I am bouncing on my parachute in anticipation of the Bombs, Fuel and an AI that will land someday.

This worked so well, I had to share. In My case no disassembly was required.

Since the ATC calls out the QFE in Inches HG and our Altimeter's adjustment window in the lower section of the Altimeter is in millibars, I found that consulting a chart was quicker although perhaps less accurate than an online calculator or using the constant to do the math every time. I am not referring to setting it to zero at the beginning of the flight which can be done either way but when coming in to land. The barometric pressure can and does often change from airport to airport as we know. It is standard to reset one's altimeter to the local conditions, elevations and pressure and very nice when it reads zero right at touchdown especially in bad weather. It is standard aviation procedure really. I couldn't find a suitable chart so I made one and sized it for a perfect fit in our kneeboard. I just fired it up and had to share since you folks help me so much with your posts behind the scenes. The attached pic can be retrieved in-Sim if saved in your Saved Games\dcs(whichever version)\Kneeboard\SpitfireLFMkIX Pretty handy

The point is the slot. The Boost will vary with altitude. It is simply an indicator I believe. All it is, is a curve in the slot. The throttle and every function would work exactly the same without the slot. It is there for Pilot feel. Since there is more travel after the end of the curve, I would say it is variable. The butterfly in the carb simply opens wider. More air, more fuel, more load on the moving parts, more heat. Add low airspeed, rad flap closed, high rpm and quickly *BOOM* You're a glider. Depending on altitude one can easily go from 12 psi to 18 psi all being in the WEP section of the slot and the Pilot would be expected to log that time in WEP. I like your idea of making it a physical thing one can feel. That rpm and boost will change drastically depending on altitude. Certainly, I found at the altitude the supercharger kicks into second gear or just before, 7psi boost is maximum before you're fully in the forward WEP area of the slot. 16,545 ft. in my latest mission. It will still climb up through the altitude where second gear kicks in and at that precise altitude in Full Speed Supercharger it can give you near 12 psi boost without WEP. That boost drops drastically as one climbs from there. At a low altitude one can go far beyond 9 psi boost without having to move the throttle that far. Try going up and down from 15,000 to 20,000 and watch your boost, oil and coolant Temperature, Oil pressure and RPM gauges while paying close attention to the slot. Try to stay out of the slot. *WEP* War EMERGENCY Power. There is no reason to work the engine that hard unless you're in a dogfight or dire straights. Staying out of the slot is not the only consideration for maximum engine survival. I spend most of my time at 9 psi with 2840 RPM while climbing to the altitude where it would force me to go into WEP which I won't do and so boost pressure will drop off more and more until the supercharger switches gears where one has to throttle back to get back down to around 9. Fly over some mountains. My knee board reference someone else made (Thank you Sir): pic attached.

Indeed the P-51 has been stated to have had the wire. The Spitfire has the curve in the channel and the Pilot was to report hours of use in WEP. I.E. Past the curve. Some models of Mustang also had water injection which was metered according to Manifold pressure (boost). It was turned on and off with a switch and had a light to indicate it was on. Water injection, I would consider part of the WEP as well if equipped. Water injection used to be big back when I was drag racing. It was said to cool the intake charge making it denser allowing more air accompanied by more fuel when on to give a bigger boom inside the cylinders. I am not sure it would add oxygen to the mix like Nitrous Oxide does. Alcohol would keep it from freezing and I would think help keep detonation down by raising the octane rating a bit and slowing the burn. Detonation, pinging, knocking is actually the tops of the piston flexing in response to too violent of an explosion in the cylinders instead of a nice burn. They cannot stand this for long. It will also pound crankshaft main and connecting rod bearings big time. Any time spent in WEP is begging for that kind of trouble with the increased compression pressures. In the old days of drag racing some folks had a high gear switch which retarded the timing in high gear which would help a bit. Today's engines adjust themselves to avert disaster pretty quick. It is so hard to find information about the actual workings of the WWII aircraft. cool link with a bit of info. https://en.wikipedia.org/wiki/War_emergency_power#WEP_in_World_War_II_aircraft The accuracy of any information I find on the internet of course could be false as we know.

