What is the black block in front of the cockpit of some airplanes?

The definition of the term "black block" in the question is a bit vague, so let's look at two aspects.

There are only two angles to look at the cockpit of an aircraft, the cockpit from the external nose and the cockpit from the interior cabin.

Let's start with the cockpit from the external nose, as shown below

Looking at the cockpit from the outside, only a few windshields can be seen. The most important thing is that due to the influence of angle and lighting, the windshield seen is not all transparent or blue, and many cases will see black glass, such as the picture below:

At this point, the windshield is like a "black block".

But it shouldn't be many cases to describe the windshield as a black block, because people with a little common sense know that this is glass, so let's look at the cockpit from another angle. As shown below:

Looking at the cockpit from this angle, two windshields, two seats, some buttons and handles, and most importantly, can be seenSix "black blocks". These six black blocks are actually the plane's liquid crystal display.

Since it usually has a black background, it is black when viewed from a distance. Actually, it's not all black, as shown below:

The display in the image is not completely black, and there are different colors for different contents.

In this picture, the light outside is relatively dark (this picture was taken at night and has been processed), so the brightness of the display is reflected, not completely black, or even brighter.

The emergence of the display is completely the result of the progress of aviation science and technology, through continuous development, now it is possible to do all kinds of information that the pilot needs, through several displays to display, not only improve the display efficiency, but also reduce the burden of the pilot, and it seems very sci-fi. But it's not exactly black.

The black block of the outer end part of the cockpit is the non-metallic fairing of the aircraft Doppler radar, terrain scanning radar, cloud scanning radar and combat effectiveness fire control radar, in order to facilitate maintenance and repair, and because of the different materials, there is a difference from the fuselage coating, and some are directly coated as a whole, but they are generally the fairing of the radar. The plane is white in the high altitude sunlight is more intense, the front black block is also to reduce reflection, to avoid disturbing the pilot's eyes, and with black as the background color can be earlier to see the front vision, birds, landing, etc.

Wrapping around the entire window rim, in addition to the anti-reflective effect, there is also a decorative effect, which can make the aircraft look more energetic like eyeshadow.

It is reflective paint, which is a piece of skin painted with black paint, to prevent sunlight from reflecting on the skin and interfering with the pilot's line of sight

There is nothing special, it is a piece of skin painted with black paint, which prevents the sunlight from reflecting on the skin and interfering with the pilot's vision

Only old planes have it, and that's reflective paint. Prevent the impact of sunlight on the pilot and drive safely.

The black under the cockpit of the aircraft is a circle of reflective paint, in order to prevent the light color of the aircraft or the reflection of the metal shell from affecting the pilot's line of sight.

That's part of the radome, but it's just a different color.

That's a heads-up display, on which a portion of the data necessary for flight is displayed without affecting the field of view.

Eggshells in the wind, you're fooling around again, who told you that the radar display is a heads-up display? In terms of the current one-level, three-down layout, the radar and mission maps and operations are all on the lower left display, and the heads-up display only shows the frontal range and main target. The main information of the heads-up display is altitude, speed, attitude, AOA, G-value and various auxiliary information. Look at the picture:

Is that piece of dark glass that can be moved? It is used to block the sun, because the cockpit needs to observe the surrounding situation, not just listen to the command of the tower. Prevent clear sky bumps or unexpected weather conditions or bird strikes...

If you're talking about the colorless, transparent glass that can be opened, it's the window. It is not for ventilation, it is used as an escape exit in case of emergency evacuation, and an evacuation rope will be equipped by the window.

The Flying Ginseng System Recorder, the black box that is used as a "witness" to the flight status of the aircraft, is not actually black, but often orange-red. Because it can help decipher the secrets of flight accidents, especially the flight status of the plane at the moment of the crash and some time before the crash, it is called the "black box".

Record some things When the plane has an accident, you can learn some things according to the black box.

