Pretty impressive model. I love the flushing toilet.

I now realize I am too lazy to fly a plane without autothrottles.

 

In the P3D era, I bought this hardware to properly fly this aircraft. Today, I am anxious, waiting for the day to be able to use it in MSFS. Fingers crossed.

Problem is I can't find cruise control table for Q400.

For FJS 727 and 732, after applying  fmolinaresr's performance mod, I can easily set given EPR in the CC table and forget at cruise, same with Bae146 (although only RJ100's table, but works quite well in different old 146s), DC8 and Dassult Mercure(in P3D).

However if seems Bombardier are quite secure on their performance data, I still can't find the table for both Q400 and CRJs to ease my work.

That would be helpful!!!

Do this: Climb to your desired cruising altitude. Accelerate to the desired cruising speed. Now reduce thrust/throttle until the acceleration becomes 0. Done.

How much was this? That's a nice piece of kit!!

And if you write it down, you'll have a table after just a couple flights 😁

You forgot "alternate between overspeed siren and stall horn because an aircraft does not react instantly to changes in power and you do not have a feeling for adequate cruise power at your current weight, altitude and speed yet", which is EXACTLY where a cruise chart comes into play.

And knowing you, you certainly have fitted your 748 with an accelerometer on the glare shield just to show your green F/O that REAL pilots do not need autothrottle, not even on a 10 hour redeye. 😉

No, I did not. 

The cruise speed regime is stable for most aircraft, i.e. the plane will stabilize at a speed corresponding to it´s powersetting.

If you are an exceptionally bad pilot, yes, you may have trouble handling the thrust levers to approximately find the speed and you may go into the too slow (instable, behind the power curve) or too fast (overspeed) regime 😉

For those challenged in observing the thrust indication instruments and/or speed indication, Laminar has provided on-screen data readouts (activated by using the DATA OUTPUT) that will indicate very accurately not only the speeds and thrust, but also the drag and it is (at least for me) entirely too easy to immediately balance thrust and drag to achieve a near zero acceleration. Which you can also put out to screen, if desired 😉

A "cruise table" for a given aircraft in the POH is nothing but a very crude collection of data points to give you an approximate idea of the powersetting required, but will never provide a highly accurate value that is correct for your current (and always varying) condition. It gives you a ballpark to start in.

This hardware is aimed at customers of constant use such as in Fixed-based trainers, hence its price is high. In my case, the owner of the company is a very good friend and gave me a significant discount. I leave you a link so you can review it more slowly.

Hi Jan,

from your experience, how accurate are performance tables for airliners in real life? 99%? 90%?

I assume each aircraft is a bit different from the other, e.g. engines can be brand new or "worn out", etc. I wonder how much those factors can move the performance away from the theoretical data tables. In addition to, as you mentioned, all the other variations like external conditions, etc.

This is exactly what my comment was aiming at in an exaggerated fashion. A cruise chart provides a starting point for fine tuning to decrease set point trial & error.

 

Is there a data output for aircraft axis accelerations?

Edited June 4, 2025Jun 4 by Bjoern

Real performance charts only offer a starting point - especially since so many parameters influence performance and you will have to interpolate wildly...and then all aircraft differ a bit from the "standard" performance values, often by a few percent.

In X-Plane there are no DATA OUTPUT displays for linear accelerations (only angular accelerations), but you might find them when using dataref editor.

I use the SPEEDS display together with the "engine thrust" and "lift and drag" display, that way I can balance thrust and drag easily and also see any change in the speeds very easily - much better than just looking at the IAS indicator.

Thank you for this video! First video where I can clearly hear the sounds of the addon. They did a pretty good job. All the videos and streams with this addon, the audio is so faint, I never could paint the picture how is the quality of their sound package.

Why you don't use the quadrant in X-Plane with Q400? Just curious. 🙂

Hi Pe11e, I've thought about it, but I don't have the time, desire or effort to get involved with another simulator, I've decided to focus on the MSFS and its future versions as my main flight simulator. 🙂
