What is FL400 flight level?

Flight Level, is the level of which altitude you are at. FL400 is 40.000FT, FL300 is 30.000FT and so on. Basically its your Altitude in feet, divided by 100.

What altitude is FL410?

RVSM reduces the vertical separation of aircraft from 2,000 feet to 1,000 feet when they're flying at altitudes from FL290 (29,000 feet) to FL410 (41,000 feet).

What altitude is FL340?

A westbound flight will cruise at even numbered flight levels—say 32,000 feet (FL320) or 34,000 feet (FL340)—again in increments of 2,000 feet.

What is FL180 altitude?

FL180 is the altitude at or above which, in North America, all aircraft altimeters should be set at 29.92, and below which they should be set to the current barometric pressure of the nearest reporting station.

What altitude is FL390?

The initial implementation is at altitudes at or above 39,000 feet Mean Sea Level (FL390) in the northwest portion of the U.S. Additional airspace, flight levels, and functionality will be added as technology and systems allow.

IFR cruising altitude (flight level) [atc for you]

What is altitude FL400?

FL400 is 40.000FT, FL300 is 30.000FT and so on. Basically its your Altitude in feet, divided by 100. FL350 - 35.000FT. FL250 - 25.000FT.

Is 4000 feet high altitude?

Mountain medicine recognizes three altitude regions which reflect the lowered amount of oxygen in the atmosphere: High altitude = 1,500–3,500 metres (4,900–11,500 ft) Very high altitude = 3,500–5,500 metres (11,500–18,000 ft) Extreme altitude = above 5,500 metres (18,000 ft)

What is the altitude of FL430?

FL430, but look at the actual altitude on the GPS screen. 44770 feet!

What is FL200 flight level?

FL200 means flight level 20,000 feet ... so I decided to larn something about flight levels. Aircraft have a device, the altimeter, to measure local air pressure. Although it doesn't measure altitude, one can calculate the altitude if you know the air pressure at ground level.

What altitude is FL300?

It means that the pilot must climb the aircraft from FL275 (27500 feet) up to FL300 (30000 feet) and then continue flying at that level.

What does FL330 mean?

In the US, any altitude above 17,999 feet above mean sea level is refered to as Flight level (FL). So FL330 would be 33,000 feet.It is impossible to have heard FL 380, it is an invalid cruising FL, you get 330, 350,370,390 and so on.... to provide 2,000 foot vertical separation!

What does FL370 mean?

A Flight Level is an aircraft's altitude at standard air pressure, 1013.25 hPa (29.92 inHg), and is expressed in hundreds of feet e.g. 37,000ft is expressed as FL370.

What altitude is fl320?

Therefore, a pressure altitude of 32,000 ft (9,800 m) is referred to as "flight level 320". Flight levels are usually designated in writing as FLxxx, where xxx is a two- or three-digit number indicating the pressure altitude in units of 100 feet (30 m).

What is flight level 410?

The answer is that FL 410 is the traditional extreme upper edge of the operating envelope for civilian jets, either airline or business jet. The very first jets were certified to 41,000 feet even though they couldn't get there unless they were virtually out of fuel or carried little payload.

Why do planes fly at 41000 feet?

The biggest reason for this altitude lies in fuel efficiency. The thin air creates less drag on the aircraft, which means the plane can use less fuel in order to maintain speed. Less wind resistance, more power, less effort, so to speak. Spending less on fuel is also great for airlines, for obvious reasons.

What planes fly at 41000 feet?

Closely related to the 747, a 737 jet has a very similar cruising altitude. The maximum cruising altitude for the new generation of 737 planes is 41,000 feet.

How high is FL600?

Above 18,000 feet (above mean sea level) the FAA considers altitudes to be “Flight Levels”. 18,000 feet to Flight Level 6-0-0 (FL600) are considered Class A airspace and represents a significant delineation between where most aerospace activities occur and the sparsely populated areas above.

What is FL100 flight level?

Very simple terms - take a flight level, multiply by 100, and that gives you the approximate altitude in feet. So FL100 is 10,000'.

What does fl190 mean?

fl-190 NOTICE OF ENTRY OF JUDGMENT (Family Law—Uniform Parentage—Custody and Support)

What is the highest breathable altitude?

An elevation of about 20,000 feet above sea level is the maximum height at which sufficient oxygen exists in the air to sustain us. By comparison, the summit of Mount Everest (the Earth's highest mountain) lies at 29,141 feet.

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 there no flight level 420?

With that said, Any aircraft above FL410 must be separated by at least 2000ft vertically so with aircraft cruising at FL410, FL420 doesn't work because that's only 1000ft above. So, above FL410 the typical even for west and odd for east altitudes don't apply.

Can you get altitude sickness at 4000 feet?

Altitude sickness typically occurs only above 2,500 metres (8,000 ft), though some are affected at lower altitudes. Risk factors include a prior episode of altitude sickness, a high degree of activity, and a rapid increase in elevation.

At what altitude does breathing become difficult?

While 8000 feet (2500 meters) is considered the usual threshold altitude for HAI, some persons are more sensitive to lower oxygen levels and may become ill at altitudes of 5000 to 7000 feet (1500 to 2100 meters). It is usually possible to prevent HAI by ascending slowly and allowing your body to adjust as you go.

At what height do you need oxygen?

For best protection, you are encouraged to use supplemental oxygen above 10,000 feet MSL. At night, because vision is particularly sensitive to diminished oxygen, a prudent rule is to use supplemental oxygen when flying above 6,000 feet MSL. So, when you fly at high altitudes, supplemental oxygen is the only solution.
