Nothing to Study in the MSFS Longitude? Think Again.

I often hear that the MSFS Cessna Citation C700 Longitude is pretty OK in depth...for a default plane. But how well does that actually hold up? Well, I take a lengthy tour through the aircraft's mechanical systems and a deep dive into each. Strap in, it's almost two hours!

[@TheRogueGnisha]

The Longitude is hands down one of the best planes in the sim, in my opinion. The level of detail, the depth of the G5000, it's AMAZING! I've had close to 1000 hours in MSFS and 95% of the time I'm in this aircraft.

[@harryharris1738]

Thanks Matt for a really fantastic video! I realise you are really busy but similar videos of the G1000,3000, 5000, etc and the likes of the CJ4 would be very, very much appreciated - as time permits

[@rayharris8113]

Thanks Matt, an incredible work for us; most of which most of us barely suspected existed. A systems depth many pay-ware planes do not provide...

[@skytation]

Fantastic video Matt, great deep dive into the best plane in the game (in my opinion🤓). Thanks again for all the great work on this!

[@dodohoe]

Having flown nearly 1000hrs in this plane, the majority being since its revolutionary AAU, it's no surprise this is in my recommended videos. What does come as a surprise, however, is the depth of some of these system which I've never even considered going into. The robust and detailed avionics were expected, as is the reputation of Working Title ... but the fidelity and dedication to the systems definitely deserve this video. I always believed AAU sent this plane to being one of - if not, the best - aircraft in the base sim for its capabilities. It has always held its own league. Myself and others I fly with (and sometimes with YourControls - which certainly works well enough in this plane) have sent this thing all over the world in our MEDEVAC missions, and it's done everything asked of it. Great work!

[@M2Chris]

Great video! I also fly out of KDPA

[@Lysdestic]

Thank you very much for putting this together and all the work you and the team have done for the sim, Matt!

[@cgonzalez7469]

Wow, great video and great aircraft. Congrats to you and the WT team for making this!

[@jacksorrows6553]

Learnt something new things today. Incredible job with the updates.

[@r.dinelli]

Thanks for taking the time to make such a detailed video, Matt! Goes to show the huge effort by the whole Working Title team 💪🏻

[@LeSaxon90]

I should send this to every Xplane fanboy. Great video!

[@mattnischan582]

Hey now, there's room for every sim in this world. No need to make it a competition! 🙂 The Laminar folks have all the respect in the world from me.

[@LeSaxon90]

It wasn't a dig at X-Plane per say. But only at their fanboys when they claim MSFS is "purely an arcade game". 😎 I started on X-Plane before obtaining my PPL here in the UK nearly 10 years ago.

[@tubeloobs]

​@@mattnischan582 I hear ya, Matt. I really respect what the guys and gals have done at LR with the resources they have. Thing is, at the rate you guys are going with 2024, you just might bump them out of the market. If the new sim's flight model is as good or better than theirs, there will be a mass exodus of the holdouts.

[@tubeloobs]

​@@LeSaxon90yeah I totally get where you're coming from. I don't have anything against LR (well except when Austin decides to say weird things from time to time) but some of their fans are just cringe

[@FlightSimMuseum]

Absolutely brilliant work and thanks for showing us what MSFS is capable of!

[@brunogt1982]

Awesome video and great channel, keep up the good job 👏🏼

[@bigblackahuna7815]

Great stuff Matt! You guys did one helluva job on my primary jet. Really appreciate all of the hard work your team put into it!

[@OnCorLasagna]

Brilliant. I've been flying the CJ4 a lot recently, but I think it's time to switch to to the Longitude.

