Yep same in the 787. Hence speed control is so important here.

@Blackbox711 I heard that some airlines write in their SOP that AT has to be on during landing. What are your thoughts about this and what does your airline say?

That I found out today 😁

It really was 👍🏼

Hi. Taking your example: lets say you are flying manual and trimmed nicely for 250 kts, flying at 3 degree pitch. Then you want to climb at a pitch of 6 degrees. You would pull on the yoke and put in a 6 degree pitch value and manually (or autothrust) add thrust to maintain the 250 kts. Then no pitch trim input would be needed as the FBW would do its thing to maintain the pitch. The principle of the FBW system is mainly to help stabilize the aircraft and to keep it within its flight envelope. Boeing has a slightly different design compared to Airbus where the automatic pitch trim does not include speed changes in manual flight. Airbus on the other hand does this too.

@@Blackbox711 Ok so you’re saying that if I did the same thing in the 737 I would have to re-trim as I changed from 3 to 6 degrees whereas in the 777 that’s not required.

@@speedbird8326 a pitch increase changes several aerodynamic factors. The 777 adusts those in manual flight apart from a speed change trim requirement. In a 737 there will be a trim requirement already for the thrust increase. So yes, in manual flight the 737 will need more trimming.

@@Blackbox711 Ok thanks for the explanation.

Thank you very much

Hi. No it isn’t. That is completely seperate and takes the target speed value (magenta pointer on the speed scale).

And yes, it is allowed to fly with autothrust off

Thank you Mark 🧑‍✈️✈️

Thank you for watching and your kind comment

The FBW speed trim reference should be put to the speed you want to fly. So if the speed deviated from reference speed and you want to return to it then don’t change the trim.

Vielen Dank für das nette Feedback ✈️🙏

Hey. Thank you! With a force feedback yoke it should be as you wrote, there should be no control forces when the actual airspeed is at the indicated trim reference speed. The challenge comes with airspeed changes. An instructor will tell you to correct first with yoke input and then trim away the pressure. However here as you wrote you would do this in tandem just like in an conventional aircraft. The more you practice the more intuitive it becomes. Btw. I had to order the FF Brunner after watching you fly with it. Happy Landings ✈️

@@Blackbox711 thank you that helps! Oh wow thats awesome I cant wait for you to get it so you can make even better profiles! lol the software takes a minute to get used too, and its not perfect, however once you go FFB there is simply no going back. Cant wait to hear what you think about it!

Could very well be. It is not described in much detail on how and when the FBW system uses elevators and stabilizer position. If you find a good reference I would love to hear where I can find that.

There are quite a few checks to prevent the FBW from flying the airplane with the tail plane.Can’t remember how Boeing did it, but checking the column position OR checking the rate of elevator deflection can both rule out the transient motion.

I saw that too and can only imagine low animation quality

Thank you for watching

Deicing/Antiicing with fluids is only done when you have frost or snow on the aircraft. The engine anti ice is used whenever temperature is below +10 degrees Celsius and visible moisture like fog/clouds or contamination on taxiways. ruclips.net/video/llFXWfjju84/видео.htmlsi=_5W0e4xFHE3zKftn

@@Blackbox711 thanks captain

😂 all for entertainment purposes. Will be interesting to try in the future with a Shared Cockpit Setup.

@@Blackbox711 Okay I'll be passenger then 🤣

Hopefully the price will come down 😜

Thank you 🙏

Problem is that the FF777 V2 is far from finished. But if it is developed fully then I see it being overall a great competitor to the PMDG 777

@@Blackbox711 thanks I mean I just think the 777 from pmdg is missing some tweaks there and there. I also think they should add some cool visuals like FF does and also I think msfs 2024 will provide overall better flight physics to aircraft cause one engine operations on a heavy plane seems underwhelmingly bad

@@RAVIOLIdS Big expectations are on MSFS2024 regarding aerodynamic simulation. I really hope that they will deliver.

@@Blackbox711 me too captain thanks for you content btw I love it and its super informative

Thank you for watching. The huge amount of interest and questions was a handful to handle. Hopefully most questions were answered.

the 777 has automatic rudder trim during engine failure

Normally the aircraft would yaw towards the dead engine. There is indeed a Thrust Asymmetry Compensation. On top of that my initial rudder input may have been too strong.

