Joining Sichuan Airlines starts with rescuing the captain of a powerful country

Chapter 191 Landing in heavy fog, relying not on technology and experience anymore, but on high technology
What is RNP (AR) flight technology?
To put it simply, RNP (AR) flight technology is actually a brand-new navigation technology.

The full name is Required Navigation Performance.

Due to the high accuracy of this technology, it can assist pilots in taking off and landing in various bad weather conditions, especially at airports with low visibility.

The function of RNP (AR) flight technology is similar to VOR navigation or ILS navigation, which provides navigation for aircraft (mainly passenger and cargo aircraft).

But RNP(AR) is more like an upgraded version of VOR and ILS.

The traditional navigation (VOR and ILS systems) of passenger and cargo aircraft relies heavily on ground guidance. Without ground guidance, the aircraft will be like a headless fly and cannot tell the difference between east, west and north.

But RNP(AR) relies on the precise navigation provided by the satellite positioning system.

Pilots can identify directions and position accurately without relying too much on ground navigation facilities.

This allows the aircraft to land safely and accurately even in bad weather and poor visibility conditions, reducing return due to weather conditions and greatly improving flight safety.

RNP(AR) flight technology is able to use satellite positioning systems because the program uses internal systems rather than external beam flights.

Some people may find it strange.

Since RNP (AR) flight technology is so easy to use, why are the current mainstream navigation systems for passenger and cargo aircraft still VOR and ILS systems?
That's because RNP(AR) flight technology still has big flaws.

If the aircraft needs to use RNP (AR) flight technology navigation, it needs to enter the parameter values ​​correctly before arriving in the approach airspace, so that accurate guidance can be achieved.

If parameter values ​​are entered incorrectly, it can be disastrous for the aircraft.

Moreover, RNP (AR) flight technology cannot achieve full navigation and can only switch the navigation mode before reaching the approach airspace.

The relationship between RNP (AR) and traditional navigation systems such as VOR and ILS is like Liang Ge’s dimension guiding the aircraft.

The former is horizontal guidance, while the latter two are vertical guidance.

In fact.

It is most foolproof if an aircraft is equipped with the above two navigation systems at the same time.

But because most airports in the world don't often encounter bad weather, visibility won't be reduced on a regular basis.

Therefore, installing two navigation systems at the same time will not only increase the cost, but the more systems there are, the greater the probability of system downtime.

Just to be on the safe side.

The two major aircraft manufacturers, Boeing and Airbus, will only modify their aircraft when customers require the installation of both navigation systems.

This is the same as the aircraft flying on the "high plateau" route, which are also specially modified.

Nyingchi Milin Airport is particularly special.

The airport is nearly 3000 meters above sea level and is considered a 'high plateau' airport.

And because of the year-round thick fog and low visibility, it is the only airport in the country where all aircraft takeoffs and landings must implement RNP (AR) flight technology.

Capital time, 11:05.

Sichuan Airlines flight 3u5587 is less than 100 kilometers away from the destination of this trip.

Lu Qingzhou sat in the captain's seat.

Hold the throttle lever with one hand and the control lever with the other.

I saw him gently pulling the operating lever while reducing the fuel supply.

The plane's nose turned slightly downward, then roared toward the valley below.

In the passenger seat.

The second captain, Liang Dong, kept talking to the Rongcheng district police officer. While receiving the instructions from the Rongcheng district police officer, he repeatedly conveyed the instructions to Lu Qingzhou.

Just like a repeater without emotions.

at this time.

The aircraft's driving mode has been switched from automatic mode to manual driving mode.

Before the plane dived downward, Lu Qingzhou entered parameter values ​​into the RNP (AR) system based on ground and satellite data.

A few minutes later.

The altitude of the plane has dropped from 10000 meters to 5000 meters. at this time.

The plane fell from the sky until it entered a wide canyon before Lu Qingzhou pulled up the nose of the plane and changed to a level flight attitude.

"Bingbing, look out the window." Xu Yichen, who was sitting in the second captain's seat, pointed to the porthole and whispered to Chen Bingbing, "That's Namjagbarwa Peak over there. Let me tell you, don't look at the air tickets for this route. It’s expensive, but the beautiful scenery during takeoff and landing is worth the price. ”

Chen Bingbing quickly turned to look out the window.

really.

Just to the left of the plane.

A majestic snow mountain stands on the ground.

The snow-capped mountains are majestic and the scenery on both sides of the valley is also very pleasant.

The plane flying in the valley is like being in a fairyland.

Chen Bingbing couldn't help but exclaimed, "It's so beautiful. I finally understand why so many people yearn for the snowy plateau so much. Being able to enjoy these beautiful scenery makes it worth dying here."

Inside the cabin.

Almost all the passengers came to the window at this time.

When the snow-capped mountains passed by their eyes, everyone let out a "tsk-tsk" sound of exclamation.

Because all passenger planes flying to Linzhi Milin Airport have turned on RNP (AR) flight technology, the planes can fly safely in relatively low airspace.

The flight altitude is low, almost passing by the snow-capped mountains such as Namjagbarwa Peak.

Therefore, passengers on the plane can enjoy the snow-capped mountains and the beautiful scenery along the way up close.

Especially when the sun shines on the top of the snow-capped mountains, it is like covering the snow-capped mountains with a golden shawl.

Another kind of holy beauty.

The plane flew at such a low altitude that it almost flew close to the lake in the valley.

However, Lu Qingzhou and Liang Dong, who were flying the plane, were not in the mood to enjoy the beautiful scenery.

Because right in front of the plane, a thick fog looked like a giant beast with its mouth wide open, just waiting for the plane to "fall into the trap".

Boom boom. Boom boom.
Others on the plane haven’t had enough of the beautiful scenery along the way.

Flight 3u5578 plunged into thick fog.

Everyone's sight was blocked instantly, as if they had stepped from heaven to hell.

Such a magical experience.

It will be unforgettable in the future.

Huba Huba
The wipers on the airplane windshield were working diligently, constantly sweeping the water droplets attached to the windshield to both sides.

But no matter how hard the wipers work, they can't wipe away all the thick fog blocking the road ahead.

Lu Qingzhou and Liang Dong both stared wide-eyed, but they still couldn't see clearly where the road ahead was in the thick fog.

Even when driving, visibility less than 100 meters is dangerous.

Not to mention flying a plane.

This cannot be compensated by superb technology and rich experience.

Therefore, both of them now place all their hopes on RNP (AR) flight technology.

I hope this system, which relies on satellite navigation, can function stably as always.

otherwise.

Everyone on the plane had to Barbie Q together.
