In view of Xu Wei's almost perfect landing performance, although Xu Wei himself felt that it was mainly the instructor's credit, after taking off, the instructor gave Xu Wei a few more ** photos, and the cockpit was filled with lewd and obscene laughter, and slowly, Xu Wei also felt that brown skin was not so unacceptable.

The rest of the time was running out, and the instructor gave up the intention of doing another flight maneuver during the course of the voyage and flew straight to Athens.

The journey was relatively leisurely, the instructor was in a good mood, and as a result, the plane was controlled, and the gas pedal began to climb. Xu Wei didn't know what the instructor was going to do at first, the original 4000 feet should be suitable as a cruising altitude, if you climb up, you need to climb to 6000 feet, but this doesn't seem to make sense, 4000 feet is at this altitude and there are no clouds to avoid.

Again, the FAA regulations stipulate that the visual cruising altitude depends on the heading. The heading is 1-179 degrees, the altitude must be odd thousands of feet, such as 3000, 5000, 7000 feet, the aircraft is only allowed to fly at these altitudes, otherwise there will be a risk of collision, the course is 180-359 degrees, choose even thousands of feet, like 4000, 6000. Xu Wei's heading is 273, so the cruising altitude of 4000 feet is no problem, and it is not to avoid clouds, and the ATC has no instructions, what does the instructor want to do?

Today's density altitude is very low, the flight performance is extremely high, and the plane climbs very quickly, 5000 feet is in the blink of an eye, and 6000 feet should be reached in a minute.

At an altitude of nearly 6,000 feet, the air blown out of the vent was already relatively cool, and Xu Wei breathed the air at high altitude for the first time, cool, refreshing, a bit like the air after the snow in winter.

The plane quickly rose to 6,000 feet, Xu Wei thought that the instructor was going to change the level, but he didn't mean this at all, he didn't reduce the throttle, nor did he press the nose, but directly crossed the height of 6,000 feet and continued to climb.

Xu Wei was stunned, he was really confused now, did he still want to climb up?

“whyyoukeepclimbingsir?” Xu Wei finally asked.

“nothingjusttoohotinlowlevel.” The instructor laughed, "Takemoreclothesnexttime."

Xu Wei had a few black lines on his forehead, he was wearing a short-sleeved uniform, and he was already feeling cold at more than 5,000 feet, and it was definitely colder up.

At this time, the instructor suddenly said: "hugowhatisaltitudelimitforc152?"

Xu Wei recalled and blurted out: "Shouldbe12000ft." As soon as he finished speaking, the corners of Xu Wei's mouth twitched a few times, he didn't want to climb to the ceiling height, it would be very cold there, and there would be a lack of oxygen, bastard! Xu Wei kept complaining in his heart, but he still had a surprised expression on his face, as if he was really interested in the height of 12,000 feet.

Seeing Xu Wei's full of interest, the instructor was in high spirits and said excitedly: "YoucanBreathFreshAirThere, AWSOME!" As he spoke, he tightened the coat on his body, Xu Wei noticed this detail, and the whole person felt bad, he had a feeling that the instructor had premeditated, at first he wondered why the weather was not cold, and the instructor still had to wear a coat, but now he knows, insidious capitalism!

As Xu Wei had guessed, the plane crossed 8,000 feet and marched towards 10,000 feet. When crossing 8,000 feet, Xu Wei had to warm himself through his arms, and the instructor smiled, but he was kind enough to close the vents, so that no cold air would come in, and it would be warmer.

When the plane reached 10,000 feet, the instructor turned his head and said, "weare20milestoathensbut10,000fthighsoweneeddescendveryveryfast." After saying that, the direct throttle received the bottom, the 40-degree slope turned down, and the emergency descent was made!

The altimeter dropped rapidly, but the speed did not increase, which was the essence of the emergency descent, but soon Xu Wei noticed a big problem: his eardrums began to ache. The rapid drop results in inconsistent air pressure inside and outside the ear, resulting in tingling of the eardrum.

“**！” Xu Wei really couldn't stand the fact that his ears were like he had just taken a bath and had entered the water, his voice was extremely unreal, and the tingling sensation became more and more obvious, he kept swallowing saliva, and the theory class said that this could relieve the symptoms, but Xu Wei's saliva was almost dry, and the pain did not decrease in the slightest.

"Aviation medicine is all about dogs." Xu Wei scolded secretly.
