Hi. I flew the Hurricane, Spitfire and Me-109 as a test pilot and airshow pilot. I have a few comments: You mention the omission of cockpit heaters as an oversight, since they were not needed in earlier open-cockpit designs. I think that misses the point. Optional devices, such as heaters, were omitted due to weight, cost and complexity. A wise airplane designer once said that he throws all of the optional parts into the air, and those that come down are too heavy. The undercarriage control is a perfect example. The Hurri and Spit designs require the pilot to change hands immediately after takeoff to retract the undercarriage. A modern test pilot thinks, "Dumb design!" Remove the cowling, and the designer's thinking becomes clearer. The hydraulic pump is on the lower, right, aft part of the Merlin. The shortest, lightest, cheapest, and easiest-to-build solution is to run the hydraulics straight aft into the cockpit. The pilot's job wasn't made easier, but the fighter was made incrementally lighter. Lighter = better, even if the pilot's job is harder. That IS ergonomics in the 1930's. Likewise, tailwheel locks; best left out of the design unless the aeroplane needs it. The Spit and Hurry don't by virtue of their CG location with regard to the wheels. The Bf-109 had a comparatively VERY heavy tailwheel load. Omitting a tailwheel lock was not an option, so it justified the weight/cost/complexity. Speaking of which, the Bf-109s tailwheel lock is a great example of a bad idea; situated on the left canopy rail where movement of the throttle will cause one's forearm to accidentally dislodge it. (Ask me how I know!) The inherent ergonomic limitations of operating systems on these fighters represent the 1930's state of the art. A similar example of human factors is cockpit field of view. The Spit was utterly blind for takeoff and landing . The Hurri was better, with the cockpit raised up high on the fuselage. Was this an ergonomic decision? Nope. The Hurricane pilot sits higher to allow for a better depression angle over the nose for deflection shooting. The benefits for takeoff and landing were incidental. The design thinking was to use EVERY BIT of the pilot's ability if it made the airplane an ounce lighter. So much to say...Great video!

I locked up 2 MiG-21s that were comimg in fast, already pretty close and fired an AMRAAM at each one and then broke to try and stay out of the merge. As I turned around I started hearing their weird noise and my HUD symbology changed and I was like, "WTF am I out of AMRAAMs?" Yes. Yes I was. I can't even keep track of that with a little blip in front on me that says 3MRM, 2MRM, 1MRM. I ended up turning back around, locking the last MiG with my 9X, but it went after flares and I ended up merged. Let's just say I haven't mastered keeping visual contact with bandits (or really anything if I'm honest) and while I was looking for the guy, I flew into the side of a hill.

Ammo counters in aircraft are one those funny little things, which became so basic that nobody ask why they are there, but when it comes to someone's favourite plane lacking them, then it's suddenly unnecessary waste of space.

It's lacklustre high altitude performance was never really sorted though, until the Dora 9 which was too late to make a difference.

About the spitfire, I’ve never talked to or heard a British person talk of the spitfire like it didn’t descend from heaven.

Eric Brown noted in one of his books that the birdcage noses on German bombers were not only optically poor with lots of distortion from the curved plexiglass they also had a nasty tendency to fog. I'm pretty sure it was in wings of the Luftwaffe but I don't remember which chapter. In any case a blurry or foggy windscreen isn't just an inconvenience it also takes a psychological toll. Humans are visually oriented and blurry windows are both maddening and distracting. A foggy windshield drives me nuts when I'm driving a car; I can't imagine flying a plane with a fogged windscreen is any less annoying.

Wow, thanks sadwings. I really do appreciate that contribution and your comment as well.

