Avionics systems engineer here (Electrical Engineering degree from Embry-Riddle, class 2006). I absolutely came here because flight control avionics is absolutely where I've spent most of my career. Commercial instead of DoD, but still, I love Flight Controls 😁
Jello, this was one of the absolute best fighter pilot podcasts you've published! Man, this was a fun one! From a pilots POV, this was fun to learn about because this isn't a subject that's typically in a pilots wheelhouse... at least at this level of mastery! Good times!
I found your title to be very interesting. My dad was an electrical engineer and was the project engineer for the direction and planning of the F-18 flight control test stand for Northrop in the 1970s. This included hardware selection, software development, data acquisition system, data processing, instrumentation, and test control Consol design. He was also the liaison between McDonald Douglas control engineers and Northrup Test Laboratories. That’s directly from his résumé. So to me this was all very interesting. This podcast brought back a lot of memories of things dad used to talk about. He passed away 35 years ago, so I haven’t heard a lot of this in a very long time.
I spent 32 years working software in digital flight control systems development; what a great episode, bringing back a lot of great memories. Worked the AFTI/GCAS software design back in '89-'91; loved the 12 minute trailer for the next podcast!!! Thanks, Jello!!
I watched a lecture on the F22 flight control systems, and I was blown away...thanks to all of our warriors who put their lives on the line on a daily basis...I now understand, almost, your enthusiasm for flying these...these....miracles of aviation...
I was so excited to listen!! Moving into more advanced aircraft as a civilian pilot means have more Fly By Wire systems and this episode is great for a baseline!
Idk about y’all but fcs’ are really cool to me. What i love is how they can have different modes in different flight regimes and how fly by wire can also independently move surfaces to enhance overall maneuverability
Listening here with great interest. A "few" years ago, I was fascinated to learn that the F-16 was using fly-by-wire to enable the airplane to fly with relaxed stability. Now I like to joke that my Piper Cub also uses fly-by-wire =)
Absolutely love it! Please bring more of such stuff: control surfaces, wing configurations, planforms, tail assembly and fuselage types, engines - I want to hear about everything!
Only new to the channel since the whole TGM thing. Have been waiting for a new episode, as they’ve all been wonderful, and wondering when one would pop up 👍
1. Funny intro, Jell-O! 2. Interesting subject, I learned something new. 3. I am happy to hear the Tomcast drive went Over-the-Fence instead of breaking even or falling short. Stay Blessed, Fly Safe!
Hahah, funny intro, yes I definitely picked this video on purpose! But actually, quick question about your previous Top Gun podcasts. I noticed like I’m sure you guys did, that they used the old style helmets in the movie. I assumed it’s to see the actors better but I don’t think I heard you guys address it? Thanks for all the great content! Loving it
Yes, I covered that in one of our trailer breakdowns: the joint helmet mounted cueing system only comes in tinted visors, which would not be conducive to seeing actors’ faces.
Let’s face it….. The JHMCS ISN’T exactly photogenic. Functional ?: Yes Futuristic?: Yes Vaguely insectoid?: You betcha Hollywood good looks?: Not so much
I became aware of’Fly by Wire’ back with Corp aviation. In 1990 our Corp pilots preferred the old G-2 flight systems and were trying to get used to the new Bombiare (Sp?) wide body Canada air plane
We've been hardening critical electronics from EMP ever since we discovered the phenomenon in the atmospheric nuke tests. The latest generation of DFLCS is fly-by-light and power-by-wire with ElecyroHydrostatic Actuators (EHA). EHAs are a godsend for maintainability and simplicity of design.
@@FighterPilotPodcast He talks about EHAs at 1:00:25 on F-35. On F-16, if mx personnel discover one of the hydraulic actuators on an elevon is faulty, it's a long process to replace and re-calibrate. They have to drain the hydraulic fluid from the redundant lines, disconnect the hydraulic couplings to the actuator, unfasten the linkages, unfasten the mounting points and connections, then remove the actuator. Re-install in reverse order, purge and re-fill the hydraulic lines, pressurize the lines, top-off the lines, then calibrate and index the control surface with the actuator position relative to the CLAWs in the DFLCS. On F-35, if the EHA needs replacement, all its fluids are self-contained. You remove the fasteners, pull the unit, re-intall the replacement EHA, which the DFLCS auto-recalibrates, done. This is one reason why even the most complex STOVL JSF-B variant has roughly half the MMH/FH of the F-16, and the Viper has been the gold standard in Radar-equipped single engine fighter maintainability over the past 45 years. F-35A MMHPFH has been 4.1-5.9hrs, depending on year. F-35B is 6-9hrs F-35C 5.9-9hrs F-16: 11-14hrs, not including ECM, FLIR, HTS pods
My understanding is that MCAS was developed, not to get the most performance out of the airframe, but to make the MAX handle similarly to the previous generation to avoid the airlines having to spend time and money training and certifying pilots on a new aircraft type. One issue they were addressing was the difference in pitch up on acceleration caused by more powerful engines.
