Tips for keeping the energy for dogfighting

[WildeSau44]

Hey guys,

I see some videos on ytube of ppl dogfighting almost without losing energy. Well, not me! 
I am not sure what I am doing wrong. I even cheated using unlimited fuel and abusing the afterburner.

My dogfights always start with energy but as I start turning and chasing, I lose energy so fast that I need to dive. Then I get some distance turn to face the enemy and the energy is gone again. I keep fighting stalls.

Any tips and advices would be much appreciated.

Thanks!

There's no magic to it. When you go down you get energy back, when you go up you lose it. AB can accelerate you but only if you don't kill the thrust with the drag. That means you have to control how many Gs you pull on the stick. If you're fast you can afford to pull more. If you're slow you have to be gentle with it and allow it to regain the energy - yes, you'll lose some angles, that's part of the game. You can also mix it - pull more while nose down and pull less when going up. Practice, practice, practice!

Specifically for the Tomcat, as a rule of thumb, try to not exceed 15 units of AOA when turning, or you'll rapidly lose energy. Pay attention to the audio-visual feedback HB baked into the module, this will give you hints as well regarding your energy state. Don't fly lead/ pure pursuit until you are in a good position to take a shot. 

Other than that, practice. Learn how to modulate stick input. Your best rate turn in the Tomcat is 307Kts at 6.5g. I'd set up a simple exercise where you try to hit those numbers. You'll develop a feel for that eventually (probably easier IRL, as you don't feel acceleration/ deceleration and g-forces in DCS).

FFB stick helps a lot!!

Where do you get that precise number from?

"Paco" Chierici, via Reflected's Speed & Angels campaign. It's in the campaign doc for mission 6.

Err... that's very, very wrong. You're probably thinking about airspeed. Going up is the best way to save energy while still being able to make a tight turn. In fact, going in fast and pulling up lets you bank that extra energy and maintain your best turning speed, while being able to pull a bit higher G than 6.5, since when you're coming down, you're gaining airspeed, so anything above about 310kts can be turned into Gs at your leisure. Very few things can defend against an F-14 that can use the vertical right.

Yeah, that's better wording.

[Dragon1-1]

It's not a matter of wording, but of factual correctness. Airspeed is not energy, that's the whole point of the E-M theory.

[AH_Solid_Snake]

Its mostly wording, no need to get focussed on nitpicking other answers while not contributing to the original question.

What @draconus was aiming at was kinetic energy, what @Dragon1-1 is talking about managing is potential energy.

Think about it a couple of ways, before the fight you have all the time in the world to set yourself up for a good engagement, build up a solid bank of both types of energy (get high, get fast). Then think of it as making trades, you don't want to tank all your potential energy on the first turn, if you just spiral downwards pulling all the Gs you will trade away everything for 1 good turn and 1 chance. 

Once the fight begins as draconus said, you need to start trying to hold onto speed or altitude wherever possible, and depending on what you're trying to do like lead or pure pursuit you are trading PE or KE to do it. Generally the PE you started with is pretty much what you've got to work with as if you try and level the wings and go up you risk giving the bandit an easy angles problem. Going downhill during a sharp turn will help maintain the circle so long as it's worth it. If you find yourself fast for some reason then instead of using the brakes or throttle, then as Dragon says, you could bank that energy by doing a yo-yo or something rather than just throwing it away like your opponent just did.

There's no simple answer to winning dogfights, but if you understand your best rate / radius turns and can do those, and you know your basic aerobatic manoeuvres, then start combining them depending on what you and the bandit are doing. It's fairly normal for new pilots to start thinking very horizontally and to master the vertical later, but there is always something to learn and its a very very currency driven skill.

Thank you all guys! Much appreciated all ideas and advices!!!

Also have a gameplan for each enemy aircraft type you encounter. Know what strengths or weaknesses you can deny or exploit in both your opponents jet and your own. Fuel and ordnance weight will also factor into what you can achieve so keep these in mind.

For example, in an F-14B vs a MiG-29 choosing a 2-circle fight is not usually a great idea as under most circumstances a good MiG-29 will at least match or better your best turn-rate; this means a 1-circle is probably a better option...

