Tap them at the apex of a turn, during a turn fight.

If you need to get advantage in a turning fight, drop combat flaps for a second. It will help you make a tighter turn...or if you need to quickly change height without gaining too much speed - nose steep down, 0 power and combat flaps (ie. when chasing FW190 in a dive in La-5). This is what I usually do and it works pretty good.

There are a few situations where use of flaps is required. Contrary to popular belief, it is not much used to aid handling or maneuvering itself, but rather, as a by-product of killing speed and increasing the stableness of the plane for temporary usage.

What the flaps do, is lower your stall speed(meaning, you can drop to lower speeds than the normal stall speed, and still maneuver), thus, stabilizing your plane. The lift factor from the flaps, are generally not enough to compensate for the loss of speed via drag it creates(with the exception of the "Butterfly" fowler-type flap mounted on Japanese planes), so it will not aid turns, in the technical sense at least.

But the usefullness comes from the fact that, turn rate is not just about the plane itself.

Planes flying in high speed have their elevator efficiency reduced, and it also has to fight against the centrifugal force while turning. So, even if a certain plane has better turn performance, when it is flying too fast, it may be out-turned by planes that have worse turn performance.

Thus, when you engage combat flaps during a merge, it will kill your speed - which will increase your elevator authority, and at the same time lower the centrifugal force working against you. Thus, the plane will pull a tighter turn radius.

However, using flaps during a turn is a double-edged sword, as the enemy, if smart enough, can use it against you. You are killing the essential component needed for combat - speed - while engaging flaps, for the sake of a tactical advantage at hand. So, if your ploy fails, then your loss of speed will work against you.

Thus, usually flaps during turns, are used in limited occasions. One such instance: You see an enemy plane, and he doesn't notice you. You are approaching at much faster speed than he is flying, in a something like 90 degrees angle. As you merge by means of a lead turn, you might overshoot the enemy due to your speed. In situations like this, lower throttle, deploy combat flaps, and pull a lead turning merge to his 6 O'c. Time it right, and you will end up behind him about 120 meters, speed is about the same as him, which will give you a perfect shooting opportunity, since you don't have to worry about colliding.

..

Ofcourse, there are more complex use concerning the flaps. The largest instance of constant flap usage, is during flat/rolling scissors. Scissors maneuvering - be it flat, or 3-Dimensional rolling scissors - , is essentially about turning in to the enemy while going slower than him. It is about who goes slower, and turns tighter, without stalling.

The key to this maneuver, is to reduce your speed slower than the enemy's, but keep it high enough not to stall. Thus, use of flaps come in handy during scissors. The flaps will kill your speed, and at the same time, lower your stall speed.

Rolling scissors, is usually engaged towards the direction of the ground. Two planes engaged in a rolling scissors fight spiral down, lose alt, while each of them trying to over shoot the other. In this case, engaging flaps will keep your speed at bay, so you don't accelerate too much, and be overshooted by the enemy. Very often it takes more than just combat flaps to do this.

...

Also, there are other instances when flaps may come in handy.

For instance, when you are low, and hard maneuvering has caused your plane to snap over.. sometimes, when you overcompensate for the snap-rolling stall, the plane becomes wobbly and out of control, in a very unstable manner - Your plane wobbles to the left, you move the stick right, then the planes starts wobbling to the right. Very often, inexperienced pilots get confused and start to panic when this happens, ultimately crashing to the ground.

Simply, in that case, engage flaps 1 or 2 notches, and let the plane balance itself out. Regain speed, pull flaps back up.

Another instance, is when initiating a very low-alt Split-S maneuver, or when your plane heads maneuvers towards the ground and it looks like you don't have enough room to recover.

In those situations, lower throttle all the way back, engage full flaps and pull as hard as you can on the stick without stalling it. When you plummet to the ground, your plane accelerates quickly. If you pull the stick to recover, you may go into an accelerated stall.

Thus, by lowering throttle you minimize acceleration and speed, enabling the plane to turn a tighter radius, and lengthen the estimated 'impact' time to the ground. With full flaps, you stabilize your plane, and slow it down even more, pulling even more tighter radius. If you are lucky, you just might survive and miraculously pull out of a dangerous low-alt move.

..

Other than this, I can't think of any more instances I use flaps...except landing and take-offs.


..

Oh, when one side of your plane's wing blows a hole due to enemy fire, full flaps can stabilize the plane just enough to manage an emergency landing. The drag caused by the flaps will force you to land quickly, but the extra lift portion of the flaps will redirect someof the lift to the flaps, thus,weakening the wobbling on the roll axis.

When you get a hole in your wing, and it starts dipping the wing, head back towards base, and then engage full flaps, and gently put her down on the field.

In IL2, I loved using them with bf-109s I found I could turn with Ivan easy. In FB, Im not sure, they are not as responsive and the horn drives me nuts!!!