It was considered however the WEP in the Spitfire covers a range of sweep and is not simply off and on. At a given altitude one can have a range from 12 to perhaps 18 psi boost or higher while in WEP. Note the length of the slot in the throttle channel after the curve. I haven't run across anything as of yet indicating that WEP in the Spitfire referred to water injection or anything that could be turned on or off by the switch at the ends of the throttle travel. It seems that it just referred to throttle position anytime it was moved past AND beyond a certain point which no doubt had some other things happen further down in the engine. I use the switches at the idle end of the throttle and the prop pitch rpm lever to operate my mag 1 and mag 2 on the Spitfire.

Since we as sim Pilots cannot actually feel the detent, I made it an idiot light. Here is my take on WEP in the Spit and my workaround. It seems to be modeled pretty accurately and I was wrong in saying the stock curve was off. I had changed the curve before I changed it again for this. 5 minutes: https://youtu.be/4uJ6eRH_T80

I got looking into WEP for the Spitfire. Apparently there is a curve in the throttle lever channel to give the Pilot an indication when the aircraft is in WEP. I stood up with my TrackIR on and zoomed into the channel in DCS. Sure enough the fine Devs haver modelled it faithfully. Very nice!

@Wolf8312 Thanks for the idea. https://youtu.be/AMFYbpEGfUw

It is possible with your throttle if you use the Target software. I'll make a video right directly. Even if you don't used Target, it doesn't hurt to try one thing. One would disable just that axis in DCS as well remember if you're going to use Target to assign the axis to a key. I will put it on the incr/decr friction lever. I will add a post very soon. (an hour or less)

Thanks @Yo-Yo. That explains things nicely.

Although some software such as Target for Thrustmaster products can assign a key press or combination to a function which includes using an axis to operate a switch. The mixture lever in DCS is kind of Full rich or kind of idle cutoff off at present. For now I assigned that to momentary switches. DCS does not have an axis bind for mixture at present. I remain hopeful that an Auto Lean position will appear someday as well as the ability to start it in the full rich position instead of it always flooding the engine. In my opinion over-priming should flood it more often than starting in full rich. RL flight vids would have me believe it is started full rich in reality. I believe although I am not sure that most cruise situations would normally be in auto lean. It is hard to say with all the conflicting internet based so called facts.

Yesterday as I was descending from 20,000 ft. gently, I turned the Supercharger to M.S just to save wear and tear, heat and perhaps some fuel. Without being part of the flight model, I doubt it makes a difference. The auto goes to high in that mission at 16,500 feet. One has to be aware of the fact that it will kick in at some point and if your throttle is pinned wide open which will only give around 8 boost psi as itr nears the auto-kick-in-altitude. before the supercharger switches to high gear. It can send it through the roof when it kicks in and damage the engine. This really becomes important when you are in and out of the altitude range where this happens. It will switch back and forth often. From 10,000 ft and up, constant monitoring and adjustment of boost is critical. One thing I do is as I climb and adjust boost as I go, when I get to the point that further forward motion of the throttle is ineffective, I move my throttle back to the point where it has an effect. I.E. If max boost at that altitude is 8.1, I'll just nudge it back to 8 rather than keep pushing it forward to full. That way when second gear kicks in, it is a bit less brutal going to maybe 12psi boost instead of off the charts. In a dog fight between 15,000 and 20,000 feet, the boost can turn on you if you don't keep an eye on it. Now if I could only find a way to change the default F1 view (With a track ir) so I could move back enough to see the boost, temp and pressure gauges. (I move it by using zoom at present which is not optimal. One could always switch to low gear 500 feet or so below the tipping point where the boost goes to high and climb through 16,500 or 17,000 (whatever the tipping point is for the weather which can change the altitude the auto switches it at). Then one could throttle back a bit, put it back into auto and get your boost back without rattling the engine parts. The bottom line is my supercharger control is on a switch and I use it a fair bit even if the results only exist in my imagination at present. I Love the Spitfire for all the manual controls. >>>>I can't wait to see the Mixture lever working as it should too. <<<<hint hint I enjoy setting up the enemy on the other side of mountains. Bring on that fuel tank. My wingman does not manage his fuel well nor do the other 2 AI aircraft in my flight.

