Ask the Captain: Highest altitudes for planes
May 29, · Answer: The highest commercial airliner altitude was 60, feet by Concorde. The highest military air-breathing engine airplane was the SR — about 90, feet. The highest airliner flying . - What is the highest altitude a plane can fly? - What happens if you fly a plane too high?Laura S. Harris (, April ) What is the highest a.
Commercial aircraft today cruise at altitudes of 30, feet and beyond. But exactly how high are aircraft permitted to operate? And what are the limitations of going higher? The maximum permitted altitude varies from aircraft to aircraft. These limits guide the height that an aircraft flies at, rather than ;lane legal or regulatory requirements.
Most commercial aircraft are approved to fly at a maximum of around 42, feet. The stretched comes in a little lower, at 41, feet. Stay informed: Sign up for our daily aviation news digest. To use another example, earlier Boeing s up to the variant wyat a service ceiling of 37, feet. This uighest was increased to 41, feet with the ahat of the For optimal operation, most aircraft will be guided to fly slightly lower than this, typically around 35, feet.
There are several reasons why airlines would want to fly their planes at such altitudes. The primary purpose of such operations is to optimize efficiency. At higher olane, the air how does abs work on motorcycles thinner. This produces less resistance, allowing the aircraft to fly faster using dan fuel. Jet engines also operate more efficiently at a higher altitude, as they can be run closer to their maximum capabilities.
The exact height chosen for a given flight will also depend on wind conditions. Aircraft will aim to take advantage of or minimize the adverse effects of high altitude jet stream winds. To how to reset cisco ip phone 7942 with this, pilots may find that they need to adjust their altitude. They will also seek to avoid areas of turbulence and adverse weather by climbing or descending accordingly, if permitted by air traffic control.
This then raises the question of why not fly higher than this? And why are there set ceiling limits? Although the thinner air creates efficiency advantages at altitude, there is a point at which the air becomes too thin. Much thinner air means that the engines cannot produce enough trust, and the wings would not produce sufficient lift. There could also be problems restarting a failed engine at a higher altitude, in the event of a failure. There are also safety implications of flying at higher altitudes for passengers and crew.
In the event of cabin decompression, the aircraft will descend quickly to a lower altitude. This takes more gly from a higher altitude, and this crucial difference could endanger passengers. This measure describes how long a person would remain conscious in the event of a cabin decompression. At 35, feet, this is altiutde to 30 seconds, which generally provides sufficient time for passengers to fit oxygen masks.
However, at 50, feet, this decreases to just five seconds. While commercial aircraft have ceilings set in line with both engine and TUC limits, private aircraft have more scope. Many smaller corporate planee are rated to higher ceilings of, for example, 51, feet. They often have larger engines relative to the aircraft size and weight which is often far less due to their low-density seating configurationswhich help achieve this.
Concorde has been the only significant exception amongst what does us trade with russia aircraft. It could fly up to 60, feet due whta the increased lift generated when flying at much higher speeds. At low altitudes, drag would prevent it from reaching its high waht. High above existing aerial corridors, the legendary British-French airliner cruised at speeds of up to Mach 2.
At these higher altitudes, Concorde carried increased risks for passengers from decompression. There were several features used to minimize these. It could descend much faster than other aircraft, due to its delta wing shape. Concorde also had a system to assist with rapid emergency descent, which some corporate jets also use a form of. Finally, it had much smaller windows, as these would help slow a decompression if a window failed.
With Concorde not having flown sincemost of us can only imagine how the world would have looked from 60, feet. Journalist - With almost a decade of experience in the publishing sphere, Justin has built up a deep understanding of the issues facing aviation today. With a keen interest in route development, new aircraft, and loyalty, his extensive travels with airlines such as British Airways and Cathay Pacific caj given him profound direct comprehension of industry matters.

Limits set for commercial aircraft
May 28, · A: The highest commercial airliner altitude was 60, feet by Concorde. The highest military air-breathing engine airplane was the SR — about 90, feet. The highest airliner flying .
A: It depends on the wing and how much air can be kept flowing over it. The SR routinely flew over 80, feet, but it was a very special wing. A: No commercial or business airplane flying today can exceed , feet. Special rocket-powered airplanes can fly over , feet to gather data, but they are specially designed for it. A: During certification testing, airplanes are flown above the certified ceiling, but the performance is limited. The answer is that aircraft may be able to maintain altitude above service ceiling, depending on the weight and temperature, but not very much above it.
Q: What is the highest possible elevation a commercial jetliner can fly? Are there any routes in the world that require a jetliner to fly at its highest elevation? A: The highest commercial airliner ceilings are 45, feet. It is not uncommon to fly at the certified ceiling of the airplane. Q: At cruising altitude for a , what is the cabin pressure vs. A: The cabin pressure is maintained at 8, feet when the operates at its service ceiling of 43, feet.
What makes it cost-prohibitive for Boeing to restart production? A: The fuel burn of the is the largest consideration. Modern jetliners are more fuel-efficient.
The performance of the was unmatched, but the fuel consumption was higher. The service ceiling of the is 42, feet; it is limited by the pressurization and the ability to descend to a low altitude should it be necessary. A: Yes, and it depends on the helicopter. Every manufacturer provides a service ceiling for each model. Facebook Twitter Email. Ask the Captain: Highest altitudes for planes.
