Early Air Travel Very early flights for passengers were usually for pleasure rather than travel. It was such a novelty! As far as I know, t…he first scheduled flights for the public began to operate in about 1912, but only over short distances. Anything much more than 30 miles or so was rare at that stage. Austria claims to have been the first country to have had regular scheduled long-distance air services. Apparently they started to operate early in 1918 on the route Vienna - Krakow (now in Poland) - Lviv (now in the Ukraine). In 1918 these places were all in the Austro-Hungarian Empire. Unfortunately, I don't have the mileage, but the distances would have run to some hundreds of miles. NOTE. Please check this, as it seems very early for the kind of distances. In the early days, flights seldom operated every day of the week and air travel was very expensive. Some years years ago I saw a replay of a film made in 1938 (so on eve of WW2) by British Imperial Airways of a flight from London to Bombay (now Mumbai) and Delhi, both then in British India. From what I remember the journey took three days. The passengers spent each night on the ground at a hotel and all dressed up terribly elegantly for dinner. :)
Answer \n. \nFAA sets the rules. They're designed to reduce collisions. East flies at odd-000 feet and West flies at even-000 feet up to 29,000, then they alternate ev…ery 2,000 feet.\n. \nWith better radar, better computers, and onboard collision avoidance equipment, controllers are able to reduce the vertical separation and accommodate more aircraft\n. \n IN ADDITION: \n. \nThey fly at a specific altitude because the airlines save money on fuel if they fly between 33-42,000 feet. The air is thinner here and the plane uses less fuel to fly from one distance to another.
Generally yes. There is less drag at higher altitudes, and thus better fuel economy, right up until the airplane can't get enough air to burn with with fuel to get the p…ower needed to go faster and higher. Of course it takes extra fuel to get up there, so only long distance travel is done at high altitudes.
The DC-3 remained the primary commercial carrier until the introduction of the Boeing 707 in 1958, and the 707 ruled the airways for the next 20 years. …Answer While the DC-3 was certainly very popular due to the large number built during the war, the DC-7, DC-7, Lockheed Constellation, and the Lockheed Electra were the "state of the art" prop and turbo-prop aircraft just prior to the advent of the pure jet transport.
Usually around 600 MPH
Passenger airplanes cruise at an altitude of 11 000m on long flights. In which layer of the atmosphere do these airplanes cruise?
It really depends at what latitude the flight is operating. The lowest layer of the atmosphere, the troposphere, extends up to an altitude of about 23,000 feet (7km) at the po…les, and an altitude of about 60,000 feet (17km) at the equator. Therefore, at the poles the aircraft would be flying above the troposhere, in the stratosphere. At the equator, though, the airplane would still be in the troposphere. As you go north or south from the equator, the maximum height of the troposhere (known as the tropopause) generally decreases from 17km to 7km. However, there are notable 'step' changes in the height of the tropopause, where there is a large change in temperature. This causes the high speed winds known as jetstreams, which aeroplanes use to improve journey times. At any location, the height of the tropopause (i.e. depth of the troposphere) is a function of temperature and air pressure/density. As it is warmer and pressure is lower at the equator, the tropopause is higher here than at the poles.
A commericial airliner flies at around 35,000 feet. (30-40,000)
If the elevators are up, then the plain goes up but if they are down, the plane goes down.
One of the main reasons is to conserve fuel. Airplanes can fly at any altitude and speed. However, airplanes generally tend to fly at high altitude to conserve fuel. This make…s the plane more efficient and keeps the operating cost down. Of course, an airplane can not always fly at max altitude at every flight. It may have too much weight or the distance it travels may be too short. So there is always a trade-off as to how they will fly the route.
Ailerons turn the plane left, or right.
Higher altitude air is less dense. Less density means less air; less air means less friction, and less friction means a higher speed.
Why do you not experience a drop in air pressure when you travel via airplanes even though airplanes travel at high altitudes?
It is because an aeroplane's cabin is pressurized, meaning that it is sealed off from the atmosphere. This prevents air escaping and keeps the pressure constant.
The only real limit for jet airplanes is the amount of air available for the engines to maintain compression, combustion, and thrust. Once the air becomes too thin, the aircra…ft can't go any higher under its own power.
A ruler or tape measure is used to find the height of an airplane, usually while it's on the ground. When it's flying, an altimeter is used to find its alt…itude ... its distance either above ground or above sea level.
In short they don't. Small light unpressurised aircraft fly relatively low, so the air pressure is acceptable. Large aircraft (heavy jets etc) use a pressurised hull, air …is pumped into the cabin which is kept at an acceptable density. This is why you hear about explosive decompression, and why aircraft flying at high altitude have oxygen masks which drop from the cabin roof for each passenger in the event of decompression. Without them you would die of oxygen starvation.
normally above 10,000 feet and below 41,000 feet above sea level