Indeed. It is great news.

Although i have seen fps well past 100 on my machine, I found that checking off Vsync in the settings which limits it to 60 gives more consistency to my flight behaviour especially on landings. Picking Default in the Nvidia control panel and checking off Vsync in game really seems to have helped me a lot. It no longer glitches out if it gets busy like when my wingman flys past me just as I am coming in for a landing. Now I see 60 fps rock steady across the board and I have not missed one single landing in a week which was not the norm before. That is a lot of landings for me. We are talking a Spitfire. Good to go.

The Spitfire mirror in the rain behavior seems to also depend on altitude. Or is it the rain turns to snow or the temperature? It comes back on between 9 and 10,000 feet If I recall. Ok back in the. Loving 2.5.2 and the Spit btw.

I have been really enjoying the rain and snow effects in 2.5.2 as of June 1 but I missed my mirror and so made a temporary workaround. I simply chained a Mirror Glance command to my Cockpit open binding which I moved to my Mirror Glance Binding. Now when I hit Mirror glance the cockpit opens so I can see the Mirror. Since the "Mirror Glance" is a hold and the cockpit open and close are a pulse, One does not hardly notice the mirror glance when one only opens the cockpit. I did not have the cockpit close on a release since I wanted to use that same function as my cockpit open, cockpit close. Works well. I don't think this is cheating. To quote Clint: We adapted and overcame. ;) I can make hide nor hair of the code: MapKeyIOUMD(&Throttle, MSR, 0, 0, 0, PULSE+R_ALT+'e', 0, 0); MapKeyIOUMD(&Throttle, MSL, 0, 0, 0, CHAIN( PULSE+R_ALT+'v', D(), R_WIN+'n'), 0, 0); GUI pic attached.

Thanks @Mule and all! That changes everything.

Air Quake Spits on Spits in the caucus would be an interesting diversion that I could get somewhat addicted to gladly. If I had 2 cents to rub together it'd already be done. No complaints about mismatched aircraft could ensue. Air starts are something I would have to mull over though. Too much crashing to re-ammo up would be the result of that I would think. That behavior is rampant in the MP world in other game/sims. One needs to cherish and earn their ammo and take care of their aircraft. I am back to new to DCS multiplayer totally since it's been a couple years and I barely got a taste of it before. There is not much out there that appeals to the Spitfire in open servers. So be it. I actually enjoyed having an F-15 on my wing for a few seconds the other day. I thought "A real human wow". 3 seconds out of 4 hours. Multiplayer? Excuse me? Ain't happening here in the daytime. I am home pretty much all day every day and man it's hard to find a logical game. I mean 4 spits and 83 Jets? LOL. Whatever. Enjoy! We'll get there. I do own a 109, 'stang and an F-15 as well but the Spitfire has me hooked bad now.

One could look into an auto wreckers for one with seat covers as I did. I shampooed it and it is the cat's a$$. This cost me $34. Absolute all day comfort and it is thick and cushy enough that one could push the stick another few inches into the "plushness". The extension is for the warbirds I am so fond of.

Spitfire sunshade is clear when raining. 2.52.

Sorry this is a duplicated post. Is this where this goes?

I just spent a couple hours on the latest release of the Beta. This is my first install of the BETA May 30TH. If I have rain on and close the canopy the mirror goes black. In clear weather it is fine. Edit: it messes up just with any clouds at all as well.

Holding the brakes on makes warmup at 1500 rpm (as per manual) possible. If one hits "increase brakes" 7 times it will hold the brake on. Holding the brakes on by holding w or a mapped to joystick "W" is not a good plan. It's never good to have a key held down virtually or otherwise. My brake latch is my pinky switch on my TM hotas. I would think this is easily done in Lua as well however I have no idea about Lua yet. Using the Thrustmaster Target software one could do something like this which is how I handle it today.
