It's like with GPS, you can't navigate immediately, you have to cooperate with digital maps, inertial navigation is advanced, but if you only have that gyroscope, you still can't do anything, you have to cooperate with other systems.

Now, the one that Colonel Mido is holding in his hand is a plug-in card, which is the same as a USB flash drive, and the data can be read out by navigation by entering data in a certain format, and the data in it provides the latitude and longitude of each turning point, as well as relevant data.

A turning point needs to have 10 data, and such a plug-in card can store 20 turning points, can remember 30, a total of 300 data, so that, plus the data at the time of initial take-off, it can clearly indicate the course of the aircraft.

The two stepped onto the plane, Qin Feng watched Colonel Mi Duo personally insert the plug-in card into the navigation control box on the panel, and then said to Qin Feng: "The number of the turning point has been entered, which turn delay point you want to fly to, press the number button accordingly, and then, according to the head-up display." ”

The heads-up display is powerful, and the head-up display is not only as simple as the hotline aiming of the cannon, but also the data needed can be displayed when navigating.

"Understood." Qin Feng said, pressing the number of the first turning point, and then, Qin Feng remembered something again: "I want to arrive on time, what should I do?" ”

If the two formations converge in a certain area in the air, they must be punctual, if they go late, they will not be able to form a formation with the other party, and if they go early, they will have to go around in circles around that area.

Therefore, the past method is very troublesome.

It is quite tedious to calculate a detailed tachometer, find many checkpoints on the route, and adjust the speed according to the pre-calculated data according to the difference between the estimated time and the actual time at each checkpoint.

And now? Colonel Mido in the rear cabin said lightly: "Whatever." ”

As you see fit? How is this possible?

Qin Feng sat on the seat, and as the engine started, he slowly slid towards the runway as before, and then took off with afterburner, just as he was climbing, he shouted to Colonel Mido: "What is the flight altitude?" ”

"Whatever."

"How fast is the flight?"

"Whatever."

No matter what Qin Feng asked, Colonel Mido was just two words, how could this be possible?

Different heights, different air densities, different resistance, the same throttle lever position, the speed is different, now, no matter what you ask, Colonel Mido said whatever?

Qin Feng originally planned to climb to eight thousand meters and fly in a straight line towards the target in the most fuel-efficient way, but when he heard Colonel Mido's words, he looked full of confidence, and thought that he was originally going to check the accuracy of the navigation system, if he only flew in a straight line, how could he know how accurate it was?

Therefore, Qin Feng was ruthless, simply, just pulled up, he flattened, glanced at the flat display in front, the height was only 150 meters, and then, he turned off the afterburner and entered the level flight state.

In front, the mountains roared, and Colonel Miduo in the back cabin sat on the Diaoyutai very leisurely, watching Qin Feng toss around.

After entering the mountain, Qin Feng increased his altitude slightly, although he really wanted to drill through the mountain, but once he encountered a crosswind or something, if there was an accident, it would still bring trouble, so he flew to the top of the mountain, and then, through the mountain, lowered the height again.

At this time, there is already some more data on the heads-up display, the flight distance, no flight distance, are marked out on the head-up display, in the middle of the head-up display, the most obvious position, begin to indicate the direction of the turning point, the target in the circle at the end of the azimuth line, is the turning point, in this way, the route is left and right at a glance.

Qin Feng secretly sighed in his heart, this navigation system, no matter how you fly, as long as you fly to a certain extent, it will start to instruct.

At the same time, there are two lines of data on the left and right of the head-up display, the actual speed and the command speed.

If you want to arrive accurately, every second is not bad, that is related to the distance and speed, the computer system has made accurate calculations, and now the actual speed is higher than the command speed, then he needs to close the throttle to slow down, otherwise it will accelerate, in short, as long as the speed of the aircraft corresponds to the speed given by the computer, it will arrive on time.

You don't have to think about the distance, the wind speed, etc., you don't have to think about it anymore, and leave it all to the computer to control!

Qin Feng's heart was filled with emotion, and when he saw the first turning point, Qin Feng looked at the navigation watch, almost every second.

In the sky above the first turning point, Qin Feng pressed the button and switched to the second turning point, and now, he could fly towards the second turning point.

In the past, a lot of pilotage calculations had to be carried out, drawing routes on the map, measuring distances, measuring wind speeds, etc., and all kinds of errors had to be taken into account.

This wastes a lot of time and effort.

But what about now? The navigator or pilot needs to do one thing, remember the number of those few turning points, and that's it!

This is actually the same principle as the navigation of later generations, you don't have to care about anything, how to turn the overpass, how to get off the highway, where to turn, you just need to tell the navigation, I want to go here, that's enough, it's that simple and direct.

It's a fool's errand.

Qin Feng flew towards the second turning point, and he was secretly sighing in his heart, is such a navigation system beneficial?

Of course!

For pilots, the main task is combat, the high degree of automation of navigation functions, shorten the pre-preparation time of pilotage, reduce the burden of pilots and navigators, improve the combat response speed of the aircraft and the accuracy of pilotage, in particular, in addition to air combat missions, there are also ground attack missions, this way of navigation, can make ultra-low-altitude flight ground attack aircraft can easily fly to the target airspace, in the past, ground attack mission, is the most test of the pilot, now, to the advanced avionics system, It will greatly improve the combat effectiveness of pilots and fighters.

When the avionics of the Marconi company was introduced, because the platform of the J-7 was too small, so under the advice of the engineers of the Marconi company, the inertial navigation system was not introduced.

Wait, ground attack?

The third turning point, which is a dam, is simply there, for a simulated attack? Thinking of this, Qin Feng's heart was hot: "I request that at the third turning point, a simulated attack will be carried out." ”

"Whatever." It was still Colonel Mido's lazy voice.
