Questions about the B 747, the default flight simulator

There are several problems that arise in the middle of what you said.

In reality, if you are flying on a 747, the actual speed you see on the TV screen in the cabin is the kilometer system, i.e.: 1 nautical mile = kilometer hour. If there is a Boeing 744ER in reality, the maximum cruise speed of the model is Mach, Mach 1 = 1 times the speed of sound, but in FSX, the speed you see in the cockpit is all nautical miles, and the speed meters in the cockpit are calculated according to nautical miles.

1 knot (kn) = 1 nautical mile Hour = (1852 3600) m s is the unit of speed, 1 nautical mile (n mile) = 1852m is a unit of length, 1 knot is equal to 1 nautical mile per hour, that is, kilometers (kilometers) per hour, and the number of Mach numbers cannot be calculated.

Since the Mach number is the ratio of velocity to the speed of sound, and the speed of sound has different values at different altitudes, temperatures, etc., it is not possible to convert the value of to units such as km hr or mph, and the Mach number cannot be used as a unit of speed. The biggest function of the Mach number is to distinguish between subsonic speeds that are not up to times the speed of sound, penetrating speeds that are up and down the speed of sound, supersonic speeds that are times the speed of sound, and hypersonic speeds that exceed five times the speed of sound.

Doesn't that make sense?

Hehe, in response to your question, I went to the encyclopedia to look at the relevant parameters about 747, which said that the maximum cruise speed of 747 is about Mach, pay attention, the unit here is Mach, at high altitude, the cruising speed can not be used in nautical miles hours as a unit.

So how many nautical miles is Mach? The answer to this question is not certain, because the airplane is not a car, it is not on the ground, it flies in the air, Mach refers to a value relative to the speed of sound when an object moves, and the speed of sound propagation is not the same at high altitude and on the ground. If it is on the ground, then the Mach is 595 nautical miles, but at high altitude, then it is more than 300 nautical miles (the specific amount depends on how high you are), so at high altitude, the 747 cannot fly over the Mach, and after flying at this speed, the plane is going to disintegrate, which is very dangerous!

Do you agree with me? Also, what you said about more than 700 nautical miles are you seeing it from **? There shouldn't be a professional ** who makes such a low-level mistake.

Here it is necessary to involve the efficiency problem in FMC, as well as customs, the weight of the aircraft, the key is vacuum speed, ground speed, and gauge speed, which is very annoying.

The unit of speed on FSX is nautical miles.

I'm sorry I don't understand the default 747, I only understand PMDG747 (please search for FSAAC for details), according to the method of PMDG747, light up the LOC interception heading lane, reach the appropriate position The aircraft Fengyuan will automatically turn, at the same time, HDG (heading keeping) will also be disconnected at the same time, and the aircraft will automatically turn when it reaches the appropriate position, and then wait for the glide path indicator to appear when the APP (automatic approach) is lit, and the LOC (heading interception) will also be disconnected at the same time.

In addition, what are you talking about in all directions, HDG (course keeping) or LOC (course lane) trillion accompaniment? I'm sorry I only have the default 737-800 tutorial for the fsx version.

Runway magnetic heading positioning? , In the communication, he will say that the magnetic heading positioning, is not OK you can land manually, very simple, control the speed, open the flaps to the maximum on the line, don't forget to drive the car and thrust revers, if it is not easy to control, you can open the speed brake before landing.

Now I will talk about the landing points of 747.

1.Approach speed and altitude: The Boeing 747 is a four-engine jumbo jetliner, and its safe flight speed will be relatively high, requiring about 150 to 170 knots when landing.

The flaps, of course, have to be put down in their entirety. When the ILS signal is intercepted, the altitude of the aircraft is generally maintained between 1,800 and 2,500 feet. ps:

You can approach at a speed of 180 200 knots. Of course, keep in mind that when approaching the runway, it is reduced to about 150 knots.

