At what altitude does a Boeing 737,777,747 need to be for landing???

Answer 1

What altitude? The altitude of the air field would be the number where the wheels hit the ground (give or take a few feet).

Answer 2

Slightly above the ground! Not trying to be cute, but you know that it wouldn't get to the runway if it got lower than that, - and it would be a "crash"!

Now in the "traffic pattern" there is a prescribed altitude for all aircraft, however the airliners generally are cleared from the "holding pattern" (if there are a number waiting to land), -- for a nearly streight in approach, and generally they start that from around 2500 feet. (which is generally 5 miles or so out). This gives them plenty time to make sure they are in proper position, airsped, etc. to make nice landing (It scares the passengers a whole lot less)! This also lets them stay high enough that they are pretty well above all the homes and urban areas around the airport (this also gives them a little leeway,- in case of some kind of in-flight emergency). Pilots have an old joke that "any landing you can walk away from,- is a good landing".

The small aircraft (generally referred to "private" aircraft, - have a 700 foot "pattern" about 1/2 to 3/4 mile from the airport, and don't go lower till they are making their "crosswind turn" and then the final turn" to line up with runway to land. In other words the airpland makes two left turns, - starting out pointed the opposite direction of landing traffic, -- (generally as this is the "standard approach procedure"). Known as a left "hand pattern". However sometimes the "right hand pattern" is used if there are obstructions like towers and mountians (or schools or hospitals)on the other side of the airport! This keeps the big ones and the little ones well apart!

Answer 3

I've been a passenger on a Boeing 767 landing at El Alto, in Bolivia, which is at an altitide of just over 13,000ft.

El Alto is the main airport for La Paz and is likely the highest airport serviced by Boeing airliners. Its possible that Lhasa, Tibet might be at a similar altitude.

Generaly speaking high altittude is not a problem for landing. Taking off in a reasonable runway length is another matter...

Answer 4

Typically airplanes land at an altitude of 0 ft. If they were any higher, well, they wouldn't be contacting the runway. Any lower, that would be in the ground. Altitude is set by adjusting the altimeter for the barometric pressure of the landing airport, so that you know you are actually at zero feet.

Answer 5

What is the question? --You want to know the correct height-to-distance ratio on a 3º approach slope? Look on some ILS approach charts. From those you can get elevations of the airport, the touchdown zone, the landing threshold, & the electronic glideslope at the final approach fix and over the outer marker beacon. --Sometimes over the MM and IM, too. Nautical mileage is also shown. So you can figure out the ratio for approaching to land. You don't need any information about the correct angle of attack.

Answer 6

Field elevation is usually a pretty good place to start. To initiate a landing it would vary from airport to airport and pilot to pilot, and an aircraft that large is always going to be under direction from Air Traffic control.

Answer 7

it depends on what speed the 737 is going at... landing speed is usually around 170 kts with full flaps. i had a pilot tell me advice that for every three miles (nautical/statute?) you should be 1,000 feet in the air. so the altitudes will vary

hope this helps

Answer 8

I really couldnt tell you the exact altitude for landing. Because its can be different for each airport. and sometimes its different for reasons as to why you are landing?

Answer 9

Field elevation.

Answer 10

Close to the ground helps