As an engineer, ergonomics is always on my mind. Attention to detail is key. Two engineers can design similar things, and people will know one engineer is better, but not be sure why exactly. The difference will be in the engineer who paid close attention to details and just an all around better refined design. Aircraft ergonomics is one of these examples. Some engineers get it and do a great job, most do not. I also experienced this in combat with other vehicles. When strapped in, we couldn't reach half the switches on the dash, and so we'd have to ride around not strapped in. whoever designed that dash needed to be fired, there was no excuse for such a massive flaw. We were constantly modifying our vehicles to work better and be practical. I helped give feedback to many companies regarding their equipment and its many flaws. Some engineers take the feedback well and improve their product, others take offense and refuse to fix their mistakes. If you're an engineer, don't be the latter. Welcome feedback from people who actually rely upon what you design. I'm glad you're covering such factors in aircraft.

I'm having an absolutely fantastic day. I got started paying attention to Human Factors / Ergonomics a bunch of years ago when trying to design and build decent work station areas for multiple computers with multiple monitors. The best references that I've found have been NASA and of course the Human Factors Statistical data. I've run into several instances where the design started not with where is the bet position for accessibility for, pardon the expression, altitude challenged personnel, but with where is it easiest to install this required device. Often the relocation of the switch from 7 feet above the deck to a better location is non-trivial, requiring outside assistance to run new wiring. Other times it merely requires a bit of outside the box thinking. I think that of all the designers of the era, Kurt Tank, was the one who never forgot what it was like to be in the air in the middle of an emergency and worked hard to ensure that the emergency order of operations was simplified. As Juan Browne is fond of saying: Aviate, Navigate, Communicate. Thanks for a great series on ergonomics and design.

For many years I was a computer consultant and you might think the ergonomics is not that important, you would be wrong. putting entry field out of order confuses the entry clerk and leads to mistakes. putting the button that you want a person choose in the wrong place can really screw things up when they press the wrong button. These are just two examples in office situations that can lead to disasters. I remember looking at the report of the reasons for the Three Mile Island Nuclear Disaster and one of there main points was the design of the control boards making it difficult for the operators to fiqure out what was going wrong.

The US navy's standardisation of instrument layout made a huge change in reducing.training. Most cockpits looked like someone loaded.A shotgun with instruments, and fired at the panel

Really cool and agree on the Hurricanes compass it’s a bugger to use in flight! However I disagree on the brakes I find them quite easy to use and very much like the chippy! Also the undercarriage and flap mixer box is so easy however to a modern day pilot they would not understand it or why! Transitions from the throttle to the gear up is easy and no problem even if you forget the safety catch it’s easy just has to be done before about 110 mph otherwise the aerodynamic load on the gear doors may not allow them retract! Just my observations from flying a MK1 👍👍

I’d like to see a similar episode on Japanese aircraft. Thanks for another great show!

This is PURE GOLD. Noone mentions these factors although they did play a major role.

What an insightful presentation on an under-discussed topic, I hope you continue to expand this series!

I'm with you here. Human Factors in aircraft design can be quite fascinating. I'd like to see Greg cover HF from a maintainability perspective.

12:40 "Easily offended by facts " hahaha. Good line, I'm going to use that next chance I get.

I’d imagine cockpit heating was seen as having significant drawbacks. If done with a heater core, as in cars, it would add another failure point for the engine cooling system. If done with ducted hot air, it would compromise the firewall and add to the chances of CO in the cockpit. It’s just unbelievable that the Germans were able to fly daylight fighters on the Wilde Sau missions against the night bombing raids. They certainly weren’t notably successful, but the sheer courage and skill required boggle the mind.

My father had quite a few hours in the Spit MkIX and would completely agree with your assessment of the pneumatic brakes. Another problematic factor with pneumatics were any leaks in the system due to wear or battle damage meant a landing with no brakes. I know that you didn’t go into the 109, but my father was terribly disappointed when he had an opportunity to fly the Buchon. During the cockpit checkout it came to his attention that the canopy could not be closed with his 6’2” frame in the cockpit even without a seat pack on! The 109 cockpit is like being wedged into a F1 racer- I don’t know how anyone got out of it if it was out of control.

