What is the highest possible flight level?

A: The highest commercial airliner ceilings

ceilings

With respect to aircraft performance, a ceiling is the maximum density altitude an aircraft can reach under a set of conditions, as determined by its flight envelope.

Ceiling (aeronautics) - Wikipedia

are 45,000 feet. It is not uncommon to fly at the certified ceiling of the airplane.

What are the highest flight levels?

Most commercial aircraft are approved to fly at a maximum of around 42,000 feet. This maximum is also known as a 'service ceiling. ' For example, for the double-decker Airbus A380 'superjumbo' quadjet, this ceiling is 43,000 feet. Meanwhile, for the Boeing 787-8 and -9 'Dreamliner,' it is 43,100 feet.

What happens above Flight Level 410?

At FL 410 and above, 4,000 ft intervals are resumed to separate same-direction aircraft and only odd Flight Levels are assigned, depending on the direction of flight: Track 000 to 179° – odd flight levels (FL 410, 450, 490, etc.) Track 180 to 359° – odd flight levels (FL 430, 470, 510, etc.)

What is flight level 600?

Class A airspace is generally the airspace from 18,000 feet mean sea level (MSL) up to and including flight level (FL) 600, including the airspace overlying the waters within 12 nautical miles (NM) of the coast of the 48 contiguous states and Alaska.

Why is there no FL420?

Above FL410, RVSM does not apply, and vertical separation reverts to a minimum of 2000 feet with only odd-numbered flight levels. Thus, FL420 is not a valid cruising level anywhere globally, and you cannot plan to fly at that altitude.

Why is Flight Level 180 so Special? Why can it be Unusable at Times?

Can a plane fly over Mount Everest?

Tim Morgan, a commercial pilot writing for Quora says aircraft can fly above 40,000 feet, and hence it is possible to fly over Mount Everest which stands at 29,031.69 feet. However, typical flight routes do not travel above Mount Everest as the mountains create unforgiving weather.

Can a plane fly at 60000 feet?

Question: What is the highest altitude an airplane can fly? Answer: The highest commercial airliner altitude was 60,000 feet by Concorde. The highest military air-breathing engine airplane was the SR-71 — about 90,000 feet.

What happens if a plane flies too high?

Aerodynamic altitude: If a commercial airliner flies too high, it will encounter less dense air passing over the wings to create lift. This can cause the plane to stall and fall out of control. Depending on the weather conditions and aircraft weight, this can occur anywhere between 40,000 and 45,000 feet.

Can planes stop in air?

Airplanes stay in the air because of one simple fact-- there is no net force on them. And with no net force, an object at rest stays at rest and an object in motion stays that way, even if it's in midair 10 kilometers above the Earth's surface.

How high can a plane fly without oxygen?

For Part 91 General Aviation operations the required flight crew must use supplemental oxygen for any portion of the flight that exceeds 30 minutes above a cabin pressure altitude of 12,500 feet mean sea level (MSL) up to and including 14,000 feet (MSL).

Why don t we fly west to Japan?

The primary reason airplanes don't fly over the Pacific Ocean is because curved routes are shorter than straight routes. Flat maps are somewhat confusing because the Earth itself isn't flat. Rather, it's spherical. As a result, straight routes don't offer the shortest distance between two locations.

Why do planes not fly over Antarctica?

There are very few cases of airplanes flying over Antarctica. The rough weather conditions and low visibility make it extremely difficult to fly and land a plane over the continent.

Is it safe to fly over the ocean?

However, because of lessons learned from its history and the improvements in aircraft and engine reliability, crossing the oceans is deemed as safe as flying over land. With the rules of ETOPS flying in place, the crew of an aircraft will always know where the nearest diversion airfield is.

Why are there no more Trijets?

As engines were also getting bigger and more efficient all the time, airlines could now operate with two engines on routes previously inaccessible to twinjets. Cost efficiency always wins in aviation, and so, the trijet started becoming obsolete.

At what altitude do flight levels start?

Flight Level (FL)

Only above the transition level (which depends on the local QNH but is typically 4000 feet above sea level) are flight levels used to indicate altitude; below the transition level feet are used.

What is the highest VFR altitude?

Maximum altitude or flight level

VFR civil flights shall not fly above FL200.

Is it illegal to fly over Disneyland?

The sky over Disneyland in Anaheim and Walt Disney World in Orlando is "national defense airspace." Intentionally violating Mickey and Minnie's airspace, the alerts warn, could result in interception, interrogation and federal prosecution.

Is it illegal to go to Antarctica?

Travelers do not need permission to go to Antarctica, but tourism operators must hold a valid permit. First, a bit of background on why it is legal to visit Antarctica. Antarctica is not a country. The continent is protected by the Antarctic Treaty, which preserves it for peaceful and scientific use.

Why can't we go to the North Pole?

Since the North Pole sits on drifting ice, it's difficult and expensive for scientists and explorers to study. There isn't land or a place for permanent facilities, making it difficult to set up equipment.

What is the longest flight in the world?

Undefeated record: The world record for the world's longest continuous flight was set in 1959 by Robert Timm (pictured) and his co-pilot John Cook. Months in the air: The men flew in this four-seater aircraft for 64 days, 22 hours and 19 minutes.

Why do planes not fly straight across the Atlantic?

A: The tracks across the Atlantic are determined daily to take into account the meteorological conditions of the moment. If there are strong winds, the eastbound tracks will be farther north to take advantage of them, while the westbound flights will be routed south to avoid the headwinds.

Why do planes take off so steeply?

The idea is to get as much altitude as possible, as close to the airport as possible. So you have a relatively steep initial climb, followed by a reduction of climb angle to cruise climb and a power reduction.

How cold is it at 30000 feet?

A: The standard temperature for 30,000 feet is -44.5C or -48F (Source: meteorologytraining.tpub.com/14269/css/14269_75.htm). All materials used in airplanes are designed and tested to withstand temperature extremes.

How cold can planes not fly?

But, is there an exact temperature that makes it too cold for a commercial airplane to fly? “There is not a specific temperature,” says Tom Haines, Senior Vice President of Media, Communications & Outreach at the Aircraft Owners and Pilots Association (AOPA).