2.Press the app: When the aircraft intercepts the ILS, there will be several dots below and to the right of the level, including reeds and an oval object moving between these points.

This is where the aircraft is shown relative to the glide path. Generally speaking, when the glide path is just intercepted, the oval object on the right will stay at the top, when the aircraft flies along the course for a period of time, the oval object on the right begins to fall slowly, when it falls to the position of the middle point or a little bit up, you can turn on the APP approach hold switch, then the altitude hold will be automatically turned off, the aircraft begins to fall, and the time speed close to the runway can be maintained at 150 170.

3. Cut off the autopilot. When there are still 200 500 feet above the ground, you can disconnect the automatic throttle and autopilot, which is limited to the default aircraft, because some plug-in aircraft have errors in the navigation data, will fly lower or higher, easy to land early or delayed, then you need to disconnect the autopilot earlier. Please pay attention to the 4 lights on the runway at any time, when the aircraft is in the glide path, the color of the lights is two white and two red, if it is high, it is more white, and if it is low, there are more red lights, if the color of the lights is not normal, please disconnect the automatic driving back to the safe height in time to land manually!

Talk about the belt. Happy flying! Thank you!

Pure hand play, real flying experience! Old hand!

After entering the entry frequency, cut into the glide path (I forgot that the height is too high). There will be two red dots on the dashboard on the left, press the app when one of the red dots reaches the highest point (I remember there is a prompt sound). When you open the app, the altitude hold and speed hold will be automatically cut off.

The default machine of FSX does not have an automatic landing function, so my personal habit is to turn off the automatic driving main switch when it is 500 meters above the ground.

I'm also a newbie, and I hit it myself, hope!

FMC (travel computer) shows a maximum speed of 167 knots, generally 150 155, pull up the steering stick when landing, the rear wheels land first, turn on the reverse spray when the landing gear lands, open the spoiler, by the way, don't forget to put the flaps when landing, the lights next to the airport runway must be red and yellow, and the speed can be reduced to 10 knots to turn into the tarmac (don't forget to turn off the engine), me.

Pick me! Huh

140-160 knots, but the fuel cannot be more than 50 tons, otherwise it will definitely be overweight.

ls, pick you a fart, you can't say the noun.

150 is best Pull the wing airflow control panel to the maximum, release the throttle, and dive slightly to 1000m up and slowly pull the lever.

Better control if there is a handle! Pick me.

And why look at the route. FLM doesn't need to go directly to the ILS to open navigation and watch the avionics association. (If you don't even need radio navigation, you won't be qualified to fly the B747.) Practice the small plane and come back. Flying does not need to rely on routes.

And a few clicks on the switch under that main display. Chances are you, he's hiding.

Obviously, when you land, the elevation angle is too large, and half of me enters the field manually, so I use the elevator to maintain an elevation angle of 1-5°, and when the rear wheel is about to hit the ground, the net is pulled. Be sure to ground the rear wheel first, I have not seen the front wheel grounded without crashing in the 4 years I have flown so far.

When the B747 approaches, disconnect the autothrottle and autopilot at the decision height, maintain a 3-degree elevation angle, ground the front and rear wheels to land first, or you can install an automatic landing system on your B747.

Finally, when you are 200ft above the ground, disconnect the automatic driving, use the joystick or keyboard to control the throttle and attitude, and it is OK, and the automatic driving is not credible.

Isn't it okay to give it a try, if your current speed is too big, then add 10 knots and see, if it doesn't work, continue to add until 3-5 degrees is not the right approaching speed. The default machine is not fine, there is no FMC, the fuel volume and load are not known, and the specific approach speed is not easy to calculate. Probably..

If you are full of oil, try 165 knots.

Method 1:

When you enter the plane, turn on the power first, turn all the switches off, and then turn off the power.

Method 2: PMDG] comes with a cold cabin profile, which can be obtained in the flightplan.

Open the pmdg menu, open the cold storage file, and the aircraft will be in the cold storage state!
