There is a jpeg of a pilot card for the Seires II / Sabre IIB as of Feb '45 (though this should not be immediately seized upon as being only flown from Feb - this simply happens to be the date of this particular card). It refers to '5 min combat allowance' in terms of range reduction but would have to check my Pilots Notes for actual engine limits but it would be nice to see power over recommended time = sudden massive engine temp rise that can be controlled using radiator and rapid engine management rather than 5:01 = 'bang!' 2050hp for 1 hour 2400hp for 5 minutes

I agree that flaps need to be revisited, but they have some plan how they develope things. For me personaly its not that big issue, because i play sp only and im not gaming the game. I use flaps to take off and landing.

My bad, I failed to properly convey my meaning here. I meant not as good as is often thought, since the values for a spring-tab equipped Tempest are often thrown around on the internet. Also, it may be trivial, but I feel like saying it anyway just to avoid confusion, it's obvious that the roll rate didn't get better as speed went over 300mph. What it did was get worse, but at a slower rate than that of a standard, fully-winged spit XVI or a 109.

Yes, I was being vague about the ‘300 mph’ point, but 3 things: - Its rate of roll was good by contemporary standards across the speed range - At 300mph, sustained roll rate was 100 degrees per second which was better than its roll rate below 300 mph so rate did climb with speed - Roll rate appears to have peaked at around 300 mph, so not only did its roll rate improve at (rather than beyond) 300 mph, but its comparative roll rate also rose above this speed.

Are we to assume it's working as intended? You have a source on the L/D ratio with flaps deployed that I can test to? So far I've found references that one flap would deploy to 20° before the other moved, and that if you lost hydraulic pressure, they'd snap shut suddenly, but finding how the aircraft behaved with flaps down has been rather thin gruel.
ZachariasX Posted February 26, 2019 Posted February 26, 2019 13 minutes ago, Voyager said: flap would deploy to 20° before the other moved That would kill you. 14 minutes ago, Voyager said: if you lost hydraulic pressure Regarding hydraulic pressure check the dial, it should read 1000 psi, dropping to 100 to 200 while either gear or flaps are moving. If you have the flaps lever on "neutral", the flaps circuit is locked, meaning the valves on both sides of the flaps actuator are shut. You can drain all oil in the system, as long as that lever remains in "neutral", the flaps won't move. If the oil is gone and pressure to 0 psi on the dial, if flaps are deployed in flight in any way (position up or down of the lever) will make the flaps being immediately pushed up by the airstream as you open the sealed of oil tubes. In the Mustang, you have a lever for relieving pressure in that oil system. You pull that red handle (down between your legs to the right side of the control column) and oil pressure drops to 0, making flaps fall down all the way. It is how you do it to park your plane for an extended period of time. You'll need a running engine after shutting that valve again to buil up pressure to 1000 psi, then flaps can come back up.

It would kill you if you are in a near stall turn. In level flight with 140mph indicated it just requires a lot of control inputs and side slip correction. NACA Technical Note 2899, pg 60, shows both flaps dropping to ~5 degrees, then the left extending to ~20, then the right flap, then both out to about 40°. It also shows a plot of the pilot stick and rudder inputs at the time. The P-47N manual pg 80, states that flaps take offs are strictly an emergency procedure, as there's always a possibility of one of the flaps coming up and making the plane difficult to control. Things like that, that modern pilots would consider "will kill you" flaws are the sorts of things I'm finding as I'm digging deeper into the Thnderbolt's flight characteristics. I doubt all the pilots who called it "gentle" "easy to fly" "mild stall" were wrong, within their frame of reference, but I've come to seriously question what that frame of reference actually was. I doubt the Tempest or the Mustang are going to have fewer hidden surprises in store for us. Edited February 26, 2019 by Voyager

More than enough to snuff you out in the long run. Remember, flaps are something that come into play when there is little distance between you and your future point of impact. 5 minutes ago, Voyager said: The P-47N manual pg 80, states that flaps take offs are strictly an emergency procedure, as there's always a possibility of one of the flaps coming up and making the plane difficult to control. How much of a difference visually would you tolerate for a take off into English weather? Just in comparison to „at 140 mph, 15 degree difference is easily controlled“? The P-47 is a handful even when everything works out well. Real world, real airport traffic and real stress eat enough margin for making sudden asymmetric flap failure quiet an issue.

