Not AAU1: Cessna Citation Longitude Flight Dynamics Modification Project

My dream is for the HUD to be made functional.

Even though it’s not functional in the real world aircraft? Like none of the actual flying Longitudes have it working?

Just a FYI, we still have not got the HUD certified on the real Longitude.
Not sure why it is taking so long.

Whoah, I didn’t realize that was the case. So all the Longitudes out there have it, but it can’t be enabled?

Only a few have the provision wiring and brackets, still waiting on certification to fully install.

@TXTAVDan - It’s awesome to have someone with direct knowledge of the Real Longitude here.

So, a question to you (or anyone): I fly (“sim”) both the Longitude and the CJ4 (Working Title) extensively, and always use the Auto Throttle on the former. When I’m using the A/T and tapering off the speed as I descend to land, the Longitude slows quite rapidly down to whatever I set it. In contrast, the CJ4 can be hard to slow down
even at the standard 3% descent and minimum throttle I sometimes have to use spoilers to get it below 250 knots at 10,000 feet, and down to 200 knots so I can finally put the flaps/gear down. Does the real Longitude react pretty similarly, i.e. being able to decelerate so quickly?

Not sure, I would have to ask the pilots, the times I have flown on the 700 I didn’t notice much SB deployment, seem about the same as the sim, the citation X I have flown on around 250+ times and the SB were used often on it.
I can’t speak for the CJ4, I only supervise the Model 700 Flight/Delivery operations.

You should really ask on the Working Title Discord, as there is a CJ4 type-rated pilot on the WT team.

You should try the working title version. I fly CJ4 exclusively and I have no issues controlling approach speeds. the use of spoilers to reduce speed is used in the real world, so don’t shy away from doing that.

Svorg: Welcome to the community!

I do fly the Working Title CJ4 extensively. This is more of a sim realism question about the Longitude, i.e. “does the real-life Longitude decel (with auto-throttle) as quickly as the sim version?”. It seems a bit unrealistic that when I’m descending and I back down the Longitude A/T from say 250 knots to 220, it decels in about 15 seconds, whereas the CJ4 takes quite a bit longer when I pull the throttle back.

When it comes to “controlling approach speeds”, the CJ4 is very easy to control with flaps/gear down, but it’s really about getting it down below 200 knots, the max F15/landing gear down speed.

IRL, the Longitude auto throttle will target a 1kt/sec acceleration, so your 30kt speed change would take about 30 sec if the auto throttle doesn’t reach idle. However, it is a very slick aircraft and can be difficult to slow down without adding drag, usually flaps. Speed brakes help, but they’re relatively small compared to other Citations, and only extend half way with full flaps.

@Nerbulus Thanks a lot for the panel fix, much appreciated!

How to turn External Power ON ??? it seems not working, always needs to start APU, but I’ve seen it turned ON on several videos from Overkill’s prod.

You could read the documentation. But the external power button is near the battery buttons.

On some stands, external power is not available

Hi All

What does the marker [M] mean on the Altitude tape on the PFD please

You’re passing over the (M)iddle Marker in an Instrument Landing System.

thank you appreciated

What documentation? Textron’s?

Wow, 263 Kts at 1170 ft with 6850 V/S. So much for 250 under 10 rule.
