F15 top speed

[tyugh42]

I am thinking about purchasing the FC3. Do anybody know the top speed of F 15 in FC3? I have the original Lock On Gold edition FC1 and the top speed of F15 is approx. 750 mile per hour or Mach 1.3 regardless of altitude. The most I could go in F 15 is approx. 920 mile per hour or Mach 1.4 during a dive from high altitude.

Just wondering out of curiosity, how does this affect your decision to purchase/not purchase FC3?

 

At any rate, many MANY things have changed since FC1. In FC2 I managed to get an F-15 (fitted with all pylons but no weapons) to Mach 2.484 at 35,500' which corresponds to about 1642 mph at that altitude. I would imagine FC3 is similar. Comparing to the official manual for the F-15A/C, this is pretty darn close to the real thing. Some people have gotten it slightly faster.

The F-15C is getting an AFM, so it should be pretty darn close to the real thing real soon...

If my understanding is right the outside view bottom chart shows TAS. I've experienced 1300 knots TAS at high altitude dives. Cockpit instruments and HUD shows IAS, as far as I know. But you need to drop attachments otherwise you'll get stuck at much lower speed.

 

Besides, these top speeds are irrelevant in combat. The only time you'll be faster than M1 is the initial BVR volley.

In FC1 the F-15 could do mach 2.5, you're obviously either not doing it right or not looking at the correct gauges.

Mach 2+ easily done with a clean AC in level flight with current version.

AC was still accelerating when SS was taken.

I just want the game to be more realistic, that's all. It is like playing a car racing game where to top speed of a Corvette is only 60mph. But I think I will buy it. I still couldn't figure out why I could not get up to that speed.

I usually top off at 700 knots with full load...

FC3 is just a game, not a simulator, they try to leave the F-15, equivalent to the su-27

to try to cheer both sides

on module FC3 R-27ER missiles are faster than the AIM-120 missiles, and in fact this is not real.

indeed the missile R-27ER speed mach 3 and AIM-120 missiles speed Mach 4

This is Indicated Air Speed (IAS) not your True Air Speed (TAS), you need to look down at your IAS indicator below the radar and check the inner dial for 'mach' reading. Your IAS displayed on the HUD will not change at different altitudes but your TAS increases with altitude.

 

700knots IAS(HUD) will be 700knots TAS at 10 feet altitude, while at 35000 feet 700knots IAS(HUD) will be more like 1250knots TAS (nearly mach 2.2).

It's a simulator, the aircraft are modelled as close as possible to their real life performances. This is why F-15 and MiG-29 are faster than Su-27.

R-27ER is mach 4+.

HUD also shows Mach # accurate to the third decimal place. There is also a machmeter on your airspeed gauge. TAS and GS can be read from VSD.

in modeling issue are great

but in a matter of actual data is poor

'm also a fan of the work done by dcs but FC3 is just a game

All of DCS is a game, by definition it is an enjoyable past time that tries to simulate real life.

 

FC3 is firstly a combat simulator, it simulates the combat operation very well, it doesn't have a clickable pit and the avionics are not fully adjustable by the pilot but those systems are still simulated to behave as they would in the real world. The SFM is not as advanced as AFM but it still does a good job of simulating each aircrafts flight envelope. The weapons perform as they do in DCS and the weather is simulated to affect the aircraft.

 

There are many things DCS doesn't simulate does this suddenly make it no longer a sim?

I just purchased the FC3. The top speed is actually worse than FC1. It will take a long time to reach Mach 1.1 @around 30,000ft with 3 fuel tanks. I Both engine rmp at 110, max throttle. Am I missing something here? It is kind of frustrating.

[GGTharos]

Yeah, you're missing the fact that you're hauling a bunch of draggy fuel tanks. Where did you get the idea that you'd be able to go fast with them?

 

And why are you hauling 3 tanks if you're planning on a sprint? Fuel tanks are used to increase range or endurance, not sprinting duration.

I actually tried to fly without any external tanks. The top speed is around Mach 2.3. I didn't know it would make such a big difference. Thanks for your help.

I saw on the specs that the top speed is Mach 2.5 but I guess they didn't specify that it is not fully loaded. I guess in real combat, the plane can go travel half of the top speed due to the external fuel tanks, bombs and missiles.

[mvsgas]

Remember that aircraft top speed is just that, the maximum publicized speed the aircraft can achieve. Little to do with operational speeds, meaning the speed they normally fly at.

 

Same goes for all aircraft public specs. An aircraft maybe be claimed to have range "x", or speed "y", or maximum g of "z" does not mean the aircraft will be able to do that in all situations.

 

For example, F-16 can sustain 9g, but not with some load outs.

A-10 could carry a 16k lbs of ordnance in testing, IIRC, but it would be so slow and not maneuverable operationally, so it would be impractical and unsafe.

Wikipedia by no means is an accurate source of confidential technical data, however the AMRAAM is listed with a max speed of Mach 4, while the R-27ER is listed with a max speed of Mach 4.5. If ED used those data, then they did right, because this is what commonly is known about those missiles. The actual data may vary, but we'll never know...

[Robin_Hood]

The fact that modern fighters tend to have top speeds inferior (or at any rate, not greater) than those from the 60-70's should tell you that top speed doesn't really matter.

 

There was a time it was a concern (think MiG-25 and SR-71), but not so much now.

[tyugh42]

Thanks you guys for the advice.