@ky7299

I think I saw somewhere that the Germans had devised a specific way of bailing out of the 109 which involved grabbing hold of handles installed for this purpose, crawling out of the cockpit to the left side and pushing your body downwards from the side of the fuselage to avoid being hit by the horizontal stabilizer struts of the early models. Of course this required that your arms and hands weren't too badly injured.

Another great documentary, thanks Greg. Between you and Chris over at Military Aviation History I think I have learned more about the engineering and operation of historic aircraft then I did in the previous 40 years. This is YT at its best IMHO.

Pilots blacking out due to high G is a pretty fundamental aspect of 'human factors' & where the pilot's legs go is a major factor where inflatable trousers are absent.

Kurt Tank was apparently a pretty good pilot, and an electrical enginer, so it's no surprise that he put in these human factors to ease the work load. Cheers from the Pacific West Coast of Canada.

I'd love to see a series on this for the more common twin engine planes - Mosquito, Bf110, P-38, maybe even a Ki-102? More cockpit space, double the engines and fuel tanks compared to regular fighters, often a second (or even third!) crewmember to split workload and controls with. Would certainly be an interesting watch.

Thanks Greg. Your 190 video blew my mind before. I need to revisit the the prop video too! Gotta brush up on constant speed.🐿

Thanks for another superb video. One thing that I don't think anyone mention at all, that I think should be included into human factors consideration, is the colours of instrument panels. Not that there are any one design that is superior to all, but if the panels are in contrasting colours to the instruments, it's easier to locate them with the smallest glance. If they are in similar colours to the gauges, I personally feel it is more difficult to locate them by glance, but easier to identify what gauges are showing what information. Also, though I cannot empirically prove, I feel that an another human factors win for German seating position is the relative ease of manipulating side or wall-mounted controls. I felt it incredibly strong when I climbed onto the cockpit of a Meteor F.8 from Midlands Air Museum. Once I sat inside, I could not really comfortably operate (or even see) the controls on the sides. When we design automobiles, we usually use percentile models not just for checking whether they fit inside the vehicle, but for checking if there are any controls that are technically within reach, but is not intuitive to manipulate. When I am seating lower and my legs stretched further forward, my upper body seems generally better relaxed, including the shoulders. Anyone who's been inside a really low-slung car, like an Elise or most McLaren stuffs, would (hopefully) know what I am talking about. Also, I'd suggest, of all the planes that were developed during the war and/or numerically close to, or is, irrelevant in WW2, the de Havilland Hornet would be among the best out there.

Then how B-17’s and Lancasters would compare. I’m thinking back on your PBY Catalina video now and how a flight engineer position, or lack there of would impact Crew Resource Management (though I’m fully aware CRE wasn’t a thing for decades to come). I gotta imagine a B-29 had a much more crew friendly layout vs. a Do-17, Me-323, Vickers Wellington, He-177(maybe poor gauges/placement made its engine fire problems worse).

This weekend I learned that part of the reason that B-17 bombers were more accurate than B-24's in hitting their designated targets was a direct result of human engineering. The switch that allowed B-17 bombardiers to toggle their bomb load, dropping bombs individually in a timed sequence, walking their way across the target, was much easier to reach than the equivalent switch in the B-24. As a result, more B-24 bomb loads were dropped in salvo, or all at once, which made for an all-or-nothing result.

It's easier to feel a part of your aircraft (as any pilot should) when your cockpit is designed with you in mind.

Let's not forget the size of the cockpit. I am literally not allowed to sit in the cockpit of a Spitfire, because at 6'2" I am too tall to fit. My grandfather was rejected by the RAF as a pilot for being too short. (And also for being unwilling to be ordered around and unable to walk in a straight line. They found other uses for him.)

The ammunition counters on the german and Italian aircraft were timed off the guns as they recoiled. When the guns were reloaded, the crew zeroed the counters so that they corresponded to full ammo tanks. Even half filling a tank got a matching white line on the counters. They were deliberately placed in the pilots sight line so he knew how much he had left.

