After the fighter goes back, it may make a series of flights, but every time it flies, there will be a one-time loss of consumables.

This is also the purpose of bringing Qin Feng here before departure.

Originally, he wanted to coordinate, but Qin Feng actually negotiated it himself.

"Let's go, let's go with me to change into a flight suit first." Mustafa said: "Today there is a routine flight training, one of the MiG-21 pilots Alexander is sick, you use him, you are my wingman, and we go around the sky." ”

"Okay." Qin Feng was upside down.

Although it is said that it can fly, flying is different from flying, for example, there are also coach-type ones here, which take you up to the sky and fly down, at most let you touch the operating stick a few times in the sky.

And now like this, flying a fighter alone, that's another matter, that's absolutely incomparably trusting.

"Alright, let's put on a flight suit." Soon arrived at the flight preparation room, Colonel Mustafa opened the cabinet, and there was a flight suit inside.

Wait, what's that?

Qin Feng looked at the big white guy inside with a surprised gaze.

If you are a motorcycle enthusiast, you should know that in the summer, it is warm, as long as you wear a half-helmet, cover your head, and go down with goggles, just cover your eyes, and the lower half is empty, which is more comfortable.

In winter, when the weather is cold, or riding a motorcycle for a long distance, you have to wear a full helmet, like a bell, if you cover it, the whole person's head is covered, and even the neck can not be exposed, which is particularly warm.

But at the same time, the line of sight is also very narrow, so there are still people who like to run naked, wear nothing, and then go to drag racing on the highway.

Now, in front of Qin Feng, there is such a white full helmet, how uncomfortable should this thing be if it is covered on his head?

Qin Feng had never worn a flying helmet before.

That's right, the Han Kingdom does not yet have a flying helmet.

The pilots of the Han Kingdom, starting from the flight J-5, have been wearing suede flight caps, wearing this kind of flight caps, and then holding the windshield in front of the cockpit to take pictures, which is majestic.

They have been using this flight cap all the time, simple, sturdy, comfortable, flying helmet?

The first domestic flight helmet is the TK1 high-altitude sealed flight helmet.

This flight helmet is an imitation of the ГШ-4 high-altitude sealed flight helmet developed by the Soviet Union in the fifties, and the flight helmet was developed to meet the needs of the J-7 aircraft to perform test flight missions and high-altitude flight missions at that time.

It was only developed in the late 70s, and it was not fully popularized in all air forces at all, and at most it was only equipped with a flight group commander or above.

Moreover, this kind of helmet made of FRP material is too heavy, and even if there is, it will only be worn by pilots with high-altitude flight missions, which is too oppressive to the head, and everyone still likes suede flight caps.

Now, Qin Feng was dumbfounded, he really didn't want to wear this thing.

And at this time, Mustafa had already begun to quickly change into a flight suit, so Qin Feng couldn't delay any longer, whatever he cared, as long as he could fly, he could wear anything, as long as it wasn't green, it didn't matter what hat he was.

Soon, the VKK-3M gravity suit was put on his body, and then, Qin Feng lifted the GSh-4 helmet and put it on his head.

Well, it's not very heavy, and the sight is okay, but it's just that this thing is always not as convenient as a flight cap.

"Hey, why are you wearing it now? Wear it again when you get on the plane. Colonel Mustafa said strangely, muttering in his heart, could it be that the Chinese Air Force does not have helmets, and is it so exciting to see helmets?

made a big joke, Qin Feng hurriedly took off his helmet.

In China, it is to wear a flight cap, so when wearing a flight suit, it is a flight helmet, after all, it is bulky, and pilots carry it and wear it when they get on the plane.

Qin Feng took off his helmet and looked at Mustafa on the side, his helmet looked much smaller, not a full helmet.

Seeing Qin Feng paying attention to his helmet, Mustafa said: "I'm flying a MiG-23, and my cockpit is fully pressurized." ”

The MiG-23 is advanced, and in this respect, it is better than the MiG-21!

Because the MiG-21 does not have a full-pressure cockpit, it is necessary to use this high-altitude flight suit to give the pilot enough living environment, while the MiG-23 has a more advanced pressurized cockpit, so it can wear a lighter VKK gravity suit, carry a lightweight ZSh-3 helmet, hang a KM-32 oxygen mask, and the two of them went in the direction of the runway.

In general, few MiG-23 and MiG-21 flew in formation, and now, in order to take their brothers flying in foreign countries, two fighters are docked at the end of the runway.

In fact, this is also to show the delegation, let them test fly the MiG-21MF, and at the same time observe the MiG-23MS up close, they are quite enthusiastic about the Chinese guests.

Qin Feng stepped into the cockpit, put on his helmet, and began to look at the instrument in front of him.

That's right, all the instruments, buttons, are similar to the J-7, and thanks to the Soviet flight engineers, they don't care about any ergonomics, they are engaged in a dragon, if you fly any of the MiG-21 models, then, fly something else, you don't need to refamiliarize yourself with the instrument, it's the same.

Except that the radar is a little different, there is no other difference, this radar, Qin Feng doesn't need to move, anyway, his plane is not equipped with missiles, this time it is just a test flight, in ordinary flights, there are generally no missiles.

"024, attention, I'm 003, please follow me and take off." Colonel Mustafa's voice came from inside the headphones.

"024 Roger." Qin Feng replied in fluent English.

The roar of the engine was heard behind him, and the P-13-300 turbojet engine of the Tumansky Design Bureau had already been started.

Turn on afterburner!

Seeing that the MiG-23 was already in front and slid onto the runway, the blazing lilac tail flame was what it looked like to turn on the afterburner, and Qin Feng also unceremoniously turned on the afterburner.

Although this will consume the precious life of the engine, I was originally here to test the performance of this aircraft, and of course I have to take off with afterburner.

Brakes were released, the engine in the tail burst out with a thrust of 64.72 kN, and the MiG-21MF slid along the runway.

The first feeling has been that the engine thrust of this aircraft has increased, but it seems that it is not as good as the acceleration of its own J-7II?
