Learning the SU27

[jaznit]

Hi all

 

So I've spent alot of hours learning the F15c, and whilst I am in no way a master I think im ok. I understand the radar system and how to fight air to air... but I get smashed by SU27's ...

 

Whilst practice will improve my overall ability to dogfight, IO am keen to learn the SU27.

 

What have I noticed so far? I put it down to the below:

- Firstly, It's harder not having the dashboard in english! Taking me a while to learn what's what at a much slower rate.

- Secondly, compared to flying the F15c with 3 fuel tanks I notice the huge difference in fuel supply

- The radar system at BVR seems better? But comparing what i'm used to in measurements in the F15c I can't quite understand the ratios in the SU27. Such as the 160nm BVR in the F15c.. is that the same as the 200 or 500 in SU27? and so on

 

Early days still but a fun plane.

 

After your experiences, thoughts, etc

There are mods out there with english cockpits for virtually all planes. The radar on the F15 measures in NM and the radar in the Su-27 measures in KM but neither can pick up a lot of targets at their max range. Nothing fighter sized, anyway.

The quick way to convert km to nmi is just half it, eg. 20km = 10nmi.

This works with the caveat that there are actually about 1.8 km to the nautical mile, so you need to keep in mind that simply halving the range in km will underestimate the range in nm. To use your example, 20km is actually 11.1 nm.

160 nm is roughly equivalent to 300 km. Unless your purpose is to compare ranges for first launch capability, it'd be best to simply start thinking in kilometers and meters and don't try to figure out what it means in "Imperial". You'll drive yourself crazy and gain little, if any, benefit in the process.

 

Max detection range for a fighter sized aircraft will be around 100 km at best, if you are doing everything right. Once you have a target locked, you will get Rmax, RTR, and Rmin tick marks on the range scale (left side of the HUD). Just use those to determine when it's best to put a missile into the air.

 

And welcome to the "bright" side. :) Enjoy the aircraft.

Checkout Flankertraining, some good videos there.

For Su-27 pilots it is recommended to think in Russian.

It's actually 10.8nm but this is nit picking when converting for the sake of understanding engagement ranges in nm when you're used to kms. The idea is that someone who is used to 20km being the danger zone can easily convert this to 10nm being the danger zone. :)

eh, I think you mean nm here?

If you learn basic Russian lettering, you can actually understand most of the text from the HUD.

 

I am still struggling with funny looking letters in Cyrilic (Phi, Shya, Za, etc..).

 

I like the Su-27 because its an A/G plane and because of the ASC cobra. Problem is, the autopilot is so fluttery and causes some sorts of oscillations (I don't know what is the recommended IAS in Km/h to get consistent FC2 behaviour).

I'm guessing you're seeing weird oscillations when you try to use the autopilot at low speed and / or high altitude?

 

As it currently is the autopilot has to be engaged when your indicated air speed (not true air speed) is at or above 550 - 560 Km/h. Any slower than that and you'll see the oscillations and yaw gyrations. These will also happen if you successfully engage the autopilot but your IAS falls below ~550 Km/h.

 

This is a known bug. The real Su-27 has an auto-approach autopilot mode whereby it's capable of flying the aircraft to the point of touchdown on the runway, which obviously involves an IAS far below the 550 Km/h threshold value that exists in the game.

 

That being said, the only practical problem is that this means that you can't use the autopilot at anything over 10,000m altitude because at any higher altitude unless you're in afterburning thrust your IAS will always be below 550 Km/h.

I agree, but has this bug been ever acknowledged?

 

Thanks

Yes I think so. I think the ED chap working on flight models commented at some point that some minor tweaks remained with the Su-27 flight model, though I'd guess that it's close enough that any remaining issues are a fairly low priority.

 

I gather that it's 99% working as intended.

Well, no, its not even really close. 1.6 km = 1 mile

[Ironhand]

Nautical mile, not mile. 1 Km=0.5399555 Nmi :)

Great, now he can convert both. :thumbup: Besides, I think NMI was made up, I had no idea what that was. lol

[Ironhand]

...I think NMI was made up, I had no idea what that was.

I actually checked on what the accepted abbreviations were before posting my last. It can be NM, Nmi, and sometimes simply M. That last should really confuse things. :)