Although the ATM takeoff thrust setting is not considered a takeoff operating limit, the selected fixed derate is still considered a takeoff operating limit. This is because takeoff speeds consider VMCG and VMCA only at the fixed derate level of thrust. If an engine failure occurs during takeoff, any thrust increase beyond the fixed derate limit could result in loss of directional control and should not be accomplished unless in the opinion of the captain, terrain clearance cannot be assured. If an engine failure occurs during takeoff when using both the reduced thrust (ATM) and fixed derate methods, Boeing recommends that the thrust levers not be advanced. This is because the fixed derate limit is not displayed on engine or flight instruments.

I don’t own a 777 FCOM but a 787 one. So if the 777 allows for thrust increase in Derate + ATM takeoffs, then it is different to the 787 procedure. Up to now I only fly the 787. And my FCOM is clear on this as you can see.

@@Blackbox711 wow..! Pretty different philosophies then! Thanks for the input about the 787 on this!

@@MurphyJungKRI appreciate your feedback. Good to know the 777 isn’t as restrictive regarding thrust increase ✈️

Thank you 🙏

Yes, many

😅 I am actually German. But lived in England for 5 years.

@@Blackbox711 Ah I see, I was well off then 😂

Nope, it’s PMDG. Flight Factor, if I am not mistaken, is an add-on for X-Plane, meanwhile PMDG is for Microsoft Flight Simulator 2020.

@@zaviationn Just look that 'X-system' on the top left corner.

@@ati4280are you a robot

@@user-qc8np2sw8h are u doing Turing test?

@@ati4280The first part of the video is PMDG, I guess Flight Factor is a bonus.

Thank you very much 😎✈️

@Blackbox711 no problem, just found out that you can use the fixed config option in the aircraft equipment page to automate this process :)

That is unfortunately more in the responsibility of MSFS/Asobo. Hopefully MSFS2024 will improve this.

@@Blackbox711 yes fingers crossed. Im sure aircraft developers are hoping for physics improvements more than we are. less work arounds

I turned down the volume of those announcements after a few minutes into the stream.

Thank you very much!

I doubt it

Why are you sad? It will get updates and fixes for months after initial release like the 737 did.

@@AtomSmash3r sounds like a toyota prius

Yay, let's hope they can sneak the fix in by launch day.

2:47:41 Isn't the pitch up/down moment simply a response to adding/decreasing thrust? Maybe the reaction is overpowered because the engines are spooling up/down too rapidly?

And yet again another broken FBW logic! Was broken in P3D all the time, as 777-rated Pilots repeatedly testified over an extensive time period on the PMDG Forum. Hard to believe that they ever had a chance to fly a Level-D Fullflight Simulator, as they claim in their introduction manual… And very odd that this ( major ) issue has been identified last minute and only by a youtubers feedback… What‘s going on during beta-testing? BTW: you know that the FBW-Speedbug is not implemented in the real Aircraft? It‘s a fictional indication.

@@ClouDAction. The FBW system is based on C*U. That means there is something called "Speed Stability". When the current Airspeed equals the Speed Trim setting (the blue FBW indication on the PFD) the aircraft maintains the pitch automatically, even in manual flight. The pitch will only change when the airspeed differs from the set Speed Trim setting. Any other changes like Flaps, Gear, Speedbrakes and even Thrust will not change the pitch. That is the design of the B777 Fly-By-Wire system and makes it so stable to fly.

Also Mr.Kok from PMDG wrote me a message saying the developers have found the bug causing this pitch down and are fixing it asap.

Hey

Hi. Flow Pro is made by Parallel42. Our widget is free and available in our discord channel under Flightsim-Help Channel.

@@Blackbox711 Thanks for your quick reply!

Very welcome. Let me know if you need further help. Happy Landings

yep!!

Lots of people are not happy with the sounds. Best to let the devs know directly in their forum.

Lots of people are expressing disappointment regarding sounds.

Yep, issue has been there in P3D too