This is correct but it goes farther. Pilots can easily be trained to handle a change like this. Which was due to more powerful engines, that were larger diameter and had their thrust axis even lower than the CG than original. Boeing was concerned the FAA would require an entirely new type-certificate. Which is a multi-billion dollar proposal, for an already established and near retirement airframe. The type-certificate specifies the stability and control perameters of any given aircraft type. Because Boeing determined their modification probably wouldn't meet that criteria and would botch the whole program, they opted to hide the issue with new control-laws and systems. But because it was "secret" what they were doing to work around burdensome requirements, they did not have the resources of the whole company involved. So, it that departments infinite wisdom, they granted a non-redundant and failure prone AoA vane sensor the authority to apply nose down input against what the pilot was attempting to do.
@@Triple_J.1 Yes, the training for pilots is relatively straight forward, but if not for MCAS, Boeing was faced with the new aircraft having a new type designation from the FAA. This would have meant additional testing and approvals before the aircraft could enter service. It would have been expensive for the airlines to send the pilots for type training on the new aircraft. Boeing wanted to avoid this and the ensuing delays as it would decrease the attractiveness of the new aircraft to the airlines and made the Airbus competition more competitive.
Re: Ham Std Prop As a young engineer i saw a movie about making the props. What was amazing was seeing the steel tube being extruded when at yellow heat.
Regarding Snodgrass, normalization of deviance is a killer. SOPs exist for good reason. Given how that lock is installed and not immediately obvious without a checklist, I'd place one or two RBF streamers on it and tie one end to the stick or with a bag over the top of the stick.
Greetings from Germany ✌I'm not a real Pilot, but I fly model Aircraft as a hobby. So it is completly fly by wifi. Still, today in my model aircraft, we get more and more flight assisting systems, like gyros, bank angle limiters, panic recovery functions and even auto pilot. Me personaly I like a good stabilisation system, it is amazing how it can change a crap flying plane into a docile flyable one. However I do prefer an airframe that flys good by design. Electronics are essential for mosdern aircraft. But I wonder by my experiance: How often do pilots and electronics collide? Even in my car I hate those systems, because they never anticipate what I want to do and sometimes even limit or endanger my driving severly.
Quick question for you guys: In TOP GUN: Maverick, we see lots of flares being used to avoid missiles during the battle scenes, but in the original TOP GUN, during the final battle, no one uses any flares and can only try to out maneuver it. In "Maverick" its shown that the F-14A has flares which would mean that they would have had it for the original. My question is why wasn't it shown in the original? Thanks!
I’m confused about the response to the RUclips interactions to this episode. Fewer views than I’d expect but the ratio of thumbs up and comments to the number of views, seems way off. Too few
So sad that you heard from people complaining about a guest’s political affiliation and your sponsorship by a particular network. Part of the degradation of values you mentioned is the lack of too many people to be considerate of others’ views, or realizing that business is just that, and does not necessarily proclaim an endorsement. Keep up the good work anyway, and you are winning!
Dems and Repubs both fund the military, both have congress members who select generals and admirals, both sides vote on military sending bills, and both elect commander in chiefs, and both serve in the military, and each have property and values that are protected by the military. Both sides enjoy freedom. The left weights 1A speech that the right seems to dislike. The right supports 2A guns, the left dislikes. At the end of the day, open your eyes. Its not one or the other. In fact, both sides are wrong in some areas. Such as supporting the draft and refusing to outlaw it. What is the point of fighting for freedom if you are not even free to not fight? Smh. Its the antithesis of American values and the right to life, liberty, and the pursuit of happiness. I don't understand partisanship when it comes to Military. It doesn't make sense. Both sides need a come to jesus about what this country stood for and should stand for. Liberty and Justice for all.
Analog is extremely limited as it relies on the human operator to control, supply motor effort, and maximize performance throughout the envelope. No matter weapon or fuel stores including asymmetry. Quadruple redundant fly-by-wire is the gold standard and has been for over 50 years. Even the newest commercial airliners and even corporate jets utilize these systems to great effect. But these old Harley guys cant figure out why anyone would want a fuel injector and ECM over a carburetor and magneto. And they are happy as clams topping out at 107mph getting barely 28mpg when not overheating in traffic.
@@Triple_J.1 harley riders aren't going to come up against 6th gen weaponry.... I didn't want to say your fly by wire could be turned into a big rock really quickly but now that I've said it I hope you get it now. You want to be impervious to the electron beam... And the only reason you need fly by wire in the first place is because they make the birds unflyable in the first place chasing pointless envolopes when no human can sustain 10g's. Analog controls with state of the art offensive and defensive ordinance.
