Chapter 117 Take off is easy and difficult to land
Diving down from an altitude of 15,000 meters, he can easily exceed the speed of sound without using afterburner. Li Zhan enjoyed the pleasure of acceleration and paid close attention to the airspeed and altitude. The ridge of the Beiku Mountains below was 3,000 meters high.
meters above sea level, and the highest peak is over 4,300 meters above sea level.
In fact, the highest peak and sub-peak of the Beiku Mountains are important landmarks. Li Zhan knew the location of the main peak very well. The simulated target was this peak. He simulated attacking the peak to complete the ground attack and then left. Such an obvious target must be challenged.
As for the challenge, I can only say that if you are extremely stupid, you may hit the mountain.
There was no suspense, the attack was crisp and clean, he turned left and pulled away without any delay. Li Zhan controlled the altitude and flew back at a low altitude in the Beiku Mountains.
High-altitude attack, low-altitude return, standard ground attack mode. If you switch to su-27, su-30, J-11 or J-10, it is obviously more comfortable to play this skill. For those who emphasize high altitude, high speed, flexibility and lightness
For the J-7, which is designed for close-range air combat, it is somewhat inadequate.
Air Force pilots should have the spirit of daring to be the first in the world. The J-7ii fighter jet is the first J-7 variant with night combat capabilities. It is also the first variant with the ability to shoot thunderbolts and rockets. Although many times
Don't know where to hit the thunderbolts.
Since you have this ability, you must dig out the corresponding combat power.
Although he was mentally prepared, when the No. 01 fighter jet disappeared from the radar, Xue Xiangdong's heart still involuntarily rose.
He sighed and said, "It would be great if there was an early warning aircraft."
Li Zhan flew at low altitude among the mountains as planned, using the obstruction of the mountains and the curvature of the earth to cover his return, which meant that he would be out of the detection range of the radar. Because of the curvature of the earth, it is difficult for the radar to detect low-altitude targets. In order to solve this problem, people
The radar was moved to the aircraft, and the radar's reference altitude was raised. The detection distance of low-altitude targets was greatly increased and became more precise, so there was an early warning aircraft.
"We have that thing, but we don't know how long it will take to get it here." Yang Jinshan said, "He flew at low altitudes in the mountainous areas many times to fight the floods in Sanhe, and the weather at that time was even worse than now, so there will be no problem."
"How did the J-8 he drove fall apart?" Xue Xiangdong asked with a frown.
Yang Jinshan said, "According to the notified investigation report, the intensity of use exceeded the standard. Ba Ye is still quite strong, but unfortunately he cannot withstand such high-frequency overload use. He flies at supersonic speeds with full load and afterburner, and also performs large overload maneuvers.
, with the weather like that at that time, anything could happen."
"A new plane that was less than half a year old is gone like this. What a waste." Xue Xiangdong shook his head helplessly.
"Captain, he has made a great contribution." Yang Jinshan said with a smile, "At that time, the flood control situation in Sanhe was very critical, and tens of millions of people in the middle and lower reaches were facing threats. He flew two sorties, braving heavy winds and heavy rains, to attack the upper reaches.
The natural lake was repeatedly bombarded with precision, blasting open a section of the mountain and channeling the floods away. The flood-fighting pressure on the middle and lower reaches suddenly dropped sharply."
Xue Xiangdong nodded slowly, "That's right, no one is perfect. Having said that, if you want to make great achievements, how can you do it without paying something? Compared with the safety of tens of millions of people's lives and property, a mere J-8 is still
It’s really nothing.”
Yang Jinshan couldn't help but laugh and said, "I heard that the J-8 was provided by the manufacturer to the Second Division for testing. A total of two were provided, but the army did not pay."
After being stunned for a moment, Xue Xiangdong laughed loudly, "It seems that this kid is not all bad luck!"
Although the two tried to relieve the tense atmosphere in this way, not only were they still so nervous that they seemed careless when talking, the other personnel on duty in the tower also looked solemn and stared intently, especially the radar operator, staring at the display screen.
I can't wait to teleport to Li Zhan and raise the lever for him.
