What does the airplane fly in the sky rely on to point the way

Radar, now there is a GPS electronic map navigation system, you can see the status of your aircraft on the electronic map, the direction of the nose, the flight to, and other information, which is very intuitive. Traditionally, you can also rely on observing the sun's position to determine the direction.

How does an airplane fly in the vast sky and there is no reference in the air, how do you discern the direction?

As follows:

1. Huge planes rush into the blue sky.

2. The aircraft of the exercise rushed into the clear sky.

3. The white plane rushed into the cloudless sky.

4. The plane that takes off into the sky rushes into the vast sky.

5. The silver plane rushes into the boundless sky.

Supplemental Sentence Method:

1. According to the context, reasonably deduce the content of the supplement. When supplementing, it is necessary to consider the unity of the object and topic of the statement, and the reasonableness of the sentence structure.

2. Pay attention to the genre of narration, different styles often have different contexts, and corresponding reading thinking should be adopted.

3. Clarify the level of expression and the logical order of expression - the relationship between the total score, the relationship between the point of view and the material, the relationship between the phenomenon and the essence, the juxtaposition relationship, the turning relationship, the causal relationship, the conditional relationship, the echo relationship, etc., and pay special attention to the related words.

4. Between paragraphs and sentences, it is possible to follow the development process of things, or according to the relationship between time, cause and effect, conditions, etc.

5. If the supplement is a sentence, see clearly whether it is the general opening sentence of the general leader, the transition sentence connecting the previous and the next, the summary sentence at the end, or the declarative sentence of the supplementary example, the comparison sentence that is laid out and rendered, and the rhetorical question that is asked knowingly.

A brief introduction to the phases of aircraft flight.

In order to complete a flight mission, the aircraft must go through several stages: taxi, take-off, climbing, cruising, descending, and landing. 1. Taxiing and take-off phases.

The aircraft completes all ground services before the flight. Including the completion of passenger boarding, the completion of cargo and baggage loading and unloading, the completion of inspection by the maintenance personnel and the signing of documents to release the aircraft, the acquisition of relevant flight information by the crew from the air traffic control department, the joint verification of personnel by the ground business check-in personnel and the crew, and the correct loading list of the aircraft;

Then, after applying to the air traffic control department and the control tower and getting permission, start the engine on the apron, and arrive at the runway end through the taxiway to prepare for takeoff. It is the taxiing stage, in this stage the aircraft is like a moving vehicle, to operate in accordance with the traffic requirements on the ground, the taxiing section is the time when the aircraft is the heaviest weight, and it is also the time when the pilot makes various preparations and inspections before takeoff, and the same as flying in the air, it also needs to be careful and careful.

2. Climbing stage.

There are two ways, one is to continue to climb at a fixed angle to reach a predetermined height. This has the advantage of saving time, but the power required for the engine is high and the fuel consumption is high. The other is a stepped climb, after the aircraft rises to a certain height in Naziye, it flies horizontally to increase speed, and then climbs to the second altitude, and climbs to a predetermined altitude after several stages, because the lift of the aircraft increases with the increase in speed, and the fuel consumption at the same time makes the weight of the aircraft continue to reduce, so this climb is the most fuel-efficient.

3. Cruising phase.

After the aircraft reaches a predetermined altitude, it maintains a horizontal constant velocity flight state, at which time if there is no influence of weather changes, the pilot can follow the selected route to fly stably at a certain speed and attitude, the aircraft almost does not need to be maneuvered, and the pilot generally only needs to carry out the necessary monitoring. This phase has the lowest flight accident rate.

1. Visual navigation: mainly rely on ground signs and maps to determine the route.

2. Speculative navigation: The pilot uses two tools, the clock and the slide rule, to calculate the relationship between the speed, distance and angle of the aircraft when it flies, so as to determine whether the aircraft flies on the selected route.

3. Magnetic compass: The reading obtained by the pilot when using the compass on the aircraft is added to the compass to get the magnetic direction, and then the magnetic difference is added to get the true direction. The route is determined by the magnetic difference of each place marked on the air map of the year.

4. Radio talk: The pilot contacts the ground personnel through radio talk to determine whether the route is correct.

Summary. Hello! We'll be happy to answer for you.

The airplane moves relative to the air, and the direction of its motion is.

Hello! I'll be glad to answer your questions, please wait, I'll answer your questions thoroughly.

Good to you! Glad to answer for you :1

The direction of the airplane's motion relative to the air is parallel to the flight speed, which is opposite to the flight speed of 2As the aircraft moves forward, the wings move relative to the surrounding air, passing head-on with respect to the air current. I'm glad to answer for you and have a great day.

Summary. According to the purpose of the aircraft, there are civil aviation aircraft and national aviation aircraft. National aviation aircraft refers to the aircraft used by the military, police and customs, civil aviation aircraft mainly refers to civil aircraft and helicopters, and civil aircraft refers to civil passenger aircraft, cargo aircraft and passenger and cargo aircraft.

According to the type of aircraft engine, there are propeller aircraft and jet aircraft. Propeller history aircraft, including piston propeller aircraft and turboprop aircraft, aircraft engines are piston propeller type, which is the most primitive form of power. It uses the rotation of the propeller to push the air towards the rear of the aircraft, and uses its reaction force to propel the aircraft forward.

The higher the propeller speed, the faster the flight speed. Jets, including Vortex Jets and Vortex Fan Jets. The advantages of this type of model are simple structure and fast speed, generally up to 500-600 miles per hour; The fuel cost is economical, the loading capacity is large, and it can generally carry 400-500 people or 100 tons of cargo.

According to the number of engines of the aircraft, there are single (motorized) aircraft, twin-engine (motorized) aircraft, three-engine (motorized) aircraft, and four-engine (motorized) aircraft.

According to the flight speed, there are subsonic aircraft and supersonic aircraft, and subsonic aircraft are divided into low-speed aircraft (flight speed less than 400 kilometers per hour) and high subsonic aircraft (flight speed Mach number. Most jets are high subsonic aircraft.

According to the range of the aircraft, there are short-range, medium-range and long-range aircraft. The long-range aircraft has a range of about 1,100 kilometers and can complete intercontinental cross-sample flights without landing. Medium-range aircraft have a range of about 3,000 km, and short-haul aircraft generally have a range of less than 1,000 km.

Short-range aircraft are generally used for regional routes, so they are also called regional aircraft. Medium and long-range aircraft are generally used for domestic trunk lines and international routes, also known as trunk aircraft.