Just a word about the P Type RAF compass. The way it was designed to be used was not to move the clamped ring to find your heading. The idea was that you moved the ring to the heading you wanted and then turned the aircraft so that the north pointing part underneath aligned with the two parallel Lins above. As you observed it was an instrument that was more use in a ship or maybe a transport aircraft. Suffice to say that on the Tiger Moth I used to fly on pleasure flights we kept the P Type as a piece of history and had an E2B panel mounted compass fitted as well. This idea of having a compass where north wasn't quite where you expected it to be appears to be British as it was perpetuated in the post war Smiths Flight System where north was indicated by a pointer that could be anywhere on the dial depending on how the pilot set the desired track.

the radiator under the Hurricane filled the cockpit with heat because the Hurricane had no floor and the heat wafted up from below. It has been mentioned in numerous memoirs that it was stifingly hot in Summer. It also had a fatal flaw in that the wingroot fuel tank would blast into the cockpit if set alight in combat because there was nothing between the fuel tank and the pilot's feet. Incidentally, none of the prewar fighters had any credible jettison system for their canopies until combat experience in Spain compelled the Germans and others to fit canopy jettison systems. the 109 had a spring fitted to it's canopy and the entire rear section would detach to allow the pilot to get out. the Spitfire and Hurricane had a jettison system fitted later that allowed the canopy to be unpinned with the tug of a red ball and slide back fully.

But just by happenstance I watched a video about the Michelin star restaurant ratings by Max Miller on his Tasting History channel. I'm not trying to sway people from your channel but this is about history and as a WWII armchair historian, that story delves into something I never knew. I hope you, and others, watch it because it captures a glimpse into that horrible conflict in a way never expected.

The story of the Wilde Sau always amazes me how they flew unmodified 109s and 190s at night and tried to shoot down allied aircraft. They were suboptimal for flying in clouds, let alone in blackout conditions over Germany.

‘Eagles Wings’ is the autobiography of Hajo Hermann, the originator of Wilde Sau. An excellent read covering his whole career and he describes night missions against British bombers. If I remember correctly he preferred ex bomber pilots like himself to fly the missions because of their experience in instrument flying at night.

Great series. This is an interesting topic that would never have been covered by legacy media. THANK YOU GREG!

Quite surprised these planes didn't have heaters. Maybe my memory is playing tricks on me, but pretty sure Lindbergh in The Spirit of St Louis references turning on the cockpit heater in his DH 4 mail plane--a WWI open cockpit single engine bomber.

The Soviets used the handbrake-and-push system UNTIL THE END OF THE COLD WAR... the Yak-52 that David Gilmour (yes, THAT Pink Floyd) had such a system; Magnar recently posted a video about flying the bird.

Every video from Greg is a gem. As a passionate model builder and armchair historian I thank you sir for your dedication, hard work and commitment to producing these wonderful and well informed videos.

Nicely done, Greg - as usual. Really old people like me can remember when automobile controls and settings could often be done by feel, as well. My 2023 vehicle has lots more stuff to control, but it's all electronic displays that have to be touched in a certain way or in the right spot, and I have to look at the display (thus taking my eye off the road and traffic in the vicinity) to make sure I'm adjusting it to the proper setting. It's a (very) slow version of the fighter pilot's dilemma in a poorly-designed cockpit. P.S. I'm not able to access the patreon stuff. I get a page with an image of a WW I British fighter at the top, and a bunch of grayed-out boxes with no images or text, so I don't know what I'm looking at. Maybe it's the age and OS of my computer, but it's unique to your site. Help?

I think standardized instruments are the way to go, sure, but it is not that important as professional car and airplane testers tend to think, as a normal WW II pilot does not change airplane types very often. Only the good ones have the chance and they will hack it anyway. The bad ones are dead in a short timespan. Btw one of the best explanations of poor cockpit design is in astronaut Michael Collin’s wonderful autobiography „carrying the fire“ when he describes his test pilot experience. Very enjoyable to read!