Perhaps the calmest person is Zhang Yuan.
In order to ensure this combat training under complex weather conditions, he came to the tower as the technical deputy director to personally work and pay close attention to weather changes. He knew very well that even if something happened, Li Zhan would fly back safe and sound, so there was nothing to worry about.
.
Thinking of this, Zhang Yuan subconsciously smiled slightly. This scene happened to be seen by Xue Xiangdong, so Xue Xiangdong walked over and asked in confusion, "Xiao Zhang, how is the weather? You look very relaxed. Is there any good news?"
"
It seems inappropriate for the main group to call the deputy group Xiao Zhang. However, Xue Xiangdong is about ten years older than Zhang Yuan, so it doesn’t seem inappropriate to call him Zhang Yuan Xiao Zhang. In short, no one present felt that it was inappropriate. Zhang Yuan
I didn't feel inappropriate either.
Xue Xiangdong's prestige in the 101st Regiment and even Beikuchang Station is too high.
Zhang Yuan quickly replied, "The weather will continue to get better, but today it is almost unchanged. I don't know if this is good news."
"Well, very good. The work of your meteorological department is very important. Whether you can fly or how you fly depends entirely on you." Xue Xiangdong nodded slightly.
Zhang Yuan smiled bitterly and said, "Commander Xue, don't worry, this kind of weather is really nothing to Li Zhan. He has flown in even worse weather conditions than this, many times, and he is very experienced."
"I believe in him, otherwise I would not support him in conducting complex meteorological training." Xue Xiangdong said insincerely, feeling very aggrieved.
"Report! The cave has appeared!" the radar operator reported and injected everyone with a stimulant.
Xue Xiangdong came over like a wind and stood behind the radar operator. Yang Jinshan picked up the transmitter and handed it to Xue Xiangdong. The latter called Li Zhan, "Dong Yao Dong Yao, the tower called, received the answer."
Amidst the electromagnetic interference sound of "buzz", Li Zhan's voice was calm and said, "Dongyao received it. The radar has confirmed my position and attitude. My horizon has been interfered with. It's over."
The direct-reading gyro horizon is in the most conspicuous middle position of the instrument panel. The pilot can see it intuitively when he opens his eyes. The horizon is an instrument that indicates the pitch and roll status of the fuselage, and it is extremely important. Whether it is a second-generation or third-generation aircraft
Even for fourth-generation aircraft, or passenger aircraft no matter how advanced civil aviation is, the horizon is an extremely important indicating device.
However, when the sensing element of the device is subject to strong electromagnetic interference, it will produce a large error value. What's more, the performance and reliability of the horizon instrument equipped by the J-7ii can no longer match the performance and reliability of the horizon instrument installed on the current third-generation aircraft.
compared to.
The magnetic field in mountainous areas is chaotic and it is normal to receive some interference.
The radar operator immediately confirmed the specific position and attitude of the No. 01 fighter. After Xue Xiangdong reported the relevant data to Li Zhan, he ordered, "Dongyao, maintain the heading altitude and return as planned, completed."
It was confirmed that the horizon instrument was indeed interfered with and had large errors and lags. Li Zhan did not dare to take it lightly.
He looked from both sides and saw that the visibility was very low. This was not a good sign. He said, "Tower, I encountered heavy fog. Apply for altitude. Complete."
"Dongyao, keep at six thousand, call at thirty kilometers, end." Xue Xiangdong commanded as expected. He was so happy that Li Zhan made the right choice instead of insisting on continuing to fly at low altitude.
"Understood, hold on for six thousand, it's good to scream for thirty kilometers." Li Zhan immediately pulled the lever and climbed up.
Heavy fog in mountainous areas is a killer for fighter planes. Visibility is less than one kilometer. Fighter planes are shrouded in fog and the pilots cannot see anything. However, it is more of a threat than turbulence. In addition, the horizon instrument has a large error due to interference, so it is difficult to head up the mountain.
The probability skyrocketed.
Just because Li Zhanyi is brave doesn't mean that he lives an impatient life with a cramped brain.
