Answer: The flight operator files a requested altitude, usually done by the flight dispatcher, based on performance and economics. Air traffic control reviews the flight plan, checking for conflicts. They issue the cruising altitude based on the requested flight plan and other traffic.
How do pilots know the altitude?
Absolute altitude refers to the actual distance the aircraft is flying in relation to the ground and is expressed in “feet above ground level.” This type of altitude is generally determined using a radar altimeter, which measures how long it takes radar signals to reach the ground and reflect up to the plane.
How do pilots know which way to fly?
Then the plane passes over a middle marker and an inner marker, radio reference points that tell the pilots exactly where they are along the approach path. Once the pilot is at the inner marker, he or she looks up from the instrument panel and hopes the runway lights are right there.
How is altitude determined?
Altitude is related to air pressure. In fact, aviators and mountaineers can measure their altitude by measuring the air pressure around them. This is called indicated altitude, and is measured by an instrument called an altimeter. … High-altitude locations are usually much colder than areas closer to sea level.
What determines cruising altitude plane?
According to Thrillist, a plane’s altitude is determined by its current weight and the atmospheric conditions at the time of flight. A flights direction (as mentioned above), the amount of turbulence (based on reports by other pilots in the air), and flight duration are also factors.
How do pilots know when to descend?
Answer: Pilots plan the descent based on the wind and air traffic flow. … In addition to the radar guidance from air traffic control, pilots program navigation computers and radios to ensure proper lateral and vertical paths.
What are the four forces of flight?
It flies because of four forces. These same four forces help an airplane fly. The four forces are lift, thrust, drag, and weight. As a Frisbee flies through the air, lift holds it up.
Why do planes have 2 pilots?
The primary reason for having two pilots on every flight is safety. Obviously, if something happens to the captain, a plane must have another pilot who can step in. Additionally, the first officer provides a second opinion on piloting decisions, keeping pilot error to a minimum.
Is learning to fly difficult?
With that said, while flying isn’t a difficult skill to learn, you must be willing to take your flight training seriously so you can pass your knowledge exams check-rides to become an FAA-certified pilot! … You will learn your basic knowledge of becoming a pilot in Ground School. Learning to fly is easier than you think.
Can you see other planes while flying?
In many cases airliners fly the same paths through the sky. You might well see them if you were in the cockpit and looking to the front but as a passenger you only can look out the side of the plane. … Airplanes are diffiuclt to see from a distance.
What are the 5 types of altitude?
The 5 Types Of Altitude, Explained
- 1) Indicated Altitude. Let’s start with the easiest – indicated altitude is simply the altitude you read directly off your altimeter. …
- 2) Pressure Altitude. When you set your altimeter to 29.92, you’re flying at standard pressure altitude. …
- 3) Density Altitude. …
- 4) True Altitude. …
- 5) Absolute Altitude.

What is the best altitude to live?
For most people, a moderate altitude of 8,000 feet is safe, but many have temporary symptoms, and a few develop serious problems. Above 8,000 feet, the risks rise. Still, healthy men in search of a challenge can ascend higher, but to avoid problems they should take special precautions.
Does altitude affect blood pressure?
The higher you travel, the less oxygen you take in with each breath. The body responds by increasing the heart rate and the amount of blood pumped with each beat. This temporarily increases blood pressure until the body adapts to the lower oxygen level, usually within a couple of days.
What is the average altitude of a flight?
Commercial aircraft typically fly between 31,000 and 38,000 feet — about 5.9 to 7.2 miles — high and usually reach their cruising altitudes in the first 10 minutes of a flight, according to Beckman. Planes can fly much higher than this altitude, but that can present safety issues.
What is the temperature at 35000 feet?
At 35,000 feet the air temperature is about -54C.
Why planes do not fly over Tibet?
According Debapriyo, most commercial airlines avoid flying directly over the Himalayas. This is because “the Himalayas have mountains higher than 20,000 feet, including Mt Everest standing at 29,035 feet. However, most commercial airplanes can fly at 30,000 feet.”
