Good but could you use KMH along with MPH?

[Surakon 9]

As an American and retired machinist, I HATE METRIC

 

MPH to KMH = MPH multiplied by 1.609344

KMH to MPH = KMH multiplied by 0.621371

 

Max sea level speed  : 595 mph = 957.55968 KMH
Max speed at 10 000 feet: 586 mph = 943.07558 KMH
Max speed at 20 000 feet : 572 mph = 920.54476 KMH

hope this helps

imperial system FTW!

lol ok use the more stupidly complex system. get with the goddamn times

hey! the size of that kings feet has been used to measure stuff for generations!

 

have some respect ya damn kids. and get off my lawn!

When you grow up with imperial, it is not "stupidly more complex".

[vmaxWT 2,674]

Maybe not stupid, but more complex for sure (and i think that is stupid the use of more complex units)

 

[Foxztrot 220]

An argument over measurement systems rather than the stats of the Panther. Stay classy, WT.

o ya? well i bet you cant use your forearm to estimate the length of a foot, or use the knuckle on your index finger to estimate an inch.

 

hows that for easy, your a walking ruler!

ah lighten up don't you get tired of arguing about planes every once in a while :Ps

[Certified2Fly 6]

What would be awesome is if everyone would have to use knots for speed, nautical miles for distance, and feet for altitude. That is what aviation around the world uses nowadays. But then that wouldn't be historically accurate.

Just use whatever you want! :)

By the way cool stat sheets for the Panther. Would be nice if the speeds would be noted in either Indicated or True, even though its usually assumed they are indicated.

Ah aviation, such a complex industry sometimes.

Our current numerical system was invented to enable us to easily count from 1-10, not 1-8 or 1-12.

 

If you manage to invent a new numerical system, please let us know ;)s

Yes because there are 10 kind of people, if you know what i mean...

[Old_Crow51 336]

Where do the figures for having a faster speed at S.L. come from. Also is this an interpolation between numbers or just some tweaks for initial balance?

[Biplane_Master 38]

Such a high wingloading, and fuel tanks in the wings

 

it turns and rolls like a complete UFO in game, not to mention the climb, when will it be fixed?

Specification: Source: F9F-5 Data Sheet.

How is this a source? It was made by Danneskjold a Gaijin Research Pilot... not saying its false just a bit deceiving.

anyways... lets just check these to be safe

00,000 - 525 knots - 604 MPH  correct 604mph
05,000 - 521 knots - 599.5 MPH correct
10,000 - 518 knots - 596 MPH debatable but not gonna give much of a crap over 2 knots...
15,000 - 511 knots - 588 MPH again debatable but to little to be substantial
20,000 - 503 knots - 579 MPH seems right
25,000 - 495 knots - 569 MPH correct

ok good level speeds look fine now for climb

00,000 - 6000 - 0  correct
05,000 - 5500 - 0:52 correct
10,000 - 4800 - 1:50 looks more like 4850-4890 in my opinion
15,000 - 4250 - 2:56 looks right
20,000 - 3600 - 4:13 3400 not 3600
25,000 - 3050 - 5:43 not sure if 3050 but within margin of error, so correct
30,000 - 2450 - 7:32 correct
35,000 - 1850 - 9:52 correct 
40,000 - 1000 - 13:22 correct

Empty Weight: 10,147 Pounds
Weight Oil: 3 Gallons, 22.25 pounds.
Weight Fuel Fuselage: 763 Gallons, 4,578 pounds. what? total fuel (with wingtips) only weighed 3,611lb. EDIT: actually was just you referencing the wrong listed weights. 
Weight Fuel Wingtips: 2X 120 Gallons, 1,440 pounds (removable, but not droppable) correct afaik
Take Off Weight, full internal fuel and ammo: 17,766 pounds. um... not sure about this one... there was a config that gave this weight but then this plane would not perform like you said it does. The correct weight for the performance stats given is in fact 15,539lb.

 

stall speed is now a interesting subject... since the weights given are (by accident i believe) nearly 2,000lb off these are obviously going to be wrong. However the source listed does not give stall speeds for such weights. Looking into further documentation to find them...

Stall Speeds, No stall fences installed:
Full Fuel, Power Off: 112 Knots IAS. 129 MPH unkown
With Flaps and Gear Down, Power Off, 11,477 pounds: 94.3 Knots IAS. 109 MPH unkown
With Flaps and Gear Down, Power On, 11,477 pounds: 91.3 Knots IAS.  105 MPH. unkown.

I also found this well looking for supplement CO 01-85FGF-1A (Airplane Performance) to the F9F flight manual

If this is the actual climbrate then why does it climb like a complete UFO ingame? it climbs with the mig-15 bis and outclimbs sabre Fs, something's wrong

 

it out turns planes that have about half its wingloading and rolls extremely fast despite having fuel tanks in the wings

 

sounds like a broken FM to me

that must be because of the sabre's long period of acceleration to climb speed due to its lowe thrust/weight ratio

 

the mig 15 bis however, should accelerate faster AND climb much better, but ingame I outclimb the panthers only marginally, sometimes they outclimb me, and I always clim at the mig's best climbspeed of 710TAS

[Flying_pig 4,228]

well do you have a source for mig-15 climb? I think nabutso might have something on it... brb

EDIT: yah find time to climb but thats only half the picture...

anyways time to 16k is 1:57 (which does not reflect at all time to 20k)

time to 32k is 4 minutes 54 seconds which idk... I knew the mig could climb faster at high alt then a sabre but literally double the climb of a sabre is pushing plausibility a bit if you ask me...

anyways

You can see the actual sources used right at the top of the document. Dan just compiled it.