You avoided perhaps the most important HF issue - visibility - something that was a priority to fighter pilots. The FW 190 vis was less than ideal looking over the control panel, although vis behind was good. The Me109 vis was of course horrible, also the early P-51's with bird cage canopy. Late model Spit IXs, XVIs had a bubble canopy, increasing vis considerably over earliest ones.

@@GregsAirplanesandAutomobiles who knew. I suggest that a video like this provide upfront an overview (good instructional design) of prioritized ergonomic and HF issues. The learner may therefore see the bigger and more accurate picture. Then identifiy the limited issues you'd like to cover in this video and label it accordingly. I hope that is helpful. I agree with the castoring tailwheel issue and pneumatic brakes (often mushy). When scrambling large #s of WWII fighters with limited fwd vis, proper ground handling was often lacking and accidents did occur, but the brakes/tailwheel problem was more of a systems design issue than ergonomic one. Cheers.

Great video

Outstanding as always Greg!! I knew you'd pivot to the 190 since the discussion was on human factors and I remember distinctly from your earlier 190 videos the exception cockpit design. That had quite and impact on me since it's typically not a point of discusssion. Comment - I'm wondering if perhaps it was easier to design a good cockpit for the FW190 since it was primarily electrically operated. It'd be far easier to place electrical switches where desired for reduced pilot workload as opposed to the mechanical contrivances like chains and pulleys on much of the P47. Would you agree?

Love the insight of the FW190 cockpit❤

Another great video Greg! I remember reading about the Hurricanes bobbing up and down after taking off because the pilots were busy pumping the handle to raise the undercarriage. Spitfire pilots were constantly having to change hands on the control column to perform similar tasks during take off. I also remember reading that German pilots after looking at captured examples, realised why they were able to jump British pilots, because they were so involved in engine and propeller management as well as maintaining flight position within their section and squadron. This last part changed with the adoption of the finger four formation learnt from the Germans. Mark from Melbourne Australia 🇦🇺

The 109 pilots had hellish manual variable pitch propellers far, far worse to cope with in combat. Every climb or descent or speed change cut or over-reved the engine losing power or threatening engine failure. Even worse their prop’s actuation was awful electric not hydraulic. Master race types would tend to boast superiority a bit too much.

@@givenfirstnamefamilyfirstn3935 That part I was not aware of. I do however remember reading a seasoned pilot's report stating that they would change the propeller pitch to fine (I think) in combat in order to raise the rate of fire from the machine guns. This was due to some of the machine guns firing through the propeller arc and having interrupter gear similar to WWI aircraft. Just how this altering of the prop pitch during combat affected engine performance and service life I can't say?

No floor in the Hurricane also meant punctured wing tanks with burning gasoline sloshing around inside the wing, vented out to the cockpit. Many pilots suffered greatly because of this. Sad.

I had read about RAF pilots suffering severe burns, but I had never heard of what you describe until I read James Holland’s “The Battle of Britain.” Pulling the canopy back to bail out would suck the flames into the cockpit. Not only could the pilots be injured, but their parachutes damaged.

Excellent - that's my entertainment sorted for tonight. I've been looking forward to this video since it was announced. It ties in with your work brilliant work on the Fw-190. i built a model years ago, which was rather disappoining, as the shape once finished was nothing special. All the few records I could find at the time said it was a great plane, but the specs on Top Trumps were pretty average, too. So, I never understood why anyone would consider it to be a great plane. Your video really hammered home the importance, on a fighter, of the human factor, largely ignored in my opinion elsewhere, especially when kids at school are comparing things.

BAAAAAHAHAHAHAHAHAHAHA GREG!!! That butthurt report is sorely needed nowadays. I laughed really loud when I read through that. Thank you for putting that at the end of your video (the rest of which was fantastic, as well, thank you for that, too.)

TYPHOONS.

I’m surprised that the twin-step rudder pedals on the Spitfire weren’t discussed. Maybe I missed it. The upper step raising the pilots feet relative to his head thus helping mitigate the effects of high G forces.

Get one of the fitters to drill some holes in the exhaust manifold. After ten minutes you won't fell cold at all.

