Chapter 19 Air Traffic Control's Doubts

After dinner, Lin Dong took Xu Qingling to the laboratory.

Upon opening the laboratory door and seeing the model drones gleaming under the lights, the little girl couldn't help but exclaim in amazement.

"Lin Dong, is this your plane? It's huge!"

With a wingspan of over two meters, a length of over three meters, and a height of nearly one meter, coupled with sharp and rugged lines.

When a primary school student stands in front of such an aircraft, she is immediately overwhelmed with a sense of awe.

"..."

Lin Dong didn't answer Xu Qingling's wild words. He moved his laptop to the side of the laboratory door, plugged it in, turned on the avionics system, and then connected the antenna and analog control equipment with an anti-interference high-speed communication cable.

Di-

The system performs a three-second self-check and then enters the model aircraft flight control interface.

Lin Dong told Xu Qingling to move away, and then started the model airplane.

Since Wang Rui's three oxen and horses weren't there, and no one was going to push the model airplane out, he decided to start it up inside the lab and then let it glide out.

hum!

Rumble!

The starter motor drives the intake fan blades, and after running for a while, the two small turbofan engines spew out two plumes of black smoke, and the next second they enter a high-speed and stable operating state.

"Xu Qingling, don't come any closer."

Lin Dong shouted, released the brake, lightly pressed the accelerator, and simultaneously adjusted the servo angle.

As the engine accelerated, the model airplane parked in the lobby slowly completed a circular turn and then gently glided out of the gate.

Lin Dong checked the remaining fuel level, opened the test flight application interface under the laboratory, and began to fill in the test flight application and test flight route.

"Lin Dong, what are you doing?" Xu Qingling waited for a while and saw that the model airplane had not yet accelerated to take off, so she walked over curiously.

"Apply for a test flight permit."

"You absolutely can't fly illegally in this game, or you'll get shot down and have nowhere to cry."

Lin Dong introduced Xu Qingling to some aviation regulations and precautions for aircraft.

Because there are almost no survivors in aviation accidents, any aircraft taking off must obtain permission from air traffic control and follow its instructions.

However, the military has its own air traffic control and dispatching system, and civil aviation has its own air traffic control and dispatching system.

Although his model aircraft and drone belong to the military industry, if he wants to leave Chengdu Aircraft Industry Group's exclusive test flight area and fly a little further away...

An application still needs to be submitted to air traffic control so that air traffic control can identify the aircraft and manage it.

If a test flight is conducted without an application, it's because there's no application or scheduling record.

At best, they might be mistaken for spy planes and shot down; at worst, they might accidentally fly into civilian air routes, causing air traffic control to fail to detect them in time, resulting in an aviation disaster such as a collision between passenger planes.

"beep--"

Lin Dong filled out the application form and submitted it less than ten seconds later.

Suddenly, a call was automatically connected to the application interface, and a female voice speaking standard Mandarin came through.

"Hot 001, hello, this is air traffic control C987."

I see that your aircraft just completed a test flight from Chengdu to Yunnan this afternoon. Are you now applying for a second test flight?

"..."

Lin Dong was stunned.

Xu Qingling, who had just been excited and wanted to move a small stool over to sit down, suddenly froze.

"Lin Dong, what should we do?"

Xu Qingling gripped the small stool with both hands, mouthing a question, her bright eyes filled with nervousness, looking just like a child caught doing something wrong.

Although she didn't quite understand the application and inquiry process, she knew that at this point, as long as they dared to speak up...

Given their childish accents, the air traffic controllers on the other side might call the police on the spot.

"Hot 001, can you hear me?"

The air traffic controllers on the other side waited for a while but didn't hear a response, so they asked a second time.

"Ahem, I'm here!"

Seeing that he couldn't delay any longer, Lin Dong coughed twice to clear his throat and managed to squeeze out a hoarse voice: "The flight data has been updated, and we plan to conduct a second test flight to verify the data."

"You...you have a cold?" The person on the other end paused for a moment, then couldn't help but ask.

My throat feels a little uncomfortable.

Lin Dong forcefully controlled his voice, avoiding excessive changes in tone.

The air traffic controllers on the other side listened to the sound and clearly fell silent, waiting a while before responding.

"Okay, Hot001, your application has been approved."

"The test flight airspace starts from Chengdu Aircraft Industry Group base, travels in an east-southeast direction to the Guangdong provincial border, and then returns at an altitude below 8000 meters."

Please strictly abide by aviation regulations to ensure stable flight routes. If there are any route changes or other issues, please contact us promptly.

"Thanks."

Lin Dong thanked him and quickly ended the call, switching to the model aircraft flight control interface.

"The test flight application has been approved. Begin the test flight!" Lin Dong gestured for Xu Qingling to sit down, opened the throttle valve, and pushed the accelerator.

boom!

Two streaks of azure flame shot out from the engine nozzle, and the entire model drone shot out in a violent gust of air.

"take off!"

Lin Dong pulled the control lever and slammed the pedals down.

The nose of the model drone tilted up. It took a sharp climb after traveling less than 100 meters.

It shot into the sky at a near-vertical angle, circled halfway, and then locked onto a direction slightly to the southeast before flying straight away.

"Wow! That stance and speed are amazing!"

Seeing this takeoff posture, Xu Qingling cheered excitedly.

As a family member of Chengdu Aircraft Industry Group, although still a primary school student.

However, she still has some understanding of basic aircraft attitudes and speeds.

This near-vertical, high-angle pull indicates that the engine power of Lin Dong's model aircraft has completely surpassed the constraints of the fuselage.

"We did a test flight this afternoon, which consumed some fuel and reduced the weight of the fuselage," Lin Dong explained with a smile, staring at the avionics interface.

It features a twin-engine design with a power-to-weight ratio of 9.2 and a total thrust of up to 1270 kg.

The maximum takeoff weight of a fully fueled model airplane is only this value.

By the time the test flight was completed in the afternoon, about a third of the fuel had been used.

Today's model airplanes weigh less than 1000 kilograms, and the ratio of engine thrust to fuselage weight has increased to 1.2.

This thrust-to-weight ratio of the engine to the fuselage means that even without gliding or even the need for wings, the engine's thrust can propel the model drone vertically into the air, making it a perfect example of a fully powered flying brick.

In the core area of ​​the Chengdu Aircraft Industry Group (CAC) base, as Lin Dong's drone took off.

Wang Xingguo stood by the window with his secure phone in hand, watching the model drone streaking across the sky, its tail flame trailing behind it. He pondered for a moment before replying.

"Yes, the test flight number is Hot 001..."

"This is a special aircraft that Chengdu Aircraft Industry Group has recently developed. We may have more frequent test flight missions recently, so please bear with us, Air Traffic Control Bureau."

"The test pilot's voice is hoarse, which sounds strange. Can you confirm if there's a problem? No problem, the test pilot just has a cold."

"This test pilot's voice is quite unique; even as an adult, he still has a childlike voice. But when he caught a cold and had a sore throat, his voice sounded strange. Yes, I'm sorry to trouble you all this time..."
