Yes, I've learned about this bizarre aspect of the NX.  It would be equivalent to having a car that needs to have its brakes applied to stop it from accelerating at idle. 

Hard to fathom that was actually allowed to persist in the final design.

Think of it like having a very high torque engine, it's normal for it to roll and even learn at idle. I learned manual/standard in a V6 and the leaps of torque made learning how to use a clutch much easier.

This was left in the "final design" because of how power bands work. Based an a wide variety of variables, engines of all likes have various power brands the dictates the higher end of thrust/torque/hp they can achieve and in turn the lowest amount of power it can achieve. So in order for CFM to achieve the MCT they wanted with the LEAP engines, which is pretty high to begin with, that power band needed to be moved forward, resulting in a high level of thrust even at idle. This is a huge over-simplification but hopefully it get's the point accross. It's more like a side effect of achieving high levels continuous of thrust.

I knew someone with a sports car that did that exact thing. 

Justify it as you may--it's a goofy design any vehicle that needs to wear out its brakes to keep it from accelerating is a goofy design!

Oh gee, ok sounds "normal" then 😂

I understand there's a point, I just don't endorse the set of variables necessitating braking at idle.  It's nailed me a few times or more in A Pilot's Life (monitors stages of flight for compliance to a set of criteria and scores each flight, one of which is not exceeding taxi speed of X) so I'm especially soured by this aspect.  Enough said...

I think you'll need one of these

I think this is just one of those things when it comes to flight simming, the more high fidelity aircraft you fly, if they're implemented right, you also accept the annoyances and oddities that come with the aircraft. I guess the only solace here is that, the RW pilots also have to deal with it so you're not alone.

The real NEOs have these exact same characteristics. It sounds like you are criticizing the developer for accurately modeling how the plane behaves in real life?

You're right. Maybe we should emphasize again, that we are only simulating real world behaviour.

And what Lucky tried to explain, was real world stuff (and not any sim stuff / limitations).

Ok sounds like its calibration routine will not mess w/ the MSFS default use, great, so I will run the FBW installer to update.  Thanks for that Lucky.

Yes, I've learned about this bizarre aspect of the NX.  It would be equivalent to having a car that needs to have its brakes applied to stop it from accelerating at idle.  Hard to fathom that was actually allowed to persist in the final design.  I've assigned L/R brake axis to one axis on my TM Boeing Pendulum Yoke but it's finicky to get set correctly.  My other choice is to just start one engine until close to the runway threshold.  

 

It’s the engines like on the real NEO they provide a lot of thrust even at idle, some airliners taxi to the gate with only one engine on. Also most American automatic cars I drove will go up to 10mph at idle if you don’t press the brakes 

Any update on the status RNAV, RNP and Radius to fix approaches with the proper vertical guidance component ?

Also, calibrating your throttles in the FBW EFB won't affect other planes. You simply move your throttles to where you want the detends to be and click the button. It is possible this is affecting your speed as well. It doesn't take much to get the NEOs really moving on the ground.

That said, if you are using a joystick slider, that is the path to pain. When my TCA needed a warranty repair, I ended up setting up keyboard commands for the trottle positions. SInce A/THR is kept on all the time, I just needed a keybind for a "a smidge of throttle" and the 3 detents.

OMG you are so wrong.  I simply said I don't endorse a design that requires braking at idle thrust, that's all.

10mph would be killer--but as you well know NEO keeps accelerating

the VNAV component of RNAV is still on hold until we merge in our rewrite of the custom FMS, it's currently in the 380 but not in the 320, the FMS that is. RF legs are already in the LNAV iirc.