Thanks Greg

Very very nice video, keep up the good work especially British aircraft ☺️

Did I just fall in love with Kurt Tank?

It's easier to feel a part of your aircraft (as any pilot should) when your cockpit is designed with you in mind.

Had a couple of flights in an L-39. It had the same taxi controls he mentioned for the Spitfire (except hydraulic vs. pneumatic). It's sooo weird for someone used to nosewheel steering and toe brakes. Damned near ground looped the thing because a full boot of rudder did nothing while the wingtip was headed for a fence. When I remembered the handbrake thing, I panicked and grabbed a big ol' handful of brake. The PIC didn't let me taxi for a while after that....

Brilliant as usual. Are you going to do similar type analysis of B-24/17/29's? I know fighter pilots had a lot to contend with, but it seems like the pilot and copilot of a B-17 was a challenge as well. The B-29 was ( I would expect) an even greater challenge not only for the pilot/co pilot, but the flight engineer. Any thoughts? Sorry I know you are busy and may not be able to respond. Thanks

GREG, did you notice the two level Spitfire foot rests, high for pulling Gs? Have you looked at wartime canopies, the curved panels can have fairly poor vision quality. Re. the vertical compass outputs, the U.S. Navy used a lot of Kollsman direct reading (via linkage) vertical compasses with twin bar heading bugs. They appear on e-bay regularly and work independently, the direct reading Mk X is typical. Thanks for the great work.

One is painted red for gear and the other was either yellow or white. Gear was in the center of the console and the flap was about 8 inches right of it.

Thanks if anyone offers an opinion. Sorry about it being off topic. I’m just posting while listening to the video……and smiling. Thanks for existing Greg.

FWIU the vast majority of Mk V Spits were upgraded Mk IIs anyway

Greg, this is a great series on Human Factors. Do you have plans to continue this subject, perhaps from a maintainability perspective?

Having used one of those huge compasses in the rear seat of a Harvard they are excellent and very very accurate.

Great video here Greg. There are several prototype pusher prop fighters but no real production craft, the only one I can think of is the SAAB J21 from Sweden. Could have a pusher fighter been competitive or were drawbacks from the layout insurmountable during that era.

@drewski5730

@@ivanthemadvandal8435I’m not Greg but I’ll try and answer. There just aren’t big enough advantages to the pusher design IMHO. 1. Most of the fighters of the era were tail draggers, due to the poor conditions of the runways they were using at the time. A pusher has less inherent prop to ground clearance unless you make the landing gear especially long, which has its own set of design challenges in terms of stability, packaging, and durability. 2. With a single engine the pusher design becomes especially challenging as where do you put the tail? Do you use canards? Canards were poorly understood at this time. 3. The loss of climb performance. Propellors mounted forward of the wings produce lift as a byproduct of torque; or for the layman, the prop wash over the wings produces a substantial amount of lift as a function of throttle. More throttle, more lift. I cannot understate how dramatic this effect can be, you can witness it firsthand at air shows where performers will hang a propellor driven airplane at near zero airspeed, well below the stall speed of the wing and remain airborne. This also effects take off performance to a degree. 4. In addition to providing more lift, the prop wash also makes the elevator and rudder on conventional tail aircraft more effective at slower speed ->again this is important when you’re talking about low time pilots as it makes the airplane easier to fly on and off the bad airstrips (or aircraft carriers), they were using. 5. Lastly it’s just a simpler airplane to design. Simple good. Edit: Pushers start to become much more worth it when in twin engine configuration. A push pull design for example benefits from 1 frontal disc in terms of drag, compared to a conventional twin that has 3. In essence for the same drag (frontal area), as a single engine airplane, you get the benefits of a second engine.

Hope there will be a 109 vid really love this seriers!

What an easy walk through the 'people' part of any machine as opposed to common sense...you'd think. It is fun 'riding between the wheels' so to speak and it had to be real blast having the feeling of flyin' a Spit between those wings.