Yet another reason why flap usage for BFM was extremely rare for all a/c, not just the P-47: with the exception of the 190 electrical settings approach, the things were simply not designed for this kind of usage and too unwieldy for the fine-balanced, multi-tasking that such flap control required. Anyway, the Tempest has big ol' barn-door flaps so their use for esoteric maneuvering will be severely limited.

In cases where they are just intended for takeoff and landing, they are designed with different characteristics and tolerances. The P-51 flaps were just a happy accident.

Something tells me they weren't like that just cos. Sorry, are you suggesting that - in 1941 - the North American team decided that the P-51 flaps would be an integral part of combat maneuvering and therefore designed ultra-resilient flaps for this purpose to be used at 400mph? That would be a trip into post-facto fantasy land. 'Rated for', 'intended for', 'actually used for; and 'occasionally someone used it in this way' are extremes of a spectrum. You can drop your landing gear at quite high speeds if you wish - above recommended airspeed - but that does not mean that the system was designed with such operation as a core element. Most mechanical objects are rated to one standard or another, sometimes of a more or less usable nature. It turned out that the Spitfire wing had a critical Mach of somewhere near .92, I do not recall Mitchell intending that this be a core element of the Spitfire's BFM repertoire nor it making it into the pilot notes. People can keep on insisting that DF server flap use is somehow reflective of actual flying as long as they wish, but they will carry on being mostly wrong about it. Pilots did dial in some flap on occasions, but in general the control surface was not intended that way nor did they function in a manner consistent with rapid and precise deployment to suit changing aerofoil conditions. Some a/c had flap settings that could be used during flight, but they were a minority and it does not mean that such flaps were frequently used or were particularly effective. I am not sure - for example - what you would usefully do with 10 degree flap at 400mph: at that speed the centre of lift is probably quite far aft (more so on a laminar flow wing) so any flap use would probably cause a nose-down change and in any case you have enough speed to generate a lot of g if needed. If you can provide a good argument as to why it was felt that 10 degree of flap was intended for use at that speed - as opposed to being merely the structure limits of the airframe - then I will concede that maybe it was intended all along. Back to the Tempest which had boring flaps used for landing in order to allow slow Spitfires to catch up. 2
Gambit21 Posted February 27, 2019 Posted February 27, 2019 I asked specifically about use of flaps in combat while interviewing 352nd Mustang pilots (as well as Bud Anderson) and all of them indicated that they didn’t do it, nor did they know anyone who did.

Absolutely. I’ve dropped flaps and gear to win stall fights against better maneuvering aircraft that should have gotten me killed. I’ve also mis-judged and ended up auguring. No re-boots in real life.

There were only few pilots who had the balls, dedication or wonder of what would happen if you did this or that and experiment. Encouragement of those who wouldn't try by themselves was down to the squad-leaders. Thinking outside the box is usually not encouraged by a system that drills compliance to procedures from day one. There is only one "right way" to fly - be it by the recommended procedures set in the Flight Manual or be it procedures thought up in squadrons. Tactics were mostly down to the squadrons and thus the use or lack thereof of flaps was most certainly discussed (or not) on a squadron level. That is apart from a few handful of pilots who tried anyway. Ze Germans (TM) had those few pilots, too (see Marseille for example), but in general the use of tactics was down to how the squadron did things. A change in leadership often brought changes in tactics and procedures.
Voyager Posted March 3, 2019 Posted March 3, 2019 Just remember, thinking outside the box, and being wrong got you killed too. I recall the story of one pilot who figured that the compressability problem they were running into was a version of control reversal, so he took his plane up to altitude and entered into a tremendous dive to test it. The other pilots in the squadron were impressed that the fuselage was still recognizable after the impact.
Bremspropeller Posted March 3, 2019 Posted March 3, 2019 That's precisely why procedures are hammered into pilots during training and why they're tested for in checkrides time and time again. Standardisation is king. This has lead to safety-increases of one or two orders of magnitude in terms of accident-rates over the past couple of decades.