That is"Flying ginseng system recorder"

The "black box" is one of the electronic recording devices dedicated to aircraft, and its real name is Aviation Flight Recorder. It is equipped with flight data recorders and cabin sound recorders, and all mechanical parts and electronic instruments of the aircraft are connected to them by sensors, just like the nerves in various parts of the human body communicate with the brain. It can record the relevant technical parameters and the sound in the cockpit half an hour before the plane stops working or crashes, and re-releases the recorded parameters when necessary for flight experiments and accident analysis.

The black box has strong resistance to fire, pressure, shock and vibration, seawater (or kerosene) immersion, magnetic interference, etc., even if the aircraft has been completely damaged, the recorded data in the black box can be preserved intact. All the causes of air crashes in the world are found through the black box, so it has become a witness to the accident and a "lesson from the past" to avoid the same accident and take better safety measures.

At present, most passenger planes and military aircraft are equipped with two types of black boxes.

The first is a black box called the Aircraft Data Recorder (FDR), which specializes in recording various data in flight, such as flight time, speed, altitude, skewness of the aircraft rudder surface, engine speed, temperature, etc., with a total of more than 30 kinds of data, and can record for a total of 25 hours. Before takeoff, as long as the switch of the black box is turned on, all the above data will be stored in the black box during the flight. In the event of an air crash, the flight parameters of the entire accident can be found in the black box, and people can know the cause of the plane crash.

Another type of black box called the Pilot Speech Recorder (CVR), like a tape recorder, records the voices of the pilot and the pilot, as well as the passengers, hijackers and stewardesses in the cockpit through speakers placed in the cockpit and cockpit, for 30 minutes and then restarts the recording after 30 minutes. Therefore, this black box contains important information about the plane 30 minutes before the plane crash.

Black boxes are not black, but often orange-red, mainly for the purpose of eye-catching colors and easy to find. The appearance is cuboid with a solid shell, approximately equal to.

Four or five bricks are generally large together. When a plane crashes, there is a positioning beacon on the black box, which is equivalent to a radio transmitter, and can automatically emit a specific frequency after an accident so that searchers can trace the waves. See.

It seems that the passenger put a suicide note box for the family in the event of a death. Hehe. I'm not sure either, but I think I've heard of it.

Downstairs was all wrong. This is called the trim handwheel, which controls the elevator trim tab, and reduces the pilot's fatigue by reducing the pilot's sustained lever force... And the landlord is also wrong, look at the throttle stick This is obviously a twin-engine aircraft of the Airbus series, which should be of the A320 series:

Boeing's throttle stick top crossbar is concave, while Airbus is a standard cylinder. In addition to this, Boeing aircraft do not have a black and white logo on the trim handwheel, the logo is on the shaft, whereas Airbus is marked by a black and white logo.

This is to adjust the angle of elevation of the nose of the parallel flight, adjust the angle of elevation during flight and control the angle of the nose of the aircraft to fly horizontally.

It is not clear to see, it is better to give the model number.

It looks like a landing gear retract handle.

This is obviously the cockpit of the A10A.

It seems to be the cockpit of the J-7E.

Let's look at the hatch cover first, it is a three-piece structure, and there is a support frame in the front windshield, which is a typical feature of the MiG aircraft, which is equipped with a heads-up display, but the other equipment is still electromechanical.

It's more like the J-7E

The black box records the flight data of the aircraft.

Black box - flight recorder.

The "black box" (English: black box) is one of the electronic recording equipment dedicated to aircraft. There are two black boxes, the cockpit voice recorder and the flight data recorder.

All mechanical parts and electronic instruments of the aircraft are equipped with sensors to connect to it. It can record the voice dialogue of half an hour before the aircraft stops working or crashes and the flight altitude, speed, course, climb rate, descent rate, acceleration, fuel consumption, landing gear release, Greenwich Mean Time, as well as the working conditions of the aircraft system and the working parameters of the engine.

The shell of the black box has a thick steel plate and many layers of thermal and anti-impact and compression protection materials, and is usually installed in the safest part of the tail of the aircraft. The recording medium has also been improved from a tape-based static storage recorder that can withstand greater impacts, similar to the memory chips in computers, to prevent the black box from being damaged in an air crash.