However, this generally means you'll need to get slower than the bandit and you'll be sacrificing kinetic energy to do so at the merge. A smart driver will use the vertical to drive their speed down to their best radius speed whilst using a gain in altitude to gain PE and mitigate the overall loss in energy. That said, if you can get your nose on faster, you can drive bad decisions from the opponent, which if you are able to expolit can compound their problems and allow you some good follow-on BFM options, if not an immediate weapons employment opportunity.

For this, a good general purpose piece of advice is "take the fight where the bandit can't follow". In the Tomcat, it usually means into the vertical. There are some opponents, like the Viper, where it can means slow (but slow is always risky, and the only way to get there is through his corner speed), and for a MiG-15 it can mean so fast that his ailerons lock up. Once you get there, you just have to figure out where the bandit decided to be instead of staying with you (all his options are bad at this point), then go down there and kill him, now armed with plenty of spare energy and probably decent angles, as well. If you mess up, go back up and try again. Just make sure not to break the wings (often a risk, particularly when you're coming into the merge supersonic from a Sparrow fight) or run out of gas.

The Tomcat especially favors flying “The Egg” as described in Fighter Combat: Tactics and Maneuvering, Shaw. 
 

Never throw away speed to turn, always convert it to Altitude.  Because you can always cash the altitude back out. 
 

FBW fighters let you cheat the egg by (mostly) not letting you scrub speed. They’ll always try and give you “best turn” without an accelerated stall when you pull all the way. 
 

The Tomcat will let you pull it all the way into the stall, while turning all your speed into Noise and Drag. Especially with a game joystick.  (The real plane has ways of making full aft stick very difficult)

Lots of good advice. But perhaps a bit too complicated. there are several excellent videos on YouTube that will go into this in great detail and with proper terminology.

I’ll assume you’re fairly new to flight, welcome its a great place, so I’ll give you some pointers without terminology and with simplifications. This is not a proper lecture and I’ll skip a lot of things, but here’s how you can think about this before you take the time to learn it the basics:

First of all, it’s going to depend on what tomcat you fly. The A is quite weak, but the B is a rocket ship. If you’re flying the B then going full AB while getting as close to 0g as posssible for a few seconds should be all you need to regain speed  

There are three types of energy: your altitude, your speed and the chemical energy in your fuel that can be converted by your engines. 

Remember Newton’s first law: Your plane would like to continue in a straight line unless forces are applied (gravity is always applied, but other than that it’s up to you). The only force you can apply has its source in your energy state. That means you’ll loose energy every time you change direction. 

Thats OK though, because your engines keep turning chemical energy into kinetic energy (speed). As long as the amount of energy you loose from changing direction does not exceed the amount you get from your engines, you’ll keep your energy. 
One of the great tricks (which at least I find much harder in DCS than in real planes) is to turn without loosing to much energy.

Might be helpful to think of a car. You can make quite a sharp turn and keep much of your speed, but if you do it too much you’ll lose grip and loose a lot of speed. Same with planes: If you pull your stick to hard or to fast, you can end up «drifting»  too much. I think anyone who as flown a fighter or acrobatic airplane will tell you that you can feel this happening. Not so stationary in a simulator. However there are plenty of cues in the tomcat, and you can always look at the AOA meter as well. If your aoa is too high, you can bet you’re bleeding a lot of energy. Now, there’s a lot more too this, not to mention how you blend your stick and rudder controls, but focus on that as a start. The rest you can learn when you feel more confident. 
 

There are one more thing you’ll need to consider: Altitude. If you’re 3000 feet above someone, you have a lot of potential energy that can be converted to speed. That means you can turn harder than your opponent. You will bleed off speed, but you can recoup that better than him since you have more altitude you can trade for airspeed. 
We therefore like to think of a planes energy as a combination of speed and altitude. How you manage that is key. For example, if you are going to fast, you can trade some speed for altitude, thereby preserving energy. 
That’s why most evenly fought fights tend to go downwards: To match the opponent’s turn rate both will trade altitude for speed until they run out of altitude. 
 

This is extremely hard, and you’re trying to play 3D chess against an opponent at the same time. Don’t be too hard on yourself if you struggle, a lot of real pilots had it the same way. And they knew (or should have known) all the theoretical framework before they ever tried it.

I get around this by going full forward trim on entering BFM.  Stops me from getting that last bit of up elevator and means all I have to do is relax pressure to get the "nose down" to speed up.
