How Flight Controls Work | Part 10 : Pitch Control

Note: This video is not an accurate representation of the real flight situation.
To facilitate understanding and visualization, I have used exaggerated animation and maximum control surface deflection values.
Aircraft systems explained.
* Primary flight control system.
* Pitch trim system.
* Manual and Autopilot pitch control.
* Alternate pitch trim system.
Major components covered.
* Primary flight computer and software's (stall protection, tail strike protection, overspeed protection, Autoslat, elevator feel force, stabilizer runaway protection, column cutout, elevator offload function, speed stability and static stability augmentation)
* flap slat electronics unit and Autopilot computer.
* Control column, elevator feel unit, pitch trim switch, trimmable horizontal stabilizer and elevator.
* Wings, Speed brakes, Flaps and slats.
Software's used for making the video.
* Blender 3.0 and Filmora 10.
Background music used in the video.
* Teardrop Sky (Filmora stock library).

THANK YOU, Aircraft Science! Your videos help to better understand and fly the B777. Can’t be grateful enough for your amazing work.

Great to hear!

That series was great, now one on the Airbus equivalent

[@CoasterGuy787]

Awesome 777 series of videos. One thing I'd like to mention. Concerning the stall protection, the fly by wire system will eventually prohibit manual nose up trimming of the horizontal stabilizer as the aircraft gets closer to the stall and as airspeeds gets too low. The system will fight to avoid a stall but the pilot has the ultimate authority, since it's a soft protection. The pilot will be able to stall it if he applies enough back pressure to force the 777 to stall after the trim is inhibited.

Great point!

[@hutmitfrosch3030]

As it should be. Other than the Max' MCAS ... :p

[@CoasterGuy787]

@@hutmitfrosch3030 Yes, as it should. The pilot having the ultimate authority of control , excluding how MCAS was previously on the 737 Max.

[@hutmitfrosch3030]

@@CoasterGuy787 True. That's what I meant by my comment :-)

Neat finale in the 777 Flight Control series. Was interested in what the Boeing FBW equivalent for the Airbus FBW Alpha Floor is, this seems to have answered it extensively. Also, was great that you went into some detail on the -300ER's tail strike protection software.

How do you attain CG%?

[@AircraftScience]

The pilot will enter the CG value into the aircraft computer before departure.

[@demal1010]

@@AircraftScience I mean where do you get the value? Is given by a computer or something you have to figure out yourself?

[@AircraftScience]

It's part of the weight and balance procedure, calculated by the pilot or the cargo department personnel.

What's coming next?

[@AircraftScience]

The next major series will be on the auxiliary power unit.
