[RELEASED] Skyward Simulations Cessna Citation C680 Sovereign+

Features>

Aircraft Systems

  • Electrical: Detailed bus logic with 170+ simulated circuits. Includes battery temp, ground power logic, and interactive circuit breakers.

  • Anti-Ice: Fully simulated system for wings, engines, stabilizer, and windshield with temperature monitoring and CAS alerts.

  • Bleed Air: Accurate pneumatic layout with APU integration, auto source selection, and links to ECS/anti-ice.

  • Fuel & Hydraulics: Realistic fuel crossfeed/pump logic. Hydraulics model accumulator gas/fluid dynamics and parking brake.

  • FADEC & Autothrottle: Thrust limits for all phases, TO servo logic, and accurate FMS speed cruise data.

  • Pressurization: Automatic control with separate cockpit/cabin temperature zones.

  • Datalink: Fully simulated ACARS/CPDLC (FANS 1/A+/ATN B1) with SATCOM/VHF modeling. Handles D-ATIS, clearances, weather, and ADS-C.

  • Other Systems: Oxygen/water usage with state saving, control locks, and a Takeoff/Landing Data computer for V-speeds and distances.

G5000 Avionics & EFB

  • Synoptics: Dedicated pages for electrical, fuel, hydraulic, and system summary.

  • GTC (Central Control): Manages datalink (D-ATIS, TELEX, oceanic clearances), TOLD computer, cabin management (lights/temp), and system tests/status.

  • Crew Alerting: CAS with configurable inhibit states (TOPI/LOPI/ESDI) for all major systems.

  • EFB Tablet:

    • Service: Manages payload, ground services, and system states (hydraulics, fluids, oxygen & more).

    • Flight: Displays SimBrief OFP.

    • Checklists: Normal procedures (abnormal/emergency planned).

    • Settings: Aircraft configuration, simulation options, and SimBrief integration.

Visuals & Performance

  • Model: Numerous interactive exterior panels (doors, service points) and cabin details. Optional ground equipment (GPU, fuel truck) and visible crew.

  • Performance: Reported by testers to be in line with default MSFS aircraft.

  • EFB: Feature rich and intuitive implementation for aircraft control, flight planning, and checklists.

Wow, where did that come from!

Apparently they’ve been working on it for two years. The first announcement dates back to June 2024 with one screen of an external model already. It looks great and I can’t wait!

Their DA-50RG was a little abandoned though so I am slightly wary. That looked pretty great too.

I have no experience with this developer at all. We will see then.

Same avionics as the stock Longitude, but with an interactive cabin - so far, so good. If it has a dynamic external registration and a realistic price point, I’m in!

It looks incredible. An mp xbox release planned ?

Any word on MSFS 2020 / 2024 compatibility?

Definitely not my favorite bizjet but it looks promising and the feature list is pretty impressive.

I included tags for both simulators. That’s what their official announcement was saying.

I believe mrtommymxr and boris audio works were involved with DA50 and if they have the same input with this aircraft then that bodes extremely well.

The DA50 is one of my favourite GA aircraft (along with all the COWS Diamonds obviously).

I’ve added an official trailer to the original post.

Still no news about an xbox release ?

According to Skyward Simulations Discord channel this project is on its final approach…

We are getting close it seems! :partying_face:

I’m really looking forward to this one. I watched Emi’s stream and was impressed by how much the developers modeled and you can tell how much they really enjoy the aircraft. I was a little skeptical at having another G5000 aircraft (would it be that different than the Longitude?) but it looks like they spent a lot of effort on customizing the G5000 using real aircraft for reference, and incorporating ACARS is a nice touch.

Yep, always good to see the devs in one of these ‘first look’ types of video.
Good article/interview here too:

https://fselite.net/content/building-sovereign-with-skyward-simulations/

An article from FS News dated last December states this is for both sims. Can anyone confirm is this is still true?

https://fsnews.eu/skyward-simulations-shares-development-update-on-citation-sovereign-for-msfs/

It’s confirmed for both. Apparently one of the main differences is the depth of the electrical systems.

Going to love the systems and electrical depth of the Skyward Simulations Cessna Citation C680 Sovereign+.

Glad they went with integrating the awesome WT G5000 avionics we have in-sim.
