[@Bartonovich52]

Before GPS it was LORAN, OMEGA, and Inertial Navigation which was from about the 1960s. Before that, it was dead reckoning using a drift sight and flight computer like an E6B and making sun/star shots with a solar compass or a sextant. Errors were often significant and cumulative.. but usually good enough with the forecast upper winds from all of the weather ships to enable you to home in on a VOR or NDB which had ranges of a couple hundred miles.

[@wrightmf]

Back in 1980s I was talking with a former B17 air crew member (he never talked about combat missions), he mentioned one particular flight from mainland US to Hawaii in 1940s where the navigator wanted to make the best accurate timely arrival. Navigator constantly did observations and calculations with no breaks [I forgot to ask did he ever go pee?]. With so much work he got within one minute and one mile. I have no idea how it was normally done but I'm sure a good navigator is very essential.

[@Hopeless_and_Forlorn]

Nice job. Retired mechanic here--not many people realize that the Boeing 737-100 and -200, introduced in 1968 and 1969, had a basic but very functional fly-by-wire capability built into the SP-77 autopilot. With the autopilot engaged in control wheel steering mode (CWS), the control cable input lever on each flight control power control unit was locked at neutral and resisted any movement by the control cables. The force applied against this resistance was detected by force transducers mounted under the cockpit floor. Electrical signals from the force transducers were sent to the autopilot roll or pitch analog computers, processed with rate and angle limits, and output to the PCU servo valves to move the appropriate control surface. When the pilot force was removed, the computer either held the present bank or pitch attitude, or returned the aircraft to straight flight, depending upon sub-mode engagement. Watching the pilot fly the airplane in manual mode versus control wheel steering mode, it was normally impossible to see any difference in the pilot actions and results. By observing the autopilot engage switch paddle position, you could see whether the pilot was flying the airplane in manual, or utilizing the benefits of the electronic overseer. For its time, the Sperry SP-77/Boeing flight control system was nearly perfect.

[@binzy9659]

Great aviation vid Joe. Keep it up! Also thanks for doing my suggestion for a vid! 😁

[@lpostert]

Joe, what an amazing video. I’m an Aeronautical Engineering student at the German military university in Munich, to become a military pilot. Basically, you just summarized what we had as an introduction to instrumentation and control engineering. Our professor used to work for Airbus and therefore he took the Fly by wire-system as an example to explain how control loops work. I’m amazed that you addressed so many details in a video that is not primarily intended for engineering students. I think your content is extremely helpful for anyone seeking to deepen their knowledge in aviation and I’d be lying if I said that your educational and motivational videos hadn’t been very helpful to myself to keep on going when university gets tough. Thanks for your awesome work!

“How do you do, fellow kids?”

[@Horstroad]

12:42 McD followed with the MD11 in 1990. The MD11 was a FBW/FBC hybrid. Control wheel inputs in manual flight were transmitted digitally. Feedback was given via the cables. The elevator inputs are assisted in the neutral position. With no inputs, the elevators are automatically moved within 5° to keep the aircraft attitude stable. With the autopilot engaged, it's full FBW. The Flight Control Computers (2 pieces with 2 channels each, so four channels in total) control only one of the four actuators (four ailerons, four elevators) dependent on what channel is in control. The other three actuators of the ailerons and elevators are slaves driven by the linkages and cables that connect them all together. Theses cables and linkages also give feedback to the pilots. The 777 is full fly by wire. There are 16 position transducers on the control wheels/columns/pedals (6 for the control wheel (3 each for CM1 and CM2), 4 for the pedals (2 each for CM1 and CM2) and 6 for the column (3 each for CM1 and CM2)). They provide analog signals for the ACE (Actuator Control Electronics, 4 units) which convert these analog signals to digital. These digital signals are sent to the Primary flight computers (3 units) where they are processed with protection functions, stability augmentation and stuff like that. The processed signals are then sent back to the ACE and to the Autopilot Flight Director Computer. The ACEs convert the digital signals back to analog and send them to the control surfaces. The AFDC send the signals to the backdrive actuators on the control wheel/column/pedals for the protection functions (for example bank angle protection or tail strike protection). This is in normal manual mode. In secondary mode, when the PFC lack some information or have internal faults, some functions are not available (for example autopilot, envelope protection, thrust asymmetry compensation), but the PFC still process the digital signals and send them back to the ACE. In direct mode, when the PFC are not available at all, the ACE send the input signals straight to the control surfaces without processing. When the autopilot is active, the autopilot commands are sent from the AFDC to the PFC where they are processed and sent further to the ACE where they are converted to analog signals and sent to the control surfaces. The AFDC also send commands to the backdrive actuators on the wheels/columns/pedals for feedback. When all electronics fail, there is only pitch trim left for pitch control and two spoilers, one on either side, for roll control. These are the only actual mechanical controls left. The Control wheels/columns/pedals are mechanically linked together, so the L/H side always knows what the R/H side does and vice versa.

[@tomstravels520]

No mechanical rudder control?

[@Horstroad]

@@tomstravels520 There's no mechanical backup for the rudder on the 777. When you lose the ACEs you have only the horizontal stabilizer trim and two spoilers for attitude control.

[@tomstravels520]

@@Horstroad hmmm interesting. The A320/A330/A340 I believe have mechanical stabiliser (provided the correct 2 hydraulic systems are working) and rudder. Any other turn co-ordination is through asymmetric thrust The A380/A350 are completely different and use a Backup Control Module which is segregated from the normal system but does require a hydraulic system (Yellow only on A350) to be functioning as the power source but you can still maintain control of the THS, inboard ailerons, elevators (inboard only on A380) and rudder. It’s basically a non mechanical system

[@Digi20]

depending on the aircraft, there sometimes is limited mechanical backup most commonly for the rudder and the horizontal stabilizer. that said, if the aircraft is so damaged that all redundant electrical and digital connections fail (that would mean no engine power, no apu, no battery power, no ram air turbine...or a fire in the avionics etc.) it will most probably crash anyway regardless of the control type.

Excellent video Capt. Joe!! I am a flight controls system engineer with 30 years experience, and have certified multiple FBW FCS systems for manufacturers around the world. You did a very good job at explaining the principles and keeping it in layman’s terms (otherwise it can get very complicated and nauseating). I don’t think I could really come up with negative comment on your work :). One thing you didn’t touch on, perhaps on purpose lol, is the whole debate on who should have ultimate authority of flight safety - the system or the pilot? It may have died down somewhat now, but there used to be an argument that pilots know best and should be allowed to break the aircraft if they see fit in a situation, and there have been cases where this has proven true. I guess you somewhat touched on it in discussing force feedback in controls. Congratulations again; I’m looking forward to the next one. Cheers!!

@@francisgaliegue6645 I don't understand what you are expecting. Stall as explained by many pilots (and Gabriel Simon) is clear. What happens in the real world? The airplane simply falls down since there is no more lift. No need of equations to understand that.

[@topethermohenes7658]

I'm not 100% sure but unlike the sidestick the rudder on an airbus is mechanical. That's why it's strongly advised NOT to use the rudder in flight because you will induce an uncoordinated action. Use the rudders on the ground on landing and takeoff roll and before touchdown when correcting a crab angle approach
