"Which runway do we need to take?" Qian Yu manipulated the joystick, looked at the gyroscope on the dashboard, and asked. "If we end up finding out that we're not on the runway, it's going to be very difficult to deal with."

"There's a long runway in this direction, don't worry." Sadaharu Takamori replied. "As long as you cut diagonally from the coast, there is a long enough main emergency runway."

"Where are we now?" Qian Yu asked a little uneasily. "I don't know exactly where we are, in case we get it in the wrong place......"

"I'll contact the tower, don't worry," Sadaharu Takamori flipped through a notebook in his hand—unlike the JAL manual he had held before, it was entirely his personal manual, which recorded all the details of the Far East's cargo plane landing without hydraulic pressure. "All you have to do now is stabilize the plane, and I'll re-intervene after reading the logs...... By the way, report the speed and altitude. ”

"Speed 270, height 210." Chiba replied.

"That's pretty much it." After Sadaharu Takamori answered, he began to flip through the manual again.

"The speed of the plane may slow down, you should be mentally prepared," Sadaharu Takamori said suddenly. "The good news is that the plane should be slightly easier to handle."

"What are you going to do?" Thousand Feathers raised an eyebrow. "In that case, the plane might be a little bumpy."

"Just put the landing gear down, don't worry," he said, turning a handle as Sadaharu Takamori turned. "Unlike those elements, the landing gear itself has the means to manually put the landing gear by gravity in addition to the hydraulic mode."

With that, he had already done a few things and finally pressed the button to put the landing gear. "Hopefully the hydraulics are almost gone."

"What do you mean?" Qian Yu was stunned.

"I hope there won't be a liquid lock—" Sadaharu Takamori watched the landing gear lights light up one by one, and his face suddenly became extremely ugly. "Damn it!"

On the dashboard, almost all the landing gear lights are on, except for one.

The nose of the plane landing gear lights under their feet did not come on.

"What's wrong?" Chiba couldn't see what was going on, as he was busy dealing with the change in speed and maneuvering patterns that would occur after the landing gear was lowered.

"The nose gear is locked with a fluid lock," Sadaharu Takamori said in a deep voice. "The nose gear can't be put down right now."

"What are we going to do?" Qian Yu asked again.

"I can't handle it." Sadaharu Takamori was silent for a moment, then sighed. "When you land later, I'll deal with it, you hide behind the plane, take your buddies to the back, I think there should be some seats there that haven't been sold, you remember to fasten your seat belts and be prepared for collision."

The take-off and landing of the landing gear is composed of two hydraulic subsystems A and B respectively, wherein the landing gear needs to be the hydraulic pressure in the action cylinder of the landing gear from the A system and give the landing gear to put down space. However, if the hydraulic oil of System A is not released from the return line, but is trapped in the cylinder by the closed flap, the cylinder will become stuck and will not be able to use gravity to slowly release the landing gear into place. As for why the front landing gear and not the rear landing gear are not in place, I am afraid that it is because the front landing gear itself is relatively light, while the rear landing gear is relatively heavy and large, so it is easier to complete the lock by gravity. (The flight technology itself uses a large angle to dive and then pull up, and throws out the landing gear by centrifugal force + gravity.) In this process, the nose gear is basically always the hardest one to throw out, because the cargo is too light to be thrown into a fixed position and snap in. ）

In the current situation, the hydraulic oil of the two hydraulic systems of AB should have leaked with the rupture of the tail, but apparently a small part of it was still trapped in the action barrel and could not be released - and this is a situation that they are completely unable to handle now.

Because the normal response to this situation is to "repeatedly manipulate the flight spoiler to release the participating hydraulics". But how are they, who have lost control, to operate the flight spoiler now?

Thinking of this, the corners of Takamori Sadaji's mouth twitched. "You continue to ensure a smooth flight first, I need to communicate with the purser."

Since gravity alone cannot release the landing gear, perhaps they need to use centrifugal force to throw out the landing gear, and the plane is very bumpy in the process, so it is necessary to communicate with the passengers in advance and ask them to fasten their seat belts.

……

After about two minutes, Sadaharu Takamori ended his communication with the purser and reluctantly picked up the radio phone, which he had wanted to ask the purser to do for him, but the purser told him that he should be the professional to explain it to reassure everyone.

"Guys, I'm Sadaharu Takamori, a DC-10 airliner flight instructor who is currently flying the plane," Sadaharu Takamori took a breath and made his voice feel more mature and reliable. "As you may have sensed, our aircraft is currently dehydrated and cannot be controlled by conventional means, so we are currently piloting our aircraft by unconventional means in order to return to New Chitose Airport. In order to make the flight more stable, we are going to use the gravity toss to try to release the landing gear, during which the aircraft will face quite severe turbulence, so we ask that passengers wear seat belts and prepare a shock-proof posture. As the most elite flight instructor class in DC-10, I have the confidence to lead everyone to create miracles, OVER. ”

After saying that, Sadaharu Takamori glanced at Chiba a little nervously - if you want to talk about danger, I'm afraid only this kid is the most dangerous - the cockpit of DC-10 has a total of five seats, two pilot seats, a random engineer seat, and two observer seats, but none of these seats can be sat on by Chiba now. As long as Qian Yu sat in any position, he would definitely not be able to reach the two throttle valves that could still be used.

"You sit in the captain's seat first, and I'll keep the flight stable." Sadaharu Takamori said.

"Uh......" Qian Yu didn't look back, just made a hesitant sound.

"Don't underestimate me, I'm a professional compared to you." Sadaharu Takamori snorted and said coldly. "And do you know how to do gravity toss, rookie?"

"Uhhhh "Then you just take over?"

"Hmm," sat in the passenger seat, and Sadaharu Takamori took over the throttle valve directly from Chiba's hand. "Sit down quickly, the flight situation after the gravity toss is over can be complicated, you need to take over as soon as I stabilize the situation, and then keep the flight smooth, I need to check the landing gear and make a plan for the next flight.
