Thanks. Will give that a try

The arrival fuel on the PROGRESS page is still buggy and does not show the correct fuel. You can use a rule-of-thumb though and calculate your fuel use by assuming that you will need 2400kg of fuel for 400 nautical miles - or 6kg (14lbs) per NM. This is valid for "when at cruising altitude", so you can calculate how much fuel you will use until you arrive at the destination.

We thought about it, but there is a reason why we did not include this. On aircraft without automatic alerting of incorrect barometric setting below/above the transition level/altitude, it is procedure to change the settings separately. For example if you fly at FL 210 and ATC says "descend to 4000 feet, altimeter 1032", the PILOT FLYING will change his altimeter immediately to the QNH setting (so he does not forget and the plane levels of at the correct altitude), but the PNF will only change his altimeter as he passes the transition level (so that if ATC changes their mind and tells you "stop descent at FL190" you have one altimeter set to the correct STD value, still. If we had made the altimeters sync, too - it would be impossible to follow this correct procedure with the sync enabled.

Hi team, I have the SYNC Pilot/Co-Pilot Instruments ticked on the Preferences page however it doesn't sync the baro settings. I still have to action that manually. Is that correct? Thanks in advance. Never mind, it appears to be for the speedbug and altimeter bug settings. Would be handy for baro settings though.

Is the documentation from Apr 2016 still relevant or an updated version is expected? Oh, thanks on the update response by the way.

Greetings all, 1. Is there anywhere on the FMC where it shows the calculated fuel remaining at the destination? I can't seem to locate it. 2. On the preflight page the maximum range that can be set is 2000 nm. Doesn't it have a range of upto 2375 nm. Just wondering. Thanks in advance.

Thanks for the detailed reports, I've got these filed!

The aircraft also has to reverify itself outside the main activation system. It will hold a cache for ~2 weeks, so if a conflicting plugin is reinstalled it wouldn't be obvious in that time period.

Not seeing anything obvious in the log, it could be something being a conflict with one of your other third party plugins. I'd recommend seeing if temporarily removing some of those resolves the issue.

Somehow these two buttons stopped working. It happened after the last update but probably not due to the update. I have a honeycomb bravo with the prodesksim challenger 650 upgrade so I have the same buttons at the actual plane. The togo and disconnect buttons work in the sim aircraft so I can actuate them in a pinch but I want the physical buttons mapped again. I had a 650 profile that I downloaded for the configurator so I reloaded that, activated it, went to the plugin menu when in xplane and reloaded the settings. Still nothing. I am trying to figure out 1. how can I get a listing of the settings in my configurator profile? I saw someone had a txt file of their profile settings. 2. how can I tell which profile is actually running in xplane? I assume the active configurator profile is making it across but there is no way for me to tell? 3. When I go into xplane, I cannot tell what button number the togo button and the two disconnect buttons are in Xplane. I am wondering if those are set directly into xplane and not through the configurator? I would love to hear what you have experienced. There seems to be no instructions on how to use the configurator except a few videos online. I have only found one that talks about xplane and that is to set up a prop single. If you have a video that would be great. Laura

thanks !

@Litjan In "most people's" defense, according to the navigraph survey "most people" who sim aren't real world pilots like you and I LOL

it would appear nobody has an answer.

Now i have this same problem. Plane has worked just fine for many flights but not anymore. X-aviation plugin is working and showing that licence is activated. What now ?

Hi All, I'm building a python script to integrate Challanger 650 CDU with Winwing PFP 3N. I've got the proper datarefs, specifically CL650/CDU/{cdu_number}/screen/text_lineX and CL650/CDU/{cdu_number}/screen/style_lineX where X is from 0 to 14 representing the line. The text lines are straightforward and represent the text, but the style lines are byte arrays with 24 bytes (same number as columns) which seem to be representing the style/color of each character. I can confirm through experimentation that different character colors displayed on CDU have different style_line byte elements. I was hoping there is a documentation around what each byte value or each bit in the byte means so I don't need to reverse engineer it. Do you guys think it would be possible to get this published?

hello, are you still on discord, i cant find the group hot start... any invite or link by a chance ? thanks

You will need to create a support ticket for this: https://support.x-aviation.com

I am trying to log into the Xaviation site and receive prompt for 2 form factor challenge. However I am not receiving an email as the prompt advises.

Here you can see the plane is pitching up and down, idk the why. Can someone help me?

I would just like to add that the use of the adjective "broken" in connection with the current state of the 737 makes me question the validity of the other arguments that were brought forward as it made me assume that there is a fundamental misunderstanding about how this airplane works and a fruitful discussion about it´s shortcomings (that are openly and for everyone to read in this thread https://forums.x-pilot.com/forums/topic/8526-things-that-are-not-going-to-be-in-v15/ would be very difficult to have.

Hello! I built a 737 classic cockpit and connected all my devices to IXEG 737 Classic Plus model, successfully connected absolutely everything, all inputs and outputs, except... Except the IRS display on the afteroverhead. I can't find any dataref that matches the image on the screen in any of the modes. I would appreciate any form of dataref, be it just a string variable or an array of integers where each number represents its own segment on the screen. Please help. I have a completely working cockpit, except for one small but very important detail that separates me from full immersion in flight, and aircraft model accordingly from being completely finished for cockpit builders.

I appreciate you clarifying, but let’s be clear: wording like “abandoned” and “complete disregard” isn’t just “firm criticism.” It crosses into accusatory and inflammatory territory, which is why it came across as disrespectful. We welcome criticism, even strong criticism, when it’s specific, constructive, and avoids framing the team as intentionally neglectful or dismissive. There’s a meaningful difference between saying “I feel left in the dark and would like more communication” versus “this product has been abandoned and shows disregard for customers.” If you want your feedback to be heard and acted on, keep it focused on issues and expectations without personal digs. You’re free to be frustrated, but this forum will not become a place where negativity gets normalized under the banner of “honesty.” If the tone of future posts crosses into the same territory, we may need to step in through moderation.
