(c) Over other than congested areas – An altitude of 500 feet above the surface except over open water or sparsely populated areas. In that case, the aircraft may not be operated closer than 500 feet to any person, vessel, vehicle, or structure.
What is the lowest altitude a commercial plane can fly?
The Federal Aviation Regulation (FAR) Part 91.119 indicates that, except when necessary for departure or landing, the minimum altitude over urban areas is 1,000 feet above ground level (AGL) and 500 feet AGL over rural areas.
How fast can a plane fly at low altitude?
Commercial aircraft are capable of, and in fact, do, operate at high speed (>250 knots indicated airspeed [KIAS]) at low altitude (below 10,000′ above ground level) worldwide.
What is the slowest a 747 can fly?
A Boeing 747 under standard conditions must be going 296kph (184 mph) to take off. Additionally, weather factors can affect the ground speed need for takeoff. For example, a headwind will reduce the ground speed needed.
What height do commercial planes fly?
Limits set for commercial aircraft
Although, of course, air traffic control in each airspace has ultimate authority over an aircraft’s precise altitude. Most commercial aircraft are approved to fly at a maximum of around 42,000 feet.
Why planes do not fly over Tibet?
According Debapriyo, most commercial airlines avoid flying directly over the Himalayas. This is because “the Himalayas have mountains higher than 20,000 feet, including Mt Everest standing at 29,035 feet. However, most commercial airplanes can fly at 30,000 feet.” … The Himalayan region has almost no flat surfaces.
Why do commercial airliners fly at 35000 feet?
The “sweet spot” of flying is regarded as between 35,000 and 42,000 feet – too high and the oxygen becomes too sparse to fuel the engines, too low and the air resistance is greater. This optimum height is linked to the usual weight of a commercial jet – that is, heavier planes fly lower, and lighter higher.
What is the slowest an airplane can fly?
Technically this is the so-called ‘stall speed’, where air passes over the wings fast enough to sustain altitude, and for small planes this can be less than 50km/h (31mph). But at such low speeds, the aircraft is easily destabilised, and could fail to leave the runway.
Why do planes fly so low sometimes?
Why do the aircraft fly so low? Aircraft have to fly low in order to properly line up with the runways and execute safe landings. Aircraft may, however, appear to be lower than they actually are because their large sizes make them look closer.
What is the slowest plane in the world?
The slowest powered plane ever flown (even if it was human powered) was the MacCready Gossamer Albatross. And it was very slow – topping out at 18mph.
What is the biggest plane in the world?
By the numbers, the Stratolaunch — code name “Roc” — is the largest plane ever built. Its wings measure 385 feet across, longer than a professional football field. Its twin fuselages are 238 feet long, while its tail height is 50 feet.
How high can a 747 fly?
The Boeing 747–8 has a ceiling slightly over 43,000 feet MSL (above mean sea level). NOTE: The FAA levies strict rules and tests that aircraft manufactures have to abide by and conduct if an airliner is to fly above 40,000 feet.
How fast does a commercial plane fly mph?
The typical cruising airspeed for a long-distance commercial passenger aircraft is approximately 880–926 km/h (475–500 kn; 547–575 mph).
Why do planes fly at 38000 feet?
Those traveling in all other directions fly at even ones (32,000 feet, 38,000 feet, etc.). Planes traveling in the same direction fly 2,000 feet above or below other planes near them, to ensure they don’t collide or even get near each other.
What is the temperature at 35000 feet?
At 35,000 feet the air temperature is about -54C.
Why do commercial planes fly so high?
The reason aeroplanes fly so high is due to improved fuel efficiency. A jet engine operates more efficiently at higher altitude where the air is much thinner, allowing an aircraft to travel faster whilst at the same time, burning less fuel.
