Do any of the A/C speeds match the Charts?

[F4UDOA]

Heya,

Just for kicks after reading the P-47 and
P-38 threads I took a F4U-1D up to 20K to check top speed. As previous post were tested I dove down WEP to 20K and reached a speed of 450mph plus. Then watched it declerate down to just a hair over 400MPH with WEP. Top speed at this alt should be 425MPH according to chart. The I tried the method of setting auto climb to 400mph to check for accuracy. Went into steep dive, repeated test down to 380MPH all resulted in a rate of desent for the A/C. Does this mean that the top true airspeed of the F4U-1D is 380MPH? I am not sure what this method of testing proves? In anycase has anyone tested and A/C that matches the charts in AH?
Seems the higher you get the further from the charts you get. FYI, the climb did seem to match throughout the test.

BTW, could never understand why Jug pilots screaming about not being able to climb with WEP. If that were my bird that was porked I would be in 3Xrant mode all the time.
Jug pilots need to speak up a little.

Trim speed has to be in IAS, not TAS.  For 425 mph TAS at 20k, you should be reading 309 trim speed.

Yes i believe that the Autoclimb is in IAS not TAS.

I fly the P47 so I didn't test other airplanes. I just noticed 1 time that the f4U-D1 took more than 20 KTAS low when already flying at top level speed, I kicked the Wep on to evade a Spit.

Looks like HTC doesn't really care about our imput anyway DOA   They probably have something more important to do right now rather than to try to make their plane perf match with their own charts. Maybe one day they will foccus on Planes matching their charts data... maybe 1.06  

So far, even my P47 is proked, I can still have fun dogfighting in it. It's just harder to kill hehehe.

Ahh Wells,

You are the Jedi master. I didn't realize that.

However the TAS indicator was just a hair over 400MPH TAS. Will have to retest for a more accurate number.

BTW, I have some really exciting new documentation provided by my buddy
Frances Dean and his friends. This guy is a wealth of info. Will give you details offline.

F4UDOA, did you ever ask Dean if he had any information on late/post war testing on Ki-84's or N1K2's by either the AirForce or the Navy?

I know it was conducted, but can't find any original documentation.

In particular, I'm looking for the Testing where the Ki-84 reached 427mph.

I hope you are kidding.  If you are not kidding then you haven't been reading the boards and the readme files very much.

Funked,

I didn't say that. That was Frenchy.

If you want HTC to listen you just have to know how to phrase the question.

If only I knew how to ask for a F2G??

Verm, you should be getting an Email from me on that subject.

[juzz]

F4UDOA; Funked didn't say that you said that.  

[SFRT - Frenchy]

hehehe Funked, this sentence is supposed to be followed by the rest of my message  

You right, it says something that I didn't mean to express. I noticed something starnge with the P47 Wep, I post (with ur help) a message to Pyro. Pyro answers me that he did tests and it's ok and propose that maybe my tests are out because of wrong plane config or gauges. I redo the tests following his advises with an empty P47, I still find the same problem asking if it's still "normal", and Pyro doesn't answer anymore.

I just wanted to say that each of us in the AH comunauty may have a specific problem who is big for us (like my P47 speed cause I LOVE the P47, but a Spit pilot would care the least). HTC and Pyro see the "big picture", they can't answer or treat each individual concern because what is big for us, may be a drop of water in the ocean for them.

Like I already said, comunication and involvment of HTC staff toward his comunauty toward BBS and patches is not 100% but it's FAR SUPPERIOR to any game I played online for 3 years, and i was always impressed by it.

Makes more sense Funked?  

[funked]

Makes sense.

Tested the Ju88 yesterday for speed vs some #'s i have here.
Book:  Ju88-A4 293 at 17,390 ft
Aces:  293 at 17,400 ft (approx taken from the guage)

+) ok so no chart to compare, but the speed is exact match.  Though i did find the ceiling of both the ju and lanc higher than the book (Combat Aircraft of the World)

[Pyro]

Checked it out and the F4U is different from what's on our page.  I'll have to check out the rest of the beta planes as well since the same thing's going on with the N1K2.  

Frenchy- it's not that we don't care, but there are limits to how much we can do at one time.  If my main priority shifted everytime I looked at the BBS, I would never get anything done.  I have to allocate time to go do various things and it's rarely fast enough for anybody, including myself, and I'll never be able to get to everything at once.  I have to watch my limitations too.  It's not hard to get burnt out from time to time if you do this long enough.

Pyro,

Really wasn't picking the FM. Just pointing out that all of the A/C are a little of of their charted speed and climb. Which really isn't that much of a problem as long as it exist across the board. Especially since most production A/C varied slightly from stated performance.