He once again passed through the clouds and reached six thousand, flying almost close to the top of the clouds. He looked around and did not see the thirty-kilometer landmark Xiaobeiku Peak. The so-called thirty-kilometer landmark means that when you reach the landmark
Above, it is about 30 kilometers away from Beikuchang Station. Xiaobeikufeng is the second highest and sub-main peak in the northeast of Beikuku main peak, with an altitude of over 4,000 meters. In other words, the peak of Xiaobeikufeng should be
It would be better if there are some clouds.
The clouds changed again, covering Xiaobeiku Peak.
In desperation, Li Zhan could only report to the tower and descend again. Fortunately, when he returned under the clouds, he had already passed the foggy area. Li Zhan continued to communicate with the tower to confirm his position and the station.
Location. Even though he was very familiar with the surface terrain of this area, he was almost blinded by the weather and the visibility.
Li Zhan couldn't help but secretly think that he must find a way to get a portable positioning device. If that doesn't work, just buy a civilian GPS locator!
He had no way of knowing his specific location. It was fine when there were landmarks or he could see them, but otherwise he was blind.
Isn’t there a Beidou satellite positioning device?
Everything will be available in the future, but not now. At least Li Zhan, who has flown the J-7 and J-8, knows very well that these two models are not equipped with Beidou satellite positioning terminals, including the J-8fr tactical reconnaissance aircraft. It must be
Use ground radar to confirm your position. Whether you are heading to combat airspace or returning to the battlefield, you are inseparable from the guidance of the ground command post.
It can be said that once the J-7ii in the sky loses contact with the ground, it will be a blind fly and can only fly a few times. This is why Xue Xiangdong and others were so nervous after the radar lost traces of the No. 01 fighter jet.
reason.
Entering 2010, some units of the Chinese Air Force are having a harder time than ordinary people imagine.
After seeing Xiaobeiku Peak, Li Zhan immediately reported it. What followed was a flat basin. After the horizon returned to normal, he no longer worried about hitting the mountain, even if he once again entered the light snow weather with extremely low visibility.
middle.
Li Zhan turned around three times before he could see the runway. Fortunately, the high-power searchlight installed on the weather station had strong enough penetration, otherwise Li Zhan would still have to spend a lot of time finding the airport. At this time, under the clouds, he looked around
It was a gray sky, and although it was no longer as dark as when we took off, the visibility was still very poor.
"Tower, I've lowered the landing gear and prepared to make a three-turn turn." Li Zhan reported.
In the tower, Xue Xiangdong looked at the observer. The first-class soldier was looking for it hurriedly with his telescope, and reported loudly and tremblingly, "Report! I can't see the landing gear!"
Xue Xiangdong suddenly looked outside. The visibility was estimated to be less than one kilometer. He could see the flashing lights of the No. 01 fighter plane turning three, but he could not see clearly the status of the landing gear.
"Dongyao, I can't see your landing gear. Clear the field once and pay attention to altitude and speed." Xue Xiangdong decisively issued new instructions.
Li Zhan replied, "Understood, let's go through it once."
The clearance was to allow the tower to confirm that his landing gear had been lowered normally. Li Zhan did not dare to show off in this regard. In other words, he had some shadows in his heart.
It was very safe to pass through the field, and it was as close as possible to the tower, so the entire fighter plane could be seen at a glance.
The front and rear landing gear had been lowered normally. Xue Xiangdong breathed a sigh of relief and gave Li Zhan the command to land. Li Zhan climbed a little higher, turned around and landed steadily.
Training in night flights and low-visibility weather, and landing are the most critical aspects, especially for these second-generation old aircraft. As long as you find the airport and see the runway, you have passed this subject to a certain extent.
There are two major thresholds for carrier-based fighter jets to board the ship. The first is to take off from the deck, and the second is to land on the deck. On top of this, adding a night flight, the difficulty level skyrockets. Simply put, you can fly as you like.
The pilots who take off and land on the deck are truly the top aces of the entire military aviation force.
There were no dangers along the way, and the combat training in rain, snow and foggy weather personally conducted by Li Zhan was declared a success.