[@manuelschneider7286]

Hi Matt, a really fantastic video on a great Aircraft. I think it is a fantastic idea to showcase the level of detail in the simulation in such a way. I certainly hope there will be a second video going into the avionics in detail. One question/critique on the Longitude as it is in the sim currently: Is there a reason why the the in game Check List is in such a dire state or are there plans to update it? I would love to see it being updated to include the Section 17 Normal Procedures from the Operators Guide where possible. Having Check List items read out by the copilot is quite a nice feature and can add a lot of immersion especially in VR where going through a PDF file can be cumbersome. It would also help simmers who are new to the longitude, such as myself, a lot with the initial familiarization with the aircraft. I have just started to use the Longitude more intensely a couple of days ago. To be honest, the missing in game checklists have put me off a bit and have sort of given me the impression that this airplanes simulation was a bit neglected so I never really started to fly it in the sim. Only after watching this video and flying it a bit more did I realize what a true gem it is and how wrong my perception of the depth of this aircraft has been. Great work on both the video and the Aircraft!

[@Dirigius]

That was amazing. I'm fairly new to MSFS 2020 and the Cessna Citation Longitude became the aircraft that made it easy to learn one thing at a time on navigation while flying. I'm always looking for more in-depth explanations of this beautiful aircraft. This video is the absolute jackpot. The reference to aircraft manuals I didn't even know existed...chefs kiss. Thank you!

[@casstephens3124]

Bloody hell bro. Lol incredible. !!!!! I've always loved this aircraft. And is the reason I got the premium version. Even on day one I giggled sitting in this thing and just looking at it. Like a monkey with an obelisk. Just beautiful. And youz guyz made it stunning.

[@rockyjetproject1345]

I was thinking of using this plane with On Air airline management. It seems to be pretty darn good!

[@marclanghoff9789]

Wow. What a great Video which explained the functions about the Citation Longtitute in MSFS which gives you definetly another view on this plane. Great work! If it would have a Tablet with a Load Manager and so this would be the cherry on top! Love this accuracy. 😃💯❤

[@mattnischan582]

Thanks for the kind words, that's very generous of you! Given that there are only a very small number of load stations and a single set of tanks, we don't feel that something like a tablet with a load manager could add much to the experience; it would look basically the same as the sim's weight and balance panel.

[@Ahmad310x]

Incredible video showing the depth of the Garmin system you guys developed! WT team is such a treasure and we are so lucky to have you guys putting all this work into improving the sim! Cannot wait for the Epic system and the possibilities that will open up for future bizjets in MSFS. Thank you for all the hard work!!

[@mattnischan582]

Thanks! Just to be clear here, the Epic we're doing is just the Epic 2, not the Epic 1 or any other Epic variants, like EASy I, EASy II, etc

[@_pianoN_]

great video, thanks for investing the time to do the citation justice. only 2 airrcraft i really fly in msfs are the longitude and the 787-8\787-9, personally i love both of them.

[@zachburgess2289]

Thanks matt, this give me a whole new look towards the longitude. Originally I thought the longitude was not a study level plane. Are you guys going to make a functional HUD? I think a lot of us would absolutely love that.

[@zachburgess2289]

The pdmg 737 hud is pretty good, I think it would get a lot more people flying the longitude. Nothings cooler than a biz jet with a head up display.

[@mattnischan582]

When we worked on the plane, the HUD was not certified for use or installed in any aircraft; similarly we could not be granted access to any documentation for it. It actually just got certified for use a couple months ago only, and is installed presently in just a single Longitude. So, it's on our list but not a high priority at the moment, as IRL as a pilot you would never really encounter one.

[@mikebakkeyt]

Hey Matt - at 37 mins where you demo the PTC gen logic, the synoptic still shows a white line between the PTC and R EMER which suggests the PTC isn't connected to the bus. Am I understanding wrong?

[@ismaelyasri3889]

great video man. what are your pc specs?

[@topofthegreen]

Is nothing more than a really good video game.

[@brandonbinder5572]

Wish it had wingflex

[@mattnischan582]

I know simmers love wingflex, but planes the size of the Longitude have little to no wingflex, so to add it would not really be very realistic.
