The Treasure Hunt of an Antique Dealer

New York should be the world’s most prosperous and modern super metropolis. However, to the surprise of many people, there are still many wild animals living here. In Central Park alone, more than 280 species of wild birds can appear throughout the year. This figure is even greater in New York.

The reinforced concrete high-rise buildings in the bustling Manhattan are home to wild birds, not to mention the Long Island area with a good natural ecological environment. There are many bird nests in Zhang Nan’s own manor, many in the woods, and even on the exterior walls of the houses. The first type of gaps and cavities have also become good places for birds to build nests.

As long as they don’t block their chimneys and their nests block the roof drainage system, the staff in the manor will not destroy the homes built by the birds, because the boss and the proprietresses think that the birds can be heard in the early morning. Waking up in the sound is a great thing.

But it's a cold winter, and the larger migratory birds have gone to the southern Caribbean to spend the winter, and there are very few large groups of resident birds, so Zhang Nan complained when he heard that the plane was hit by a group of birds.

If it's just a small bird, such as a house sparrow, unless a swarm of dozens of them **** into the engine, otherwise the Boeing 767 cannot double-engine stop.

And small birds like sparrows can't fly high. The plane that took off at Kennedy Airport will definitely not fly far after it has double-engined and stopped at that altitude.

Birds are extremely harmful to the take-off and landing of aircraft. Every year, some aircraft are hit by birds. Therefore, general airports are equipped with bird repellent equipment, but this cannot completely avoid accidental bird strikes.

The 767 took off from Kennedy International Airport. The route should be to enter the Atlantic Ocean in the southeast, and then fly around Long Island towards Europe. Otherwise, it should go to Newark International Airport on the west side of the city or Tetbury on the northwest side. Le airport made an emergency landing.

In the take-off phase, the double-engine parking will not turn back to the take-off airport: once a 360-degree turn, the probability of a stall and crash is too high. In that case, it is safest to only adjust the heading at a small angle.

I don’t know if it’s bad luck or good luck. Since it can glide to Zhang Nan’s "Alice Greene Airport" 33 kilometers east of the Könide Airport, it makes an emergency landing, which means that it’s flying altitude is very likely when it was hit by a bird. There is already more than one kilometer, and the take-off course is also more appropriate.

If it is the moment when it takes off in the direction of the Atlantic, it is hit by a collision and the twin engines are stopped, then either a crash or a forced landing at sea is its only ending!

Staying away from the tarmac, I am worried that the plane will accidentally land on my head. I hope that the plane has begun to discharge oil at sea. Otherwise, the 767 flying over the Atlantic Ocean is almost full of fuel, and the maximum allowable landing weight is less than the maximum take-off weight. of.

The gadget crashed and exploded. If these sixty or seventy tons of fuel are on, it’s not a joke!

Running far to watch the excitement, only then did I realize that the passenger plane that had crash-landed on the Hudson River more than ten years later was hit by a group of big birds in the winter, because it was said in the relevant documentaries and movies that I had seen. The river is very cold. Fortunately, the plane floats on the water after a forced landing, otherwise it will freeze to death!

The river is cold, needless to say, it is definitely winter.

The plane also seemed to be hit at a relatively high flying altitude. It would have appeared in the southwestern air that the 767 was hit by birds in a relatively high airspace when it climbed to the naked eye. It didn't seem to be too unbelievable.

When the plane approaches the airport, as long as the speed and altitude are sufficient, it can basically land safely.

Not to mention the 767, Zhang Nan’s airport didn’t even have a problem with the 747.

"Alice Greene" Airport has two intersecting runways. The second runway running north-south is 2000 meters long. The main runway from northwest to southeast was lengthened, reinforced and expanded last year, reaching a length of 3,200 meters, which can fully satisfy Boeing. The 747 takes off and landed with full load.

The Boeing 747 freighter needs to roll about 2,800 meters on the runway when fully loaded, and it needs to roll more than 1,800 meters when landing with a full load, which is 1 km shorter than the take-off distance. Any other civilian aircraft that does not exceed this distance, even if you add a military aircraft, That is only Maozi's An 225 full-load takeoff required to exceed this distance.

The full-load takeoff roll distance of the An 225 is 3,500 meters, but please note: this "rolling distance" is not the distance from the ground, but includes the distance required for the aircraft to climb to a height of 35 meters. This data requirement of the Boeing 747-400 It's 3,018 meters, and one or two hundred meters farther for the cargo plane.

The main runway of Zhang Nan’s private airport can barely meet the full-load take-off conditions of the An 225, because there is a 125-meter "safety reminder section" at both ends of the main runway, which allows the actual length of the entire runway to reach The distance is 3450 meters, and the full-load distance of the An 225 is more than 3000 meters.

And to the southeast of the main runway is a cemetery with an oblique angle of more than 800 meters and a flat terrain, and to the southeast is a single private residential area with only two or three floors~www.readwn.com~ enough An 225 has a sufficiently good headroom after takeoff with a full load.

Of course, everything goes together, because Zhang Nan has already bought the world’s only super transport plane named "Dream", but it is busy transporting the Soviet Union to Africa with a group of younger brothers An 124 and An 22. Those leftover supplies in the warehouse.

Even if it waits until it is empty, unless there is a transportation business for super-sized cargo, the An 225 will not come to the United States, and there is no need to let the super giant come to its own airport to show off.

Its own airport's take-off and landing conditions rank first among all private airports in the world. The lengthening of the main runway can cost a lot of money, and the cost of land acquisition can hardly be borne by the rich.

This time the 767 that hit the bird swarm had to make an emergency landing at its own airport, because all private airports in the United States have an obligation that needs to be fulfilled, that is, once an aircraft emerges in an emergency, you have to unconditionally open the airport for those aircraft.

It’s a great rule, and it’s probably the rule in the world.

Zhang Nan is already six to seven hundred meters away from the runway where he will stand and watch the lively place. Even if the guy in the sky falls down, he can’t hit him, but even so, watching the plane gliding and making an emergency landing is still pretty good. Stimulating.

However, just five or six seconds after spotting the 767 in the air, Zhang Nan discovered that it was facing the 2000-meter-long Runway 2. It should have turned a 90-degree turn from the south, so that the turning angle is the smallest and the loss is the smallest. The speed and height are also the smallest.

The 2000-meter runway is sufficient for landing the Boeing 767.

But just a few seconds later, someone next to Zhang Nan shouted: "No! It's too low, something might happen!"
