, but your true airspeed will be much higher. Take a look:

Ah OK! Thank you! I followed the indications from MSFS ATC, they suggested me the 12â000 ft. The flight lasted only 45 minutes and I chose Low IFR Routes. (Should I always take The High Routes?) Unfortunately, the MFSC ATC in Europe is (still) a disaster. I will try this out tonight! Thanks.

only then its a long range flight.
Flight Level( or Altitude)= Distance in nautical Miles

You donât have to if the distance is short, but know that you can only achieve optimum speed at higher altitudes because the jet engines are built for high altitudes. At these altitudes they go faster and use less fuel. On a jet like this, Iâd stay at around FL200 (20,000 feet)

you cant go fast at low altitudes because the air is too dense.
As you go higher, the air will be less dense and your TRUE airspeed will be faster, but your indicated airspeed will be slower.
And top speed of .84 will not always be achievable if air temp is too hot compared to ISA
Altitude wise, low IFR (less than FL180) should be we flight that are about 15-20mins or a max of 100nm
Other than that go higher

Mission profile for Longitude almost always includes a cruise altitude above 40000 feet. Even on short flights of 300 to 400 nautical miles the Longitude will be flown at its best cruising altitude which will be between FL400 and FL450 and, if possible, at the maximum of FL450 (assuming taking off with a small fuel load). Why? Because the aircraft is most fuel efficient at those high altitudes, even accounting for fuel expended to climb there. The next version of my mod package should have a much more realistic fuel consumption pattern where the a/c will be much less efficient at lower altitudes and where it will burn the less and less fuel per mile traveled as it goes higher.

I downloaded this fix months ago, and itâs the only way I can fly the Longitude, so many thanks to you. When I see the livery selections, I see the âTextron Aviationâ has the âFDE Dix V1.60â designation, but the âTextron Aviation Modern Cyanâ (which I fly) of course does not. However, I thought I read in your notes that your fix covers all Longitude liveries.
So hereâs my problem, which may or may not be related. When I activate the AT (with speed set to about 305) and get to about 35K feet, the plane starts to porpoise. It lasts until I get to my cruise altitude, which is generally 45K. Iâm guessing Iâm doing something wrong but unfortunately I donât know what you would need to know from me. If you (or anyone else) would give me some pointers on what Iâm doing wrong I would appreciate it.
Thanks so much and thanks for creating such an awesome addon!
Sorry I donât have an answer to your question, but which one is Textron Aviation Modern Cyan? Do you have any screenshot?
Noob question 1 - does the indicated airspeed decrease as the measuring equipment relies on air pressure which is obviously lower at high altutudes?
Noob question 2 - why should I switch to MACH units and when should I do so? Is that related to air pressure too?
Noob question 3 - When should I use managed speed mode v manual speed mode? I donât understand what these controls do at all
Sorry for the noob questions, but Iâm really not sure what Iâm doing with this aircraft yet.
@Dakfly0219 this mod is awesome - thank you so much
1- pretty much yes
2- because MACH is the speed you go through the air. at lower altitude your indacated speed is pretty good, but as you climb, if you set FLC at 270kts than your indicated speed will start to decrease while your true speed will rise, but the plane will want to keep the same indicated speed wich will mess your climb to a point where you wont climb anymore. So by switching to MACH, your plane will keep that value (say .76)
Problem is that in MSFS, there is a ââbugââ that the MACH number you selected for the AP is not changing as you climb descent (basically it stays with indacated speed). So dont use mach hold while climbing/descending, only on cruise (as long as they dont fix that problem)
MACH is calculated with air density + air temp
3- always stay with MAN speed mode, set 250kts until 10 000â, than set 270kts for climb until about FL320 than switch to VS at around +2300â/min to keep a TRUE airspeed of around 435kts until cruise altitude. Youâll have to manually decrease your VS as you climb to keep that 435kts

The mod should apply to any Longitude liveries installed in the community folder provided the publisher uses the typical file format and structure for livery mods. The variation/livery description text is only updated by the mod for the default stock Longitude livery.
With respect to the porpoising behavior⊠Iâd need to know if youâre attempting to hold 305 KIAS or KTAS. And are you trying to maintain that speed all the way to cruise? If TAS thatâs too slow and the autopilot will struggle to hold a stable attitude as your indicated speed becomes too low. If KIAS I would expect it to be impossible to hold that speed (it will decrease as you reach higher altitude and the a/c becomes thrust limited) and I wouldnât expect porpoising unless you are using an unreasonable climb angle. Once at FL300 and above youâll need to maintain at least 430 KTAS for proper flight, ideally higher, like 450 KTAS. Your climb rate at FL350, if close to max fuel load, will be about 1000 fpm and then drop into the hundreds as you get above FL400
Based on what youâre stating, I believe my angle of attack is way too high. Iâll drop it down and see what happens. Thanks very much for taking the time to reply.
That was it! My angle of attack was way too high. I reduced it and she flies like a dream. Thanks again. Without you, a lot of us would have given up on this beautiful jet by now.
Guys can you confirm if you can arm the ground spoliers ? I just installed 1.6 and cant get the ground spoliers to auto arm when pressing the button. It worked with previous versions of the mod. Thanks for checking.
Works for me. Iâm flying it now.

Works for me both by clicking it and assigning a button to it. Does it go to norm when you push the button? Also you probably already know, but just in case, you have to rearm it if you for any reason deploy them and then stow them.
