First time i flew the PMDG 737 was in FS9 back in 2006 or so. Today, 16 years later, I will finally understand what CWS means. Never cared about it before. :D Thank you!! :)
haha, one always learns something new in the PMDGs! I for instance only recently discovered the clickspots on the speed brake and flap lever that allow you to move them instantly to the position where you want them (DOWN DETENT, FLT DETENT, etc.). There's always something new to discover in these planes!
@@A330Driver Wait, what? :D
@@TypicalDutchSaysHi Hahaha, I guess we're all learning new things today.
As somebody who flies FBW jets in DCS all the time, I find CWS to be pretty intuitive and its my preferred way to fly outside of CMD mode. This video was super helpful for learning the finer points of it, thank you!
"Airbus Mode" What a great way to think of this. Thank you for such great videos on this airplane.
Thank you so much for your kind words!
I like the way CWS is implemented on the Embraer 145. The control wheel has a button marked 'TCS' (touch control steering) that temporarily enables CWS if you hold it, and the autopilot maintains the attitude you set after you let it go. When any lateral or vertical modes are selected, the AP will revert to following that mode when you're not using TCS.
It's very useful to make short corrections to your flight path without having to disengage/re-engage the AP every time.
That's very similar to how trim release work on modern heli..
I can finally understand what CWS is. Thank you captain
In my aircraft (not the 737) IRL when I fly vfr I put in cws to maintain level attitude and bug 200 ft below cruise alt to reduce the autopilot randomly diving and climbing for up and down drafts, to increase general comfort and reduce pilot fatigue
I use CWS when flying pure raw data/manual sectors. Just eases the workload a little. One man in a cockpit for full raw sector is hard enough as it is.
Wow I think I might start using this now
Yeah I like hand-flying departures but this is a great way to make it a smoother experience for the passengers
So thats what that button does. Love your videos learn things I'd never learn XD
Wow after all these years I finally know what CWS is used for. Awesome video and thanks for the tutorial.
I always equated this in the Boeing to making it easier to trim and maintain like the airbus does on its own. Glad I wasn’t too far off.
Amazing Tutorial Sir , felt like I was back in my Type Rating class.
So good to see Barbados getting some love I’m from Barbados so this is going to be one of my favorite videos from you by default lol great video keep em coming
Yay! Thank you!
Oh, you flew to Barbados. I live on the island of Martinique a few kilometers to the northwest. Very good explanation by the way !
Flew to Martinique a while back with some friends, unfortunately without recording it. Next time!
Airbus mode basically lol
great video!
haha, yep ;-)
Even though colleagues do look strange at me when I refer to it as the Airbus mode at work ;-)
@@A330Driver Really? 😂 I've heard Southwest guys call it Airbus mode.
Yeah, fly-b-wire came to mind immediately
Thankyou so much Captain. Well delivered and very informative. Love your work :)
Awesome explanation, thank you Captain!
Thanks captain! Now I also finally know what CWS-R(oll) and CWS-P(itch) stands for. Also like the term “Airbus Mode” or maybe you can call it “Airbus Wannabe Mode” 😂. But still I wonder why this mode isn’t programmed in the flight computers? Especially when you only use it during severe turbulence. Can you explain? Thanks!!!
Very informative. I was wondering why I've never seen you use this mode in any previous video. 😄
Glad it was helpful!
Great video.
Although, the statement that CWS is essentially exactly what an Airbus does isn't right.
Airbus flybywire Normal law is designed to maintain aircraft trajectory, not attitude.
As an example, if you decelerate in level flight in an airbus, the aircraft will keep raising the attitude to maintain the initial trajectory. So it doesn't maintain attitude, just trajectory.
Awesome video as always! On another note, is there a release date for the -900 yet?😊
Hard to take any “release dates” seriously from pmdg until it’s less than a week out
Release date : not before 2025 (if we are optimistic of course)
Great video! 👍👍
Thank you! 👍
It is like the flybywire normal law.
Without the protections, yes.
I think in the 737-200 CWS was the primary autopilot mode, atleast in the old pre 200adv of the Tinmouse Add On for FS9.
It is. That's the SP-77 for you. The autopilot can managed the lateral mode fully automatically but the only pitch can do automatically is to hold the altitude. You have to use cws for climb and descent. Only few got the new SP-177 (production 1982 and above) which has full automation capability, new autothrottle, and autoland capable.
Thank you sir for the very informative video.
😄❤💙💜
Always welcome
Thanks!
i never knew that, thanks
Thanks Emi.. learned something again today. Could you possibly do a future video on the stabilizer trim switches ? At the bottom of the pedastil there's a guarded switch for norm or override. And just below the flap lever there's more switches related to that. Im asking because I want to disengage all the automatic trim when making a real manual approach..
There is no automatic trim with autopilot off, it's all done by the switches on the yoke
Those switches only select which drive motor is used for the stabilizer trim. With all of them off, you are going to have to crank the huge wheel on the side of the pedestal by hand.
@Stoney3K ah I see. Thank you !
@@tomstravels520In fact, there is. It’s called the STS, and it engages if these conditions are met:
Airspeed between 100 KIAS and Mach 0.5
10 seconds after takeoff
5 seconds following release of trim switches
Autopilot not engaged
Sensing of trim requirement
CWS is just airbus normal law isn't it
Edit: Yeah he confirmed it
Airbus normal law minus the protections however. It holds pitch and bank.
Because it doesn't have the protections, it's more like alternate law.
When deploying the flaps, is the aircraft pitching up or down ? and why?
And when the aircraft is losing speed why does it pitch down ?
Deploying flaps should make the airplane pitch up due to increasing lift. But since extending flaps will also move the center of pressure to the back, the nose of the aircraft will be lower than when on level flight.
Does the Longitude in MFS have CWS? It is modelled on the left seat yoke left side. Is there a key binding in control options?
AKA, "Airbus Mode"
Why can’t I turn the pmdg on the ground??
How come on my 737 the hours til next maintainance always resets automatically after each start? Eg, I end a flight and it tells me 200 hours til next maintenance. Then after i end the flight and load up again, it says 225 hours.. any ideas?
I think you have to enable service based failures for this to tick down and actually have consequences ? Also there are some other options like oil and hydraulic levels staying or resetting, all in the fmc options menu. Manual has it all explained in the beginning i think.
@@vedymin1 The service based failures are enabled. It always jumps back to the standard hours. I’ll check the other videos 👍
What field is this?
I'm fairly certain it's BGI (ICAO: TBPB)
Exactly as wiskwise99 says, it's Bridgetown, Barbados, TBPB.
Which airline do you fly for? :D
Ryanair iirc
I will neither confirm nor deny ;-)
Aeroflot. His accent is russian af
@@a.nelprober4971 you are going to be shocked when you discover Germans then....
Emi is not Russian. Lol.
@@a.nelprober4971 what are you talking about his accent is not even close to Russian haha. It is 100% German
