The great civilization that Europe was able to give birth to is also inseparable from the environment here, with a pleasant climate and a large number of rivers, on which almost every country's capital is built.

Where there is a river, there will be a barrage, and this third turning point is a dam.

In peacetime, the dam can store water to generate electricity, can resist floods, is a great project of human beings to transform the natural world, and in wartime, the dam will also become a terrible nightmare, once the dam is blown up by the enemy, then the downstream will be flooded in an instant.

Now, Qin Feng wanted to conduct a simulated attack here.

Qin Feng just wanted to test how this simulated attack should be carried out if he hadn't prepared in advance.

The existing domestic J-6, J-7 and other aircraft, although the main task is air combat, but when needed, of course, can also hang bombs, ground attack, compared with the Qiang-5 specializing in ground attack, these fighters can only use ordinary shooting sights.

This is a complicated mode of operation, and it is necessary to calculate the "transcendence angle" when dropping the bomb according to the altitude, speed, and dive angle when dropping the bomb in advance, and the "transcendence angle" can be determined by using the angle knob of the sight.

At the same time, even if the meteorological conditions are determined in advance, the amount of correction is calculated according to the wind direction and speed in the area where the bomb is dropped, and then the aiming point and trajectory are finally determined, and after the flight has passed, the meteorological conditions may change, and at this time, the accuracy of the bomb is very low.

What's more, there is also the pilot's aiming error, so the conventional bomb delivery method using the shooting sight has a large error and complicated action.

This is still a case of foreknowledge in advance, and on the battlefield, many times it is temporary, discovering the target, flying over to drop the bomb, at this time there is no preparation, relying entirely on the pilot's own experience, and the error is even greater.

Qin Feng knows the trick very well, it is difficult to use his own equipment to drop bombs, and if he wants to improve his accuracy, the best thing is to dive and drop bombs.

Even in World War II, the dive bombs of German pilots can achieve the same accuracy as the laser-guided bombs of later generations, but in this way, it requires the pilots to pay great sacrifices, after all, the ground is all anti-aircraft fire, and diving down is simply dancing on the tip of the knife of death.

At that time, it was just a propeller flight, but now it has developed into a jet machine, which has a lot of speed, and dives to drop bombs, and if it is not pulled up in time, it will hit the ground and turn into a big fireball.

Now, just to try the on-board system of the Mirage 2000, Qin Feng began to prepare after receiving Colonel Mido's lazy answer, and he operated the transfer switch of the weapon to transfer the head-up display to the CCIP method.

As the name suggests, CCIP is an on-board device that constantly calculates every impact point, similar to a cannon hotline.

Now, when the conversion passed, Qin Feng saw that the interface of the original navigation information had disappeared, and an aiming line appeared under the speed vector of the flat display in front of him, and there was a circle at the end of the aiming line, needless to say, where this circle was trapped, it meant where it could be exploded.

As for the flight conditions, the local wind direction and wind speed, and all kinds of correction relationships, you don't have to think about it yourself, all you have to do is one thing, to trap the target.

Of course, if he wants to trap the target, then he must dive, so this is also a kind of dive bomb.

Qin Feng pressed the operating stick, and the Mirage 2000 fighter began to dive downward, and at this time, the aiming line was pressed on the barrage, which showed that the aircraft's course was fine.

As the plane flew forward, the target was moving along the line of sight, getting closer and closer to the circle.

Qin Feng held his breath, if this was a battle, then Qin Feng would easily and accurately drop bombs at the target at this time.

Getting closer and closer, getting closer and closer, when the target moved to the circle position, Qin Feng's hand pressed the bomb drop button.

There are no extra buttons, on the joystick, there is only a red launch button, no matter what weapon is used, this is the button.

It mainly depends on the selection switch, put it on the cannon, that is the cannon firing button, put it on the missile, it is the missile launch button, if it is a bombing option, it is the bombing button.

But this time it was a simulation, so when Qin Feng pressed the button, nothing happened, the fighter pulled up and flew over the barrage, Qin Feng could even see that on this side of the barrage, there were some people fishing, and when they saw the fighter, they waved to the sky.

Qin Feng looked at the people below, and sighed in his heart, for the French, they are proud, no matter when, the French will not bow their proud heads, because they have a strong national defense, all their weapons and equipment, they can produce themselves, only a strong national defense industry, can have a strong army, and can also have a strong national self-confidence and sense of honor.

With this in mind, Qin Feng switched the heads-up display back to the navigation interface, and then reached the fourth turning point, followed by the fifth.

In the past, Qin Feng's understanding was not in place, and he felt that he could use the head-up display to realize the hot-line aiming of the cannon, which was already very powerful, but now he knew that this was only a small part of the performance of the head-up display, and the potential of the head-up display was huge, so to speak, it was a good assistant for the pilot.

In addition to a cannon hotline, there are normal flight data, navigation, bombing, missile attacks, etc., all data are realized on the heads-up display.

Therefore, Tu Lao withstood the huge pressure to achieve the J-7 flat display, which is a huge progress, although there are no other functions, but as long as the problem of existence is solved first, it will continue to expand in the future, so that this system will blossom everywhere on the fighters developed in China.

Qin Feng thought secretly in his heart.

The fifth turn!

The last turning point, Qin Feng looked down at the past, and simply made it clear that he had been flying for an hour, and now the difference between the navigation and the real value below should not exceed five hundred meters, such an accuracy is quite high!

In the past, I didn't know how much pre-flight preparation I had to make, but as a result, the sky was not beautiful, and a simple cross wind could make me yaw, or even yaw too much to find a destination, but now? Just enter a few sets of data and plug in this plug-in card, it's so convenient!

In the airport, there were already people waiting on the runway, everyone watched the fighter plane return, and when it landed, a simple check, the whole flight took 1 hour and 20 minutes, and the error of the navigation system to return home was 0.7 nautical miles!
