P-51D vs Fw190-A8

[CavemanJ]

I was a P-51D with the 4gun loadout vs a Fw190-A8 (not sure on loadout).  I had about 3/8 fuel in each wing, don't know about the Fw.  I was doin a little better than 400 mph, 1.5 behind the Fw, chasing the Fw east, and the range stayed 1.5 from passing V2 to north of A1 (yes I know that means 1k to 1.5k).  Tool8 (the Fw) went up and over and I went up with him, taking a shot at 300-400yds and smoking his oil, then following him back down and hit wep (which lasted about a minute cause I had been using it earlier).  Now we're going west, with him apparently running for A22 with me in hot pursuit.

Now.. which bird should win this race?  The Fw was steadily pulling away from me, like I had 2-3 cylinders misfiring.  Tool was surprised he pulled away from me to get away, and so it seemed everyone else was too.  Or did I have 2 or 3 cylinders misfiring?  I got walked by a Fw190-A5 earlier in the same flight.

Bug or was I wrong in thinking only the D9's faster than the pony on the deck?

I've never escaped from P51 in a 190A8 in that situation. Only way to survive is to shoot that P51 down and if you fail, you die.

[JaniKu]

Well...I was chasing that 190 also, but the p51 just couldnt cath it.

I just did a quick test of deck speed.

Took off from a1 headed se otd with 25% fuel and 2 x 20mm mg151 in an a8



while level I waited untill speed evened out nad ran until it wouldnt gain any more speed. 390mph

Same with the p51 25% fuel with the heavy 50 cal load (dunno what it is as I never fly that plane)

[BenDover]

thats strange, the true and indicated airspeed match....what alt did you take these readings at?

[DmdJW]

Batz, did you do both runs on the deck?

There's a difference between the indicated and true airspeeds on the 190. If you look at the P51 the indicated and true airspeeds are the same, what you'd expect if you were at sea level.

[BenDover]

Beat you to it:p

[Eagler]

i dunno nothin but I heard several indicating last night in beta that the speeds were still off on several planes

[Batz]

The a8 has a bug, even on auto level it will climb.

Started at sl and climbed to maybe 500 ft.


You cant trim it level and holding it level via the stick impacts its speed.


SL to 500ft for the a8.............

In an earlier announcement, hitech or pyro mentioned that indicated airspeeds would show errors based on sideslip angle and other aerodynamic factors.  In real life, planes have a certain amount of error in indicated vs. actual airspeed because of installation errors, pitot/static probe position, and other aero factors.  This is why many planes will have an indicated vs. calibrated airspeed chart in the pilot manual, and why modern aircraft will use an integrated air data or flight computer to display calibrated airspeed (CAS) instead of indicated airspeed (IAS).

From what I've read in news and announcements, I think that in AH "calibrated airspeed" (acutal airspeed) was being displayed, and in AH2 "indicated airspeed" (airspeed with errors due to installation error and aerodynamic factors) is being used.  I do not know if HTC is modelling CAS into aircraft that had airspeed calibration computers installed, and I don't know if there were even any of those computers in use during WWII.  I do know that there are mechanical/analog computers that can make these calcuations based on angle of attack, altitude, sideslip angle, temperature etc. using technology available as early as WWI, but I have no idea when they entered service.

Or it could be a bug.  All we can do is report what we see

[ChasR]

The chart in the AH1 manual has the true airspeed of the 190A-8 on the deck with wep @ 350mph, w/o wep @ 330mph.  The P51B is shown @ 360 with wep, 348 w/o.  The 51D model 370 with wep, 355 w/o.  The 190A-8 has obviously gained quite a bit more speed than the P51 in the AH2 model.

[CavemanJ]

Thanks Batz, I didn't check the speeds last night because I logged when I landed and wanted to get the details down before they got fuzzy.

Earlier in the same flight I was around A22 fighting GF, who said he was in a Fw190-A5.  At 12-14k I didn't have any trouble out distancing him after a spit and p40 got high enough to join the fight, though I can't say for sure he was seriously trying to catch me.  The spit stayed closer than the Fw did.  He caught up again while I was playing in the vertical with the spit, and following the self preservation sense I left the nose down and ran for A1, slowly overcoming his advantage from his dive and getting close enough to the base for him to pull up and over and go for another target.  I went over the top, took a shot at the spit, and turned to chase down the Fw.  Never got the icon below 2.5k range.  Alt of this chase was around 3k I guess, because we were flying along the hills and not right down on the deck.  This is where I burned most of my wep before I peeled off south of V23 and headed towards the center of the island, where I ran into Tool8 and his -A8 described in the first post.

Only 2 glaring things I noticed early this morning.  And if it's a feature of the model that brought this about so be it.. just gonna take alot to get used to having A5s and A8s out running my pony =)

Seems like all OTD speeds are different in this beta. Below is the speeds of La-7 and Fw190D-9 (25% fuel), Dora is now 423mph:eek: La is not the fastest unperked plane any more...

[icemaw]

I might be wrong but shouldent true indicated and groud speed be the same on the deck. Looks like that may be the problem with the FWs. Unless there was a wind layer involved. But wind would effect both planes as long as they where travaling in the same direction relitive to the wind.

[leitwolf]

The A-8 hits 390mph TAS on the deck easily now
I also noticed it does not have fuel in it's AUX tank anymore - does this mean it has MW50? 390mph seems to be on the "high" side for a 190A  I think. A LuftWhine has been recorded
